Stuff came today, turned out they actually ship from France which is annoying cuz shipment was expensive and had to wait few days :/
anyway, stuff looks decent, the bigger out turned out to be just a little too wide, 1-2mm less radius would be perfect, but no big deal, metal clamps seal it anyway. Anyway since this stuff is rated for up to 180*C i don't expect it to last on exhaust manifold which easily gets into 200+ range, with exhaust gases that it have contact with probably well over 300. Until now I was using this really cool loctite silicon tape, supposedely rated for 270* or something, but it also getting burned through after one tank or so. So im kinda lost, at first, with my ori rovan 45cc(running constantly at 180*c)~ i was sure it was this engine fault that it melts everything, but now have zenoah but it turned out the issue of melting connectors is still there, they just last a little longer....
I don't know hows thats not more popular issue? Seems like you need some 500*+ rated hoses, everything is just getting burned, i even bought special exhaust silicone rated for 1200*C(!), and pushed some of it between exhaust and manifold to seal off gases, but that also didnt work, it just got pushed out or something because after last burned hose it was just gone >.>"
Still looking for "permament" solution to this stupid exhaust. I think zenoah at least wont burn through that muffler hose away from engine, rovan engine burned even that
