More Updates:

Registration will be pre-registration only. Entry form to follow in the next few days.

Hotel recommendations will follow soon as well.

We also want to split the racing into two days where two classes will completely finish racing each day. A good turnout would be hard to finish all racing in one day, and for those who have traveled a good distance, it offers a better experience, while those who only wish to race a single class can attend for that day only.

We will also have a special race format once again for trans am.

More announcements to come....

Good to hear! Just an FYI, once the timing and turbo are ZERO'd, there is no performance difference between v200 and v203. There have been other changes to the software that helped cure some interface issues and the weird on-track issues, but the magic of v203 is in the timing adjustments.

Can anyone hook me up with a good TC5 VTA setup or a good starting point? I am having some serious problems getting my car to handle even close to good, far from good.

Go to the Associated site and find setups for the TC5. I have found that Josh Hohnstein's carpet set-up was VERY close...from there it was just a matter of massaging it (took a little droop out, stiffened up the rear, took "pro"-squat out and put it to neutral. Several little things that have all made incremental gains. Best bet is to put his exact set-up on it and then tune to what you're seeing the car do on YOUR track with YOUR driving style.

FYI, Hohnstein is no longer listed on Team Associated or RC10. I even checked the UK website.

Default VTA RTR

Just a quick question for you guys.

Is $450-$475 and unreasonable price point for a NIB TC4 VTA RTR/Race. Plus battery and charger. Retail price to build it in pieces would be around $570-$600 if the consumer did it.

I know the question was asked some pages ago and my thoughts were to build a TC4 with a Havoc system for sale here in my shop. It would also include RTR radio, tires,rims,painted body and appropriate gearing as well as a base line setup. Of course you could change out the radio to say the Futaba 2pl 2.4 for an additional upcharge.

Just a thought, what are yours?

when I priced out using one of the cheaper current touring cars (Ofna JL10-GT) on towers site, I was able to get with everything ready to go (and include the ocst of ordering direct from novak the cheaper 25.5 Havoc combo) a total of about $600 as well.

Though, the charger was a good portion of the cost as I looked at one thats had balancing built in which from what I could tell, the cheapest was the venom at $130. Lipo was $35, used the Parma body as it was the cheapest and is pretty durable at $18.

Radio was the tower hobbies brand 2.4Ghz at $80.

This doesn't include consideration of towers super saver club discount, so you can figure $50 off the total.

Managed to configure a setup for about $510-$540 on amainhobbies, which also includes the $130 - 150ish charge for the novak 25.5 havoc setups, not including any discounts. Similar setup, but was able to save a few bucks on a charger setup using the kyosho one and a separae 10amp power supply.

Default Spring Rates

Depends on which chassis you are using. "Wheel rate" is the usable number, and for that you need to know the spring rate, the shock angle, the length of the lower arm and the shock mounting location on the arm. There's a formula for that in a chassis book that I have, but I'm sure you can find something online searching for Wheel Rate.

Last time out on really high bite carpet with Jack the Gripper, I was able to increase spring rate on a VTA TC3 from 22 front/19.5 rear to 30 front/25 rear over the course of the day and still have plenty of grip. I used middle upper and outside lower shock mounts on both ends.

I haven't ever taken time to measure wheel rate, but the next time we get snowed in, maybe I'll make up an excel spreadsheet calculator. Sounds like a great iPhone app.

Speaking of which, there's a nifty RC iPhone app called Gear It that calculates FDR and rollout when you select your chassis and enter the pinion and spur numbers. Very handy.

thanks for the info. found what the spring rates are finally for the springs I have.

Default Spring rates

I stumbled on a great spreadsheet for many car calculations, including one for spring rate. All spring steel has the same modulus of elasticity, so you can calculate the spring rate of any spring if you know the diameter of the wire, the diameter of the coils and the number of active coils in the spring. I copied the formula out of excel:

=(1406250*A3^4)/(A5*(A4-A3)^3)

A3 is the diameter of the wire in inches -- you can use a digital caliper and be very close
A4 is the outside diameter of the spring in inches -- again the caliper comes in handy
A5 is the number of active coils

The result is in lbs./in.

I've used this with some springs of known rate and it comes out pretty close if you measure carefully.
