Switchs, a lesson learned.
Just because something is new does not mean it is good. I bought a new GP Space Walker and wanted to make sure everything was 1st class on it as I had lost one due to bad GP CA hinges separating.
Anyway, I had a new Magnum 4 cycle engine, new Hitec servos, Polk Hobbys Seeker 6 receiver, new battery pack and a new MPi 3470 charge switch.
The switch, upon checking it out after the crash, would not stay on if it was touched in anyway. With the engine viberation and normal flight "bouncing", it is no wonder this unit failed.
Be very sure to check the simplest components, never trust anything, even a simple on/off switch. [8D]

RE: Switchs, a lesson learned.
A few years back, Futaba had some defective switches, the were "soggy"
and didn't have a crisp snap to the on position. After losing a plane with
them, I threw out the remaining three new ones I had and bought the
Cermark switches.
You can tell....when you lose control of the plane, and you can't throttle
back....you've lost power to the receiver.....yard dart time, straight in. [

RE: Switchs, a lesson learned.
I'm surprised that you had trouble with the MPI switch. I've only read good things about them.
Since I have them in several models, I'll check them out thouroghly.
Thanks for your comments.

RE: Switchs, a lesson learned.
When fitting new parts to anything. The greatest possibility of a failure occurrs when the part is brand new and further down the track when it reaches wear out. It's called the bathtub reliability scale. There has been a bunch of times that I have fitted a new replacement part to an aircraft only to have it fail straight away.

RE: Switchs, a lesson learned.
I had my very first plane, my trainer, fly away on like the third night of training while on a buddy box. The story ended well but until it was found I thought four hundred bucks of new stuff had just flown off. The switch had not stayed in position. No more cheap switches for me.
I am surprised that the MAXX Products switch failed. I have a few of those on my planes.

RE: Switchs, a lesson learned.
I HATE to test fly a NEW bird with anything NEW on it like radio, engine, servos, etc. You never know ..... new doesn't always mean it works! So guess who is about the test fly a new plane (Seagull Laser 200 with a new radio (JR 9303)? Your first two guesses don't count
