Well today I've fitted loosely and tested the radio great. Jan 2017 as a modelling virgin I bought all the Action gear due to googling Smitt Rotterdam and found our top bloke Dave's many contributions
Since then I've acquired very much more Action kit for my stock and today I veered away from Dave's original drawing and changed the P102 for a P107. I'm guessing the 107 was not in production when the original drawing guide was issued?

The only thing I needed to do was restrict throttle output for and aft to a guesstimate starting point and centre the rudder servo.
I'm using the Spectrum DX6 radio that I set up for this all that time ago but I've changed to a cheap as chips Orange receiver

I don't like these couplings but as I started over 3yrs ago and I knew nothing I'm now stuck with them. If I started again today I would remodel the motor mounts for a precise straight through coupling. The motors are Mabucchi triple 5's and again I think I'd change to brushless if starting over.

Also when I bought this kit I intended to use 12volt SLA but I'm going to use 2x3s LiPos
