There has been alot of question and answers on the rccombat.com topic forums, just do a search on HOR and plan on being entertained for a hour or two.

Consensus is that the L channel is stouter than the C channel. You can get by without cutting the top center of the wing, but it would then take you 3 or 4 pair of hands to hold everything down.

You can use the L channel to build a conventional tailed plane, just turn the L channel over to where the flat part is on top. Gunfighter flew one in the Tyler SSC and was very competitive with it.

Phillip, where are you in Houston?

If your interested in flying some combat, we fly most every sunday at GCRC in S. Houston.
