The HPI bodies have the best detail.

The Parma bodies are kinda wacked out versions of the real cars. But they're the strongest.

My latest HPI Cuda body that I got a couple weeks ago however, was stronger than previous ones. I'm hoping HPI has started making them stronger.

I love VTA. We do something different for the start of our mains every week.

Has anyone tried a "lawnmower racing" style start? You could have the drivers stand on the side of the track opposite the drivers stand with the cars lined up LeMans style and the drivers could run across the track and turn on their radio and car, then hop on the drivers stand and take off. Hmmm....we might have to try that one of these times!

As far as VTA goes, I think I agree with 2xs. I love HPI shells. I am an absolute fan. I think that HPI shells have the best mix of detail and usable durability, making them the all around best producer of Lexan body shells for RC cars. But if you are going on detail alone then I would have to say Tamiya and then ABC. Who dont make anything legal for VTA, but geez their stuff is nice.

Nope. But be prepared to go awfully big on the pinion. I've heard that 3.5 FDR is a good place to start. But that is all relative to track size, layout, etc.

If your car is up to the 1550 g weight specification, then don't be afraid to gear shorter. With a 100% USVTA rules compliant car, I got much better performance and lap times from a 4.2 than a 3.6 FDR. And the motor stayed cool enough that no fans were necessary. This was on a typical parking lot layout about 100' x 40' with a single straight and a curvy infield. Gearing too tall will kill your corner exit speeds where you need it the most. Just because the gearing restrictions have been lifted doesn't mean your old gear ratios won't work and weight is a factor. I'd say that whatever you were doing with your 21.5 motor, start with a pinion that is about 2 teeth larger and work from there.

Also, I suspect there will be much cheating, both intentional and out of ingnorance in regard to weight going on at the local level where cars typically aren't checked. However, the cheaters will be missing out on the handling benefits of a car that's 3.5 oz. heavier than the old standard. More weight = more traction on those slippery parking lots. Especially ones that are not treated with any kind of traction compound. I'll stop now before I give away all my secrets!

Also in a field of cars with mixed levels of experience, you fair better if you happen to rub fenders with a lighter car. There is less getting bullied off your line.

HPI struggled with this because you lose the sharpness and detail when you pull the shell from a thicker lexan. The Cuda has really nice undercuts in the front end, but that made it weaker in that spot and it shows if it takes a lick on the nose. Since the shell was being raced frequently, they decided to go ahead and make the production run from the heavier material. I think its only 37 grams heavier than the previous shell, but that measurement was on a painted shell. Most VTA racers need to add weight anyway, but a heavier shell doesnt help the center of gravity. I think it was a good move. The shell still looks great and it holds up much better to the rigors of racing. I dont think the added weight is much of an issue under the conditions that it is being used.

Yes, I'm sure the layout and size of the track makes a difference. I was running a 4.2 FDR and my motor was hitting 160f at the end of the main.

The heavier Cuda shell is great. My "original" Cuda shells were only lasting a couple of months. My current "heavy" one has lasted almost a year now.
