Hyjinx also suggested using a Perry pump. I'm wondering: given the way the two variants of Perry pumps work, is there really any reason to expect that they'd work for radial engines?
-tih
Thinking the vibratory pulse type may work. The radials run smoothly but the pump should still pulse I am thinking.
Still of the mindset that with proper tuning and fuel mixes it shouldn't really be a necessity anyway.
Sounds like castor will be an additive Maxam. Percentage as mentioned earlier in the thread.
Thanks for the thoughts folks, enjoying the 7-77 ums.
Almost makes me want to fire up it's first off version. I have the original Seidel made by Wolfgang on a shelf.
Haven't run it. Bought the UMS Horizon Hobby knock off for an everyday 1/4 scale airframe.
Like to come up with a 1/4 scale Steglitz for that one and keep it all German!
