so did you drill and insert a dowel for these horns i have the same ones both small and medium size and am planning on using them...my plan was to insert a 3/8's dowel in each surface to reinforce the balsa.......also which CF gear did you use...i will order the same....my only thought was using a wider one could interfere with the wing, i assume you just have the extra width going to the front......

i hope i can stay under 5 1/2 pounds with this extra servo set-up......
