I just got my GV1 this week and I have been reading that its only a matter of time for the sensor to fail due to vibrations.

Now, I have been thinking of creating my own mount and place it on the frame of my bird instead of the engine. I am sure the vibrations will be less and that will prolong the life of the sensor.

Your thoughts.....

I think the most important is to have the right material.

Steel (as used with the GV1) transmits engine vibration through to the sensor causing mechanical failure of the sensor.

Fibreglass (as used for printed circuit boards) absorbs some of the vibration energy and works well as a sensor bracket. Maybe that's why it's used in the TJ range.

I've integrated the sensor and governor on one PCB (see pictures in my gallery) and it works really well. Simply solder in the sensor, add a drop of epoxy, and never worry about the sensor again. Before that I had a fibreglass bracket to mount the GV1 sensor on, and flew about 500 tanks without a failure.

I don't want to mount it on the engine. I was thinking of getting alluminium and bent it the way I like and mount it on the side frame directly.

It'll be tricky to line up the sensor. The engine will have to be bolted in before you can bolt on the sensor, and everytime you want to take out the engine you will have to remove the sensor first. Not very user friendly.

Bolting onto the engine is just so much easier.

I drilled a couple holes in my engine mount and mounted it there instead of to the lugs for what that was worth. I also attached the sensor to the bracket with foam double-sided tape, then heat shrink over that for some vibration isolation.

What about the material?

Some people use plastic. Other carbon and I've seen one from plywood!

I created one from Carbon from a small piece I had laying arround.

Looks good and I am sure it has less vibrations than metal.

Its also lighter
