Hi
Most of us that build them took a long time deciding which RV to build and went for the 4 because its the best handling after the 3, can offer two seats and is an all round great aeroplane. We know ours intimately, inside and out and dont want to part with them.
Strange I dont have this passion over the 9 I built.....no not strange at all!!!
