View Full Version : Help with my Slow Stick

Hey guys, this isnt exactly modeling science, but maybe you can give me some help.

I just put a geared 400 on my Slow Stick, and it has ALOT of torque. So much so that it effects flight. The plane will actually start to roll to the left, despite having that huge Slow Stick wing on there.

I was thinking about putting some weight on the right wingtip, but I really dont want to make the plane any heavier. Do you think there is a way to counteract the torque without ailerons?

Maybe you guys could give me some ideas?

BTW-
My setup is as follows:
GWS EDP-400 with E gear
GWS 11x8 prop
8 cell Hecell 1100 NiMH
or
8 cell 1600 NiMH (havent flown with this one yet. We have a retired Zagi, and I will be using some of the batteries from it.)
1 no-name japanese servo (elevator)
1 GWS pico BB servo (rudder)

Thanks,

Brian

As you know, ailerons control roll. You can offset the aileron trim or use an aileron trim tab to compensate for the torque roll at one flight condition. This compromise compensation will only work perfectly at one airspeed, one rate of climb or level flight. You can get beter compromise compensation by mixing throttle with aileron if you are using a programmable transmitter. With practise, manual compensation using the aileron stick can be achieved but it takes a lot of concentration to fly this way.

Well, since the the slow stick doesn't have ailerons, the best way is to give the motor some right thrust. I don't know how to do that with GWS gearboxes, but that is your best bet. My Lazy Bee was just the same way with the recommended motor angle. After increasing it with 2 or 3 more degrees to the right...it was a whole new airplane.

I guess I will just bend the tube to the right a little bit.

Thanks for the help!

You need at least 3 degrees right and down for the plane to be well behaved. Careful when you bend as it is easy to kink the aluminum! I prefer to cut a hardwood plug with the thrust correction and then epoxy that into the end of the tube so the motor is then "stick" mounted! I make the stick long enough so it extends about an inch past the front wing mount which adds a lot of strength in case of a crash!

Do you just epoxy the wood inside the fuse? Also, what size is the aluminum tube?

Thanks,

Inside of tube is 9mm square or about 5/16"! Just epoxy the wood inside the tube. I use a bigger piece and plot the 3 degrees right and down on the stick the length of the motor mount then saw the rest of the stick down to the 9mm size and epoxy in place! 3 degrees is about 5/16" offset in 6"! You want it pointing right and down when looking toward the front of the plane!
