How Could I Improve...

hi, what is the RPM of a perm 132 spinning a 15kg weapon

Depends on the voltage and the gearing. I dont know the top speed of a Perm, but whatever that is, thats the highest speed youll get. More gears in the gearbox = less speed.

Having the weapon driven as fast as is possible isnt necessarily the best solution though. The faster it is, the longer it takes to get to a level where it can do any damage, and the weaker it will be at lower speeds.

Also, that motor will require at least its weight in batteries to last a full match.

Oh, and by the way Joeys right, I forgot to add teeth. *gives Kody something for his cough*

well how cani i get the most kj out of a 15KG weapon?

Simply, you need to spin it at as fast a speed as possible, but what needs to be remembered is that if you geared your weapon to a very high ratio (IE: 1:3 (every 1 turn of the motor is 3 of the weapon), then it will take a lot of torque and a long time to get it going. My recommendation is you gear it down, it may be slightly slower but its easier to get spinning in the first place.

After a little research, a Perm 132 on 48v gives you 2300RPM, and since Perms are quite torquey, that will need little gearing, perhaps a 2:1 ratio. The actual KJ output, Id need to know the dimensions of the weapon (IE: what shape it is, how much of that 15kg is on the outside of the weapon.

If you can give me that info ben I can work out your weapons KJ output for you

4 arms that are 55 cm long leading to a 2.5 kg hammer on each arm

Ben, it is really unlikely you would get a system like that in 15kg. the hammers alone would take up 10kg, so you would only have 5kg left for the arms and pivot point. And you would need to brace the arms as well or they would just bend at impact.

fine 20-25 kg

Here are the stats on Twister Evo my first vapour

Colour: Yellow for the body, grey for the wedge, blue for the main section of the arms, red for the small angled sections of the arms and black for the 3 KG hammers
Speed: 10MPH
Weight: 100KG
Armour 5MM Hardox, skirts are 6MM Hardox
Chassis: 4MM steel box section
Drive: 2 NPC 1200s @ 36V
Power: 4 36V NiCad battlepacks
Locomotion: 2 aluminium wheels with vulkalon treads, 5CM in diameter and 3CM in width, with 2 front casters, all wheels are partially inside the body
Ground Clearance: 2MM without skirts, 0MM with skirts, 0mm at front and sides of wedge
Turning Circle: Zero thanks to 2 front casters
Size: Bodys diameter is 45CM, main part of wedge is 20CM wide and 40Cm long, side parts of wedge are 10CM wide at widest point
Weaponry: 4 55cm arms of which 5 cm just before the hammer is angled at 30 degrees leading to a 3KG hammer on each arm powered by 2 LEM 130s, plus a complicated gray fur-covered wedge to scoop up opponents, the fur is to hopefully either trap the opponent or provide a spectacular fire show
Srimech: May self-right when it spins upside down
Strengths: Will do damage to anything it touches, strong armour
Weaknesses: May not self-right, battery life may be short
