RE: Jetti Pro Spin 99

Hi Bill,

Just ran my setup, with the Pletty Advance, Falcon 21.5x13 and TP G8 5000 Prolite+ with 70 cycles on them fully charged. I peaked at 3000W/80A and stabilized out at 2800W/76A. Couldn't get the RPM (too dark) but sounds well over 6k, thinking 6400/6500. This was with the settings I posted the other day.

You should be in that ballpark with the 20.5x14, 6000 rpm is low on any of the new motors/batteries.

PS: Pletty's are 20 pole motors, count the magnets to find the # of poles.

Okay,

Two days of playing with the TX and the Jeti box/spin 99. The best I can get via my ''WATTS UP'' meter is 2640 Watts, 69.2 Amps on fresh Zippy 25C-5000 packs (All four of them). The Jeti box indicates I am turning my APC 20.5x14 at 6040 Rpms (seem's low). I had better numbers with the exact setup in the beginning; 2880 Watts, 74.75 Amps and no idea what the Rpms were. I have no idea what the combination was I used, it was partially Auto set, I do remember that. I figure, I am about 700 Rpms/200 watts short verses what I am hearing from others using the Spin 99 or the Mezon OPTO 95 with the Q80-14XS.

I did discover in the Measuring parameters in the Jeti box that the ''poles'' was set/defaulted to 6 and I changed that to 28 (guessing that is just for accurate measuring). I don't get it...., my Pletty 30-10 EVO has a Jeti 90 Plus and it has scary power! My Hacker A60-7S-V2 with the same prop. and batteries is hitting 2660 Watts and 72.0 Amps Max with a Castle 80 HV.

I am using Chad's set up and it did get better, thanks! I turned the RC On and set the high throttle and tested it, made it Worse. I think I remember what the original combination was, so I think I will try that again. It seems to have plenty of power and it's working way better than the 80 HV did with this motor. The Castle 80 HV works fine on the other two motors, not this one.

I'm out of ideas,..other than better batteries like the new TP G8 25C-5000/5400 packs or maybe F3A Unlimited 35C-5100's? I bet I would get better numbers,...

I just need the weather to cooperate, so I can fly, two weeks of storms already (everyday).....Geeezzzzz.

Anyone have any Cool Power 30% YS fuel or 30% Heli?

Hope to see some of you at the NATS!
