I didnt even intend links, just copy pasted the article, and it is such a COOL history, I thought I'd post it.
The revolutionary takeaways were: small size novel construction very high strength inexpensive across the board retracts! speed and performance as well as economy The later areas for improvement: dynel cracking (easy update new projects to fiberglass) vw bug engine reliability (cracks crank, heads, seems usually resolved) landing gear bolt breakage (easy fix) just a few random memories from decades ago, it seems co-developer stu robinson kept a low profile. also RR developed 3-blade ground adjustable composite props that developed cracking at the base of the blade. But a VERY cool look! I'd like to have 3 blades for looks and ground clearance if I ever get my project off the ground, and tri-retracts since I dont have tailwheel time. oh and people questioned the strength of the WAF's until it became abundantly apparent they simply do not fail! the few turbo projects were really performing well. IIRC they used small normalizing rayjay turbocharger, but these I think exacerbated the vw issues. I am looking possibly at d-motor for mine, and wonder if a light normalizing turbo option could apply... > That link should read > http://aerofoilengineering.com/KR/sportaviation/Kr73-1.HTM . > _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
