Has anyone mounted an FM-150 on a Lycoming IO-390? That is what was recommended by Lycoming when I ordered my Thunderbolt engine, and now I am having some mounting “issues.”
I am just surprised that I am having to make these mods when I am using the recommended throttle body. I feel like I am plowing new ground. I didn?t want to be a beta tester . . .
Mods? New ground? Beta tester? For a cable bracket and some hoses?
Chris, are the throttle and mixture cables supplied in Vans FWF kit workable or are new ones in order?
Well, I am confident with the help of Airflow Performance and Aircraft Specialty the issues will eventually be worked through. Nevertheless, with over 50 RV-14s flying, using the throttle body recommended by Lycoming and Van's, plus spending North of $38K for the engine throttle body combination, I am surprised everything is not already sorted. Oh, and it is costing me >$500 extra and a few weeks delay.
I will install the locknuts after I confirm all looks good with my tech counselor.
...and put some 970's on those carefully gooped rod ends
Did the spacer come from AFP? I had not thought about rotating the servo, looks like the best way to hook up the cables. I have a ECI sump that is a little different but running cables the same way should work.
What are the advantage of Airflow performance servo over the skyhwaks that VANs provide.
What is the difference between the Silver Hawk EX-5VA1 offered by Precision Airmotive and the AvStar AVX-5VA1 offered by Lycoming?
Thanks Dan. There appears to be a dearth of information about the AvStar units. I contacted them for maintenance info and they had none, but said they are in the process of formulating ICAs.
Changing out to the longer studs that come with the hardware kit. Got the old stud backed out with the double nut method with a lockwasher between nuts. I have the recommended thread locker Loctite 620.
Long time stud, first time stud changer......
How much loctite is needed?
I found in the service table of limits 25 in-lbs for 5/16 studs but they call it minimum driving torque. Does that mean when I get the stud to 25 in-lbs it?s in correctly or is there another metric to go by?
I am about to install the FM-150 and I have a question. I assume that one needs to buy the following kit from Airflow performance.
https://airflowperformance.com/index.php/product/throttle-mixture-cable-bracket-kit/
This will have all the parts need to put on the FM-150 and the parts to hook up the controllers. Is there anything else I will need.
My real question is why did this kit not come with the engine from Lycoming? Or was I supposed to get it with the engine? It is confusing to me that this kit was not included from Lycoming when purchased.
It sounds like the spacer is definitely needed regardless as to the cable setup. So the studs on the engine really need to be changed out and this could have been done by Lycoming.
Is the FM-150 really worth all the effort? I guess it is too late anyway, since I would have to replace the spider on the top. At least I think.
The only other thing you may find is the fuel hose from the servo to spider may be way too long. I contacted Lycoming about this on my Thunderbolt and they offered to send a replacement and hopefully now ship the correct length. I had already had one made by AS/TSFlightlines in my hose package.
The cable kit is well worth it but as mentioned the mixture cable is too long. I did a bit of an S curve under the panel but will shorten it if I ever replace it. I handled the snorkel differently. I cut off the flange with a band saw, cut off 3/8? and reglassed the flange back on. Just be sure to make square cuts. One nut on the starter was barely touching the snorkel so I just added some heat with a heat gun and pushed it in a small amount to clear.
Is it worth it? I thought the same thing. I have no idea...but the gold anodized components look cool

you mean the red plastic cap on the steel hose fitting? Why is that fitting there instead of a cap? Does that fitting have a use?

We plug off the guage port since its not used. It is uses on some certified applications, but generally not experimentals. Instead of capping the nipple----that should have safety wire, why not just remove the nipple and install a 1/8 NPT hex plug. Simple, easy permanent, and you dont have to worry about a cap and safety wire.
