In any event the consensus seems to be that this is the first anyone
within the KR community has heard of a spar failure in the center
section. So far that makes it an anomaly, with no indication of any sort
of trend. It's been said that "a pilot can pull the wings off any

Very doubtful that it was a spar failure. Probably a lot of aerodynamic

of a tip(possibly taking a piece of the outer wing with it) could get
ugly fast.

I'm looking at the 80kw motor from Freerchobby & an Orion controller
Freerchobby make sever motors for about 15kw up to 100 kw. The only problem
is you have to feed them, a big battery pack, I hope to use an 80kw motor,
have to sort out new wt & balance, from a 150 lb VW to an 30 lb motor , but

Hi robin,
You have me really rethinking my approach.
Does the website freerchobby have motors greater than 25 KW.
45 KW seems to be the magic numbers from my calculations to get
a KR-2 aloft. and buz around.
Any comment

Okay, Let's jog some memories. I know the engine of choice for a Kr-2

My question is were there any flights made with lower Hp engines?
My real question is - what is the absolutely lowest Hp engine that will

the ground?

This is how Piper handled it on the PA22 aircraft.

Thank you very much! I wonder how do I fix the aluminium strip or composite
strip to the wings, screws/glue... Any close photos.
Again thanks,
