I have a UMS Technologies hydraulic landing gear system on my P-40 that has a timer switch on it that is adjustable for 10 - 20 seconds. It has gone bad and is no longer functioning. The only place I have been able to find one is at UMS Technologies in India. I have found the complete system at Hobby King, however, I did not want to purchase the whole system for $118.00. Has anyone else run across this problem? and if so, how can it be rectified? Is there anyone who has been able to find a similar switch as I am not having any luck myself? Any suggestions are welcome. Thanks!
