Drive System Advice

[typhoon_driver]

I imagine a single rage bridge should be able to handle that. Just don't adjust the current limiting settings on it (we never touched ours and it was fine) and give it a test when you have the machine together for the first time. Give it a short burst of driving around nice and slowly. Stop and touch the heat sink to see if it's getting hot. Then slowly speed up until you are hammering the hell out of it.

Also make sure you gear the robot for a sensible top speed.

I agree with Gary, if you don't overdo in speed , the ragebridge 2 will do the task.

Just to give a comparisation, Bullfrog uses 2 24V 1.2Kw Iskra on 37V( theoretical power 2x2.85Kw) 2x5S 8000mAh Zippy LiPo) and an old Robotpower Sidewinder (2x80A channels), but with a 20-1 gearratio on 280mm wheels.
Top speed isn't blistering, but due the big gearratio, we get there very fast,giving it the impression of great top speed.

The 24v, 800w scooter motors work well on 6s. We used them with a 4:1 chain reduction on 160mm wheels with no problems and the speed was pretty good.

What speedo did you use Will?

We used a Wotty for s2 but we're changing to a Roboteq Ax2850 as the Wotty is going back into Maelstrom.

I'm big wotty fan. Ironside runs 2, one for wheels and one on the weapon motors.

The wottys are good but they are rather bulky. I couldn't believe how small the ragebridges were. I'm also impressed by the size of the vex victor BBs.

That Optipower discount is very tempting...

Great information shared on this thread, really useful, I've ordered all my parts and they are slowly arriving now.

Wondered if you guys could offer me any advice with R/C Systems, the one I mentioned originally in this thread is a cheap one £25 on hobbyking, but what should I be looking for when purchasing a R/C System to work with my RageBridge? Any recommendations at differing price ranges?
