## Questions & Answers

**Q: What is the gear ratio of this motor? Im guessing around 5 to 1. Although id prefer a 6 or greater to 1 ratio?**
A: The gear ratio is 5:1

**Q: what is capacity of this motor?**
A: It can work and fly model untill 80 grams of weight

**Q: Fit umx radian?**
A: I fixed one of mine that i had crashed

**Q: Is this the same motor as the Sport Cub S?  Need to replace my motor.**
A: The planes are about the same size.  They look similar but must be slightly different.  The Sport Cub S 2 has this part without the motor HBZ4430 but the Champ has this one without the motor HBZ4929.  So different model number, not sure if the parts are actually different or not.

### ⭐⭐⭐⭐ Good fit, Wires come short
*by J***R on July 14, 2025*

The motor fit perfectly in the fuselage. Be very careful when removing the old one, as cutting through the glue tends to pull some of the styrofoam along with it. I was able to fill in the damaged area and install the new motor without any issues. I did have to slightly loosen the plastic retainer on the back of the shaft, as it was a bit too tight, I don't see that as a flaw, just a minor adjustment; however, I did notice the upper shaft had no lubrication at all, so I added a small amount of sewing machine oil. The main issue I encountered was with the wiring, the new motor’s wires were far too short to reach the connector on the board, I had to cut the wires from the old motor and solder them to the new motor’s leads to extend the length.
