while I'm not at all familiar with this planes evolution all the dirty birdy's I've ever seen had a tall thin fuse...not a box type.
I looked at the bridi models on that classic pattern planes site (trentonrcflyers) and they all seemed to have a different stab, shorter coupled, etc.

in any case thank you so much for the info.

the motor is a super tigre blue head.

by the way the plane flies like a brick compared to my minare.
I remember it not wanting to pull out of an outside loop and having to roll it over to save it's butt.
Not sure if it's heavy or if the motor's tired or what.

thanks again for the info!
