Ofna DM-ONE electric conversion

[TrevvyD]

Hi guys, I,m pretty much in need of some real help here, I,ve bought myself a Ofna DM-ONE kit which is motor-less ect. I thought, for a good excercise I,d go electric with this one. Now this is where I need the help. What is the best setup. I,ve seen the other DM-ONE here on the forums but cant find that particular motor anywhere but at the makers web site and they havent got back to me.(and some of the instructions for emailing them are in French I think). Searching the internet has opened my eyes in regards to how many electric motors ect are available, all saying there the best,,, bit like nitro engine manufacturers I suppose. Anyway, can someone point me in the right direction, I,m using a Kyosho GT Inferno at the moment and would like to have the Ofna close to that in speed ect, is that posible, oh,, we only car park bash these things as no tracks here in Perth WA are aloud to run nitro cars ect.
Now the second question may sound a little lame but here goes, Can I use my 2.4G controler with the electric set up.
Regards Trevor

Many people here are running 2.4 Ghz radios with their electric vehicles. Including me.

It seems this ofna is a pretty big on road car. I think your biggest problem is going to be getting a motor mount.

You may have to e-mail mike (RC-Monster owner) and see if he can make a mount.

You did not specify how much money you were willing to spend. But you could get a NEU 1521 series motor to push that car around. Even a 1515 series would push it around pretty good. There are many people pushing around heavy 13-15 pound all aluminum savage trucks with a 1515 series NEU motor.

A MGM 22418 ESC would be good:

Actually, the motor mount for the DM1 is no problem at all. The Ofna CR (Jammin) buggy mount is a direct drop in from the RC-Monster store. Here. DM1 uses the same diff mount as the Jammin buggy so no mods are even needed to make it work. The only real challenge on the DM1 was figuring out how to mount the mechanical brake servo if you want to keep the 2 speed in it. I did keep the 2 speed and I really like the way it drives. I have been itching for spring to get it out and run it again. Here is a link to my DM1 conversion thread..

Ive actually got a engine mount on its way to me as we speak,,, I just wasnt sure what motor and ESC to use. thats where I,m wanting to rely on you,se people experience.

Thats the conversion i,ve been pouring over for days now,,,, mechanically I,ll take on any task,,, I just need to know where to get the motors and esc from and what size.

I would say batteries are really your starting point - Are you looking for 4/5/6s Lipos - do you have any now?

Once you have that worked out you can determine your motor KV and ESC to use. It may be a little much (power wise) but a neu 1515 2.5D 1700kv seems to a nice choice - Bigger than a normal buggy motor but this will be a high speed car.

In terms of ESC for 4S (maybe 5s) a MM with a a few mods works great or wait only a couple of weeks and pick up a Mamba Monster.

I,ve got to of these here some where,,, new, unused,(TRAKPOWER 5350 2S )
Would they do the trick.
I,ve ordered and paid for one of these (Lehner 1950 - 7)
How am I going so far,
Thanx

The trak powers will do nicely if you set them up and run them in series as 4s.

ANy of the setups that people around here are running for the Monster trucks and truggies will do just fine on the DM1. Neu motor would be great, but a Feigao would work ok too. The Feigao would run hotter though. As for the esc, the Quark is working fine for me, but the Mamba Monster is due out soon and it would be another great choice, as would any of the other large scale ESCs, MGM, Quark, Mamba Max (up to 4s), even a BK Warrior would work fine or any of the other million off brand ESCs out there.

the DM1 is oretty much just a long bugy with revo style shocks and short a-arms. Anything that works in the buggies and truggies would be fine in the DM1.

That lehner is 1791kv on 4s that will be 26506.8 RPM - Should be ok but more of a 6S motor I think. It is a two pole and with only 4s a Mamba Max with an UBEC and extra cap you should be fine. (I recommend the Novak 2700uf HV cap).
