What’s the build ratio of 9s vs 9As? I’m buying a 9 but there doesn’t seem to be many of these out there. Just curious why the tail dragger version is less popular. Higher insurance maybe?
There are more people that fly nose wheel planes than tail wheel types, the insurance is higher and less training required.What’s the build ratio of 9s vs 9As?

Yeah I get the non-aerobatic aspect. But not everyone wants to do rolls and loops. I was more curious why of the 9 models why the trail dragger is less popular. I guess if you don’t want to do aerobatics then way bother with the more difficult version to fly/insure?Also many people who tend to like tail-draggers also tend to like aerobatics, pushing them toward the -7 or -8.
I owned a Warrior before my -9A. When people familiar with certified GA ask what the -9A flies like, I tell them it’s a 2-seat Cherokee that does 160 knots.The A models always remind me of bubble canopy Cherokees![]()
Same here. And pretty much the only people who think my -9A could look more cool are RV pilots.For my mission, a tailwheel would be all downside (higher insurance, worse ground visibility, more challenging crosswind landings), and I don't particularly care about subjective opinions on the "cool factor".
FYI: the 9a is my favorite of the van's fleet. I'm taildragger endorsed but still a tricycle boy LOLI am building an 9A i really like the way the 9 looks but got quoted an extra $1000 a year in insurance. Thought that was a bit much for the cool look
I don’t really get the appeal of the -9 vs a -7.. the -9 is slower than the -7, even with the same engine, and both are so easy to fly.. I find the -9 stalls maybe less than 5 knots slower than the -7, yet goes 10+ knots slower on the top end. What -9 stall speeds are y’all seeing? Approach speeds feel the same to me, yet with a -7, you can loop and roll it. Plus the shorter wing fits in a hangar easier.FYI: the 9a is my favorite of the van's fleet.

I found a 9 that I’m going to buy. Already finished the pre-buy and should close on it next week or so. Funny you are going with the 8. That was my first choice until I went and saw a couple of them. It was tight fit for me at 6’5” and the back seat is even tighter. We have 3 small dogs we needed more luggage room for the pups. But I love the looks and speed of the 8. Oh, and I also think TWs are sexier. I just sold a T-tail Piper Lance that I owned for 5 years. The pilots who owned them said they looked sexier on the ramp than the straight tail versions.The both have their place. I prefer the TW models for two reasons, looks and better suited to grass strips which is where I mostly fly to/from.
Personally I think the TW version look is much 'sexier' (is that bad to say these days?) than the nose wheeled RV series, but hat is entirely subjective. I also feel they are a better mount for landing on grass strips than a nose wheeled version.
I realize there are gear upgrades that help, but over the years I have read about several nose geared versions collapsing/bending when landing on rougher grass strips. If I only flew from hard surface runways, whichever one I got for a fair price would be my choice. As has already been mentioned, insurance is also a consideration. TW insurance is definitely higher, but after a few hundred hours it does trend downward.
The other consideration is if I lived in a high wind area as say the Dakota's or Wyoming, I may be more inclined to go with a nose wheel. TW's can get to be a handful on landing in high winds.
This is all from experience owning both (although not RV's). But I do have a deposit on an RV-8! I just sold my 172 after owning it for nearly 40 years and now have a stable of TW aircraft. Probably will regret selling the 172 as I get older, but for now it's a TW for me.
As a final comment, the RV9/9A were my main consideration for my next plane purchase until my wife sat in one alongside the RV8. I was shocked that she preferred the -8 over the -9's! She didn't have to convince me since I really wanted a tandem but thought she would prefer the -9! 43+ years together and I thought I knew her better! LOL So, the search for an -8 was on! Found a nice one with the help of a fellow poster on here, deposit paid and now I am searching for hangar space. Hoping to get it home by the end of May.
Good Luck with whatever you decide. It boils down to whatever makes you happy!
Coming from the certified world and from a high performance/complex aircraft I can tell you the TW RV9 is still way cheaper insurance, even considering the fact that I don’t have my TW endorsement yet. I’m happy to save $700 for the first year and as I build TW time this will come down a lot more in the coming years. Not to mention the maintenance cost of an experimental vs certified. Personally I just like the looks of the TW much better and perhaps after owning the 9 for a while I’ll move to a 7…if I feel the he need to go a little faster and do aerobatics. But for now it’s mostly about short cross countries and saving money.I am building an 9A i really like the way the 9 looks but got quoted an extra $1000 a year in insurance. Thought that was a bit much for the cool look
Coming from the certified world and having no TW time, the 9 is still cheaper believe it or not. It just comes down to personal preference and that’s why I love the Vans lineup, there are so many choices.I am building an 9A i really like the way the 9 looks but got quoted an extra $1000 a year in insurance. Thought that was a bit much for the cool look
Agree, but I’m not really into aerobatics at this point. Since this is my first TW plane I thought the 9 fit my mission perfectly. Short cross country flights at the same, if not a little faster, speeds than the Piper Lance I was flying.Also many people who tend to like tail-draggers also tend to like aerobatics, pushing them toward the -7 or -8.
I’m coming from the tricycle gear world as well and is all I’ve flown since I started 10 years ago. But I wanted to try something different and always loved TW planes.I chose the -9A because of comfort. I was trained in tri-gear C172's and went with what I was familiar with.
BTW, my -9A is SO easy to fly and land! Go figure!

