It is perfectly possible to fly big wings with a small tail
but it will probably be very tricky to control and keep in the air.

Moving the linkage to another hole does not alter the centre position of the control surface but by how much it is moved by the servo.

I think you would agree the brushless and LiPo puts the Wing Dragon in a different league, you can actually spend time gliding.

How much does yours...

The 808 is very small and light so its effect will really depend on the size and power of the plane it is mounted on.

If you like to potter about - build light, very light.

Nice Jayhawkjake.
You do need to be careful though. I appreciate that much of the time you are flying over a lake but 'general public' areas are close by.

Flaps can also be brakes. Much over 45 degrees does not increase the lift much but increases the drag so moving a flap between say 45 and 85 degrees gives a variable air brake

It all depends on what you want and the lifting capabilities of your plane.

You did not say how the flight went but does "Rebuild the servo tray" mean it ended in a crash?
If so it must have stopped pretty quick. Did it pull the screws out of the body shell?

Simple answer - yes, but remeber you can break a two blade as well!

A good guide is to go up 1" in diam but keep the same pitch however there is a bit of "suck it and see" to get the best prop.

Provided you add the extra wing area without a proportional increase in weight it will fly slower but you might have to increase the tail sizes to maintain sufficient control.
