Have tried a few bit models but have had some problems with not enough power. This model has a 7mm superslick motor with falcon gears. Is made from 3mm depron, wing is a flat plate with the tips elevated and given elevons for stability. Simple depron fus with bits of balsa for the engine mount. Actuator is wound over a large straw.

Takes off from the ground, turns to the left and then straightens up, turns to the right are persistent and need to be corrected. Power off, it has a quick dive and then settles to a stable glide.

Realise now that the bit receiver does not give full switching of the mosfet and need to set the power up not for full voltage.

The wing span is 560mm, the central part is 400mm with the tip panels being 80mm, it has a chord of 80mm, and the elevons are 25mm added on. It was all cut from a single piece of 3mm depron, the tip panels were creased and folded up, a 10mm strip of glass cloth stuck on with acrylic varnish stabilises the joint. The elevons were creased and folded upwards, they then had a smear of pva glue to help hold their position. The fin is 90x60mm.

The bit car is an old one with a new MOSFET, however I found another bit car this week and it is a different design. The MOSFETs seem better, although when I used the forward one a component on the back became hot. I am now using the backwards mosfet. It also has a bridge for the steering with a single coil rather than the twin coils.

(someone)
your plane is great mike..
could you specify what mosfet did you use?
Hello, i got them from Indoor flyer http://www.indoorflyer.co.uk/index....CT&productid=82 , IRLML2502 .

I the current bit cars may have better mosfets than the old ones and may not need to be exchanged. It was odd that the mosfet that seemed to switch the power did not get hot but one on the underside of the board. Not enough knowledge to track down what was happening. I am going to get another car and will try again but using the standard mosfets, the reverse mode one seemed to have less problems.
