It's not come with an installation manual. But, is easy to install. serch on the internet "3 way air retract instalation". there you have a a lot of schematic.
Es un tren retractil bastante bueno para su precio, eso si la amortiguacion podria ser mas blanda y en los actuadores tendria que tener absorbedores de traccion... pero como digo para su precio, no esta mal, es suave y regulable.
LO PUEDES USAR EN CUALQUIER APARATO, TENIENDO EN CUENTA EL ESPACIO DE INSTALACION, Y EL PESO, TANTO EL QUE AÑADES CON EL TRENRETRACTIL (QUE NO SEA EXCESIVO)COMO QUE EL TOTAL EN VUELO NO EXCEDA DEL RECOMENDADO PARA ESTE TREN RETRACTIL...
I have used a Futaba Mini (not Micro) Servo for years to activate the air switches. There very reliable. Better than anything else I have tried. You don't want a cheapeie that strips out that's for sure.
The HS65mg is good as it has metal gears but it's a micro that has 31-lbs torqu the Futaba S3115 has 38-lbs torqu though and is $10 chepaer. and slightly larger servo but still small.
I can't see how it needs Air to come down. There is no other nipple. I have ordered this anyhow and will confirm as it should be here on monday/Tuesday.
OK, its arrived today. Really well built (5 stars). if needs pressure for the wheels to come down as there is no spring. other than that the system is fantastic!
the spring would be for them to come down in case there is no air pressure left, that is the point for haveing spring loaded. (if they are sping loaded )
these require air to move in both directions Air up and Air down

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.

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 (-:

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.
