Yeah, I think the 5400 would be the better motor
I'll post some pics and stuff of my set-up later Monday after I get them off my camera
As far as tires, I couldn't find the "perfect" combo at all
During morning practice, I ran HPI Soft Rears and GQ 45 foams in the front - AND THE CAR WAS HOOKED UP!!!!!!!! but then came the 1st Qualifier and it was pure crap - traction rolling and everything...Basically I chased tires all day...HPI stocks wouldn't work - GQ foams were closer but not perfect...I finally ended up with GQ 45F and 25R - and I was VERY good, but get the slightest bit aggressive and I would traction roll
If I could have got something together with tires, I would have been unstoppable - the car was that good, when I didn't roll it I would say I was running faster than Pro TC
Even with the traction rolling, if I stayed smooth enough in the turns, I was outta this world quick - but if I did anything, I was rolling...
I did a couple of tricks and I'll post all that later...
BUt I have to say - this chassis/combo/whatever-you-wanna-call-it has to be THE BEST WEIGHTED CHASSIS FOR THE mRS4 and LIPO ever....if you hold a 6cell chassis and this chassis together, they feel just about the same...Like I said to all the guys I was talking too, the last time I ran BL and Lipo in my mRS4, the car never felt planted - this was perfect!! Mike really did his homework on weighting and balancing...Never once did I feel like I wasn't 100% stuck to the ground...I cannot even think of more words to explain how good this was...
But I'm babbling and I need to get in bed...
