New Lehner for my CRT.5

[jnev]

I was actually watching that auction with the Lehner. I just knew that someone form this forum would buy it. It seems people from here buy ever high end BL motor off ebay.

Ha - lol..... I had a feeling other's from here were watching........

Re the gearing: That's good to hear - I e-mailed the guy selling it and he said he was running it in a CRT.5 but it ran hot (around 160-170) with 12, 14 and 16 gearing.

I didn't find out what esc or batteries he was using though - I've found with the MM (and the Mamba25 for that matter) that Low start power and Lowest timing is really the way to go as far as motor heat goes - anything more and things get hot.

I spoke with CC support for a while one day and the guy told me that timing advance on a brushless motor is somewhat irrelevant as any gain made by increasing timing is nothing more than a few percent in speed. The best suggestion was to control speed with gearing and not timing - since I started doing that with the MM and the Mamba25 I have not had really any heat issues with either esc or any motors, unless I am overgearing.

Great buy. I have that exact motor too. I run it in my Lightning stadium 10 on either 3s2p a123 or 4s1p a123. It will be perfect for you on 3s lipos in a CRT.5 A helasiuosly powerfull little motor. I actually reconfigured the sloder on the back of the motor and made it into a 10 turn 1930 and ran it in my 1/8 buggy on 5s for a while. It even ripped in a big truck like that as long as I kept the gearing reasonable.


I love Lehners. They just run and dont ask questions. Let us know how you like it.
