My second irvine 36 is on the way from Sheldons Hobby, Engine #1 has a head that AJ was kind enough to make for for me. I was looking at the glow heads that came off the irvine Q40 and the irvine 36 appear the same, thus the davis
diesel head that fits the Q40 and irvine 40D appears at this point should work on the irvine 36 will let you know when the 36 shows up next week this little bugger cranks 9900 on graupner 11x7 and same on top flite 12x6 power point prop
BUMMER tried the 40 davis head perfect fit EXCEPT radius of bolt pattern off about .040 so much for that idea , holes could be egged
out but I do not consider that an option. Will check with davis and see if he can do with correct radius martin
