Very critical. The most critical is your C.G. Next critical is your gross weight. With 70 hp your gross weight is extremely high. I'd agree with Mark saying you basically have a single place KR. To that you're adding high altitude takeoffs. When Mark and I flew my KR to Oshkosh we were pushing 1300 pounds, my licensed gross. We were pushing the aft C.G. and it's not fun. I have an 0-200 but even so the performance suffered. The more critical part was the C.G. It took an amazingly long time to get the tail up on takeoff and the handling was less than ideal. To make things even more exciting we had a gusting crosswind at our fuel stop. The KR structure is very strong but, in my opinion, anyone looking to fly the KR at 1000 pounds or more needs 100+ hp and the C.G. is CRITICAL. Anything less and you have a marginally performing airplane that you won't enjoy flying all that much. Notice what all the heavy, high time KR's are using for power.
