I know the revo comes with a 15/38 spur/bell combo and I NEED way more launch from this thing. I have done a few things so far to help lighten the load but I still can't get it to take off like it needs to when coming out of a corner. I need almost buggy like performance if at all possible with the 3.3 trx motor.

I am thinking of going with the RRP 14/40 combo to try and get this thing to rocket out of the corners.

So far I have done a FOC, alum pushrods, close ratio gears, tasis pipe, alum f/r shock mounts.

Future mods are going to be ROTO start for sure, tekno rx box, throttle servo mount, batt box, extended rear a arms, larger fuel tank, center diff/rear brake kit, alum turnbuckles, titanium hinge pins, steel cvd's, single steering servo, alum rocker posts. Only as money permits.

By the time I get that far into It am not sure if the 40/14 combo is going to actually be the best option. I hate to spend the money on something that I am really not going to need to reach my final goals ya know.

Right now I am noticing a slight bit of hesitation on initial take offs and it doesn’t seem to spool up as fast as I would like it to. Don’t get me wrong it is fast, will tear up a stocker, but it still isn’t quick enough on launches.

I guess something else that might need to be answered, is it going to be possible to obtain that buggy take off and spool with a revo

BTW this is the track that I am running on most of the time,

We run stock 15/38 but do run the center diff and it flat out launchs. Especially out of a corner. We are running sway bars now and that helped alot as well. I would not spend money on the cvd,s or the aluminum rocker posts. They just won't hold up. I would stay stock on the posts or go lunsford TI. The aluminum will snap on you. We run pretty much what you listed , all the tekno, MBX5T tank, MBX5T wing mount,single servo, all slaydens steering mods, 5castors forward, p3 rockers, anodized shocks white springs front/ orange rear, titanium pushrods and turnbuckles, sway bars,RD racing carriers and 23mm adaptors, 3.3 RB Mods with side pipe and bump start. We stay stock on most of the wear items.

well I really appreciate the input. how and where are you guys getting sway bars from? I do think that will help me a ton in the corners. I have tried lowering it as much as I can, but it still has a tendency to flip on occasion. I guess my next buy will have to be the center diff and see what that does. That and some lighter tires and rims. THX
