I was actually thinkin that i shoulda got a .40 instead of a .46... I dont think i could get a 10 oz. to fit very well without some serious modifying of my fuse, and i dont wanna do that. And, with a .46, i'll probly be going much faster than i would have to without realising it, and a 40 wouldnt let me do that... oh well, too late now... and its only .06 of a diff.
I have the PT40 and while trying to troubleshoot an engine problem, I tried to put a 10 oz. tank in it. It would not fit without binding the throttle and nose gear pushrods. The 8 oz. tank fits nicely between them.
The other thing that you should consider during the build is relocating the steering arm and the pushrod if you have an engine with a remote needlevalve that mounts to the backplate of the engine. The valve will limit the throw of the steering arm if built according to the plans. I'm looking at lowering the pushrod about an inch and connecting the steering arm to the nose gear in the middle of the engine mount so that they connect below the needlevalve. Having this information before I built the plane would have saved me an extra hole though the firewall. Hope this helps.
