RE: Excelleron 90 build in progress
I am also working on my Excelleron and it is about 90% done, but currently waiting for the YS 110 to become available again so I can use it to power this plane.
I changed the pull-pull on the elevator control horn take-off from stock to Dubro #878 (Tower Hobbies stock # LXKLV3), which helped to make the clevises lined up with hinge line.
In terms of throttle servo, I am using Hitec HS-55 micro servo, and placing it behind the firewall where the stock fuel tank should be located. The similar servo has been used in my other plane running 6V-5cell setup with good result, so this same setup is used on this plane as well.
About the landing gear, since the stock landing gear looks to have enough ground clearance for 15 inch propeller, so I am sticking with that for now.
Hopefully the engine will become available soon before the raining season arrives.
