Did a little testing with the BA3520 790kv on the Mojo 40 today. For me a 14x6 Xoar prop seems to be the ticket. At burst I’m making 1100 watts power drawing 74 Amps. This is a 3300mah 4s setup. Power feels impressive. Hovers at half throttle. Can’t wait to get it in the air.

Sounds impressive!
WyoCowboy flew his BA powered planes often at Ottumwa - fantastic performance (y)

Interesting numbers. I'm getting almost exactly the same wattage on my BA 3520 560kv, about 51A and 1150W on a fresh charge, 2 3S3300 in series, with a 15x6 prop. Had been using an APC 15x6e; just tried the BadAss wood 15x6--slightly better performance, mostly noticed much less cavitation and rip out of hover or high load situations.

Get a Xoar or Falcon 14x7 to try, and you will never use anything else.

I'll give a woodie a try; I definitely liked the APC 15x6 better than the APC 14x7 on my setup. The wood vs plastic at these bigger diameters seems to make more difference: less flex=more useable thrust :)

Not for you Jeff, for the 40 size setup on a slab that was being discussed above on 4s.

Finally got a chance to ring out the bad ass motor today. I’m very happy with it and it drags the mojo 40 around like a rag doll. I was doing 7 minute flights with 3300 4s packs. Could probably go longer. Throttle response was very smooth..

Looks like I’m going to have to give Badass a try. MoJo40’s VH G32 threw a magnet this morning on takeoff, made a god awful noise. It stripped the 4 x-mount bolt threads or backed them out (haven’t checked them yet), and I landed it with the motor hanging below it. What pissed me off more was breaking the prop when it contacted the runway. I bought 2 G15’s for Doug’s slick46, might have been a mistake.

I guess being near 100F today didn’t help. I found another G32 tonight in the motor pile, so the Badboy will have to wait until this one gives up. Trying to save up for a 60” fatty.

I’ll probably back off a bit on the prop in case it’s getting g too hot. Thinking a 13x5 or 14x4.

Some bro’s seem to have great luck with the G32. Personally I have slung magnets on 3 of them now. That’s only on the G32 size. I’ve had outstanding results with the little G force park 400s the last couple years. 3 in use currently with no failures.
