I say we start with a stock head, change the mixing arms, and
see what happens. Then if it works, we could do all the other
mods (such as balance bar mods and blade trimming) one at
a time to make sure it does not "break" anything.
The stock weights on the F645 are huge.
The blades on both of my 9116's are trimmed, but I have three sets coming from BangGood. That info about the F645 having half of the 9116's pitch is pretty encouraging. Here we go again!
I just came in from flying mine for a VERY short time. The wind is blowing like crazy, but I needed a fix and sent her up against my better judgement anyway.
Once it was up there I wondered if I'd get it back down without breaking something. I did, but it took some doing. I know one thing: there is no way in h--l that a stock 9116 could have been controlled. It would have been bye bye birdie!
