That 50 amp esc will be overkill... A 6x4 sport prop with 3s draws around 27-28 amps...
I think we've discussed this motor before over in the Stryker thread. I've been flying this motor on a 6x5.5 @ ~37A. I've only dopplered it, and got about 94mph...but I don't trust it. I swear it was only moving about 80-85mph.

I guess I'll just have to get some video of the Rifle and doppler it for comparison. Hopefully I still have the old Stryker videos.

I know the ESC is overkill, but my other ESCs are 35A and under plus a 80A and 100A. So this one fit the bill. Unfortunately, it's opto, so now I also have the weight of the BEC.

All the components are overweight, the motor, ESC, servos, even the Rx is on the larger side. We'll see what AUW is and take it from there. With a 6" prop, I'm not too worried about hand launching, but a 4.75" makes me nervous.
