There is plenty of time as of this moment to allow the people that don't have the correct equipment to buy it. I say - set the rules now and be done. We are not talking about a huge change. It is a motor and esc rule. Most of these systems are relatively inexpensive. This is why this class is gaining poplularity. What will not work is having too many rules or options.

There has been plenty of talk and opinions about this VTA class. I say - let the board make a decision and stick with it. That's what they are there for - right?

If you let the racers decide - this is what you get. Tons and tons of different opinions and no real difinitive decision.

I am with PBR (can't believe I am saying this), but you need to be just like Speedworld and the majority that way you will get more to come. Build it up and then next year you can make slight changes if necessary. However, I believe that Billy's rules at Speedworld have been spot on.

Just my two cents - not intended to offend anyone!

I't sounds like the brushless and silver can debate will go on for awhile. Maybe the club can try a test run with one car setup with the 25.5 motor and one with the silver can at our first race in March or is it April. Since that is a non points race that would give us a comparison of the two motors. I'm going to talk to Jake and order up some items and start putting the car together.

I certainly don't want to nix any possibilities, but all we need is somebody winning more than once with either set up and the other will feel like they're at a disadvantage. It would be interesting to put both setups in one car and see how they compare.

Since this would be a new class and we are trying to see how much interest there would be for it. Would it be worth looking at running the class with all the VTA rules but allow either the 25.5 motor or the silver can for the first season. I'm not sure how much difference there would be in speed but it might get more people interested. I can see both sides of the issue and this might be the best way to see how the classes works out.

PBR....yeah, I'm well aware of how to calc that but we would have to have all of the variables done prior to the races...not sure it's necessary. We have several ratios available in our Slash class, hasn't been a problem there.

Brushless is more cost effective long term, silver can short term. Who knows how many we'll have in this class and how long it'll last? To raise the initial investment and monetarily push out the guys who are striving to get the class going doesn't seem fair. It's fiscally easier for an outsider to install a silver can motor and brushed esc (which they probably already have) than for some of our club racers who are there every race to buy into a brushless set up....just my two cents. I'll be in the class either way....

The wingless sprints sound like pretty much a sure thing...very exciting to have a new class that's sure to entertain!

I'll try to get the Board together this week or early next week to discuss all of these options and give everybody the info they need to make decisions and get ready to race!!!!!

The VTA class is fun. I plan on running the class this year at Speedworld and with the Ground Pounders instead of 17.5 TC.

I already have a Corally RDX and a Orion 3800 mah battery. All I need are the body, the motor, and the wheels and tires. I think I will spend around $150. Thats' a small price to pay to have fun.

I agree that the silver can motor is a cost effective alturnative. But, lets follow the rules so other racers can run the Ground Pounders VTA class.

I totally agree with Foxxrocket I would like to run the silver can myself.  it is more cost efective for sure.

My bad, i thought Gordon had 21.5, but he did say 25.5. (even better) It sounds like a real fun class. I'm all for"spec"racing.

I have a GTB speed control you can use David. All you would need is a 25.5 motor.

I'm not totally opposed to the silver cans, and handicapping them if they are faster. I actually really like the low budget option. But I say leave the rest of the rules as is. It will attract much more interest then if it's a stand alone class with a 21.5 motor.

Why don't we test this on the track before we shoot it down here? I'm not opposed to going to with all of VTA's rules if this doesn't work. But at least give it a chance.I'm on a limited budget, so getting a whole new brushless system is a big deal for me, and there are those who are in the same income bracket.

I believe the VTA class calls out for the Novak 25.5 motor only and the USGT class calls out for the 21.5

I hope the VTA goes through it look to be a fun class

Not to step on any toes, but why wouldn't you just run the USVTA rules? I understand wanting the let silver cans run for economy reasons, but can't say I totally agree with it. Speedworld which is the closest track running VTA uses the USVTA rules, they also run pavement sprints, just something to think about if you're looking to attract new racers to the GP club. (they also run their VTA cars on the oval at times which looks like a blast! That could be really fun with that class at GP events, one month road, one month oval)

I personally will probably not build a VTA car if the rules are different enough to not allow me to race it at other tracks.

figuring FDR is pretty easy.

spur ÷ pinion = "X" then "X" x internal gearbox ratio = FDR

internal gearbox ratio is the teeth on the driven gear divided by the teeth on the drive gear, be it belt or gear. (i.e. TC3 40 tooth ring gear / 16 tooth pinion gear = 2.5 internal gearbox ratio.

I like the 21.5 brushless for long motor life, mAh isn't really all that important anymore... not so sure on fixed final drive.....with so many different cars how are you gonna figure that out?

Jake, if you're considering the putnam car I can bring one of mine over to the shop so you can see it in person before you make any decisions. Just let me know.
