    Pinion change?

    Ok im running 2 of the flight max 2200mah lipos in parallel.

    Does the optional pinion make it faster or slower?

    Smaller pinion makes the truck accelerate faster but the top end is slower.

    how much top end are we talking about? all the acceleration seems to be in the first 20-30 feet on the stock pinion. i was coming home tonight to ask this same question, for nothing else than so that if i "want" to run series i don't have to worry about swapping. I'm bashing with this little guy if it makes any difference.

    ok so if i wanna run series is it ok for a couple minutes on stock pinion? Like if i want to show someone the difference and knock a double backflip out of nowhere. Its not gonna hurt anything as long as im doing any big long speed runs right?

    I think you will be looking for trouble if you go to long using series and 28t pinion. I would personally gear down unless if you are planning on only making a couple of passes. I would also watch your temps really close. At worst you will just thermal the esc.

    You will loose about 5 mph in the top end with the smaller pinion, but if your bashing like you say than it doesn't matter because you want that extra. If your racing on the other hand it's best to gear your car accordingly to your track. I am using a 19t. Gearing down also reduces your temps which is good if your running to hot. I pulled mine off the track the other day and the motor temp was 105 and the esc heat sink was barely warm and thats in 95 degree humidity after about 20 mins.
