My new glider

I bought this airplane used from a friend in my local RC flying club a few months ago. The model is a Windstar from Thunder Tiger. It is a three channel electric glider with elevator and rudder. The wingspan is about 2 meters. The airplane was old and used a lot. I started by removing all the covering film and replaced some broken wood parts. I rebuilt the nose of the fuselage to fit my needs with a large magnetic battery hatch. I also modified the wing tips and removed the original plastic ones and replaced them with balsa wood. After all repairs and modifications was complete I covered the airplane again using a Oracover, yellow and red on the top side and black on the bottom.

Maiden flight of the BushBeast 2, my new balsa plane

This video shows the first few flights of a new balsa airplane that I have designed and built during this winter.

The airplane has a wingspan of 90 cm and weighs around 700 grams including battery. I use standard RC equipment, no special functions or microprocessors in this one. I built this airplane just to havs something unique and fun to fly with. The plane is built using traditional building techniques. It is built out of balsa and covered using Oracover.

Indoor plane of this season (2015-2016)

Last year I designed the “Stick pusher” for indoor flying. This years airplane is new design. I took all the things that a liked with last years airplane and added some new features, ailerons being the biggest change. I have also moved to a twin boom pusher design to be able to have the motor and propeller more in the center of the air frame, this removes the effect that airplane wants to dive when you increase the throttle. It also makes the airplane fly more symmetrically. The airplane has large control surfaces and is capable of tight loops and turns. It has a relatively large speed envelope for being a small indoor plane, it is possible to fly quit slow, but it can also fly very fast if you want.

APM copter V2 gimabl testing

Here I am testing my homebuilt gimbal om my new APM quadcopter. It is a two axes gimbal based on the same Martinez Open Source gimbal controller and the same Quanum 2208 gimbal motors as the first APM quadcopter. I am not happy with how mush of the propellers that are visible in the video. Maybe a solution could be to extend the gimbal and landing gear further down.  During this flight I used my 13-inch propellers that I cut down to about 11.5 inches.

First flights of the new APM copter V2

There is still a lot of tuning to be done. In the video I fly with propellers that are a little to small (10 inch), this results in sluggish yaw behavior. The 13 inch propellers in the images where to large, they caused the copter to be a little unstable and fly strange due to the low RPM. Currently the camera is hard-mounted, but this copter will carry a gimbal when it is complete. I do have problems with “altitude hold mode” on the APM. Maybe this is because I fly with wrong sized propellers, or there is wind blowing on the sensor.
