Wow, that's awesome! It's amazing to see something that big do donuts like a 10th scale.

Great work.

That's it! show that screamer who's boss Jeff... Nice work..!

Thanks guys.

Its straight line fast for sure, but I will find out if it handels worth a turd on Friday. Really looking forward to it.

He has something exactly like that. I know for sure.

Thats good news because I was thinking of getting one of the KB45 motors. Anyone know if the endbells or pressed or not? I might see about getting Mike to make a heatsink/clamp for one...

I admit it - I have a 2230 on my 8t at the moment - made an adapter for the task. :)

What exactly is this adapter? I don't really understand what it does, or what it even looks like... Do you need it if you run a Lehner? Do you need it for other motors as well?

This adapter will allow you to fit a motor without a 25mm screw pattern (25mm = distance between mounting holes on a 540 motor) to a mount that has a 25mm screw pattern. The KB45 motor has a 30mm screw pattern and uses 4mm screws, so an adapater for the KB45 would allow it to mount up to, let's say an E-Maxx motor mount that uses a 25mm screw pattern and 3mm screws.

squee, the KB45 motors have screwed-on endbells. I talked to a guy who said his unscrewed very easily (so he took measures to keep it tight), but my KB45 10XL will not let its front endbell come loose. I've tried a grip wrench (rubber strap wrench) and a plate held in the vice attached to the front endbell by 4 screws, and I would've broken the grip wrench if I were to have used any more strength.

thanks for reminding me why i hate nitro cars all that noise and no go worth a toss.
I could see you were struggling with the brakes in the video as you mentioned i wonder why the stock brakes are so naff is the car heavier than nitro form?

Also what servo are you using for brakes perhaps you need one that has more torque.

The brake servo is an airtronics 94758 digital (115oz) so it should have plenty of torque. When the brakes are cool and fresh it can lock the tires up easily, but after only a couple hard stops they heat up and fade to the point of being useless. They get so hot when I picked it up to check what was going on I could smell them burning.

The car is ever so slightly heavier than the the nitro form. But not much at all. The guy whos body I was borrowing runs his DM-1 nitro and we were comparing the weight of the 2 by holding one in each hand. We concluded that my electric was heavier, but it was so slight it was very difficult to tell by comparison. Couldn't be more than a few ounces different. He has the same problem with brake fade on his also so I think its just a function of trying to have a single disk do all of the work to stop that thing. Buggies have 2 disks and truggies typically have 4. This probably weighs about the same as a typical buggy. I think if I upgrade to a 2 disk setup I should be OK.

Mike,

I have 3 22 Series Lehners (2 2240 and 1 2250). I would like to buy 3 adapters if you have them available.

Thanks Metalman. I'm really thinking of getting one of these for my BPP LSP. Only thing is, I don't know if it will fit between the braces. I know a XL will...How much bigger than a XL is it? Diameter wise.

Feigao XLs are 36mm in diameter, KB45s are 45mm in diameter. So figure 9mm, or 1cm or 1/2" for clearance.

I had to cut a peice of the brace out. Even the Neu 15 sereis finned can't fit . I'll take some pictures leter today to show you how close the fit is.

any updates on this, jeff? i'm watching this thread eagerly... i'm not a on road car guy, but my LHS does have an indoor track...although i don't think it's 1/8 scale. but it'd be fun to practice there! :yes: your car is just plain wicked...

any more vids or updates on the car.....that is one sweet Ofna DM-1:yes:

hey where did you get that lehner?

OK reeeeeeally overdue update.

Its finished and I did get it out for a couple evenings of parking lot oval racing before the weather got way to cold. It was still cold out so the tires werent holding the pavement that well. the most fun part was the speed runs. Its a huge lot where we race so I was able to really open it up. I had my 1/8 buggy up to 60mph and this thing was way faster. no radar or GPS yet, but I'll get GPS onit in the spring. It was so fast I was almost afraid to totally open it up. I dont think I really ever got it to top speed. I'll wait untill sping and warmer temps so the tires have better grip. As for the oval racing its almost to fast. I had a hard time keeping the back end in line with the cold temps and poor tire grip. I let it get out of line the first night I had it out and wound up clipping a concrete pole at 30-35 mph. It really sucked. Turned out all the broke was the rear hub carier and I bent the rear CVD and blew out one rear bearing. I was able to straighten the bone and the rest was thankfully only a $11 fix with shipping.

