What size are y'all cutting your tires down to for . . .

Asphalt outdoor?
Medium bite carpet?

Front and rear sizes would be nice : )

I think the magic starting sizes were 2.21 and 2.20... I'll check (med bite carpet).

How's Mike's carpet this time of year?

Thanks Timmay.

Mike's carpet is awesome! Perfect traction! I can run 5 laps with my Losi Drift-R on PVC tires, and the bite comes way up! We probably have 250-350 racers twice a week. It's like a national event, wait, make that CARPET NATS, all year round. I am not even certain there's carpet under there anymore. It could very eaily just be foam and paragon! The whole area is always black, and no one ever walks on it for fear of losing a shoe!

Nice!

Actually, we find that for building a groove, nothing works better than 200mm pan cars. We used to use Speed Specs for this. Strap in a hotter motor (19t or 10.5) and have someone wheel the car around the track, re-doping every 5 or so laps. Don't wipe off the tires. First few laps after re-doping take it really easy, then work the throttle hard. We do this for 2 packs keeping the car where we want the groove. We usually do this on a freshly changed track. By the end of the race day people are setting fast laps. By the next week the track has a nice dark groove around it.

We only need to spray the track when trying to practice for super high bite. This backfired on us the second year of Vegas when the bite level never got above medium...

what servo are people running w/ their Formula 10s? The chassis looks pre-drilled (i'm still waiting for my kit on order). Will a JR 3650 fit (or have enough power)? Otherwise I'll probably run a Futaba 9650 or KO.

I have been running the Futabe 9550 (predecessor to the 9551). Works just fine. I believe that the chassis aren't pre-drilled, as there are so many different servo formats. It is critical to get it centered, so a one-size-fits-all hole pattern wouldn't suit racers.

Default Body selection for Formula Pro 10

Hi Bruce and others,

I ordered a Formula Pro 10 from you the other day (can't wait for it) and I'm shopping for bodies. Is the below info that I cut-n-pasted from your post 5 months ago still pretty accurate? What do you think of the new body "Sophia" Alpha Romeo? We're racing on low to medium bite carpet.


The Vette is very good all around. Easy to drive with a nice balance.

The Viper is a little more "planted" but a little pushy. Probably really good on a larger track.

The Diablo looks cool, but really doesn't work too well for racing.

Other good HPI 200mm bodies are:

350Z Nismo GT = Pretty neutral...rotates well.

Supra GT = Very good...feels a lot like the Vette.

NSX GT = Good again, rotates very well, but a little twitchy.

Silva GT = Very good..really neutral and easy to drive.

911 GT1 = Good, a little more aggressive than others.


Cheers,
Mark Taylor

I'm not Bruce, but I can tell you for certain that we have not raced at our local track since the IIC (Bruce's local track, too). Bruce mounted up the Sophia at the IIC and the shell is stunning. OD reported in the GT10 thread that the Sophia is really hooked up and is probably going to be one of the shells to have in the GT class, as he felt that he could actually compete with 235mm gtp cars.

I have one of these shells that I will be mounting up soon (probably spray-bomb one for tonight) so that I can give it a go. I really love the looks of this shell and can't wait to get it on the track.

Default Setup suggestion on SpeedMerchant Formula Pro 10

Timmay,

Thanks for the reply. Good info. I ordered a Corvette until I can get my hands on the Alfa Romeo (Sophia) body. Is it safe to say that the AR body has more downforce? We're running on a med traction track where downforce would be good.

Any base setup you can suggest for SM Formula Pro 10 on medium traction carpet? Springs? shock/tube oils? etc.



Thanks again,

Mark

I believe that the stock set-up should be close. I have been testing the sport version at our track and wound up with springs backed off 2 turns (.023) and red/blue mixed in the tubes (half one color on one side, other half on the other side of the damper rod).

However, the sport comes with the old school front. I believe that the guys with the Formula front end were running 5.5 caster and 2 camber with .020 on the front. If that is too much steering, you can switch up to .022. Get your pod droop correct, too; 2 - 3 deg. I've been running 40wt in the shock with a copper spring, I think I switched to red at the IIC. 4.5mm front and rear about 3.5 - 4mm center.

The protoform Vette works very well. I believe that Brian Wynn was trying out the Supra from HPI, and he wound up switching to the Protoform Vette. I had a beat NSX I was using in Speed Spec for a while I put on until my Vette came in, major transformation. So it is a solid performer in my book... From what I read into OD's post, the Alpha has more df, but is well balanced... I can't wait to run mine.

Thanks again Timmay,

I'll use your suggestions as a starting point.

Let me know how it goes when you run the new AR body.

Timmay you got everything right EXCEPT: A.L.F.A. (Anonima Lombarda Fabbrica Automobili) In 1915 Nicola Romeo bought the company and it became Alfa Romeo

Since I am a huge Alfa geek I feel it is my duty to point this out

I haven't run it enough to give a thorough evaluation of the body's effectiveness because I ran a Corvette on my Formula 10 at the IIC and I ran the "Sophia" (Alfa Romeo 8C Competizione) on my 10L3T on asphalt. I can say that my AE car was far better than it has ever been with the Alfa on it-not a little, a LOT!

Here's the set up I ran at Vegas, it is the exact set up Bruce gave me a few days before the race. The set up on the team cars may have evolved during the week but I was so thrilled with how good my car was I didn't touch it!

Protoform Vette body cut to min height, 95mm roof.
Lilac/Lilac 2.1"Front/2.2"Rear
Formula Front
.20 Springs
2.5 Camber
5 Caster
Short Front Holes
Middle Back holes - Gives a little reactive caster
Kimbrough Medium Servo Saver
Green Spooge on King Pins
35 Weight shock oil
Black Center Spring (one pound heavier than copper)
Stock shock mounting (not raised or lowered, just with the stock spacer)
2 degrees of droop
Battery Forward
.23 side springs just touching
Red Spooge in tubes
With the hand-out LRP 88 spur 32-36 pinion

The car was flat out awsome! way better than the driver

Only problem is if you don't already have a speedmerchant black spring (17lb) good luck finding one. I finally found some at Hobby Etc. and grabbed all 3, but otherwise, good luck.

I got mine a long time ago, and you have yours so that's great. I think I have a couple extra if anyone wants one

Otherwise the copper spring is really close or maybe one of the CRC Stiff, or Double Stiff or Stiff Stiff Stiff will do the trick (sorry I can't remember what they are, but they are some real stiffies )
