You've asked this question about 20 times now!!!

I dont think anyone can help you!

Stop clogging threads up by repeating the same old crap or you'll prob end up banned......AGAIN!

i use a ptfe based lubricant mixed in with bearing oil which takes care of any bearing troubles, a little costly but very good and reduces maintainence quite a lot. bit off topic but how did you get on with the trex 500, i have been learning using an eco 8 and was looking at the trex as a possible upgrade route

hey guys,

i know i'm like a month late on the topic, however i'd be wary of using any aircraft specific motors, both because of the kv ratings (not as significant) but the torque difference, there isn't an extreme need for torque to power planes like the torque used in cars, granted you could test gearing combination and probably work something out eventually but i think i'd stay away from it.

you would be amazed how much torque you need to spin a prop, i used an 8 by 4 prop to run in and get a base setup on my .21's and they do struggle a bit with what would be considered a correct size prop for them, cars require less torque and more revs due to the gearing whereas a prop requires loads of torque and lower revs as most are direct drive.
