Phil,
I didn't say the Robin was a similar price, only that the lower powered models are the same class, ie. training/club use.
But the Slingby is a lovely aircraft with very good manners. I also tried to abuse it to see if it would bite but it couldn't be made to do anything which I didn't expect or recover from. Due to airspace restraints I couldn't really get high enough to accelerate some spins so was unable to test the warning in the handbook that 'if proper spin recovery technique is not used then an accelerated spin may develop which may take up to 5 turns to recover'.
But I did get it to flick out of a few manouvres, drop wings occasionally and do a couple of normal spins. Nothing in any way unusual.
