Hey guys,

I'm considering different engines for a UAV project. The requirement for the engine is between 20-30 cc. Can you please suggest which engine you would prefer and why or which engines you had a problem with from the following:

DLE
DLA
3W International
MVVS
Zenoah
RCGF

Also, if you can suggest an engine that uses a fuel injection system instead of a carburetor, that would be great!

Thanks!
