I have some struts that leak air. I followed the direction for adding oil etc.

Has anyone tried using BVM thin lube in the struts to stop air leaks?

I have a couple of older Skymaster jets that had the same problem. Over time, fluid will start leaking and no air will remain inside.

I solved the problem by using high viscosity silicone like the one used for RC Cars. http://www.ofna.com/fluids.php

The one that originally comes from the factory is way to thin and and with a higher viscosity you won't have a problem again. Currently I'm using a 7.000 weight.

You can also try to use something like the Dow Corning 55 Valve Lube to lubricate the o'rings and keep them in good shape.

Yes, like Gonzalo, I also changed the oil. I am now using a power boat power steering oil with good results.

Cheers,

I may get a new set of seals from skymaster, and I am also going to try thicker oil.

Thanks for the advice, I think my local HS has the car oil but if not I will look into the power steering fluid.

Emailed Skymaster and they are sending a new set of seals. Not sure if they will charge or not, just asked for my address.

I picked some heavier RC car diff oil as well, 7000w.

I wasted a lot of time taking these apart, reoilin getc time to get this fixed. Thanks Skymaster!

The first time my Skymaster struts leak, they get springs. Forget the oil.
