The Ballistic is legal. It is the same rotor and stator as the SS series. Technically speaking, it is the same. It does have better tab location, an aluminum rear endbell/bearing carrier and timing marks on the can.

Bingo on 6.0, the car definitely was much slower.

At this point, we're going to keep exploring what can be done with the current legal batteries and motors. There has been some exploration of 1s, which was promising, but there are a lot of people who seem to be opposed to that sort of change.

It was a 66 Chevy II Nova model that raced in 1969. Right now nobody makes one from 66 IIRC

Ok. I am laying out what I am going to purchase, Here is what I got listed:

- Novak Ballistic 21.5T Motor or a used / refurb Novak 21.5 SS
- HPI4793 - HPI 26mm Vintage Racing Tire (D-Compound) (2)
- HPI4797 - HPI 31mm Vintage Racing Tire (D-Compound) (2)
- HPI3816 - HPI 26mm Vintage 5-Spoke Wheel (Black) (2) (0mm Offset)
- HPI3821 - HPI 31mm Vintage 5-Spoke Wheel (Black) (2) (6mm Offset)

I am going to be running this in / with the following:

- Academy STR4 Pro II (shaft car)
- Speed Passion GT2.0 Pro ESC
- RFI 4000mah 25C Lipo
- Aitronics 94357 servo

Now, my question is this:

- What bodies currently are the most durable to buy?
- What bodies currently are considered the best handling?
- What bodies are a great combination of the both?
- My Internal Ratio is 2.3 on the vehicle, with a spur gear possibility down to 62T. I am thinking for the 4.2 - 4.6 FDR Range to go with a pinion selection of 31 - 34T , does this sound about right?

the Camaro takes the best beating for me. The Cuda splits if you hit it in the nose real hard but HPI is working on one from thicker sheets of lexan. I have never raced the mustang. And Im not one to ask about which one handles the best.

I'll second the Camaro. The Mustang works well, but needs reinforcement. Handling, they are all roughly the same.

What pitch gears are you running?

I'll be running 48 pitch gears.

I decided based on the thickness of the lexan and that I like the look of the body (I know, I know) to give the Parma Boss Mustang a go. Plus the price was good too for a NIB body, I figure, for a beater body, can't complain.

So, anyone here got a 21.5T motor for sale?

Can I get a set of working gears that touch and make good gear mesh? Then I can come up with some numbers for you.

assuming 62T spur, 32 tooth pinion is smallest they show.

Of the legal bodies I haven't found any performance advantage/disadvantage... don't worry about that. The HPI Camaro is the most durable of the HPI bodies but the Mustangs aren't too far behind. Also the Camaro is a one piece body where the Stangs and Cuda are two piece. I also think its the easiest to mount "slammed". I think the Cuda looks bitchin' though... just reinforce the front. Actually though I think my fav body now is the Pegasus Mustang... not for everyone but I like it and is seems more durable than any of the HPI's. Not quite as detailed and no overspray film or window masks but it is really holding up very well.

I can tell you from my experience running this summer VTA seris at my local track, it looked like the Mustang was the most durable. Then again, I was the only one running a Mustang (HPI 1965 Ford Shelby GT-350) at every single race. All the other guys used Camaros or Cuda's. The Cuda's were the least durables. My car was the best handling one, but I don't think it was due to the body. I won first place in the series and honestly I don't think the body did anything to make the car handle better.

That puts you at 4.46 = ((62/34) x 2.3)

It also tells you if that is the lowest number, the lowest number of teeth you can get to mesh properly is 62 + 34 or 96 teeth.

If you make the spur a 66 and the pinion a 36, you can hit 4.22. I'm guessing you'll run out of space on the other end at around 64/28 for an FDR of 5.42. That's a pretty good range. This gets a tooth count of 102 down to 94. You will want to see if someone can loan you these ratios before you go drop cash on them first. Good luck!
