[QUOTE=milly0812;980009]Haydn, I don't fly planes but wondered why you put £17 servos in such a nice airframe ? I mean you have not scrimpt on the motor or lipos so why the one thing that caused it to crash ? Surely in a machine of that size it must require reliable hi torque jobbies ?
As said I'm not a planker but am interested ,so are electronics not as important as with helis ?[/QUOTE]
You can get away with much cheaper servos / electrics in a plank than what you can in a heli... Obviously more fancy servos are nicer, but a cheaper servo will work pretty well too.
When i started into helis it was a bit of an adjustment to have spend £100's more on gyros, servos and better quality electrics.. For example the servos in a cyclic have to move the entire "Wing surface" (the whole rotor blade) whereas on a plank, its just a small flap that needs to move (elevator/aileron/rudder) so doesn't require as much. Also things like a Helis tail servo NEEDS to be precise and fast, whereas because a rudder on a plank is just plugged straight into the RX, a slower, cheaper servo will do the job.
Another thing is I think Planes can deal with failures more easily... If a motor stops for whatever reason, in a heli its coming straight down and an auto needs to be done pretty well. Whereas a plane, especially when its high up can glide for a much longer time, its much easier too.. as long as the plane is moving forwards, you can still use all the controls without losing altitude or for the equivalent, the "energy" stored in the rotor disk.
I do miss the simplicity of planks sometimes!
