CF rod won't bend and hold a set, but it will snap when it gets to a rigid mounting if you "land" hard enough.
I'm using 0.08" dia. and 3 1/2" length on my Tiger Moth. It snapped off once, but that was more of a crash than a landing. Seems to have just about the right spring for normal landings.
I replaced the stock wire axle on my Soarstar with same diameter CF rod. One side snapped at the junction to the wood block on the 4th landing. Landing was a touch on the hard side, but not excessively so, IMO.
I've since gone back to the original stock wire axle. As genebond said, better to bend than break.
I'm considering moving up to a thicker diameter CF rod eventually, but to do that, I'd have to:
1) route a wider groove in the wood block axle mount
2) ream out or replace the wheels
3) buy new wheel collars
4) replace the spacer tubes
5) ream out or replace rubber grommets for wing struts & floats
Worth it? We'll see....
Anyone know where to get replacement rubber grommets? I just know I'm gonna lose a few of 'em.
