This is a good tip. Thanks. How high do you jack the plane up? I built my own jack with a threaded central rod. Same height adjustment range as the ones on spruce. I just don't trust myself with lowering those hydraulic lifts... Bounced the car on the ground too many times. Don't want to repeat it with the plane How do you lift the nose? By the engine lift, jack under the prop or pull down on the tail? The engine method should be the official method now but finding a hoist is not that easy around here... Thank you.

I guess I won't have to bother to do the puck rotation test... Lol

Awesome. Thanks for your help guys

Great, thanks. Did you have to remove the bolt on the bottom (shock link) or was it sufficient to remove the top bolt (leg truss assy) only? Can you slide the old donuts off and slide the new ones on and insert the center rod into the leg truss assy with only the top bolt removed? Thanks

Hey guys, I read the other threads and saw the various methods of how to compress the pucks. Many people say that the discs on mains can be compressed by the plane's own weight. Does that hold true for an E? I just wanted to make sure that this quick method is not only for the newer & heavier models ... Thanks guys.

Thanks I'll do that

I think this is where the valves are: https://www.globalspec.com/industrial-directory/bi805_servo_control_valves Finding accutrak seems tough. I'll keep looking...

@Yetti when you say accuflite, do I need to search for just accuflite box or also some valve (bi805?) and more? Thanks man

Thanks. That might simplify my search. Would that require certification battles with FAA or would a simple 337 or STC suffice?

@Yetti thanks, that's an interesting insight. I already have a g5 and a 430W. Any quick add-ons for those? Is there no way to engage the existing servos? All they need is some fresh air leak into L or R servo to steer it that way. I have tons of experience designing solenoid valves for automotive transmissions... I could design an electronic BI805 with my eyes closed... Then replace them with electronic servos once they're dead beyond repair... Yep, message received about FAA certification. I won't charge the bull..

Thanks for all the info. I'll check. Yeah, the whole certification and compatibility stuff is important. No need to buy paperweights that I can't plug into the plane ... Thanks for all the good advice

Hey. Thanks guys for the replies. I googled used Brittain stuff but couldn't find anything. I'll keep looking. It's true, you don't need autopilot. We flew 1300nm all the way to Denver and back... without AP. But, that one 5hr stretch, when wife fell asleep and I decided to skip the pitstop, became tiresome. Especially during the final 2 hrs after sunset... Anyway, I "need" to take care of a few things whereas I "want" an AP. Let's see who's going to win? "Need" vs "want" ;)

Oh awesome. I thought Brittain was long dead and gone. I'll give them a ring. Thanks

Hey all, I've seen many threads about the unavailability of Brittain products (year 2020). Honestly I'm ok with the PC system and I don't really need something that flys instead of me, like doing procedures and what not. Well, I can't afford a new gen autopilot now anyway (And won't, for a while, Lol...) So I'd just be happy not having to obsess about keeping the heading during those 3-4 hr stretches. So I thought what if it was possible to build Accu Trak II or BI 805 servo per original blueprints (and pay anyone their due and put FAA paperwork together). Alternatively, has anyone tried and managed to interface the old PC with a new autopilot system? Did it simplify the installation? Have you saved money doing so? I'm just wondering... I'd be happy if you could give me an answer or direct me to the right thread... Thanks guys. '67 M20E
