avid flyer

[BrendAn]

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.

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.

EA81 is the brumby engine, simple push rod engine. They don't make enough power to hurt themselves.

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.
