Hi.
I posted this message at the Walkera forum as well, but since it is somewhat general, I thought I could find some interesting answers here as well.
I am new to micro helicopters. I have only flown big nitro birds and some .30 nitro machines. I just got a dragonfly 60 micro, and am waiting for hobby-lobby's falcon 3d. However, I couldn't find a reference for an initial setup for the heli, and have a few questions (actually, after bulding and flying quite a few helicopters, I was surprised that someone would sell a helicopter without this information):
1. If there is an advanced flyer who is flying the dragonfly 60, I would love to get a good setup. I run it with walkera's 180 motor and 20A ESC. I would love to know pinion setting, size of blades, and pitch settings for normal and aerobatic flights. Also, I would like a good throws setup for the flybar paddles. This would be the best for me to start with.
2. It seems like mini electric run a much higher head RPM than nitro machines. What RPM should I generally aim at? The heli came stock with a brushed motor which is practically useless, but still head RPM was quite high (very unlike my x-cell gasser, with it's low RPM and giant torque). I could not tell by hearing if this was right, but the heli was stable (and without noticable vibrations) When I put the brushless motor on, RPM has increased even further. Somehow it does not seem right. My intuition says to put larger blades, to keep the head RPM as before. It must also be related to power consumtion and flight time. Last, I realize these motors get hot during flight. I guess setting the right RPM should consider that as well. Any thoughts about that?
3. Are there "governors" for the electric motors to keep constant RPM, or should I stick to throttle/pitch mixing? (I have a futaba 8UAH. It's old, but still a perfect tansmitter, so all the mixers are there.)
I know it's all newbies questions, but that's what these forums are here for right...?
Thanks,
Avi.
