@ nick.
Arent the mag motors made to handle all the curent they need to get 3 and 4.5hp out of them?
And so my best bet is to use the big mag motor and use as many packs as i can spare the weight in my bot? _________________ Tim Team Reaper.

The mag motors are premium products and will deliver huge amounts of power. Ultimately, they were designed for some boring industrial task that doesn't include over-volting huge shock loads, bad cooling, stalling and high output - all in 3 to 5 minutes
Don't get me wrong, if any motor will go the distance, the Mags will. I was just commenting on the different model's relative performance. _________________ Australian 2015 Featherweight champion

It looks like ill go the s28-400 and use eather 2 or 3 packs depending on the performance i get with eather combination once the bot is done if i can spare 3 packs. _________________ Tim Team Reaper.

Hmm, the Mag gets pretty hot for just 570 watts The good news (for the spectators ) is that I am adding 3 cells, not two, and EDTsim shows the Mag developing 775W. Interestingly, to get the advertised power of 3hp (2250w) from the MAG motor, EDTsim needs three of the 24V battlepacks - not too many bots can be getting the full capability of the motor...
Can name one or two. Most people are going onto the technobots Perm motors over here though.

Which would have more kinetic enargy?
A long hollow drum that weighs say 2kg or a shorter drum with thicker end caps the same diamiter as the long hollow drum and the same weight? _________________ Tim Team Reaper.

Well iv had to opt for a smaller drum possibly heavyer and for the weapon motor im using a model plane starter motor at 18v to make the robot still invertable.
so the weapon wont be ass efective as what it started out to be
But on the plus side it now has 4 drive motors _________________ Tim Team Reaper.
