Ok I'm basing my project off of tires on my towtruck the dolly tires they are 16 inches tall. The heavy duty wrecker I'm doing the project on has 40 inch tires. Do I divide 40 into 16 and get 2.5 and just take every measurement on the truck divide it by 2.5 and that's my measurement for my project build

Just divide everything by the ratio if the tires.

Ok can you explain that alittle bit better can you break it down for me

sheograth

The tires are 2.5 times smaller, so everything else is 2.5 times smaller.

So I was right take all the measurements on the real truck put them in inches n divide by 2.5

that is very cool idea kinda like what i am building ...but what kind of engine are you going to use

HomeSkillet832

i was going to use a 10 hp briggs and stratton engine

It's a 24volt wheelchair motor it weighs about 16 pounds. What are you building and how big

sheograth

Those wheelchair motors have serious torque.

If the rig is base on something with 40in wheels, I'd say torque is what it's all about. Huge wheels ROCK!

... wheel chair motors ...are very powerful for how small they are ...but they need very heavy batteries which kind of sucks ... I am useing a 40+ pound briggs and stratton to make myself an R/C Demoltion derby car ...and yes i all the parts in a big pile and i am starting a frame ...but i and computer challenged and do not know how to post pictures
