Zero turn r/c weedeater

[Gee]

Sound like a fun and cool project. I would like to see this one James. It might just be in all the Wal-Marts by Fathers day next year if you pull it off. You could end up a millionare. No worries, I'd stick by you and still be your friend if it happens.

Hey Hey, Outrunner Man here. LOL

Stumbling across this thread kinda freaked me out. Looks like we're going to be building somewhat similiar machines. That's cool with me dude.

Let's make it happen. It's gonna be a war on weeds for sure.

Just to pass on some information here. The weed terminator head warns not to spin it faster than 8000 rpms. So base your figures around that to be on the safe side.

"My question is do you guys think that outrunner will be enough to power the blades? It is rated for 60 amps, and at 10s that will be 2200 watts. My intended use will be going around oples and trees, not cutting thick grass.+"

I asked myself this also. Then took a look at an Electric Weedeater I have that runs on 110 house current. The spec plate says 7 amps. Hmmm...........

7 amps X 110 = 770 watts. Just over 1 electric horsepower.(746 watts)

Let's not forget rpm's either. The outrunner you linked is a 400kv version. On 10S, you will be spinning the blades waaaaay to fast. On 4S, you'll be spinning the blades around 6000rpms.

Will it have enough power? Yes. If you spin the blade at the right rpms, and the motor can handle 1500 watt bursts, I think you might be surprised.

2 cutting heads? Belt or chain drive? Naaah, make them direct drive and use two motors. What shaft size will your mower deck motors have? I'm using Prop adapters for airplanes for the hookup. Direct hookup, no modifications.

If you do use outrunners for the forward movement, it will require alot less gear reduction. They have more torque and are more efficient.

This is going to be very interesting Linc.

I have made alot of progress on my build and will be updating my thread with pictures and info soon.
