I will be building my SM Hawk with the BVM upgrades. Instructions show a larger cylinder (BVM) and that the air cylinder for the main gear door has the base glued to the main fuel tank.

I would prefer to secure the end of the air cylinder to something other than the fuel cell. Has anyone tried to mount the air cylinder for the main gear door to soemthing other than the fuel tank?

Thanks,
Dave

I remember Mike McConville talking about this with I think Jason Noll.. give him a call

Dave can you post the answer on this thread or he other Hawk build thread please?

Thanks bud!

Hey,

I have Jason's Hawk. He did a great job building it, and it flys incredibly well. I looked at the main doors, and attached is a picture of it connected to the tank. Based on my experience with it so far, I think that is probably the optimal connection point.

Hope ths helps.

I too have Large Hawk and agree that this is best location for these cylinders. Don't sweat it. If you have to remove tanks trust me the removal of cylinders is the easy part. Scott

Thanks guys
I don't have the plane yet to look at geometry
Will proceed as you have suggested
Thanks
Dave

FWIW, my Hawk cylinders are mounted per Skymaster's instructions and they've been fine and I have about 20 flights on the plane.

Has anyone used servos to work the gear doors? And what size servos are needed ?
