chris_kline said:well looking at the alien power system 83100. that actually is the chinese motor i had.
chris_kline said:no, my battery pack is rated at 160A cont. but my old motor was drawing 160A peak when full throttle on the jetdrive.
i dont really expect that to change much, since im using the same size prop, and the motor will have the same number of windings
srn said:Thanks you for this information.
MGM + Lehner would also be my first choice at the moment.
I am currently milling the drive unit foundation. Will post pictures in the next days.
chris_kline said:no probs, yeah post it up when done, would like to see it.
i also called scorpian motors, and they gave me an offer on this https://www.scorpionsystem.com/catalog/helicopter/motors_4/hk-70/HK_7050_340/ of with water cooling, at custom 250kv of 1100 USD shipped.
madin88 said:Maybe the 80xx series from Neumotor suit your needs. It has 80mm stator dia (100mm outside), available up to 57mm in length.
It should be a torque monster, but the max rated RPM is 8000.
These motors have thin 0,2mm lams!

at the moment i build a middrive with one:

I created completely new jet. It will be availible soon for download, after I printed and testrun it. Here are some pictures. I improved bearings, added grease nipples, better waterflow..........

lehner motor. looks nothing like it does in the photo. looks well engineered, its smaller than i expected, some real nice innovations in it. like each winding solders to a pcb instead of being wound to the next winding (ill take a photo so you understand what im trying to say). The thing i was suprised by though, is there was not as much copper as i expected on the windings, im kinda dubious its going to live up to expectations.
if it doesnt, i think im going to design my own motor

Hello Chris,
how about your progress ? Is the Lehner running well with the MGM ?
chris_kline said:hello
i didnt recveive the esc yet. mgm said it would take 3 weeks to complete, but it then took nearly 2 weeks just to get an order confirmed from them, ultra slow response via email. its now been 5 weeks since i started the process
feeling a bit frustrated
