Rccartips, I have not noticed any difference in speed,power or punch between my 5300 65c pack, and my 3200 40c packs in 17.5 blinky tc class... I doubt that there will be a difference in 21.5t 2wd Racing, and less vehicle weight.... As far as the 2700mah packs go, I think they might be too light and too low in the mah count to justify the price. 3200- 3300 mah seem to be the minimum in my view.... I make six Minutes mains easily with them, and only put back 1600 to 1900 mah to recharge them.... They also make my Car very nimble, and Quick around turns....

I add weight at the sides of the battery, between the receiver/esc and the rear pod. That way adding or removing weight in that placement does not affect front/rear balance. It's mainly tuning to the grip level of the track.

In our track, when grip is good, a 30g weight difference is noticeable. Right now my FGX is 110grms heavier than my F103.

Can't find much info on this ... I read somewhere that there is a rim that gives the car the most width.

Well supposedly the local bois that make the rules at our club race increased the allowed width for the series. Which i think 200-205mm was LeMans and 190mm was F1. But it seems they widened it to 205mm for F1 ..... Which I been wondering why their cars been getting wider and wider every time i see it LOL.

The F201 wheels offer the widest offsets in the Rear, HPI in the front. The wider local cars are not any faster so i wouldnt be concerned with it, not only that but as soon as our summer series starts the wide cars may not even be legal.

I am not having issues with this on our small tight tracks, only the large fast track.

Interesting...When you said you were doing a belt conversion I thought you meant the tranny. What you've done there looks very easy to do. Let us know if it is worth doing.

well, its quiet for sure! sounds pretty cool, can still hear a little bit of gear noise but not much. Since i am on the street i have no idea if is better or not but it seems to be much smoother on throttle, its suppose to rain here for the next couple of days so maybe by saturday i can track test.

So it sounds like most of the gear noise comes from the gears outside of the gear box? I would have thought it was the internal gears. Maybe the way the external gears mount there is a ms-alignment somewhere.

As you see it the belt slipped pretty bad so i made a bearing tensioner a few minutes ago and it seems to have gone a way, there is an initial click when you first take off but none while its moving. the pitch on the belt is not very deep so i may have to try something different if it gets outa hand.
I just found some pulleys that had an ID that was close and then reamed the holes out on the lathe to the correct size. it still doesnt like the 2.4 ratio so i dont know if this is even worth messing with but i willl play around and see. If nothing else the noise factor is nice!

One thing i noticed when i took the gears off is that there is a funny wear pattern on the external shaft gear but as the gear started to wear in the car was getting quieter.
