Building a trainer

Cammo:
Thanks. I have already started to looking into the references you gave me. Garden Trucking can be very dangerous to the wallet.

Espeefan:
Thanks for the info.

From what I am understanding:
A 23 turn motor will run say 25 miles per hour and have no pulling power
A 55 turn motor will run say 15 miles per hour but have all kinds of pulling power
A 45 turn motor is a fair inbetwwen motor to have a little of each but not a lot of either.

"Basic Magnetic Experiments" in grade school? How young do you think I am? LOL That was too many years ago for me to remember. But I understand what you are saying. It is what I thought but was not sure. When it comes to electrical... It takes two batteries to make a flashlight work...sometimes, that is the ammount of elecrtical knowledge I have. Now machine shop, Fiberglass, Welding, Tin Bending, and that sort of stuff, I can hold my own but never claim to be any sort of expert.

Ha ha, Tinbender! Yes, you've got the idea. Low turn motors tend to make more hp, but to do that they spin at higher speeds, and consume more current. High turn motors make more low end torque, and aren't so power hungry. Both motors will work in a truck just fine, but you need to gear the truck to make the most of the motor's characteristics. A 23 turn will have tons of power, if there is enough gear reduction. That's why the 4:1 reducers are really popular. Kind of like comparing a diesel engine to a gas engine. I didn't think you were much past 118 years old. I'm sorry if I insulted you, my friend! But the old electro-magnet example is a really good way to describe what the motor turns are about! A low turn motor, like the 23T that comes with the Tamiya kits, is just not going to be in the powerband sweet spot, at the lower speeds we tend to drive these scale trucks, unless you gear it down. Then it'll work just fine!

I'd like to weigh in on this.

The more turns you have, the larger magnetic field will developed. The other part of the equation comes from the number of poles the motor has. The more poles a motor has, the slower the motor runs. There's a direct relationship between number of poles and torque, for a given field strength.

Let's say a motor is rated at 2000 rpm, has 4 poles and has a torque value of x. If the same motor was wound with 8 poles, it would have a rpm of 1000 and a torque value of 2x. In either case, the same amount of power is consumed.

Hey congrats on your first build. They are alot of fun, i read you were looking for someone who does decals. There is a guy in london ontario canada that does them. They are water slide decals. I just put clear coat over them so they don't tear once they are on. His website is j-bot.com or. ca... i forgot but go on their and check him out.send him an e-mail if there is something you are interested in.even though it doesn't say 1/14 scale, he should be able to do it.i got my decals for my Blue Mule build in 1/14 scale from him.he is extremely busy so it may take a few days for him to get back to you. He does decals worldwide. Hope that helps you out.The other way to go is if they are generic decals you can take the picture to your local print shop and they can print them on vinyl. for you as long they are not copyright. Although some will print them if for personal use only
