F-20 Cermark set up info needed
set up info needed for a F-20 by Cermark CG and control throws.
Yep, I bought one listed here on RCU and a JETT 90LX to replace the MVVS.77
not slamming the MVVS but I am a JETT FREAK
BTW the 77 is listed for sale here in RCU turned 11x10 Zinger at 11,4000

RE: F-20 Cermark set up info needed
C/G is 4 1/2" from the leading edge at the start of the wing saddle.
The following throws are recommended for early flights.
Elevator- 10 to 15 degrees
Ailerons- 10 to 20 degrees
Rudder- 15 to 25 degrees
Nosewheel- 10 to 15 degrees
Make darned sure the elevator servo cannot rip loose. The stock mounting is not
satisfactory. The servor comes loose, and the plane "lawn darts" into tiny pieces. [

Don't ask how I know this. Cyclic Hardover's plane was lost too, both on maiden flights. [X(]
I ended up actually bolting the servo through the elevator so it cannot possible come loose.
FBD.
