excellent construction, very solid!Nice set, very good price for what you get. I put 100lbs into the tank for about five solid cycles, it's weak after that. Very low profile so they're good for 70mm jet with thin wings.
Issues - they are a little sloppy when extended. No big deal, just an observation really. More importantly, don't use the included struts - they are much too soft for all but the lightest models. You can easily bend them with pliers or on a bumpy landing. Find some 3mm motor shafts and order them with this set to use as struts.Great product , installed on the HK viper 70mm, fit perfect. I then used the alloy struts to finish it off. I would recommend these to anyone looking for a strong but lightweight retract . I didn't have any problems with the air tank leaking and it holds air overnight. Made a pull - pull steering system , I'll post pics in the file section .The fittings look to be very well made. i am pretty impressed. Really looking forward to getting these up in the air
