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.
