Default RE: BRIO Electric 10-size

I check my wreckage last night and my elevator halfs are stiff and connected well...

The elevator servo is located on the right side pushing that side elevator, so the theory is correct that a somewhat floppy elevator would cause the snaping issue.

In rethinking what happened in my crash, I was pulling easy on the downline, and I remember not getting any response intitally. Thinking from experience not to pull hard I eased off the elevator as I went to almost full power then started the pull again. I was on low rates and I didn't pull the stick all the way, I was easy on it.

I am thinking it might of been some kind of a high speed stall at first because of the intial lack of response.... at this point I said out loud to a friend standing by me, oh, no it's going to snap.

the snap started with the nose down, after the first snap it basiclly leveled off then snaped once or twice more before it hit zero altitude. the snaps where super quick and I do remember releasing all the elevator as it leveled off, but it was still snap rolling....

the Cap model I mentioned in my other post snaps the same way, it's got split elevator pushrods, super stiff. hard balsa flying surfaces no floppy halfs... it's over weight and a rear cg position. I tried adding "differential" to the elevator halfs, trying to lesson the amount of throw on the right side half beyond 1/2 stick, but that didn't help either.

the cool thing about the cap is it does all kind of cool lomcevaks type snaps and you can recover from them, it might snap but you can stop it before it goes beyond 90° in roll. And the snap is totaly predictable. I have been flying this model on and off for 10 years... it's a pitty that I didn't even get 10 flights on the brio....

I think if the brio was much lighter than 32 oz +- it would be a much better plane.

good luck guys and be carefull, I am not the only one that has lost a mini brio....