Fixed it and had it one more time on a relatively nice night (40 degress F :whistle:) This time I got a chance to put some laps in and I gotta say I think I really like it. It absolutely ripps. It takes a lot of thottle controll and take a very diferent driving style to get it around the corners quickly, but once I got the hang of it I had it really turning some fast laps. Nobody was keeping up. :na: I really liked the 2 speed. On the straight, it was like a little turbo boost kicking in and it just lurched when it hit 2nd gear. Once spring hits I'll start working on tuning the suspension to get it right and dial it in. Is still box stock setup and I'm sure it will be able to be tuned for much more consistant performance.

Anyway... nobody really want to read all this blather. Here are the finished pictures. Sorry no more vid. I broke it the first time I brought it out and didnt get any, and then forgot the camera the other time.

Ebay

:surprised: wow! lehner 1950! on ebay! wow! :lol:

any new updates? vids?:smile:

Its snowing and cold as hell here now. So no vid till spring. I will get some then, but it will be a few months which really sucks cuz I hate having this nice new toy and not being able to play!:grrrrrr:

jUst wanted to know, how much were your electronics, I want to really get my project DM-1 started someday soon.... besides the electronics, what else did you have to modify or buy from RC monster?

thanks a whole bunch for the excitment!:party::yes::party::yes:

Did you ever figure out anything for the brakes? I want one of these things, bad. I would want to do an hv setup, probably on an airplane controller, so I would run the mechanical brakes. You can just double them up, correct? Or if you swap to the center diff, you could use the buggy brake setup. Ill probably end up using a center diff and doubled up front discs with a single rear.

The speed control is available here at RCM for about $275 and the motor was aorund $325. You dont have to use that high end of equipment to make one go though. The Mamba Monster Max or Tekin 1/8 controller/motor setups will likely be cheaper than that and should be a great fit when they are released (soon hopefully). Even a Mamba Max and Feigao on 4s would work. The car is no heavier than a 1/8 buggy and they work fine in that application.

The only other thing I bought was the Jammin Buggy motor mount from RCM. The rest of the stuff I made myself.


Any of the solutions you mentioned should work fine for solving the brake fade issue I ran into. I got a pair of fibergalss disks to replace the singel steel disk. I haven't been able to test it yet due to the winter weather, but expect it should do the job as well.

Cold as where???

There's one in every crowd....:whistle:

hey its getting warmer....any updates?:yes::smile:

Yea it getting there now. I will probably be a couple more weks before I get it out running again. Still cold at night and I generally do most of my on road running on friday nights in store parking lots atfer closing so there arent any cars around. Need some decent evening temps before I head out there for the spring. But hopefully soon!

sorry to ask again....updates?:yes::smile:

Mamba Monster Max.....
 

hello again, I wanted to know, How will the new Mamba Max Monster with 6s Lipo's do on this car....being using everything stock like up above?


this car looks like a fun project maybe in a couple months......

No. Nothing yet. It keeps raining on Friday Nights when I would normally run this thing. Soon....


Yea. The Monster Max would be a killer esc for this. I gotta say though 6s would be nuts on this car. Its nuts on 5s I can imagine adding more power.

Go for it. Its a great poject.

What kind of speeds are you building this setup for??

the speed i like would be just like the vid shown her:smile:e......:yes::yes::smile:

Thats set up for right about 60mph. Plenty for general bashing. You could easily gear it higher for speed runs.

Far out that is nice. Everything is clean and looks factory, Top Job

arrrrggghhhh No updates, vids yet? arrrrgghhhhh ;-)

wow,,,,no updates or vids yet??????? its summer!!!! (LOL)

:lol:Dude!!!! You are relentless.

I have run it a couple times, and tried to get vid once, but it doesn't really get anything cuz its to dark out in the lot where we run. Thats why I painted it yellow. SO I could see it in the dark lot at night.

As for updates. What is there to say besides what I said already. It runs nice. Very fast. Actually to fast, but in a good way. About the time I start to outrun the nitros it kicks into 2nd gear and its like nitrous oxide and its just gone. The last time I had it out there I had 2 guys laughing at it cuz it was so fast they thought it ridiculous. Another one of them was telling me that it was no good cuz I would spin the tires to easy, and then I lapped him and I didn't hear any more.

Its loads of fun, but I haven't been able to run it as much as I would like. I have been spending most of my RC time at the track with my buggy and truggy.

Build one, they are fun. I'll try to get some vid next time I take it out.
