Hi all,
Good to hear you all having fun installing your servos. On a x-country or turbulence the autopilot really shines. If i were to do it again, i'd only install the roll servo, save the weight and cost.
Dave webber who works at dynon, and built a jab 3300 powered std gear sonex, developed the autopilot install kits. The new b models have their new control y stick set up so you'd be on your own . Daves legacy sonex was a dual stick set up, thats what we have on our waiex.
A couple notes on our install:
A) we doubled up on the seat pan bottom and back. Much much stiffer , standing on & getting in & out. Also we added a alum 1/8 x1 in x 1 in angle underneath the seat pan both sides. To prevent flex. Dynon reccomends the sv - 32 servo for pitch, and the sv-42 EL (extra long arm) for roll. We didnt have any problem with the pitch servo clearance, the roll arm (EL) was rubbing on the bottom of seat pan with a 200 lb passenger sitting in rt seat. Hence the alum angles did the trick.
B) the EL arm is needed for roll, you can buy this from dynon if you have a std length arm. When you set up the autopilot the program will have you max stick corner to corner of max throw. The std arm will have too much throw and the set up program wont accept.
C) if you have a standard gear(taildragger) be sure to prop up the plane level when trying out the autopilot in the hangar. Even if you set it to current altitude , the stick will go full forward and the autopilot servo clutch will slip if the plane is not level(ask me how i know).
D) dynon has you install a momentary push button switch in the panel for instant autopilot disconnect.
Lots of other autopilot choices depending on your equipment. MGL, Trio, Tru Track, Garmin, Advanced, GRT etc. Take a look at the dynon offerings for the RV series. Some are mounted in the wings. Like gordon is doing. Something to adapt/modify for your particular set up.
I hope you all enjoyed the NFL playoff games as much as i did this weekend.
Fly safe!!
