I have a Harmon Rocket which I got off a guy at our club after he crashed it on landing.
He was running a 4 stroke in it and he never had a problem with the stabilisers.
I am wondering if this is only happening with the 2 strokes as they seem to go quicker?

I am in the middle of repairing the model for flight and am now wondering if I should sort this problem out while its in bits.
I will be running a 46AX in it too.

Am I better off taking the covering off the tail and strengthening it internally as I have to cover a couple of other areas on the plane.
Or should I just do the mod with the rods from vertical tailplane to horizontal stabiliser?
