Why else would TC3 team drivers be using aluminum drive shafts, other than the carbon shafts breaking?
You may be correct but the main reason the TC3 guys run the aluminum shafts is because they run a lot more true than the carbons. A slight wabble in the shaft and you loose a ton of efficiency. This is to go without saying that the carbons had a tendency to break due to flex.

Proteus, did you hook a brotha up???

David Joor, wish you could have ran the HPI at the Nats, I really needed setup help. That BMI chassis looked like the way to go, do you know how we can go about getting one???

I have no choice but to worry about my buddies cars. When they don't finish the race that we're in I ask what happened. I was going to try the Pro4 myself before the Schumacher deal but there's nothing that I can do about that now. Good luck to you and I'm sure that BIGDOG will be fine so long as he doesn't hit the boards....

...speaking of boards what type of barriers are most people racing with? Our outdoor track has boards which will seperate the men from the boys. Some guys race or tracks that have burms like the Tamiya track. This may also be the reason why some have had problems and others haven't.

David - true that! But I didn't want to comment on the nature of the carbon HPI shaft (whether it is out of true or not) before I saw one

The Teacher - I already have a great setup posted for the Pro4 on carpet for club racing traction levels. If you haven't been to a national carpet race in mod, than you must understand that a great setup for a club level race is about 50% right when you get to a national level traction track. The car will get on two wheels every turn or spin out. Just requires some tweaks here and there.

Frank - your a funny man! I have no doubts in the trueness of an HPI product.

Board tracks have more traction than the concrete tracks (cleveland and snowbirds are board tracks), but they still don't generate the amount of traction on a local level. Mainly it is from the few hundred cars running on the carpet all day with a ton of paragon. It would be like getting a sprayer filled with paragon and spraying the track down with it

BTW - Stock is not nearly as affected as mod.

David Joor-Good to meet you this weekend. Glad your home safe and sound. The only problem with building board tracks right now is lumber prices are through the roof. Price out what it costs to lay down a wood subfloor-then add labor to install it.......


But-no doubt-a board track has mad grip-even for a club race compared to one layed down on concrete.

Talk to ya soon,
Ray

Default new parts posted by Proteus, abroad

Those aluminum shock bushing will definitely help! The stock plastic ones, deform a little too easy. I'm definitely gonna get that graphite main drive shaft - its DA'... HEAT!!

David and others, can you suggest a spare parts list for a racer that does not have HPI support in the area? Looking at getting a car but will need to stock the necessary parts to support the car. Thanks.

Ray it was a pleasure as well.

Doug - I would get the beveled diff gears, steering blocks, and if you want to always run the same caster blocks, I would get an extra set to be safe. The arms are durable compared to any other car on the market, but that could be a safe bet as well.

Anyone know the web address for Square R/c? If, there is one available.

PRP is working on an aluminum back plate.

When I was talking about a "board" track earlier, it was in responce to STNL's question about the barriers, not the carpet's base.
