I just picked up some silver solder but am not sure what flux to use or what temp to solder at. I could not find the sta brite mentioned. I will look up the process on the net although I only have a propane torch right now. I think I will stop in at my buddies who owns a welding school and get an opinion on how to strengthen it.
Horizon says this is the last time I am getting warranty on these. I think they are assuming I am hard bouncing them and its my fault. I am not a liar and these float struts are fine and bullet proof on my 4lb .25 Eflite Cub, but marginal on a 9lb Cub.
I spent all last week back and forth emailing pictures and just trying to get someone to ship me a set.

Thanks again for the support, I am so tired of dealing with this issue, now missing prime fall flying season again, like last year.
