Ofna DM-One Brushless Conversion (DM-1)

[ssspconcepts]

Well, I worked on it most of the day and this is how far I got. I swapped the 2-speed for a center diff and swapped the stock diffs for spiders.

Hopefully the motor will be here Monday.

Man that thing is a beauty--if I have not said that already. Are you using RCPD motor mount? I like how they suspend the ESC. Will that battery tray fit a 4S?

I have ordered a few things for mine but have to wait to X-Mas to start the build .

That is a rc-monster motor mount. And that battery tray will definitely fit a 4s pack with ease.

Awesome build! Looks really clean. What motor do you plan to run in it? What voltage?

Too bad there aren't torsen diffs that can hold up to BL power...

Thanks. I used RC-Monster Mike's Jammin CR X-1 buggy mount and RC Product Designs' Losi 8 diff top plate (required some dremel/drilling to get it to fit), and a RC Product Designs Losi 8 battery tray. The battery tray will fit up to 6S flight power/thunder power packs. Got a Castle Neu 2200kv motor on the way.

Thanks. I will run the Castle Neu 2200kv at 5S.

Nice. I will probably go with the Novak conversion kit but I really like the idea using the RCPD top diff plate. Puts the ESC out of the way and makes room for battery tray. I can not wait to do my build. I was thinking of using Novak's HV 4.5 but believe that motor is 5000Kv and may get a little hot in the old parking lot. I was hoping for a +60mph car .

If you run a similiar setup like what SSSP is planning, that speed can be done!

5S with a 2200kv Neu can easily be geared for 60+ mph...especially with this rig because it is very light and it will be a road car.

The EL8 RCPD top plate is nice but I recommend you get the one for the Jammin because I had to drill out the mounting holes quite a bit before everything would line up perfectly. I finished the mount by using some flanged spacers/washers so it would look nice and tidy.

Should be pretty similar. I have a Neu for my Losi 8ight but have Novak in my HPI Superten--the thing is a land rocket and is in the 65+mph range.

I just read the Novak recommends their HV 4.5 for speed runs only. I think they are referring to use in an E-Revo or something like a monster truck.

I will gear down the pinion and use a 4S--hopefully I will not melt anything. I would love it if this thing could squeal the tires .

I bought the Kyosho F430GT body and am going to paint it like this yellow Scuderia:

Gotcha. I will pick up the top plate for the Jammin' buggy. How light is the car compared to a 1/8th buggy? Also, it seems that you knew to upgrade the diffs--will the stock ones not hold up very long under BL?

The stock diffs were plenty robust...I had a spare set of the spiders. I figured I'd use the spiders since I had them handy and they are smoother than the stockers. Not exactly sure, but the car is probably 10-15% lighter than the Jammin buggy-IMO. It is considerably lighter than my BL Jammin CRT, which is set up with the same conversion stuff.

Are these the Spiders you are using?

Not exactly cheap! I think I can find them on eBay for a bit less. Not sure but will probably run the stock ones in the F/R but replace the center diff with a Spider. You mentioned there was a fit issue or is it a direct fit?

Those are the ones. If you drop in a center diff, you will have to replace your rear center drive shaft with a different size...I have a spare if you need it.

Thanks! I will let you know once I actually get down to it. I am wondering about that solid center shaft that another member posted the link on Tower or the Spider center diff. Is there an advantage to using a true differential over a solid shaft?
