What tires did you use for this run? Car looks fast fast fast!!! nice...Now to get it to stick to the road might be a challenge with all that power.

I actually used the stock treaded tires and wheels that came with the car. I am hoping that this summer (when it is 100+ degrees outside) that the tires will stick better.

ahh, yes heat will help. Those are the saem tires that came on my gtp,,They are ok,,,but I wasn't to happy myself. I'm tryin out the foams on my DM hoping for better results......Was that an actual torque roll at the end of the video?

Yes. Both rolls in the video were due to mashing the throttle. Let me know how the foams work out. Seems like they would wear out fast...but I can see that they will probably stick better.

Guys,

Today I received the top plate from RCPD and does not seem to fit too well. The top plate is from the E-Jammin' kit to the best of knowledge. Now I know I can easily modify the plate to fit but I have some concerns since I also ordered the motor plate. Ofna says the DM-1 Spec drive train is based off the Jammin', correct? Here are some pictures below--let me know what you think.





I really like the plate because you can arrange it to have the ESC close to the front as well .

You should be able to open up each of the four mounting holes just a little bit and you'll be good to go. You will also probably need four 1.5mm spacers (I used the black ones that Ofna sends with their kits for the hinge pins) to raise up that top plate enough to accommodate the 51T spur. Check the spare parts bags that came with your DM-1 Spec...you should see some small black plasitc spacers that will work perfect.

Alright! I received the RCPD motor mount today. The top plate, not surprisingly, fits perfectly onto this mount. I also got the RC-Monster battery tray and will wait to permanently mount it until I get the motor and remainder of the electronics. I hope to balance the car out left to right and front to back the best as I can. If you guys have tips on how to balance weight please let me know. Here are some more pics . . .

Looks sharp! You are going to love driving this car. Did you remove the hard coating from the RCPD parts? Everything that I have ordered from him has a white coating...

I bought some Kyosho slicks myself but have yet to try them but they are very sticky! Kyosho makes them in 3 different durometers--45, 55 and 60 Shore A. I put some on the roller and the car literally sticks to what ever surface I place it on (aside from the carpet!). I think these tires are going to be the best bet for getting these cars to hook-up.
