I used to have an RV7 that I never really used for IFR. Then, 14 years ago, I flipped to a Baron and flew a fair amount of IFR, which was easy, given the high mass of the plane... 5,100 lbs max gross weight. Now, my partner and I have sold the Baron and I've bought a soon-to-be-delivered RV9 with a great IFR panel... just wondering how comfortable you guys are with actual IFR in a 9...
 
Define this. You're more than likely ok, but....
panel includes G3X, G5, Garmin autopilot, panel mounted i-pad, GMC 507 controller, GSU 25 ADAHRS, GTN 625 NXi, GTX 45R 1090ES, GNC 255A Nav/Com, GI-260Angle of Attack Indicator, GSA 28 Pitch/Roll Servos, GMU 11 Digital 3 Axis Magnetometer, GEA 24 Digital Engine Interface, Stratus 2S Portable...

Now, I need to learn the latest Garmin buttonology... The Baron was a 530W setup with an SL 30 navcom backup...
 
One thing to take note of is how the AP handles staying on course and GP at slower speeds. It’s not as accurate as I like. I try to fly 85 knots after the FAF so that a large pitch change isn’t needed in order to start flap deployment. My AP strays more than I’d like. But overall the equipment works great

I got my IFR ticket in a 9a with the a 430 non-WAAS and a decent autopilot. It flew approaches fine, but I was never comfortable flying IFR other than getting through a layer when needed. My opinion would be to add some form of back-up electrical system if you intend on flying in the clouds regularly. Icing is another concern. A friend who is an experienced pilot and talented builder, just sold an IFR equipped RV 10 and bought a TTX because of icing concerns in the PNW.
 
I am always sensitive to icing issues... While the Baron had boots, alcohol windshield and heated props, I never had to use those features. In the southeast, we dont have to get as high as west coast fliers, so maybe that's what makes it easier here.

How do you feel about stability of the 9 in clouds? Is it fairly easy to hand fly? I get the sense its more stable than the 7 due to the longer wing.
 
I have flown my 9A in actual for years, including a few dozen approaches to 300' and (gasp!) even a couple down to 200 and 1/2. It's a good platform with a capable autopilot - but you must be on top of the buttonology (as always) and keep it stable on speed. I like 85-90 knots down final with one notch of flaps - that way I can easily dump more flaps on breakout for landing, or suck them up and climb out on a missed.

IFR is equally as much the pilot as it is the airplane.

Can't speak to the 7, but I fly my 6 ifr all the time. I've also flown a 9, and think it would be quite a bit more stable. The 6 is a handful without using the AP. It can certainly be done, but its a fair amount of work. As far as icing, none of these planes should even launch if there is known icing. And, yes, that does restrict you in certain areas. Eg. The PNW in winter or shoulder seasons. But it wouldn't matter then if it was a 6, or a 6, or a 9, or a Cherokee, or whatever. Without de-icing, you're staying on the ground.

In most respects, I don’t find flying IFR in my 9 to be materially different from flying IFR in my previous plane (a Warrior). But hand flying a 9 in summer cumulus is more difficult. That’s where you really notice how much less it weighs.
 
Yes. The 9 is one of the more stable RVs for IFR. What instrument panel set up do you have?

If you really want to know how the 9 operates in IFR grab a CFII who is familiar with RVs. I’m open to flying with you if you can’t find anyone locally. Depending on your proficiency in flying IFR single engine airplanes, planning ahead, talking on the radio, anticipating changes, the 9 is very capable.

Like most single engine airplanes, 90 knots at 10 degrees of flaps is pretty standard for holding and flying the approach. Practice in VFR conditions to get known pitch and power settings for descent and approach. Stage 1 for any IFR training program, but it seems to be left out of most people’s training these days as CFIIs want to skip all the skill building and jump right into approaches.

Practice constant speed climbs and descents, as well as constant rate climbs and descents, turns to headings, then combine them for proficiency exercises. These are called “vertical S maneuvers.”
 
I flew the -9a we owned IFR on a few occasions. The only problem I found with it was in gusty turbulent winds. There was a couple occasions we were bordering on crashing upon landing. The light weight with the low wing loading and large flat surfaces combined to make the plane feel like a kite in strong gusty winds.

Although I think the wing loading is about the same as my Warrior, it’s a bit more sprightly in crosswinds. Probably a combination of the wing design and lighter weight. I’ve never felt the difference was material, however. One advantage of the 9 versus the Warrior is that if a landing starts going south, you can get back in the air in no time in the 9. Just cram and go.
 
Got my IFR training and ticket in my RV9A last August 2025. Behind an all glass Dynon panel w/AP and a Garmin 175. Finding a DPE to do the test without legacy VOR/ILS equipment was small challenge but worked out. Used EzIFR for flight school. Love my IFR ticket!

The auto pilot is the real winner of my RV9A build. It takes a bit of workload off when flying around busy airspace near me (DFW & Memphis). The RV9A is a super stable platform and behaves well hands off for a few second or more while I fumble with frequencies etc.