I have not flown a 7A but I am sure it is a great plane. I built a 9A and am very happy with my choice after 1,300 hrs.I don’t really get the appeal of the -9 vs a -7.. the -9 is slower than the -7, even with the same engine, and both are so easy to fly..

I have to respectfully disagree with this opinion. I mostly fly with multiple RV7s often in the past 15 years. The guys with constant speed props do, most assuredly, out climb me. As far as speed, well. . .again, those with constant speed props will be faster. I equate that to the prop, not the airplane. Honestly, the airframe differences are most notably different when incorporating altitude. Lower altitude (below 8,500 msl) the RV7(A) may be slightly faster on the same power setting. Above 8,500, the 9(A) wing comes into its own.I don’t really get the appeal of the -9 vs a -7.. the -9 is slower than the -7, even with the same engine, and both are so easy to fly..

My -9 background only consists of three -9As.. one 160 FP, one 160 CS prop, and one 180 Injected CS prop version. The 160 hp versions seem to go 150 to 155knots TAS. The 180 goes 158 - 160 knots TAS. I’ve flown them as high as 13,500 feet, WOT, and they seem to fall asleep up there. The sweet spot seems 10.5, maybe 12.5 if it’s light. Dame with the -7, but I see 165-168 knots true.I have to respectfully disagree with this opinion. I mostly fly with multiple RV7s often in the past 15 years.

I have a 180 hp IO340 with a catto. I would love to someday put a constant speed on it and see how it flies (all I have to do is pop the plug on the crank and install the equipment). Of course there is a weight issue that would change the W&B dynamics if I do. I honestly think I would be pretty close to flying the same as the 7s with CS.
You approach at 55 knots? Is that power on and deep on the back side of the power curve? I used to fly into a gravel strip and would cross the fence at 61 knots.. I don’t think I could come in any slower, but perhaps out indicated airspeed aren’t really comparable at that low range. What Stall speeds do you get?I have not flown a 7A but I am sure it is a great plane. I built a 9A and am very happy with my choice after 1,300 hrs.
I built the 9A as I operate out of a short sometimes challenging strip and I decided the 9A would give a better safety margin than the 7A. I comfortably approach at around 55 kts which is just less than 1.3 * stall (Vans figures). The comparable figure for a 7A based on Van’s stall figures would be about 65 kts. which is too fast for my strip. Pilot reports I have read over the years suggest that the 9A is more controllable at low approach speeds. I certainly find that at 55 kts my 9A has more than adequate power in the ailerons and elevator to handle the significant mechanical turbulence and wind shear I often get on my strip.
Using Van’s figures the 9A (older style Hartzell) has a top seed and cruise about 3 kts slower than the 7A (BA Hartzell?) both using 160 hp. This could be largely due to the BA Hartzell being a couple of kts faster.
My comfortable cruise with an 0 320 (carb) is 150 to 153 kts @ 6.8 to 6.9 Us gal/hr

My stall is 44KIAS. I too will cross the fence at about 55 KIAS for short fields, otherwise about 60 KIAS. Much faster than that and it will float forever.You approach at 55 knots?

Yup. I'm telling you, only taildragger RV pilots think it needs a tailwheel.And as an anecdote, the line kids at every FBO I've gone to while traveling have always said some variant of "cool plane".
My numbers are exactly the same, and I can confirm the floatiness if much above 60 kts.My stall is 44KIAS. I too will cross the fence at about 55 KIAS for short fields, otherwise about 60 KIAS. Much faster than that and it will float forever.

No throttling back on mine. Once I lift off, the throttle is full forward until descent. I do fly LOP. Well, PEAK just on the LOP side. Mixture to control fuel. Being a fixed pitch prop the RPM is, well, whatever it is! This lets me cruise around 170 mph (sorry, that would be 148 knots for all the knotheadsMy -9 background only consists of three -9As.. one 160 FP, one 160 CS prop, and one 180 Injected CS prop version.

