I feel fortunate to have come across a unstarted series 5 kit, with the speedster mods and wing. I am coming from heavier aircraft so this will be my first light weight build. A IO240 is also available, but being the speedster version I am concerned about the extra weight, I am trying to decide whether I should build it as is, trade the I/O 240 off for a 914uls, or possibly buy the STI wing. Of course the easiest approach is to build it as is, a series 5 speedster with that I/O 240 I’m sure it would be a beautiful plane. I would love to hear the opinions from you guys with tons of experience.
