Got the chance to take the truck out for a little running today (only with a random 3S and a 4S pack - the 5000mAh 3S TP packs are on order from rclipos - Pat there is great, I ordered them at 1:30am EST last night and got a confirmation at 2am EST that he would ship them out on Monday morning). As all are saying the stock springs are WAY soft. Rather than wheelie on demand, it was flip the truck sideways on demand.
The stock spring are white Front and rear Green. As other already mentioned the springs that come with the 120mm Travel kit are silver (28lb) and blue (33.7lb) and I just installed them tonight. Truck feels a lot tighter just compressing the body on the floor.
With Neu 1515 and MMM the truck weighs in a 9.2lbs. With batteries weighing in at 1.7lbs for 2x TP5000mAh 3S the RTR weight should be 10.9lbs. For it's size it feels pretty light because of all the plastic.
I have to say the tires are pretty decent. I hope to get another chance to run it before the weekend once the lipos come in. Running with the 4S pack was pretty underpowered on a 1360kv motor, but I only took ~1,600mAh out of the pack in just under 15mins.
Will post a few more pics in a couple of day with the batteries to show fit. But here's a pic with a 4S pack that it 30mm high. 1st pic - door closed with no battery. 2nd pic - 30mm high battery door open. 3rd pic - 30mm battery door closed.
