Default FunFactor Tuning & Gearing Questions

Hey Guys,

I'm new to nitro, I just bought a FF-ATX (first nitro) and HOLEY-MOLEY I'm impressed with the performance. I have only run 1 gallon of nitro.

My FF is bone stock for the moment but I just bought:





...and since you guys say the chassis flexes too much




I want to convert my ATX to a MT2. Is everything the same except the front shock tower, tires & the gear ratios? From the pics I looked at on this site I have the .88 axles...is this right? CEN's website confused me. I dont know if I have .66 axles or .88. I need to order new ones anyway because I had a head on collision at full throttle with my friends Tamiya RC-10. I broke one axle and two diff. cups. I will also be doing the duff cup mod you guys recommend! (The RC-10 was almost destroyed)

Here are my questions!

1) Can I get more power? My stock engine was tuned at a local hobby shop. Its running at 230C. I have not touched the settings since. Can I do more tweaking if I buy a temp gun to get the front wheels off the ground? I had to adjust 2nd gear on my ATX because it would take forever to engage with the stock setting. Should I run 40% nitro or stay with the 20%?

2) To do the .18 engine upgrade you guys are talking about do I need to buy a new engine or just a piston and sleeve? Do I need to do any drive train mods to handle the extra power?

3) I want to play with the gearing a little. The stock gearing is too tall for me. I want more low end drifting power and a 2nd gear that does not take the length of a football field to wind out in! Can I just start swapping spurr gears or do I need to use specific size pinion gears? Can someone recommend me a good gearing setup? Also, did I read correctly that I can upgrade to steel Genisis spurrs? Is there anything I should know before ordering a bunch?

Tnkx for the help guys. This site is SWEET!

My future mods will include 14MM wheel hex upgrades, T-Maxx axles, T-Maxx shocks and maybe try the T-Maxx clutch springs. I'm going to try and make an aluminum front diff. case too on my CNC mill as I broke one of the mounts for the upper contol arm. Is there a mod for this to save me the work?

Everyone I know is TOTALLY impressed with the bone stock ATX!!! (minus the pathetic diff. cups and axles)
