Crashed? Discussion and Photos > A very expensive lesson to learn - might kill myself

I take my Evo90 for a maiden flight. While still doing the fine tuning on the cyclic and rudder, I suddenly lose the aileron control. The Evo 90 tips over and goes chicken dance for half a minute before the engine quits. The damage is actually not that bad. I figure out it would be about $200-220 include a new set of 710 carbon blades. Upon close inspection of the crash, I find myself so stupid that I forget to put the screw back to all the collective servos to secure the horns in the last adjustment.

I am lucky that I do not get myself killed as the heli would have drifted uncontrollably towards me or my car. Instead, it just tips over and crash. This is a very valuable lesson to learn.

You are lucky that you had the heli for a month before it happened. I only have it for 3 mins!!

I did the same thing not long ago with my 450. I was doing a chaose 100ft up and I just lost controll I hit hold and just watched it fall........ and fall.... for like 2 sec but it seemed like forever. I hit hold soon enough that when it hit the ground the blades diddint even brake. but alot of other stuff broke.... the servo horn screws were sitting on my desk.

Seems like quite a common mistake.

I've never done it, the Futaba screws seem to be ratehr rare so I make sure they are always where I can see them!

Did it on a plane elevator servo before. Showed up at the field, buddy looked at the plane and noticed screw missing, I said I'd fix it, unloaded more stuff, took the plane up and into a stall turn and watched it go straight in thinking "damn screw".

If you can't learn to do it well, learn to enjoy doing it badly.

I've done it with a throttle servo, lucky it fell off at idle. Live and learn.

I think a new design could help- a positive lock that clips the output horn to the servo shaft- then a small tool inserted to release the clip and remove the wheel. So you need intentional action to remove the wheel, but it automatically locks when installed.

I might just go to work on this one- need a retrofittable design though...

Never, ever, ever, ever give up.

i know the feeling man. I used blue locktite rather than red on the swash of my vibe90. One of tha balls backed out leading to a blade fold......down she went. The kit was almost a total loss. It even bent the crank in the engine!

Kinda funny how a 2 cent screw can destroy a $2,000 dollar heli.

Get a life? How the hell do you fly a life?
