I'm not questioning your decisions but I want a little more data to understand WHY people make the decisions that they do about upgrading. I'm a newbee as far as heli's go but a retired electrical engineer.

1. I put a fuse on the main motor. It makes some sense but I've also read articles that the standard auto fuse is really not fast enough to really protect the ESC. It just sounds logical.

2. Lipo Monitor is also a high priority, potentially helps to save batteries by not discharging them too much. If you switch to brushless this should not be an issue as the brushless esc usually has cut off for your lipos.

3. Please explain the true benefits of dual tail motors. I haven't noticed a problem with my tail yet although as I said I have replaced a tail motor gone bad. Again I've read that the ESC really goes over current limits with the stall current of 2 motors. Yes the motors run cooler but at $6 for the motor and $45-$70 for the controller I think I should protect the ESC.

4. Why the cnc head? under load there is little or no play. I don't understand the benefits here.

5. Are plastic blades more dangerous? I had a run in with my heli when I switched offf the TX before disconnecting the RX battery. I got hit hard but not cut bad. I am switching to flat bottom blades as I'm not ready for inverted flight and I hear that they will increase my flight time. Th only problem I find with the $7/pr wood blades is that they pick up some grass stains at the field.

6. I assume that the landing gear and shaft are much stronger. What's the benefit of the tail fin?

7. I've also had people explain that replacing the rear geared motor with a direct drive helps under certain circumstances.

Thanks in advance,
