Default Schumacher Mission not fast enough?

Hey guys,


I race at a small carpet indoor track, with about 2/3 straight and 1/3 corners. My Schumacher mission just can't keep up woith the other guys around the corners, because of it's loss of acceleration, and slips behind a bit on the straights too, can any of you tell me what pinion gear, spur or anything else to buy to make it faster and have more acceleration. Bear in mind i am running the 20t pulley, 86t spur gear, 25t pinion gear. Everything else is just standard.(p2k2 motor, only allowed 27turn stock)

Cheers

Not seeing the track and never running stock this is a guess but id say that your over geared, i run 26/86 and 20 tooth pully with a 12 turn at ashby and that has a looong straight. You might get more specific answers if you ask in "schumacher corner" theres some things you can do to free the drivetrain up a little if you havnt allready.

The Mission is a good car, that can hang with anything else on the track. Not all answers to being faster can be found with simply buying stuff.

Just a thought.

A general thumb of rule about gearing: At around 3/4 of the longest straight, your car should hit max. speed. If the track are without too many sharp turns, you might go one tooth up on the pinon. For technically tracks, go one tooth down.

I would try running the 17 tooth pully, it should allow the car to get up to speed a little faster. I would have to agree with Ian that it sounds like you are a little over geared, that is about the same final drive ratio that I run on our larger out door tracks. Try running a final for 7.0 - 7.2 range.

No I wouldn't suggest running teh 17 tooth pulley. I run on a fairly small track (70x40) and when I ran a mission the 17 tooth pulley was just downright slow. Yes, the drivetrain does spool up faster, but it spools up faster, and if you don't have enough power already, the car will look even slower. Trust me, I know from experience, once i changed to the 20 tooth the car was much faster. So you probably have slow motors, old/bad batteries, a non-free drivetrain, or you're simply overgeared. Just my 2 cents.

Are they stick packs? And you're charging them on a timed charger...uh oh not good. That is probably why. You don't get a full, good peak with timed chargers. If you can afford it, i would suggest investing in a good peak charger with varying charge rates and peak detection for NiMH cells, like the Reedy Quasar (or Quasar Pro depending on the amount of cash you have).

GET RID OF THE TIMED CHARGER

You'll never get a good charge unless you invest in a peak detect model (prefereably a quality version with adjustable charge rate and delta).

Yep, listen to Sosidge and Axiom about the charger.

I have been running two Missions (one in stock and one in mod) since they first came out. I have switched between the 17 and 20 tooth pulleys many times and I cant say I ever noticed much of a difference. If your looking for a big improvement I would look somewhere other than the pulley size. Motor and gearing, battery, corner speed and freeing up the drivetrain are all more important.

2 things. Sounds overgeared, but can't be totally sure without seeing the track, but for a general indoor track sounds high. secondly you really aren't going to get anywhere near full power with a timed charger. I know others have said the same, just ehcoing it!!
