ORIGINAL:
The new ones have to where you can mount the tank further back which means you might need a pump for the 160.
Oh, control horns need to be 6-32 if you don't get Tom's pack.
I have a couple clarifications.
The new planes have two tank mounts, one up close right behind the engine, theother is under the wing tube. You may use either one. The one farther back is meant for engines that have a pump, either glow or gas. Keep in mind that Walbro carbs have a built-in pump so any gas engine will be able to use the rear mount.
Putting the tank back on the CG means the CG does not change as you burn off fuel, a definite benefit.
Also we had some complaints about the hardpoint holes being drilled on odd angles. I reported this to the builder who went back and redrilled them to be sure they are straight and square.
The by-product of this is thye plane will require 8-32 studs for the larger holes, so in the hardware kits we'll be supplying the same horn kits that come with the 28% planes.
