Re: Do you analyze your accidents

After some careful analyzing I found that the cause of this accident was pretty obvious. The tree clearly didn't stay still for my flyby. Lesson learned you ask? Of course next time I will try to flyby smaller trees. This should dramatically reduce the possibility of this happening again.

Re: Do you analyze your accidents

We had a tree at the west end of our approach on the north side. A lot of the pilots insisted on hitting it. So I cut it down. For the last two years they insisted on hitting the next one over. The gap in the trees is over 100 feet wide. Some guy's insist that they are smarter than the average tree.

Wait just a cotton' pickin' minute! I wasn't even flying! Ron was on the controls!

Yeah Dale, Mr. "hand the Tx off and run"! It was pretty funny though!

Merv it's a good thing your not a tree climber by trade!

I try and to figure out where/what happened, it not always easy to pin-point.

Re: Do you analyze your accidents

I think you have to ,I lost one this summer EF 110 , I fly JR so you can rule out the radio lol ,the engine kakmaster DA100 did what it does best and kak,though this was not the the cause of the crash it was more a lack in judgement ,flying a light weight high drag plane tail heavy in high wind with a motor I didn't trust,deadstick landings are no problem and in the wind I always position myself well to make a landing but I did not anticipate the plane would come to a complete stop when turned into the wind deadstick, after that there was nothing I could do ,punched the nose down but gained no forward speed ,took the elevator straight biggy new fuse on the way ,I pulled the kakmaster and installed a DLA 112 been having great luck with them. I will keep this one for calm days in the future. what I learned was no matter how long you have been flying you still have to learn some things the hard way LOL . cheers Roger

Re: Do you analyze your accidents

I think it's pretty much a requirement to investigate any incident that doesn't have an obvious explaination.

To this point, I've only had one accident that really couldn't be explained by something other than obvious, sheer stupidity. It was radio issue of some sort that locked up the servos on a new Cap 232, ending it's maiden voyage in a blaze of glory.

My post analysis showed that some of the old FM receivers I was using were possibly low-band (despite being labelled as high-band). On the bench the servos were twitchy and occasionally making quite pronounced movements. I converted to PCM and haven't had a problem since.

Re: Do you analyze your accidents

Being an engineer I'm genetically programmed to analyse everything to death! But after a lot of crashes over the past 3 years (exponentially decreasing in frequency I'm happy to report), I've realized that the RCC member whose signature says something like, "The better I learn to fly the less radio problems I have" is correct. The more experience I gain in plane construction, set up and maintenance & in dealing with unexpected situations, the more I understand that when "incidents" occur it is basically my fault due to ignorance, unintended carelessness or lack of flying expertize.

As an example, a week ago I put my everyday, all-weather e-Stik (which has 100's of flights on it) into the ground so far I had to dig out the motor with the broken propeller pieces. It happened on a vertical downline from a stall turn when I heard a whirring noise & suddenly had no up elevator. I had recently put a temporary horiz. stab/elevator made of corosplat (sic) on because the regular stab/elev was sticking. Unfortunately, I had not thought to reinforce the coro hinge with tape & it separated under the force of the attempted pull out from the vertical downline.

In another case, a series of "mystery" spins into the ground was explained by my having put JR servo arms on Hitech aileron servos not realizing they had different spline patterns. In a sharp turn the servo arms had slipped creating a a permanent up or down aileron on one wing causing the spin. For a long time I thought there was somthing wrong with my receiver - even sent it back to HH to be checked over!

I guess the main thing is to learn from mistakes & not make them more than a couple of times. For instance, today the weather was pretty good in the a.m. but by the time my flying amigos & I got together at 3 p.m. it was pretty windy & cold. Well, instead of launching my repaired Stik into the air I decided to hold off for another day as I was not sure how the repairs had affected the trim. A couple of years ago I would have gone ahead & flown & probably would have been picking up the pieces 30 seconds later.
