Barry,
I didn't say no flying over the winter, merely that my '20 would go towards the rear of the forest of fuselages stored at the back of my workshop.
Anyway, I don't live quite as far south as you :) :)

I'm planning on putting micro rudder & elevator servos as near as I can get to the control surfaces. What would be a good mid priced servo for each control how many kg's are needed? I'm thinking over 2kg torque but less than 5kg at 4.8v

Hi Martin, I have used MKS 135, or if you need a bit more power MKS 125, it's always better to have to much than not enough !!

Did you mean KST 125 KST 135 Chris?
I searched mks 125/135 but came up with nothing on HyperFlight
Guessing that around 5.2kg is fine on elevator & go fo the 125 @ 7.0kg for rudder

I'm just about to start building one and there's a few questions I would like to ask
What's the best way to do the elevator, do you go with the long bar in the fin or do you mount a servo in the tail or the fin ?
Where do you fit the servo for the airbrakes?

Thanks
Andrew

Andrew,
I buried my elevator servo in the tailplane, with a short drive to the elevator.
Much more rigid, and simpler to rig as long as you don't let the fuselage connector drop back down the fin ;)
No problems in flight over several years use.

Hi Pete I've been slacking after having big issues after carving the ailerons from the living hinge as advised.
It's now impossible to tape hinge & get enough movement for the ailerons dye to warpage after being detached. Not sure what to do next really only thing I can think of is to put plastic pin hinges to control the gap to a size that will allow them to waggle the required amount.

What type of servo did you fit & what pull does it give you at 4.8v

Peter when joining the tailplane halves did you strengthen it in any way
Thanks
