you'd do better to make a flat plate surface and use the servo to move it. the servo one it's own wont have enough area.


good news...
found my upthrust was comming from my T-nuts poking through the firewall and pushing the mount out. i counter sunk the back of the mount and put it back on. got myself the right angle.
i've got the cowl on ok but the gap at the front is more than i'd like. but.. i'm going with the fact the firewall is right and get the cowl best i can. Much happier with the exhause exit this time, shame about the engine head exit, but it does seem to make getting it on and off easier.

I've got the tank in, did it a bit different this time. it's higher up with the top of the tank in the turtle deck, the bottom sits on a little ledge i made which comes from the top of the cut out on F2. this should give me failery constant fuel supply for the whole flight. not that i had trouble last time, but i do have more room for the Ni-cad under the tank if required.
Fuel proofing is still tricky once built, forgot my own advice to do that before you add the turtle deck and bottom balsa caps. Wondering if i can pour my fuel proofer into a spray bottle and do it that way
I can see light at the end of the tunnel, just the balsa lock to go on now and it's ready to cover.
