Last saturday I raced my 959 and Dynastorm on an indoor carpet track :-DD
First time I have raced in 13 years! Last time was in '93 on tarmac in Singapore.
Anyway... I had the OLDEST two cars at the meet, which consisted of 6 heats per category. Three qualifying and three races each. "Buggy" and "Nostalgia" classes in my cases. Both cars are completey stock, except for the rear shocks on the Dyna which I changed for adjustable, and the motor in the Dyna had to be changed to a SLOWER new 23 turn Tamiya BZ (my first time even of hearig about the new tamiya motors!) as per the race regs. I only have one ESC so had to swap it between the cars during heats!
Dyna came 2nd, 2nd, 3rd !!!!!!!!! :DDD Couldn't believe it! The times were even faster than some of the cars in the in the modern touring class - tb04 or whatever the modern trick carbon, metal ones are called. Fantastic fun. Running on carpet is totally different from asphalt! There is SO much traction that the car was doing wheelies acceerating out of alot corners. (adjusting the slipper clutch is boring, just get out and race it!) First two qualifiers were hilarious and horrendous at the same time. The Dyna was constantly three wheeling and cocking up a rear wheel so high it was a fight to stop it flipping in every corner. Was highly specatular and the crowd enjoyed it, but this wasn't what I wanted to keep fighting with. Ideas from everyone about stiffening the rear to make it rock hard only helped somewhat, but it was still lifting and flipping in the tightest turns. Eventually swapped the font springs for the orignal rears. THEN it handled like a great! The front had been so soft the dipping under braking was unbalancing the thing. Top fun after that, and staying out the accidents netted the good results.
The 959 ..... :=O I had fitted a celica centre diff to it the week before and hoped this would help. I started of using the stock off road tires. Absolutely zero traction and impossible to drive. The crowd was killing themselves with shouts and I was cringing in pain at the end of the straights as it slammed into the wall or barrier unable to stop in a line or make it round a corner.
Qualifying 2, I tried the orginal 20 year old! slicks and suddenly it was drift mania. Was infact alot of fun but using the orignal futaba stick type transmitter I could not control the drifts well enough and again kept loosing it entering and exiting corners. Lucky I have two bodies, the practice one is now sporting "racing incident" scars!! Third qualifying was much of the same. I was the last of the pack and desperately tying to stay out of everyones way when they came by. BUT - it was definitely just as fast as the others!! On straight I could actually overtake some of the group C cars.
For the races someone lent me some traction paint for the tires and this helped a bit, and I was amazed at the grip the slicks generated after using this and from heating up as the races progressed. For the races I also swapped the front springs for some MUCH harder ones borrowed from TC member "Manfred", *THANKS DUDE!!* he thinks he cut them out of a quick-drive but is not sure. I also swapped the rears for white springs from mini losi shocks. ALOT better, but still wild. It think I would have done better with a 'gun' style steering wheel transmitter. I really couldn't control the slides using the stick type transmitter.
Going to conservative fast in, brake late and straight, proved the only way to get around safe-ishly. Race one went ok, still last and flipping several times as the grip overcomes the high weight center during cornering. It's very painful to see and hear the precious shell flipping and rolling!
Race two and on the second lap the fancy celica center diff died on the 2nd lap. no-wheel or 2-wheel drive intermittantly. ****!! I don't know why yet, but it basically froze up solid. People suggested that it's becuase of the carpet fibre, but I cant see how they would ENTER the gearbox. Havent had a close look at it yet. Dissassembleming the rear gearbox is no quick job. After much time stress with the buggy races to run, I managed to change the diff back to the orignal and it worked fine. Still a terrible handful but I finished the last race. So all in all a cool day.
I've had for a while plans to change the front and rear suspension to accomdate TA01 or TB02 TRF shocks. I have the shock towers and some standard TA01 shocks now to test fit it. But after this weekends race I realise that that is not going to help alot on carpet races. Unless I get a Kamtec body I dont really want to race it again but it would be cool to get it competitive!! It has got the speed for it.
The main problem on carpet is that the slicks produce too much grip for such a narrow chassis, with a relatively high weight centre. Causing flippig. The off road tires were a worse problem. So now I am thinking about the following -
does anybody have experience on carpet with those old DUAL COMPONUND tires that came on the Can Am Lola and other early cars? I am wondering if that could be a solution - better grip but with a much lower break away point so it will eventually slide out rather than flip. But not oversteer like with the off road tires.
If someone from the car club posts up photos on the club race site I will link them here or post them up.
Race the vintage cars!!! :-D