I think your 340 is a pretty sweet combination.. the CS prop seems to help them climb but I don’t think it makes it any faster, unless you have been throttling back to set RPM. I fly my -4 with a fixed pitch prop, but I use manifold pressure to set power, I don’t throttle it back to set rpm. My sweet spot for altitude is 12.5 to 14.5. I often fly as high as 17.t, but it gives up a few knots up there, although the range goes up..
What speeds do you see with your -9?
Except for the "flip over" surprise? Or has that been ironed out?Tricycle gear airplanes, including RV "A" models, are easier to land with fewer surprises, and insurance is generally cheaper.
Judging by insurance rates, it's either been ironed out or not nearly the risk it is made out to be, especially on paved runways. I have had no issues on grass either, including some rather rough strips. Stick full back. ALL. THE. TIME.Except for the "flip over" surprise? Or has that been ironed out?
Good performance info. Thanks. Btw - total Vans newb question. But what’s an Ed Sturba?I fly my approaches at 60 KIAS. As chris says VS 1.3 is 55 KIAS, and likewise I am over the hedge at 55.
The stall full flaps on mine is 42-44 KIAS.
I fly from a 475m / 1556ft grass runway, with reasonably clear approaches.
Ive got an Ed Sturba and a 150hp engine. My cruise at 2000ft amsl set 2450 rpm at 15c/60f is about 142KIAS with the wheel spats/wheel pants on. I plan to get up to 8000ft or more this year on some longer distance flights as I now have my G5s configured to show TAS, and see what TAS I actually get.
Edited to say I love the 9A as I really dont have any worries on runways with crosswinds, I quite like the visibility taxing. That said, I would rather have a tailwheel aircraft. RV tailwheels look better (in my opinion!) and no need to consider the nosewheel all the time when taxing/takeoff/landing.
Those cruise numbers are pretty good. I’m hoping for closer to 155kts TAS with the 9 I’m buying. It has a 160hp and a constant speed 3 blade whirlwind prop. I’m ok burning just under 10gals/hr. That’s still 4-5 gals/hr better than the Lance I’m selling. Since I’ll be flying a TW the slower approach speeds will be helpful. I can still get in trouble with a bad landing technique but hopefully that slow I’d have time to recover.No throttling back on mine. Once I lift off, the throttle is full forward until descent. I do fly LOP. Well, PEAK just on the LOP side. Mixture to control fuel. Being a fixed pitch prop the RPM is, well, whatever it is! This lets me cruise around 170 mph (sorry, that would be 148 knots for all the knotheads) burning around 7-7.5 gph. I have cruised as fast as 190 mph (165 knots) at 9,500 ft on one occasion. That was racing a storm front to get over it and in front of it. That speed I was NOT LOP, but even ROP I was still only burning 9.9 gph. In comparing the 7 with the 9, I will reiterate my previous post. Altitude is the 9s friend! If I stay down in the 4,500 to 6,500 msl range I do believe the 7 is slightly faster at similar power settings. At altitudes above 8,500 I believe the 9 will perform side by side with a 7 at similar power settings, and perhaps even a bit faster.
As for the others discussing stall speed, my plane is similar to the others who have posted. On final approach around 80-85 mph (69-73 knots). Touchdown I try to get it down to 60 mph (52 knots). Stall is right around 52 mph (45 knots).
9A, solo weight and smooth air, 55 kt is a comfortable sort field approach speed with “normal” approach throttle. I fly the AoA which starts beeping about 55 kt and I am careful to avoid getting slower (excessive sink rate) till just above the ground.You approach at 55 knots?

Full flap?Wow, the two-9As that I recently flew stalled at 50 and 58 knots.. the heavier one stalled higher.. but perhaps the airspeeds just aren’t accurate at higher AOAs..
I delete my post.. I need to go back out and fly it again to verify.. I seemed to recall the stall speeds were close to -7 numbers, but now you guys have me second guessing myself.. The -9 really is a sweet little machine, I just prefer the additional sportiness of the -7..Full flap?
It might help if I spelt it correctly lol. Sorry Ed. Its Ed Sterba - the propeller manufacturer. Its a fixed pitch wood propeller, 68 x 78. (two blade).Good performance info. Thanks. Btw - total Vans newb question. But what’s an Ed Sturba?
Wow, glider tows in a Champ. Must have been an experience! I did the TW endorsement in a Champ, and flew a Pawnee with 235 hp towing gliders for a few years. When it came time to choose an RV model, I wanted to build a -14. Definitely some disadvantages like insurance but for me, more fun, which is my main mission.When I was looking to buy several years ago, I advertised here on VAF for either a 9A or a 7A. I honestly didn’t care which but a 9A that met my goals came up first. I passed over the few tail draggers that responded. I think the tailwheel airplanes look cool...very classic. I have a lot of hours in a Cub and flew glider tows in a Champ years ago. No desire to own another tailwheel airplane. Other than looks, they offer me nothing that enhances my flying experience.
Mike Seager taught RV9 stall numbers are basically RV7’s minus 10. My experience confirms that. Full flap stall for me solo is about 39-40KIAS. I aim for 55kts on short final, always power off (if I’ve done my intended approach correctly). Any more airspeed than that and I’m floating forever or bouncing the landing with those long -9 mains.I delete my post.. I need to go back out and fly it again to verify..

Again, Tailwheel endorsement is like an instrument rating....it only makes you a better pilot stick and rudder and you fly more coordinated because you have to. So glad I did it.
Huh? Did you think that you didn't need to fly coordinated before you got your TW endorsement?
If you weren't already flying coordinated it says more about your flight instruction than it does about where the wheels are mounted.
Hahaha. Touche'. Well I think it reflects more on my piloting skills or lack of than anything. At cruise, I don't think most planes like a cirrus or RV need much rudder input, but I found that maneuvering the 180 horse citabria in steep turns or even cruise flight needed constant attention and pressure to be flown coordinated.Huh?

But I mainly meant that on final its critical for tailwheel gear aft of CG to be straight longitudinal with the runway on touchdown. Yep, likely like many, guilty as charged for being lazy on the rudder in trike gear because you can get away with more.
