Gday Ingo
Glad to hear all went well for you, the twins do sound quite angry don't they.
I was a bit concerned though when you stated that one engine fired up whilst the other failed to kick in. I had that issue when I was initially setting up my Twinstar and traced it to a difference in voltage drop across my throttle y lead. I ended up going through a pack of y leads until one worked perfectly and the problem resolved itself. If your problem persists you may need to make a mental note to always keep a little bit of power on until your are solidly back on terra firma. The concern is that you chop the throttle on finals and then may need to go around however only one engine sparks up thus leaving you in a nasty asymmetric config. I have also read on some forums that some fliers have had success changing their motor timing to ensure both motors spin up concurrently every time. This seems to have no real rhyme or reason and differs from motor to motor/ esc combo.
Look forward to having a "twin off" with you when I have my one sorted, I am in the process of rewiring with heavier gauge silicon wire due to all the existing wiring getting very hot during ground runs.
FYI I am running Turning 35/36 1400kv motors, 2 Plush 60A esc's with BEC disabled, 9*7 3 blade props powered by 2*3S 2650 Nanotech batteries one to each motor/ esc. From memory pulling just shy of 50 amps per motor.
Sounds insane flat chat.
Cheers
