- Yes, I have no experience building hovercraft. However, I have spent some time looking
- at the toy versions in the toy store and some time visiting the local RC model
- store. Depending on how much flight time you need, you may find a better power
- source at the local hobby shop. Either one of the newer battery power motors
- used in an RC plane or even one of the self contained (gas tank is part of the engine)
- .049 gas engines. I suspect the biggest problem with the coolong fan is its weight.
-
- Good luck, sounds like a fun project.
