TW 747 Brushless Motor


Here is the brushless motor I put on this. Has a 8x4 prop being driven directly. The geared 370 electric engine does not give the model much performance; the brushless has given it a lift.

Modified TW747 Cessna


This is my TW747 Cessna which I have modified to have a brushless motor. I'm new to electrics and therefore are not exactly sure what motor should be matched with what model and what prop should be matched with what motor. Anyway the TW747 has a geared 370 brushed motor which does not have much spare power (full throttle to climb). I am using 2 cell lipo's so we shall see how she flys. Update - she flys (flew it between the showers). Bit more power than the 370 geared motor, but not the improvement I expected. I am pleased with the result though. I will buy some more lipo's so I can fly more in one session.

OS40LA Stunt


Welcome to June 2010 ;o)

I bought a OS 40LA to put it in a stunter which had a OS 40FP. Actually the first engine I bought off Trademe was a worn out "special". The liner had lost most of its nickel coating!! So thats in the spare parts bin unless the seller feels he misrepresented the engine and refunds me the money. Anyway, I got another LA off a fellow club member. I reassembled the engine and put the stunt venturi from the FP in it and bingo we have a stunt engine. Ran it this morning with a 10x6 Master Airscrew and it appears to run well on the ground. If the weather was better I would take the plane out but alas its too windy.
