RE: H9 Showtime 4D electric conversion
Maidened my showtime with electric setup today. Success!!!
It was somewhat gusty today so I did not got the opportunity to really feel how good it flys, but the impression I got so far is that it flies extremely well. Very smooth and precise. At the suggested low rates the roll was fast, but on high-rates the roll-rate is unbelievable. Maybe 5 rolls in a second or so (did not count). I only got time to one flight but I am looking forward to more flights with this bird. And to try the SFG's.
And the sound of it was really sweet. Very, very quiet. The actro is mounted with rubber-mount. But the prop made some strange noise near full throttle on the ground (probably the problem you described Joacim).
The only problem I got was a little short radio-range. With motor at half throttle the range was not very long with the tx-antenna down. Tried to move rx-antenna from inside fuse to outside on top of tail. Helped a bit. Tried to use a rx-batt instead of ubec, helped maybe a tiny bit but not much. Will try another type of receiver tomorrow to see if that one is little less sensitive to electrical noise. Any other suggestions?
BTW Joacim (and any other swedish/norwegian). Are you going to the Arvik meeting this weekend? I'm planning to bring my Showtime there.
Flew about 12 minutes (somewhat careful on the throttle), and the pack charged 1800mAh after the flight. Nice! Pack temperature after flight 25 degrees celsius. Engine temp. 30 degrees celsius.
