RE: CA v/s pinned hinges
Well, along the way I obtained I think 4 packets of pinned hinges in the last year or so. Now, just this one bipe will consume 21 Nos!!!
The CA hinges I used on my high wing trainer came off after a year or so- that was a cheap product. All the older airplanes I have inherited from my mentors all have pinned hinges. Those on my 2 year old Reactor 46 are still going strong. However my second airplane- the Phoenix Tiger 40 and second-&-half airplane - Phoenix Topstar 60 (UCD 60, inherited from my mentor) both came with factory pinned hinges. So its an even game
I know pinned hinges are considered a more "secure" way of hinging as compared to CA hinges. The CA hinge is as strong as the fibreglass cloth and amount of CA used on it. But the bigger concern is that CA absorbed into the hinge line makes it brittle. For pinned hinges, I guess you need to get some oil or vaseline into the hinge pivot before you epoxy them to keep them from binding, otherwise the pinned hinges are fine
This is not giant scale, its a 61 sized Bipe and I would like to gas it in due course. Gas only if I have reliability issues with glow again. So far my 91 has been dead relaible once set and if its sufficient power, I wont change it. There are 8 servos in this airplane and I would like to keep the weight down if possible. Like I said, best thing would be to retain the CA hinges now and think about it if and when they give up.
