Thanks! It helps a lot!

Thanks! Insightful you are the bomb! I was not really looking for a class on (how to) as much as the answer so I could continue my build. Thanks so much for your help!

http://www.wolframalpha.com/input/?i=24mph+in+5s Is where I got my acceleration from, my weight is 150 lbs Torque= acceleration x mass I am just trying to get a ball park idea of torque needed to drive wheel and HP needed in order to size motor and gears.. Can someone give me the correct values?

Ok, but I was thinking that my end calculation of 120 HP was really high, can someone give me the right wheel torque and HP? Just a rough idea so I can order a motor, and figure gear ratio's.

I forgot top speed should be 25 mph and should be able to reach that speed in 5 sec.

I am building a remote controlled toy vehicle, tricycle style powered by a single wheel. Weight is 150lbs drive tire is 24in dia when calculating torque needed and HP So far I have got acceleration as 7.04 ft/sec that times mass of 150lbs should give me torque, at 2112 ft lbs that times rpm of...

Trying to upload a drawing..

I will try to upload some basic plans

As a prop, will have a lightweight plastic cover that makes it appear to be a cow. I am trying to keep the weight very low to the ground to help with stability, would be interested in making it electric, but don't have much experience in that area, it will only need to operate for 3 min or less...

Using common automotive remotes give easy control to the electric motors and the hydrolic pump provides the transmission and cluch allowing me to be not have to control engine speed.

So what I am building is a powered wheel to drive a wheelbarrow type vehicle that already has two fixed wheels in front, my power unit will mount behind and needs to have variable speed and steering up to 180 degrees and wireless remote control. I am using a variable displacement pump because I...

So far I have got acceleration as 7.04 ft/sec that times mass should give me torque, at 2112 ft lbs that times rpm of 300 is 633600 divided by 5252 should give me HP of 120.6? That seems high to me. I was thinking it would be closer to 12 HP... Did I do something wrong?

Yes, will have variable displacement pump, with electric control want to power it with gas engine, but need to know torque value to order hydrolic motor, and to size engine.

Want to be remote controlled. And already have electronic seloniod, for that

Wanting to make a self propelled wheelbarrow type vehicle, wanting to figure out what size engine and hydrolic motor to power it.
