Default Re: Planning e-conversion for 33% extra

Well my ESC died on the ground... a shame but I think there was an inherent problem of some sort, as I was monitoring the voltage and current closely on running up a hotter motor for the first time. (180kv instead of 130kv).

At 42v and 70 amps the magic smoke came out of the K Force 120A controller... closely followed by the magic bloody great flames - fortunately everything survived, except the paint on my cowl which bubbled from the momentary heat!

I've been happy with the HXT motor, but having seen the new version Hobbycity are selling I'm going to be much more comfortable throwing the plane around. It looks the same, but really isn't. Huge great rear bearing, no more reliance on a tiny retaining circlip and even a standard gas style prop adapter to get away from torquing against the bearings when fitting your prop. The windings are nice and tight and well done too, where some of the old ones were very lazily produced.

HC are now also selling an ESC that truly opens up the potential of the motor: 200 A HV esc It seems to come from a respectable manufacturer too.

I might yet get close to the crazy vertical that I get with my 27% / Hacker A60 setup.
