Leo Best Posted April 21, 2015 Share Posted April 21, 2015 Just bought the SC8 4000kv combo, is there anything else I should order to fit the combo? You'll probably need to experiment with gearing once you get it. Zip ties and double sided sticky tape might be useful. And a deans plug if it doesn't come with one Quote Link to comment Share on other sites More sharing options...
scotty_b Posted April 21, 2015 Share Posted April 21, 2015 I have some 5.5mm bullets I'll solder to the ESC for the battery. The Turnigy Lipos I run have 8awg wires and I don't fancy soldering that to a Deans or XT60, so I'll just use the bullets that come fitted. Would I need and additional wire?

everclear1984 Posted April 21, 2015 Share Posted April 21, 2015 Awesome day bashing today! Broke a steering knuckle but a quick trip back to the car and it was ready to go again Oops And back out again Quote Link to comment Share on other sites More sharing options...

everclear1984 Posted April 22, 2015 Share Posted April 22, 2015 Looks like I have a decision to make. With my current set up the car is underpowered on 2s and runs very hot on 3s. So, do I gear up and keep running 2s or gear down and run 3s? Decisions, decisions. On another note, I nailed my first back flip today on 3s before it got too hot I'll post up a vid later on for anyone who's interested.

sean-vrs Posted April 22, 2015 Share Posted April 22, 2015 Gear down and up the voltage will run longer and sweeter! Quote Link to comment Share on other sites More sharing options...

everclear1984 Posted April 22, 2015 Share Posted April 22, 2015 Gear down and up the voltage will run longer and sweeter! I think that's the way to go as soon as I can afford a couple of lipo's. Do you think going down 4 teeth on the pinion will make much of a difference? I could hold my hand on the motor for a few seconds after a some speed runs today but it was uncomfortable.

Relativenewbyseb Posted April 22, 2015 Share Posted April 22, 2015 What gearing are you running at the moment? Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted April 22, 2015 Share Posted April 22, 2015 3500kv motor, 24/87 gearing. Quote Link to comment Share on other sites More sharing options...
Leo Best Posted April 22, 2015 Share Posted April 22, 2015 (edited) 3500kv motor, 24/87 gearing.Surely It would be better for the motor to run it on 2s and gear down a bit to 22/87 It shouldn't be slow with that gearing even on 2s. Better batteries maybe Edited April 22, 2015 by Leo Best Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted April 22, 2015 Share Posted April 22, 2015 Gearing it down and running 2s would make it slower. Nothing wrong with the batteries, one is a fairly new Zippy and the other is a tried and tested Turnigy. It's not slow as such, just slower than I'd like for what I use it for. At the track last weekend it was fine, but for bashing I want more power. Quote Link to comment Share on other sites More sharing options...

At the track last weekend it was fine, but for bashing I want more power. OK, go 3s and gear down then probably want to go about 4-5 teeth down on the pinionJust remembered I got some gps readings. 24.9mph on 2s, 39mph on 3s. That seems really slow for 2s and reasonably high gearing. What motor and ESC are you running Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted April 22, 2015 Share Posted April 22, 2015 It's a Radient Reaktor motor with a Vapor Pro ESC Quote Link to comment Share on other sites More sharing options...
ostewart Posted April 22, 2015 Share Posted April 22, 2015 I got 43mph out of my blitz on 2s, 28/84 I think the gearing was. Ran fairly hot but I get about 40mph from 26/84 and runs comfortably. Less teeth on spur means higher top speed less acceleration. Got for the 83t spur and 26t pinion Quote Link to comment Share on other sites More sharing options...

scotty_b Posted April 22, 2015 Share Posted April 22, 2015 (edited) That seems slow for 2s. I'm hoping for 40+ when my combo arrives. I'll be running stock 19/87. Edited April 22, 2015 by scotty_b Quote Link to comment Share on other sites More sharing options...
stretch Posted April 22, 2015 Author Share Posted April 22, 2015 (edited) I run 3500kv 2s 19/87 and perfect mix of speed and runtime for bashing, it's not mega fast but i prefer jumping etc no issues with temps either.

Turning the punch down doesn't affect top speed does it? That's the only thing I can think that I've changed recently Quote Link to comment Share on other sites More sharing options...
