Also... LMK what gears you need, Brian. I can easily make an 18 tooth mod1 pinion in 1/8" bore if that is what you need. :)

That pitch chart and explanation is great! Thanks.

So Mike, when you say "Lehner", which do you mean? The basics or the LMTs? Yeah, I don't like to use any motor with exposed insides - too much risk of getting crap inside.

Mike, I thought all the Wanderers have 5mm shafts??

I was referring to the "19" series motors, Brian. The basic series is a step above the wanderer/Feigaos, but 2 steps below the "19" series in terms of real world efficiency in a car/truck application.
Squee...I get the "s" wanderers with a 1/8" shaft - 5mm doesn't make sense in the small vehicles these are likely to work well in, as gear selection would be a giant PITA. :)

Hmm. I was afraid of that. I'm sure those 19 series motors are very nice, but man are they expensive! Seems almost a shame to use one in a Jato.

For the sake of argument; based on the fact I'm using this motor on a Jato (~4 lbs fully loaded), using 3s E-Moli Li cells, what is a good turn motor to get? I want speed (about 3100 rpm/v), but I also need to be careful about current draw since the e-moli cells are only good for 10-15c tops. Maybe a 1920/9? Also, I just noticed you don't even have 1920's.

I DO like the fact that they are efficient and stay cool though, and are lighter.

I have a jato in the making as well. I going to try it with a couple different motors. I am leaning to a 4s lipo oand a 12s feigao. I have esc and motor already. I have a 8s as well. I may try a 380xl in it to. I can give you my report on it.

Yes, please do.

By the way, how are you laying out your components? I didn't like the plastic thing covering the majority of the front end so I made a new upper deck out of 1/16" 6061 Aluminum, which is meant to hold the Rx, steering servo, and ESC. The motor is in the back (obviously), and the batteries just in front of the motor. I still have to make the motor mount, but I think I have what I want to do in mind (thanks to the help here). After calculating the weights of the various parts, the truck should be right around 3.5 lbs (and that's being generous).

WEll I got mine from joe. He had it converted already. I just got to do a little here there and see if it helps or hurts. I have not totally decided yet on everything. The stock plastic plate has been hacked down some on mine. It is light and strong still. I let you know. I am still running a two speed trans with manuel brakes. :D I have a need for speed.

Sorry, Brian. I have a few 1920 motors here, but forgot to activate the listing! No wonder they haven't been selling! :)

I hacked up my plastic part as well until I decided it just wasn't right for me - only about an hour of wasted effort. :rolleyes: As far as two speed tranny, that was the first thing I removed. You'd be surprised, it saves quite a bit of weight. Plus, I wanted reverse. The single speed ratio falls pretty much right in the middle of what the first and second gear ratio was. I figure I can make up the speed with gearing and/or a faster motor. Do you have any pictures? I won't steal any ideas, honest. Just curious how things are laid out and what a BL motor looks like in there. :) What did Joe (is he a forum member?) use for the motor mount? I plan on using some 3-4mm thick angle 6061 aluminum.

Well, don't list them until I get one! :027: How much are they, or are you going to list them?

EDIT: Nevermind, I see you listed them... I take it you don't have any 9T? The 7T will probably suck too much current... If you don't have them, can you get them in a reasonable amount of time?

Joe would be me :003:

You can see the evolution of my Jato conversion at http://www.rc-monster.com/forum/showthread.php?t=957
The V3 with the motor mount on the tranny is what I sent to Leroy (coolhandcountry).
It's a little bit of a read, but if you get through the whole thread you'll see all of the things I did to make it the way it was.

Hope that helps!

Don't forget, Brian...the Lehner motors are kind of "2 in 1". The 6 turn can be reconfigured into the same Kv as a 10 turn. The 7 turn can be reconfigured into the same Kv as a 12 turn. They kind of serve dual purpose in this respect.
By the way...Joe is Batfish on the forums. :)

Whoops. Didn't see your post, Joe. :)

Thanks "Joe". :) I read some of that thread and I didn't see where it said why the motor mount on the chassis didn't work. I would think the mount on the tranny would be far weaker, but I wouldn't dream of second-guessing someone who went through 3 versions of a Jato! :) Did that Lehner Basic 4200 get hot? Any idea how much amperage the motor drew on average and pulse? I wanted to see the videos you had, but the they were removed or something. :(

Mike: Yeah, I forgot about that. I now remember reading something about that somewhere but I never really understood it. I know you are basically changing the windings from delta to wye configuration, but I didn't get the calculations for the kv/amperage ratings for each configuration. IIRC, the document was translated or something and it wasn't too clear.

EDIT Oh, do the LMT have the same efficiency limit of 40k that the Wanderers do? How amount the Lehner basics?
