Hi Randy41
I had a look at the senior as you suggested the only reason I have overlooked this a/c is because towerhobbies had it listed as a .29 to .40 engine rating, unless I am reading it wrong (knowing me) =)

Sig Kadet Senior Kit .29-.40,78"
My new question is: Is engine capacity related to wingspan? Like you said 80' wingspan, and one other thing, the picture of the AFR Senior and the Kit Senior look totally different and I can only think that this due to someone covering the aircraft differently.
Thanks,
Mr.B
