One of the differences between the kit builts and the R22 is range & endurance. The 22 cruises at 80 kts for 3 hours for a 340nm range while the kits are more like 60kts for 2 hours. I looked long & hard at both the baby belle & the Exec90 ten years ago & found that for the same money I could get a good used R22. A thousand hours later I've flown it to all Australian states & generally had a ball. I will now put a saucepan on my head & duck under the desk while the kit built guys open fire. Cheers.
