The indoor track is 125 x 65 feet. The back straight is 125 feet and I can barely hold full throttle for 1 second on 3s. Probably get it up to 40 or so. The fastest nitro's can't hold a candle to the car down that straight. It ain't even close since the acceleration with the 1.5d is so fast. My biggest problem is slowing the car down for turns. I accelerate so fast it is hard to take tighter turns and really easy to over jump. I am getting a Mamba Max today, so I will see how the adjustability of punch control, etc will affect my driving.

The outdoor track is 200 x 125 feet. I haven't driven the car on it yet, so I don't know if the 4s is going to work better than the 3s. I will know in a few weeks. However, the 3s works a lot better on the indoor track dimensions.

I would think the 2d would work pretty well on 3s. It really depends on how fast you need to be for your track. The 2d on 3s will probably be just as fast as the nitros in terms of top end, but you are going to accelerate a lot faster, so even if they have higher top end, in most cases it won't seem like it unless you are going down a very long straight. I think at rctech there is someone running a 1515 1y (2200kv) on 3s in a truggy and they really like it.

Honestly, I like the 1.5d because I do a lot of street bashing with my car, so being able to gear up for senseless and retarded straight line speeds was important to me. However, I will say that the 1.5d is overkill for most race situations from what I can tell. I am just getting into racing and will probably tone the car down to a lower kv motor as I get more competitive, possibly a 1509 size motor running on 4s for cooler temps and longer run times. From what I can tell, on the track slow = fast.
