i liked those tvps still have them on my nitro Savage strong and sturdy, you'll like them. specially if you have a pull start more room back there to get the pull start lol.
i have a hobbytown about hour away i don't get to that one much, its nice has alot of parts variaty, but a long drive for just a couple of parts. i do have a local shop here in town but odd hours tuesday through friday 5pm to 8pm and saturday 10 to 5 i think, closed sunday and monday. i think...
i run 6s cause once you do you won't want to go back, lol. Yes, you may go through more parts but there are ways to take care of that upgrades....lol. i run the "bullet proof" diffs in my flux and the some HD gears in the tranny i really haven't broke to much driving my flux i have shattered...
the Pro-line super swampers are a nice wide tire not sure about weight but don't think they weigh to much more than the stock tires should be able to run stock gearing i was. they came pre-mounted on the wheels so i don't remember what they are but there nice too and are 17mm hub
Ran it yesterday and man those tires either it's the traction on them or the weight but my hs-7950th servo with 403oz of torque wouldnot turn them while on the ground.....lol
I do beleive and someone correct me if I'm wrong but if your receiver isn't high voltage (I don't think the stock one is) to you could fry it. I've got high voltage servos to but my receiver isn't so I still have to run a voltage regulator..to drop it to 6.0v.
