Hi Colin & Mark,
Thank you for sharing the information. I was really hoping that someone would
confirm these figures as being accurate as that would have made the Type 4 VW
the ideal engine in this case.
The type 4 VW, with a belt reduction, is currently used extensively in a J3 Cub
look alike microlight manufactured in our country. Danny Livingstone, also a
KR2S builder, has one at their flying club in Parys. They gave up their
Cherokee and now use this aircraft for training. He commended on the excellent
takeoff and climb performance with two aboard - and they are situated close to
5000ft altitude.
I am after the lowest empty weight possible (just something that I WANT to do)
and 105 HP at 150# sounded inviting.
The recent report of another newly completed KRII in the 450# range rekindled
my interest in completing my project and I have started building in all earnest
again.
Regards,
Hennie