I am impatiently waiting for Dynon to release a new firmware that will support a remote audio panel so I can upgrade to dual comms. Hopefully it’s out before Oshkosh!

I consider my A/P to be essential equipment for IFR, but the 9A is a relatively stable platform considering its weight. My main concern when equipping it for IFR was redundancy, because blank screens in IMC is the stuff my nightmares are made of. In addition to dual independent PFD's, I have a GDL-51 XM weather receiver that has it's own, independent AHRS and pairs to ForeFlight. If God forbid my entire electrical system went dark, I will still at least have a source of attitude and gps speed data on my ipad, to give me a chance at getting back to VMC. Having those two devices mounted and charged is another requirement for me when flying IMC.
 
In the U.K, homebuilt types get flight evaluated for IFR approval - the RV-9 was rated as an excellent platform for IFR.
Wow! You’d be hard pressed to find a bigger -9 fan than me, but that’s just totally silly. What were these evaluators comparing it to, a Pitts S1?!? 🤣

I’d say it’s acceptable.
 
Lot of comments on AP being mandatory. I did my IFR training in my 6, which is certainly more sensitive than a 9. We would often go 2 hours of flying / training and i was not allowed to ever engage the ap, including the briefing and approach setup (quite a challenge in the 6 - look away for 5 seconds and you have blown heading and altitude targets). Also, every 6 months i go shoot approaches. While i do one full approach on AP, the other five and all of the flying in between them is hand flown. Solid 2 hours of hand flying. Yes, it is mentally taxing to fly these birds in imc conditions, but consider it far from unsafe to fly these birds without an ap. That assumes, of course, you keep up your hand flying skills.

Would i fly four hours in cruise in imc without an ap; Not likely. Would i land immediately as in some danger; absolutely not. It is all about your skills and how you have honed them. If you do ALL of your approaches on an ap and have lost the skill to hand fly an approach in turbulence, then yes an ap is mandatory. Problem is, what if it dies in flight? Probably better to just keep skills sharp.

My. 02 getting your instrument rating in an RV-9 vs flying actual in an RV-9 are two different things. Taking it one step further, IMC in a marine layer vs IMC in convective are two different things.

Getting your instrument rating in an RV-9 > Definitely
Flying in stable IMC > Definitely
Flying in convective IMC > Not my cup of tea

The RV-9 is too lightly loaded to provide a stable platform in convective IMC. Unfortunately, that is mainly what we have here in FL. In the winter, we do get some good stable IMC layers where the 9A shines.

Just my perspective, I am sure others will disagree with this.

I believe Yellowjacket came close to answering the OP's question, regarding the "mass" of the plane. Going from a Baron to an RV9 in IMC will certainly take getting use to. I do not own an RV9 but have flown one. I've also flown a Baron, as well as Cessna 310 for many years and when I switched over to the RV world, the stability of the flying in the soup was not there when comparing to a larger airplane like C310 or a Baron. That's going to be obvious to you even the first time you go through a puffy cloud on a VFR day while flying IFR. You just get thrown around more when flying a plane with 1/3 of the gross weight from what you are use to flying. With that said, as you can see from the feedback here, plenty of folk with different risk tolerances fly the RVs in IMC. I think the RV9 and RV10 are probably going to be most stable for IFR due to the wings (and maybe even the RV14), but with the right fancy avionics and autopilot, pretty much all of them will fly down to 200 & 1/2 mile . . .

No doubt it is possible and safe for a proficient pilot to hand fly IMC in the RV's. What the A/P provides is an insurance policy when there is suddenly an extra workload that could distract the pilot. It can also mean you are fresher after a long flight and need to shoot an approach. Whether you want that insurance policy is an individual decision. At work I fly in very capable Bell 429 helicopters (with 2 redundant 4-axis A/P's, Heli-SAAS, etc) with some of the most experienced pilots in the game, and having both A/P's functional is still mandatory for IFR flight, and although not a hard-stop, considered a significant risk factor if not operational for night VFR.

Those are good points and i agree. I would not take an xc flight without my AP. It is mentally taxing and that makes you less sharp on an approach and makes for a real workload challenge at times. My primary point is that it is possible to fly without it and that us non professional folks should endeavor to keep our hand flying skills sharp.

True. Hand flying my -9A through puffy, building clouds is a real chore. I consider an autopilot to be minimum equipment for those conditions, and if the autopilot fails early in a trip (which it once did!) it’s basically time for Plan B—because hand flying that way for hours would be zero fun. There would be times when copying a full route change, which is not that unusual where I fly, would be extremely difficult.

With all that said, it’s not materially worse than my Warrior was, especially if I slow down a bit.

This is the way. I train so that I can hand fly to minimums—and then I fly trips with the autopilot, and only in weather that is VERY unlikely to be at minimums.

It’s always humbling to compare my ground tracks during holds to the Garmin’s. On the other hand, my brain has never completely shut off for no apparent reason, while the Garmin has done that several times. 🤣
