Pat: I wondered what happened to you Sat. I was waititng to see that S1 car run for myself. If you can afford to go house hunting in the Bay area you should have enough money to go to the Nats (lol). Oh well, I'll keep my eyes open for you in two weeks. BTW, finally got a great setup for Ripon last weekend...now if everyone else would just let me by, I would have won...

Look for mission parts, the suspension arms are the same.

I NEED SOME HELP! Ran outside today. Had to run stock and struggled on roll out all day. I did well, but the car was slow. What are you guys out there gearing stock motors with the 20 tooth pulley? Include your tire size, spur, pinion, pulley and motor I needed to be faster. Finished second, but I was SLOW! I have not had this trouble at all on the carpet. The outdoor track was about 110 x 50...
Rob, shoot for around 7.0 with the P2K2 and around 6.2 for P2K. That should put you really close. Adapt accordingly for any other motor- you know where the torque curves are I'm sure....

I want to buy a front upper-left arm on my mission and speedtechrc's site only lists it as "front upper arm" but there is a 1 and 2 upper-arm. Are they reversable?

Jon B.....both front upper arms come in the same package. You can not just buy the left or the right you get both in one shot. So what they have listed is for both arms. And no you can not reverse them.

No, they come as a pair- you get both 1 and 2 in the package. Almost all Schumacher suspension parts (as with most other man.) sell the parts as a left/right pair.

As a fellow Mission racer, I would like to suggeest a few parts that you should keep on hand even if you ARE a good driver...

upper arms for both front and rear
lower arms front and rear
hub carriers
package of ballcups (DAMN I love those schuie ballcups!!! )
one extra set of plastic dogbones
one extra front bumper
get the low resistance belts and keep the originals as spares
--- if you like to have extra parts on hand to rebuild a diff, make sure to get an extra set of the tungsten thrust washers. They aren't reversible, so you must replace them if they get gritty...

this is a minimum requirement list (to me at least) that will keep you racing in case of a bad crash- you can always keep more on hand if you can afford it...

Anyone else who has a suggestion, please add to my list.

Hope this helps you Jon....

Big Dog, I assume you are talking spur/pinion x internal?? That seems extremely low on the gearing. What is your overall roll out with tire size included? 1.05 - 1.20??? Any where in there?

I have not had any problems on the rug, but I have running on a 75 foot straight and an extremely tight infield..... I've been running about a 1.06 - 1.10....

Rob.....I run on a 120ft by 65ft track outdoors and I run 29 pinion and 89 spur with the 20t pulley I belive the final drive is 5.50 or something close to that. This was with rubber tires so I do not have the tire Dia. to give you to figure out the roll out. I had plenty of punch and killer speed down the straight and came back with 120 sec of runtime and the motor was warm but not any more then it would be inside. So if you have a set of rubber tires like sorex or something measure them and then figure out the roll out and thats what I would try.

Later

Rob,I'm sorry, I was assuming you were running rubbe tires outdoors. We only use FDR with rubber tires. Since I don't run foam, I don't use rollout. Maybe someone knows the normal dia. for standard rubber tires so we can plug it into the formula- then you can figure the correct pinion.

Oh, and I only run the 20 tooth gear outdoors...

Kevin- ouch- that's a pretty steep FDR. I must assume that's a P2K. I would start a little higher (Rob) and then go down from there. A 5.50 in the Memphis heat on our 100x50 track will most likely result in some pretty blue brushes...

Big Dogg.....I thought the same thing that I would end up with some blue brushes but I just kept adding more gear to the car and it never fell off or got too hot. I know that if I drove the car just flat punched around the track it will burn the brushes in one run so i try not to do that and it works out very well for me. I think is easier to drive an over geared stock motor then an under geared one. With the over geared one you dont need to pull it as much as in the infield as you would and under geared one. I think this leads to the brushes lasting longer and not getting as hot. Think about it like this if you drove a real car around the track in only first gear how hot is the motor going to get. Where as if you drove it around in second and drove to carry more corner speed what motor is going to be hotter and get worked more? I think the one in first gear and on top of it the one in second will be faster. Now this does not work for every track if the track is super tight and has a lot of short shoots then an undergeared motor would be better but on very large tracks that are some what flowing b/c they race gas cars on then the over geared motor would not be a bad way to go.
