Hi,
first time poster here
.
Small Intro (feel free to Skip):
I startet RC flying after I stumbled on the Flite Test Beginner series in YouTube. I decided that I want to build from Scratch. After flying for some time the FT Flyer I built the FT Delta to learn to yank and bank. Then I had the worst crash so far, which broke my prop and bent the shaft. I fixed the shaft but I had to order a new Prop. The first three flights went very smooth.
But now to the reason why I am writing this:
Sometimes when I throttle up with the new prop, above 60 % or so, it just cuts the throttle. I don't think it's the ESC because it makes this weird grinding noise while doing so. Then I have to throttle all the way back to 0 %, and then back up and the motor turns again. When I let it rest some time, sometimes I can use full throttle two to three times before it does it again, and from then on it is everytime. Without prop the Motor turns just fine, even at full throttle. I filmed a quick video in which you can see the problem.
My set up is the following:
Prop:
8x4E Slow-Fly
Motor & ESC bought together
Motor:
Robbe Roxxy-Outrunner 28-12
1720 kv
6,2 A; 7-9 V (2S LiPo)
ESC:
10 A (max. 12A for 10s)
LiPo:
2S 450 mAh 30C
I hope you can help me, if I forgot some needed specs I will happily add them on request.
Thanks in advance,
Logarn
