RE: crazy 8
Hey now,
Sure you can fly it without a rudder, but not without a vertical stabilizer. But why? the weight of the control is ninimal; .32 oz for the servo, .1 for the rod and control horn. Less than a half oz. saved... And just what do you give up for this huge savings of weight? Ground handling, knife edge flight, crabing into the wind, hammerheads, spins, controled landing runs, slow speed control, flat turns, all of this goes away with no rudder.
If this is a weight thing, you're better off not putting a pilot in the model. If it's a cash thing, Blue Bird servos are only fifteen dollars, wire is twenty cents and the horn can be made from a bit of scrap plywood...

RE: crazy 8
no, not weight, don't have a servo (will you believe that i LOST it????) and i want to fly it. was just going to tape the rudder steady and tack glue the pushrod. and ground handling.... no tail wheel mate. but yeah, has anyone flown this plane enough to say? also should the ailerons be flat with the bottom of the wing at neutral or slightly down... i fixed this plane after dad decked it, and he suspected aileron incidence was wrong. thanks dudes!

RE: crazy 8
The C8 actually does steer on the ground with rudder and no tailwheel. Does pretty well in grass, and not bad on pavement.
Suffice it to say, the plane can be controlled in the air if you ignore the rudder.
With the semi-symmetrical wing and flat ailerons, it's kind of tough getting them lined up properly. Ideally they should be lined up with an imaginary line running from the middle of the trailing edge to the point where the airfoil transitions from upper to lower surface on the leading edge. It might not be a bad idea to go with flaperons so you can trim the aileron incedence in the air with the flap channel knob on your radio.
Thanks for mentioning that aileron incedence thing. I just might have to check mine out and see.

RE: crazy 8
that's ok. i stacked it last night. nothing to do with the rudder. a 6x4 and a speed 480 don't produce enough lift to fly! had a 7x5 on it when i crashed fisrt time. oh well, is repairable, but i don't know when i'll do it. might put the motor on my stryker.... thanks for your help guys!
