This is my first r/c lawn mower. Everything on the mower i had on hand. The only thing I bought for it was the vbelt. I misspoke, I ment to say hbridge motor controller. Did not have any money to buy one nor do I have the skill to build one. Works really well with the switches. I wish it was faster. If I find a better motor I'll replace it. The motor is 24 volts.
