CAP 232 loses half of elevator.
Just had our club BBQ on saturday - about sixty people turned up for glorious weather and superb food. It really is the highlight of our clubs year. Anyway I have a CAP 232 breitling which is a gorgues plane i really love to fly; it tracks great trhough loops and looks so good in inverterd low passes. Anyway just took off on the club BBQ with all the people beghind in the pits surrounded by a wire fence did one circuit, just throttleing up and *CRACK* off comes the left had portion of the elevator! I have never seen anything like it, anyway after a (very smooth considering) circuit brought it back ito wind (i was okay aslong as i didnt bank left) and dumped it just short of our patch to a cheer from the crowd! woo!
The problem was traced back to appaulin wood selection in the elevator, its like sponge cake! and also the new prop that was fitted. I went from a 14x10 (model flew far too fast) to a new carbon 16x8. The rubbish wood and massive torque from that prop pulled off the elevator - definatly not flutter all hinges are close fitting and wasnt travelling nearly fast enough. Also the join was VERY clean though not along a glue joint as there is no residue, there also was no through brace to speak of.
Anyway the point of this post is this: after my experiences with losing half an elevator does anyone else have any similar miraculous stories? and also to point out that i always thought ARTF's with poor wood selection were bought by other people and that it never would happen to me - well i was wrong! You guys check out your wood selection!
I thought as soon as you lost a vital piece of your plane you were toast - you would be looking for all the pieces - however again i was wrong! Just shows; i love this hobby its so engaging and i read upon eveything i can but you never can stop learning!
This is 60" span powerd by a SC91 fourstoke (just purrs along) and a 16x8 carbon firbre prop (yum! cost me a weeks pay - im 16) dual conv rx 6v rx pack etc etc...
Here's some pics: will get better ones ASAP, will try and get one of grain of wood.
Anyway i welcome your ideas and comments,
Rich
