We are rushing for completion in time because of the great turnout expected for this event. There will also be a much higher and longer drivers stand that will easily be able to accommodate 15 or more drivers during practice.

Homestead RC Raceway is looking forward to having all of the GT Racers entered having a great time and provide you with a memorable racing experience.
Doug,

That's great news, our GT event is getting even better!

OK racers, get them cars ready....... it's on!

Is it March yet?

Doug,

You are the man. It is understandable how you guys are making Homestead one of the best tracks in the country. Great news.

GT - something to consider: you may not want to cut all the relief holes in the chassis for two reasons - the durability would increase without the holes (or at least with fewer holes), and it raises the CG by installing a lighter chassis. Now, if the car is grossly overweight it makes more sense to go as light as possible and adjust the rest of the car to accommodate, but that's not the case with the GT cars. As I understand it, rules are being written to keep the weight limit reasonable so you don't need to spend a fortune to get down to minimum. It looks really cool with all the holes, but it may run better without, and I'm sure it will cost a lot less to manufacture. The chassis is the best place to be carrying extra weight because it's at the lowest point of sprung weight. The higher CG isn't such a big deal, but anyone using the chassis will have to raise the roll center on the front and rear suspension to compensate for the change in CG. Durability would be the biggest benefit and it would still be lighter than a stock chassis.

Durability would be the biggest benefit and it would still be lighter than a stock chassis.
The stock weights of the GT cars vary dramatically (2 lbs.) yet they race together. The varying power to weight ratios of the cars are locked in with engine limits. I agree the CG will change. There will need to be suspension adjustments after the CF chassis is installed. I have measured the weights of the components and have found that the chassis is the component that varries the most between cars. The DM1 as a whole is almost 2lbs heavier than the IGT. The dm1 spec is a little over 1lb heavier than the IGT2. The carbon fiber chassis gives the racer flexibility in the realm of power to weight ratio. It allows the racer of a DM-1 Spec to match the power to rate ratio of the GT2. For the racer that prefers one car over the other it give them the option to match pwr.

I agree that less holes is more durable (ther is a solid version on the way) but the CF chassis was designed for the experienced racer. Its not for everyone. If you are reading this than you are experienced. Its definetly not for beginners that want the fastest thing right in the beginning. Anything hitting a curb or wall at 50+ mph is going to be a bad day. I do not recommend this to guys that just entered the sport.

Was at the Homestead/Miami R/C track yesterday. Doug & Johnny of the R/C club showed me some of the renovation plans for the Speedway track.
The "Crew" down there in Homestead is hard at work and it's looking real good.

They've got some great plans for the layout & facilities. All I can say is we're going to be racing our GT cars on a big track guys, so get those race cars ready for some serious World-Class" action.

Only paid racer entries are secured spots, if you're on the list, please get a move on it. Registrations are open again for both GT1 & GT2 classes.

Is it March yet?

Have you thought about just shipping the heavy stuff to the hotel? Then just putting the rest in a suitcase?
