Have heard great things about the RV range, however noticing what can be done on a Rotax 80/100hp with a composite airframe (145KTAS/1000nm+) the RVs get second place according to a certain UK aviation magazine - and I tend to agree.
Having said that, the RVs have distinct advantages - frog (pop rivet rivet - get it?
) construction, some of them are aerobatic (+6/-3), and the RV4 (I think) can be converted into the Harmon Rocket, a rather fast & manouverable aerobat with better capabilities. Currently being evaluated by the PFA I believe.
Personally I think the great thing about homebuilds are the ability to customise and the ease of finance - you only pay for what you're building at any one time - and cheaper maintenance is a huge benefit. Now, add the GAMI PRISM system to that and... woohoo!
