Default RE: kadet senior ailerons

Thanks guys for the encouragement. I,ve always loved the Kaydets and there has sure been more radical kit bash's then my Quad.

Here is my other one and it acturally is quite a bit more radical than the quad although at first glance it looks like just another twin engine kit bash. This one is the smaller Seniorita Kaydet which is the smaller stick built just like the Senior. I call it the Oxy-Moron because well, what else would you call a twin engine glider.

The idea was a dual purpose airplane that was a very benign twin for training some of my buddys that could adjust its single engine flight characteristics by an infinite easy adjustment of the out thrust on both sides. Its powered by two Magnum .30FS's and weights in this configuration five pound and two ounces. I built the structure much lighter than even the stock single engine plans with lighter and smaller dimensional lumber.

Now for the good part, The other purpose is to quickly changeover from the twin in under five minutes to a pure glider for aerotowing by another airplane on typically an eighty foot towline. In this configuration it weighs two pounds and four ounces and has a tow release next to the nosewheel. The nacelles are bolted by two quarter inch nylon bolts and the throttle servo is just unplugged.

The real challange was the CG when the engines are dropped off. This is a toughy and of course its neccessary for the airplane to balance at the same spot with or without the engines. This worked out perfectly by a nose compartment in the very tip of the long nose with an access hatch on the bottom and this is where the battery resides when in the glider configuration. With the engines the battery is installed under the stabilizer agine in a bottom hatch. The battery is connected to either end of a long Y to feed the Rx.

The ailerons are full span and fairly deep chord, set up as flaperons on a rotary Tx pot the neutral position is flaps in trail. Then about thirty degrees down flap are avaliable for a very low sink rate. Here is the biggie though the flaps also reflex up above the wing about thirty degrees. This is absolutely invaluable when under tow as most tow planes tend to tow two fast and whipping can develop but this setup makes it a piece of cake. Use a Lazy Ace and a Senior Telemaster for tow. I can fly around a bit as the twin and it does nice basic aerobatics then land and quickly be airborne agine in under four minutes under tow.
