Turnigy G32 Brushless Outrunner 530kv (.32 Glow)

A G32 should be plenty of motor for your trainer, but you might be better off with the 770kv version... it can run a smaller prop more efficiently. (You may have ground clearance issues with the 14" or larger prop for which the 530kv motor is better suited.) If you haven't already, try the online calculator linked below.

Thanks for the reply, and yes a 14" prop is way too large for this plane. The biggest prop i can fit would be 11". Could you possibly post the SKU for the 770 KV motor you mentioned? thanks again!

The SKU is g32-770. Looks like it is backordered though, like the other G32's.

If you want to measure the actual rpm you are getting then you need a tacho,plenty available on HK website,but in all fairness rpm is almost immaterial,the wattmeter is the most important piece of kit for electric models.

The 13x6 will give 8480rpm/615W/34A.
The 14x4 will give 8590rpm/570W/31A.
A 14x6 will give 8150rpm/674W/43A.
A 14x7 will give 7950rpm/850W/48A.

The motor is 60A capable, so you should use an ESC of at least that size. Depending on use, prop, etc., you might get by with less. I'm flying this motor on a Turnigy Dlux 55-SBEC ESC with no problems - it's a limited run sailplane application. The Dlux 55 is rated for 65 amps in short bursts.

Two awesome equations a learned: mah*c-rating/1000= AMPS OF BAT. (max) Also just in case, for your motor max amps: wattage/voltage=AMPS find the average between these two answers and there is your ESC! :)

Oops...Answer above.

Yes... I used a vice and a couple of pieces of wood to press the shaft through.

All 4 mounting holes are on a 25mm bolt circle.

The 530 Kv motor would be the most powerful as a 5S or 6S Lipo can be used. Bearing in mind the prop size would have to go down. Take a look at Castle Creations web site and there is a prop selection app that is quite comprehensive.

yes u can 14.8v - 14X10 Prop - 34A - 1950g Thrust

well the more power or volts you put on a motor the faster it goes so i think that if you put a 14.8 v on a 530kv motor it will probably bring up to a 7844rpm which will give high air current with 14*10 prop

Same question here!

nivus, i've gotten a couple of replies that say it can be done. The most reasonable one to me is to remove the grub screw and circlip, get a piece of wood thicker than the protruding shavt will be, drill ahole in the wood that is just larger in dia. than the shaft, hold the armature so the shaft will go into the hole, and using a vice, squeeze the wood,armature, and shaft, pressing the shaft into the hole and thus protruding out the opposite end. A small hammer could be used to drive the shaft ilnto the hole if a vice isn't available. Problem is, I don't see a flat spot for the grub screw to seat, so I might remove the shaft entirely as if I were replacing it with a spare before pressing it back in. Also, there isn't a circlip groove on the end, so leave enough protruding touse tehlock coller. I haven't received the motor yet, but as soon s I do, I'll attempt the switch, and report the results on this site.
