BrendAn Posted February 2 Posted February 2 (edited) wondering if anyone on here would know if a 912 engine mount for a gazelle or kitfox would fit an avid flyer. they are all variations of the same basic design. chasing one for an avid flyer. currently has a subiru which the owner wants to change out for a 912.

Nev This one came from America fitted with a Stratos aviation Subaru ea81. He is hoping to fit a 912 and use the suby in a big airboat he has. Probably a good place for it after all the Subaru talk lately. Although I don't think ea 81 s give much trouble. Edited February 2 by BrendAn 1
Thruster88 Posted February 2 Posted February 2 EA81 is the brumby engine, simple push rod engine. They don't make enough power to hurt themselves. 1 1 1
skippydiesel Posted February 2 Posted February 2 (edited) I don't have any experience of the Avid Flyer or the clones you have mentioned. I do have experince of 912ULS mounted in a ATEC Zephyr & Sonex Legacy . Rotax make an engine Ring Mount that must be connected to the firewall frame/mount via 4 vibration (rubber) isoltaters. Two frames. This is the best & most costly arrangement. Good second hand ones do come up for sale. Talented people are know to make their own . The Zephyr used an ATEC factor mount, The engine frame, mounted to 4 points on the engine via rubber vibration isolators, went back to the firewall ie one frame. Worked well. The Legacy has Rotax to Arovee engine mount adapter - two double rails, separated by 4 rubber isolators. This is what I think is called a "bed mount". It connected to the bottom of the engine. Workable but not ideal for the Rotax, which generates considerable rotational torque, producing significant movement, particularly on shutdown/start up. Sonex has recently developed a firewall Ring Mount connection for the Rotax engine Ring Mount (purchase from Rotax) - a much better system for the 912. 😈 Edited February 2 by skippydiesel 1
