Might be a noob question here, but I picked up the HPI driver and cannot figure out how to mount it to the PF Firebird body. Any suggestions?

What brand of car, but short of that you can take a spare piece of lexan bend a 90 degree bend in it and then bend another 90 degree angle 1/2" up screw the first 90 to the top deck through the slot in the top deck. Then servo tape the drive to top of the other 90 degree bend . You are making a 1" wide lexan Z bend. This will position the driver driver over the motor..
That's one way to do it.

If you are talking about the HPI104815 (or similar) driver set, I just use ShoeGoo. I glue the head to the roof and the little front tab under the windshield. Works like a charm

I'm running the TC4 in this class.

Maybe, treating the asphalt could be the answer.

Not my call, that's the track owner/RD's call. But we don't have any problem racing on untreated asphalt. The racing is good, fast & close.

Speaking of Driver Figures. McAllister Racing has a full interior that can be used, but we also have a Sprint Driver that works well and is primarily just the driver which is much smaller.....

A short 5 minute main? And an amazing consistency in driving regardless of this, wheels or motors.

Default USVTA Tire Rules

As of January 1, 2018, only the Protoform 10139-00 and 10140-00 tires will be allowed for official USVTA events (Scale Nationals, Southern Nationals, etc.).

The HPI tire supply has become scarce in most situations, and Protoform has stepped up with solid availability. Allowing both tires creates a "haves and Have - nots" problem if one tire works better.

For those racers who have HPI tires, tracks may allow you to use those tires at club racing events at their discretion after January 1. While this is acceptable to allow racers to maximize the money they have spent on tires, official USVTA events will not allow HPI tires after January 1.

Clearly there's only one answer Myron.....ROADTRIP !!
Pack your undies, your car and a couple sets of those POS tires and head on down to NC. Do some laps with those poor,suffering racers and and show them the error of their thinking.
How sad that VTA has come to this.
As someone who was once very active and loved VTA for what it offered, some of you folks should be ashamed.
I've watched Myron and others break their butts for years trying to keep this class alive. Somewhere along the line it became to much about the petty crap like 0.5 seconds a lap and less about really cool looking scale type bodies, reasonable power given the limitations of chassis that didn't have to be the latest and greatest and TIRES that everybody knew were more about scale looks than super grip performance. I believe Myron ran a TC3 or TC4 for quite a while and still put a whoopin on a good number of 1 percenters.

Sorry Myron and anybody else for the rant but sometimes it's worth using a 2x4 to try and make a point. Race on people and have FUN....it's probably gonna cost you 0.5 seconds but it may be worth it.

Hmmm.... I still have 4 pairs of HPI fronts and 2 pairs of HPI rears that I won't use by end of year. Hmm... I'll have to ask the track owner if he'll grandfather them next year. Or only use them for practice I guess.

The HPI tires will be allowed at Kannapolis Raceway Park for as long as there is a viable supply of them. If and when we host one of the major races then we will of course comply with the recognized rules and regulations. Since we are a new facility we do not want to create an additional expense on those who attend that may have been out of the hobby for a while.
