Hi Jeff,
I don't have one but there are at least 3 at my club, one of which is flown by one of the UK's top show pilots. From the comments that have been made its possibly (I must be careful here you understand) better than the Synergy 90, more robust in construction and flys just as well. Engines used are YS 90, 110 and a SC FS120
It is a very good value for money model, I would certainly buy one if I had room for it (I have enough other similar models) Hope this helps.
