By the way, Thanks for the post, theBender. It was very informative, and I've had a hard time finding anyone else out there with a 4D.

Did you attach your skiis the way Tufflight said to, with those glue-on coroplast tabs? Seems kinda funky, but I've never used skiis b4.

I also have an Enduro, but not built yet. Do you have any suggestions for modifications or improvements?

I'd definately go with the flattest pitch prop and big diameter for your 4D.

Thanks again. Keep hitting the spacebar!!
