I'm happy with the set, you get a lot for the money. quality struts. My only bug was a missing screw on the nose retract mechanism but I had spares. If you think this set at 60$ will be just as good as Robarts for 400$ you are dreaming, dont complain because it's not the same quality, but for the price it's a great alternative.

Got mine and it came without manual and the air tank is dent in several places. 3rd problem, the air refill valve is not working. Anyone from your customer service can help with this ? Can not rate this, almost feel sorry I bought this one.

Well the only thing I can say is that it will not extent if you have catastrophic air loss ....hence belly landing. Apart from the this kit is brilliant and if I get another plane requiring that size, then I will be buying another. Thanks HK.

Mechanisms comes.
Perfect system, all the accessories of good quality, too big selector, slow motion regulation problem, no T connections, and no Quick connections. Massive system, can hold 7 kg, I am using P 38. I write about product quality after a few flights .... Soon (-:

received mine today and they are brilliant. Very solid built out of aluminum and steel. Simply has to be seen to understand how solid and well built the landing gear is. I'd have no hesitation buing them again. Everything is a smooth fit with smoth travel movment.

Thanks Hobbyking.
