This is a Laser Arrow. This model is intended to have an IC engine, which mine originally did. It started life with a Magnum 60 Pro, but this was not very reliable so I fitted an OS 90 two-stroke with a tuned pipe. This proved to be a little too much for the airframe and it shook the front of the model to pieces in flight.

I decided to rebuild the model, but to convert it to electric. The green version was the first derivative, which suffered damaged on landing due to the open airframe and a rough landing area, so I planked part of the underneath and recovered the model in yellow. This was using a brushed motor and worked but with all of the NiCads it was heavy.

I then covered the model in red and upgraded the motor and speed controller to be brushless and changed to a LiPo for the power. I also added a seperate LiPo for the receiver with a regulator; this was just to be safe as I was unsure of the BEC with the higher current.

For the cooling, I have drilled four holes around the spinner, to let the air in, and made a hold in the back of the canopy, behind Mickey's head, to allow the hot air to escape.

On the ground the model was drawing 62 Amps.

The model is an excellent flyer, I always get comments on how she looks in the air.
