Default RE: Electric Racing Development Efforts

Okay, flight session #2 provided my first onboard flight data. I used a TGS 9 x 7.5 prop on the 35-48-1100 on 4S 2350's. What I found out is what I expected. It wasn't enough prop. The speed was about the same as the shorter motor, but the current was down. This points to more available torque from the longer motor. I then changed the timing to high on the Pheonix ESC and it ran smoother and used even less battery. So, it is off to buy more props. The 35-48 certainly runs more efficient than the 35-42. Next set of tests will use the 9 x 7, 9 x 7.5, ad 9 x 9 APC. I may even try an 8.8 x 8.75 APC. The TGS prop was not very impressive. This weeks weather is looking promicing for more flight testing. I'll keep you posted.

I have attached the Eagle Tree Flight Data report. Estimated in flight speed is 94mph.

Take Care,
