20C might be too little for a fairly heavy bird perhaps that's what did them in? My last lot of Flightmax lasted 60 flights (on a B400) before they were delivering noticeably less power towards the end of the pack. At this point I switched them be fixed wing packs where the power demands were lower.

Yes ultimately there has to be a fuse somewhere.

And it is, so far see as, one of the best value for money motor...
We'll go through a good few packs before he gets into a situation where a save with full collective will be required so I might start him with the cheaper motor so he can get a good taste for the hobby without spending a fortune.

Reading the reviews the motor listed doesn't seem lacking in power?

Thanks for the advice clicky.

Inspirational flying Jules. You have that little bird doing exactly what you want it to, smooth and precise. I really enjoyed watching that vid.

On a completely different note.... Your camera man is great "do that again... it was so fast I didn't get it...[pause]...I don't even know what you did....[you do another nice tight loop/flip]..............holy cow look at that."



Take it easy all.
