So I continue to have stuttering issues. I tried low acceleration, high timing. I re-soldered everything. I direct soldered instead of bullets. All to no avail. I decided to try different props. With a 15x6 I don't get stuttering, but obviously the numbers are in a different range. Here are my numbers on a 5s, 25c 3300 mah battery at full charge.

Motor: hacker 40-14s, hacker 70 esc

WOT
15x8: 65 amps, 1170watts, hot motor
15x6: 55 amps, 1020 watts

as the battery drains though I get these numbers

15x8: 60 amps, 1030 watts
15x6: 49 amps, 900 watts

Stuttering issues become less frequent or go away altogether on 15x8 as the battery is drained.

I feel like the 15x8 is more in the preferred range at WOT. Either way I can't get it to reliably work. This is getting really frustrating. I'm hoping I can just bring everything to the AMA show in a few weeks and have aero-model look at it. Otherwise, I'm gonna start trying a castle lite.

I've tried all the different combinations of acceleration and timing. Changing PWM had no effect. I can program around the issue if I use activation delay on the throttle curve, but I have to put it really high to the point where it takes a few seconds to get to full throttle or power down. That's just not going to work when I'm landing. Tried messing with my throttle curve, didn't seem to have much effect

Just a guess, but probably buy skis, see what is needed to modify and/or mount them, perform said modifications/mounting and fly

axle is the stock axle.....the wire has a 90 degree bend in it where it goes through the front of the ski to hold it against the collar....collars on both sides of the strut....the factory springs that come with the skis dont work in this application
