Bought a used Quickie 1 a while back, the owner had a rotax 503 in it for a bit but was told it was way too much engine and just not the answer. So as of right now im in the middle of installing a new EH72FI Robin Subaru 28hp, ordered a redrive from Ace Aviation, should be here soon I hope.
The biggest problem Ive come across so far is designing an engine mount that works, because the engine sits so low on the firewall and with no other mounting locations besides the flat base its hard to come up with a design that allows me to build a common tube engine mount so I settled for an all aluminum mount where all the pieces are machined out of solid aluminum bar. I try to keep my pieces light, I did some calculations, the 4130 tubing mount would have been around the 5 pound mark, and with my aluminum so far im sitting at just below 7 pounds..but still have some material to remove.
I'll try to post some pictures once I have the mount completed.
If theres anybody doing something familiar Id love some feed back, no such thing as too much info and wisdom.
Thanks
