| Hi,
I've spent some time trying to get one running good. Stock exhaust divertor lasted one flight, think I may of expierenced hearing loss after using it.
Drilled the motor and mounted a hatori 90 muffler on it, much quieter. Runs fine but on quick transitions from mid to full throttle back to mid (stall turns) acts like its hanging on the pipe, just makes some weird noises and causes a little vibration. Acts like its running on a pipe, my os61 on a muscle pipe had the exact same problem.
Its smooth in a hover, fff, descents and transitions pretty good as long as its not a quick transition. I also tried a muscle pipe, ran extremely rough on it.
It runs hot which kinda makes me beleive the 90 muffler is'nt large enough for it. Tried quite a few different mufflers, quite a few types of fuel (10%/18%, 10%/20%, 15%/20%, 20%/20%, 20%/24%, 30%/24%), os#8's, enya #3's, gv-1 on and gv-1 off, 9 to 1, 9.3 to 1.
It ran good enough for me to try for a year but the quick transitions are a problem and are going to happen in flight. It may of been happier at the lower ratios (8 to 1, 8.4 to 1) but by then I was tired of messing around!
To sum it up my ys80 (except for the gv-1 thingy, new st2 barrel is installed and will be tried this weekend) and os91 (perfect out of the box) are running great, the jett 76h is going into a plank 
Crunch all you want, they will make more. Please use rr's pm feature to contact me. |
