I do know that i have run asphalt used tires that did not pick up fuzz the last time I was at the carpet track. I do not know if this will be the same for everyone.
Would any kind of traction compound helps in not picking up the fuzz and yet give good traction on carpet then??

Mine actually rarely bounces (during cornering). It will bounce if i hit a bump going straight (mainly the rear being too stiff). In general though, the car is very drivable and definitely planted.

Try:

1) tightening the disc damper. i run this tighter than stock recommendation.
2) run a red spring. I have the old tamiya red spring, which is softer than current tamiya "red dot" white springs (ie: the kit spring). This is paired to a shock that has 40wt oil and 3 hole piston.
3) lube your kingpings. I put the stock shock oil on the kingpins. smoothed the front right out. The front works exceptionally well... I can see the front arms working over bumps as the tires stay planted.

EDIT: this is all on med traction tarmac.

Jack the Gripper is great for reducing pick up but those Tamiya tires are just a pain no matter what.

I would say go with softer springs first.

The best thing seems to be breaking the tires in on asphalt. Otherwise, maybe try just cleaning with Buggy grip for example. I was able to run paragon at my home track with no issues, but I'm not sure if this was just my track?

I was having some problems with this as well, but with the rubber tires on high grip asphalt. This only appeared as the grip came up. I was not running any type of lube or diff oil on the kingpins, which I normally do for carpet and foam. I have not had that problem with the foams on carpet, which is definitely very high grip, so I assume it is the lack of front dampening. The other thing I wish i had tried was the softer springs, as I think the car was not rolling across the nose enough. It looked like it gripped and hopped over and over since it couldn't articulate. One other fix may be to space up the front of the upper arm to remove some dynamic caster effect. You will loose some mid corner front end grip, but it may help in that situation. These are all things I need to try as well

Hello to all, I'm going to be receiving one of these tomorrow. Was wondering what "functional" hop ups you recommend for the Pro kit.. (I'm not looking for bling hop ups)

Thanks in advance

Aluminum motor mount, aluminum camber plate, low friction suspension balls.

Thanks both.

robk, if you say breaking in the tires on asphalt, i prob try to do with a tire sander with scotbrite to get a more even break in .. you know how asphalts are..

What up fellow F104'ers! Just got my car.

Does anyone have a recommendation for a good lipo battery? Good power but relatively cheap?

I purchased a battery with banana connectors only to find out it would'nt work.

If you get the F-60 top deck it will work as long as the battery fits in the space. The Bannana plugs go towards the back. Thats how I run my car for TCS. Much cheaper then a new battery. As for the Pro top deck I just cut the front back and used 2mm spacers where the top deck met the servo mounts.

Hope this helps
