gearing for a Neu 1515 /1.5d for my 3905
 

I just managed to nab one of these bad boys. 1515 /1.5d

I don't want to buy a bunch of 5mm 32p pinions so does anyone have any recommendations for gearing. I can pick up any spur, but I need some suggestions on a few pinions. I'll be running dual 2s lipo's for 4s25c setup.

I am looking to get some good run times from my packs while getting a good ammount of torque and some good high speeds. I am looking for good bashing times and some 'wow' factor.

I was thinking of running around a 14t or 15t for an FGR of 25.34 or 23.65 respectively for some low temps and good run times.

I am also considering running two 3s25c packs in this bad boy. I will be running a Quark Monster Pro.

Ideas on either setup?

Apparently even though the Quark Monster is toted as 6s compatible, it can burn up running 6s. Make sure to do the heatsink and cap mods before you try to run 6s.

Second, as far as you requirements 'good runtime, good torque, good highspeed' - well thats pretty much what we're all after isnt it? :P have a look at http://scriptasylum.com/rc_speed/_top_speed.html to get some top speed estimates with different pinions - I think aiming for about 40mph is usually a good place to start, and adjust from there.

What capacity are your batteries?
