Well, the rains parted long enough to test the X-15 and the Tower Trainer togther this morning. Tests went great, with no change in CG on the Trainer and plenty of power to get the job done. Now to complete the launch cradle and actually fly the X-15 under Rocket power!

Here's some more Slow Stick Perversion- this time involving a $9 kite from Harbour Freight and some Slow Stick parts. My partner and Dawn Patrol member Bill Mc Neal (wmcneal) built an Ultralight from one of these kites, some alunimum and a 'G.I. Joe'. Not to be left out, I came up with this design.

Both use "wing warping" to turn- a servo pulls down on one side of the kite causing the plane to bank. It takes a while to get used to, but it is very effective. Bill's depends on the motor to rise and fall, but the Kite Stick uses the elevator, making it a bit more stable than Bill's

The rudder is functional also, but not so responsive. I'll be taking it out in the future. The Stick uses a BP-21 as a pusher and has plenty of power, but if I had it to do again, I'd use a higher kv motor.

Here's a movie we did for Youtube of the Kite Stick. You can see more of Bill and My projects at and

One of my ongoing projects is my X-15 Rocket Plane. It has been on hold due to the need for a "Drop Plane".

I finished my Tower .40 Trainer this week. Powered by a Towerpro 3520-7 and a 50 amp speed control, this plane will have ample power to fly the X-15 up to altitude with no problem.

The X-15 is built from Frank Burke (burkefj) plans, but substitutes the parkjet motor for an Estes Rocket motor. The rocket will be ignited in flight with an old GWS brushed motor speed control with a small 2s lipo. Rocket burns have been timed to 2.5- 3 seconds. We'll fly it sort of like how Mac Hodges flies his B-29 and X-1.
