Fire Extinguishers and Xmitter springs

[Wayne Galligan]

OHH yesss.... just had that happen this last weekend.  I lost the rudder spring during a stall turn.  Then I had to land in 20 mph crosswind.  Very touchy with no feeling on the stick.  Had the aileron ones go out too about one month ago.   I think it has more to do with the age of the unit. My 8UA is about 8yrs old.  Plastic gets brittle with age and especially if it is expose to UV(sunlight).  All thought these little parts are shielded from the sun somewhat  I am sure there is still some exposure when left to Mother Nature.
AND of course they seem to break at the most inconvenient time...like 4 days before a contest.  I guess that's better then during a good round in a contest.

  A comment about those new springs:  I've now seen 3 transmitters break the plastic hook that holds the spring to the gimbal.  On gimbal broke twice!! first time on the plastic hook and the second on the gimbal side. Those plastic parts are nit designed for the load of the heavy duty springs.  My transmitter was one of these.  I now believe that they are a nice idea but an impractical one.
  Be warned and be ready to land with no spring center.

    Since all this talk about Li-Poly's and such, I was wondering what type and size fire extinguisher you guys would recommend for your shop.

    Second question.  I recently replaced my gimbal springs with the Radio South heavy duty springs.  The stock springs had grease on them.  Anybody know what type grease you should use on your transmitter springs?

    Thanks,
