Default HPI Micro RS-4's

Bought these off Fle-Bay for me and the son to have something to do in-doors when the weather is bad. We are lucky enough to have a great-room that is 30 x 40 with wood floors and all the furniture is on felt-pads and can be slid out of the way easyly.

The blue Nissan Skyline I bought for 73.00 less radio with "Big-Block" motor and Losi ESC.
The Vette was RTR for 83.00 stock.
We cannot make these things hook-up on foam tires. The Nissan on the straights is tottaly un-controllable and acts like you put a 200 H.P shot of NOS to it......The Vette is a little more calmer, but WFO...both are let's say, very loose.........I've back-off the diffs as much as possible.
What tires do we need to get some more grip??? I'd guess some rubber ones???
They are fun tho, on a 6v battery they will run for almost an hour. I cannot imagine what they will do on 7.2.

I have a few also. They rubber tires are best, but impossible to find anymore. If you do find them buy them.

Are you running on carpet?

The micro rs4 is a dying car. Noone really runs them anymore.

Im the guy that ran up the bid on those two cars. Sorry.

Ive got the BMW M3 one. Rubber tires are best for wood or linoleum. Ive only driven mine a hand full of times. Its hard to find a good place for them because of the size.

Had a Micro RS4 over the summer that I bought from a friend. Had high hopes of using it as a drifter, but it was too small and WAY, WAY, WAY too overpowered. My buddy had put a Dynamite C4 9200KV brushless and Mamba 25 in it. You could just barely touch the throttle and it would spin violently...even with throttle turned down to 20% on the radio. If I could have ever gotten it to actually hook up, it would have been a 40-50 mph car.

I agree with seabeejeep, though. The Micro RS4 is a dying platform and parts are becoming almost non-existent. When I first got mine, one of the front axles was shredded (wonder why) and I wanted to upgrade the diffs at the same time. Took me quite a while to find a place that actually had parts in stock.

I tried racing one and once you get it to hook up it sheds the rims off of their hub system.. Keep them as stock or lose as possible.
