Which Lehner Motor for my E-Revo???
 

I have everything set up to finish my E-Revo. Everything is set except a motor. I have the MM ESC. I have 2 Maxamps 6000 mah 2s2p that will run in serious. I put a thread together in June were enough people said to use the 1940. But I read in the temporary forums were some use a 1950. Which should I buy? And how many turns 7, 8, or 9 should the motor have? I will be manly bashing but some racing locally. I want it fast yet durable and I will mess with gearing after I have the motor. (look for the thread later LOL) I hate to give my business to fine design but I read Mike's temporary thread about not carrying Lehners any more. If any one has a used one they want to part with let me know at cdmiche@sandia.gov.

Also I am using the Emaxx Tranny locked into 2nd. I read a thread from Brian today stating you should have a different slipper clutch. I have the stock one so what other slipper clutch would work? Or work better?

Thanks all!!!

If it were me, I'd look into a Neu 1515/1Y. A good number of folks are getting them to work well with the MM ESC with little to no cogging. I believe Mike himself evens runs a Neu on a MM.

I agree with what skellyo said. As for the slipper, you can try the strobe slipper from the RCM store, or the Robinson Racing one.

I would say a 1940/7 if running 4s. I have not tried a Neu with the MM, but I did try a Pletty (also 4 pole) with the MM. Even the occassional cogging was enough to piss me off. Try FDM, after all he is THE US distibutor for Lehner now. I know many on here have bad things to say about him, but I have had fantastic service with him.

What is cogging exactly?

It is like a hesitation until the ESC finds the rotor position. It can sometimes cause a violent jerking if putting alot of throttle into it from a stand still (very bad).

I am a perfectionist. I had to buy a new radio because the stock one I had for my BL Stampede was jerking around the truck. I don't understand it but the ground was harder than the radio. LOL I don't want cogging to happen so I will stick with Lehner. I am not satified with the reports of the customer service from Lehner but its what I run in my other RC's. They work great for me. I hope Fine Design works out.

As a side note whats the difference between a 7 turn, 8 turn, or 9 turn motor? Say the motor is a 1940.

Lower number equals lower wind. Lower wind means faster motor. Look at the kv number which is rpm per volt. You want to run your motor at a max of 35k rpms. This helps keep the heat down. Multiply the voltage battery you wish to use by the kv to get a motor rpm figure and try to stay below 35k rpm. Such as 14.8v x 2200kv = 32500 rpm = good. And then gear your truck to the speed you will want to run at. I gear all of my stuff to around 40mph cause it suits my drving style and area I play in.

I am looking new motor too, but I dont know what I take.. Is Lehner 22XX good motors ? I am looking good speed and torgue for my revo, I use 10 000mAh maxamps 7.4v LiPos (14.8v) . Some peoples says Neu 1515 1y, but its out of stock and I need my motor soon.

Get a lehner 2230-2250 and hit 60 in that revo. You might have to run more voltage.

As in 60 MPH!?! That fast?

I have a 1950/7 turn I may part with. I am also in Southern Utah (Washington) so you won't have to pay shipping! Or if you just want to bash, let me know.

I am interested. Write me at cdmiche@sandia.gov. We can go from there.

Ive read about people with this 22?? on 4-8s hitting 60 np. Just search lehner 2230, 2240, and 2250. O and there the same price as a 1950. But I dont know how well the revo will handle at those speeds.

My lehner 1950/6 is great on 4s in a 8.5 pound truck, before that it was a 1940/5 on 3s it rocked too.
