Willhobby Hellcat Horizontal Stab ???
I see that the CMP and GSP Hellcats have an aluminum tube in the tail between the two horizontal stabs. My Will hobby hellcat does not. I have seen one of these hellcats (not sure of brand) flying with a Saito 150. The whole tail fluttered at full throttle. Anyone else have a will hobby without a tube? How did you stiffen the tail??
