JetMang-Usually there is always some additional work required with these glow fan kits other than just tossing in the Turbax with Electric power system.
Glow ducted fan kits are always on the heavy side with beefed up heavy ply formers, and C grain balsa sheeted wings. When you are putting 4 pounds of batteries in these planes you have to cut some weight out some where or get used to flying a brick with high wing loadings.
The lighter the plane.... The faster it will go
