ive put these in a hanger9 bf109 they went in with very little effort ,I have done around 10 landings and they are working greatSorry to have to say this, as I'm normally a supporter of Hobby King products, but one of these legs just gave up the ghost half way down, without any warning - they hadn't even taken to the air and were being cycled just for set up purposes - no sign or smell of burning when I stripped them down - I suppose I was lucky, as had this happened whilst flying the model would no doubt have suffered serious damage.
My main gripe was that I'd bought these retracts when I started the build two years ago and they were out of warranty (ok, by a year) by the time I finished when they actually failed - no joy at all from HK - even though the unit had only had around a dozen cycles from new.
I think the best course of action and I know it's a pain, but it is to continually cycle them just as soon as you receive them.
Regards Colin (aka 'arry auster)The durability of the retracts is very bad, after a few landings with a plane
with a weight about 2Kg the bearing from the leg is allready very bad.
i dont know a solution yet for the problem.I ordered these retracts for my Seagull AT6 Texan 120 and they fit perfectly. However, upon testing they made a lot of noise trying to cycle and never locked up or down. After about 1 min. they quit working at all. After removing the units I noticed on of the motors was a bit loose in it's mount.
Unfortunately, I can't recommend these.
RJI experienced failure before flying the model I installed them in. I had already shortened the struts to fit. I'm probably not getting a refund. Yes, these are too good to be true, avoid purchasing these.I now have about a dozen landings on these now. they are becomeing sloppy at the pivot pin. the brass pin is wearing in the side frame. I really like them other wise and will try to correct this with a bushing or bearing but this will require some work.
