G'day Paul,
I built a Cougar. I heard about the nose-leg issues and have no such issues due to the extra struts that connect the leg to the engine frame. Whilst I haven't flown a Sierra, I chose the Cougar after having flown all sorts of small aircraft. It is fantastic and solid as. I also wanted a four seater.
The build is pretty intense as there is little provided pre-made (mostly some fibreglass bits like winglets, the bubble canopy and the solid steel central frame. The joy in the construction was made much easier by Garry's guidance throughout and his unending patience. Even with his move to NZ, he is still only an email away and I'm sure that if Garry has entrusted his work top Ray, then he will also be a great asset.
In the end, the proof is in the pudding.
Garry has designed a fantastic aircraft. And I reckon when you look at bang for bucks, you won't be disappointed.
Garry (Hardingham...not Morgan)
