vids yet? :smi le:

Where do you guy's find this wire loom?



Thanks

I just threw away a bunch of that stuff last week! Figures.

RadioShack has it. I prefer the split loom more though because the stuff in the above pic needs to wrap around the wire over and over. Kind of a PITA if you need to re-wire or work on something.

thanks for the vid

wow, that parking lot seems too small for that fast Brushless 1/7 scale you got there...... amazing......amazing-ly fast.

Swear it tried to wheelie a few times in that vid, awesome work.

Second that... I saw the front end lifting and almost said, "Downforce, do your worst!"

Ofna just released a DM-1 "spec" car! its suppose to have a shorter wheelBase for racing. and two speed transmission.

The DM-1S is the shorter version of the DM-1 Series. It is designed for competition in spec class racing.

Hey all,

I just ordered a DM-1 Spec and some other stuff to begin my build. I am planning to use a MMM, Neu 1515 1Y, and 5S or 4S FP 5000mah. I am looking for recommendations on the following aspects of the build:

1) Should I use the stock 2-speed, 1 speed spool, or center differential? I have a spare set of front/rear/center spider 8 diffs and I am considering using these. What do you think?

2) What gearing do you recommend?

3) What weight diff and shock fluid?

4) Any other misc. recommendations or lessons learned from other BL on-road builders?

I will be out of town for a couple of weeks but will post many pics when I return.

Thanks for taking the time to read and reply.

Definately go single speed! Brushless and 2 speeds do not work to well IMO. The car becomes too uncontrolable and not fun! The easiest thing would be to run the center diff, but JB weld it to make it a solid and you can the Kyosho plastic gears.

2) What gearing do you recommend?
All depends what speed you want...

3) What weight diff and shock fluid?
Again, depends on what you want to do with the car...

4) Any other misc. recommendations or lessons learned from other BL on-road builders?
HAVE FUN!!!!

That is what I would do.....

Greetings,

I have been searching the internet for anyone else converting the OFNA DM-1 Spec to brushless. I am planning to do the same this winter! Apparently the drive train is the same configuration as the Jammin' X1 buggy so immediately I thought of Novak's conversion kit. The problem I was wondering was the same as your question #1. What to use for a center diff?

I figured I would use a single-speed and did not know if there was a choice between a solid and a spool. I know OFNA manufactures a single-speed solid diff I believe they use in the Ultra GTP kit setup for dirt oval.

I would love to see pics of your conversion and will subscribe to this thread. I use a Neu 1512 2D and the MMM v3 in a Losi 8ight conversion but was thinking of using the Novak HV 4.5 in the DM-1 spec.

What are your thoughts on the battery tray? I am wondering if I will need to fabricate one or retro-fit the RCPD tray or use the Novak's somehow. The chassis is narrow on the DM-1 and would like to balance everything as best as possible. Cheers!

Just got a lot of my parts for my DM-1 Spec BL project.

Man, you are so lucky--she is a beauty. How did you choose the spider diffs and will they fit Kyosho spurs?

Yes, there is a single-speed (and two-speed) center "diff" option for the Ultra GTP. The 51T plastic gear attaches to an adaptor plate, and that is secured to the shaft via a 5mm set screw (there is a flat spot o the shaft). Pretty simple and light. Since it uses 51T spurs, so you have to make sure you have enough chassis clearance because of the larger diameter. The bearings for it are different than most true center diff options, but not exactly sure of the exact size off the top of my head.

BTW: The single speed holds up very well to BL power. I've ran a few packs through it and everything is working fine.
