I have noticed in my cockpit SRS, that if the powerbox display screen during take off shows the frame loss etc, instead of the voltage, then the gears wont operate. However, if the display screen is on the original voltage page, then all works as per plan. You may want to see what the screen display was during your flight when the gears failed. In my case, the gears did not go up at all. So maybe your problem is something else.

Hi Guys,
Not happy today.....my second powerbox cockpit failed today. The gear door sequencer failed yet again on a second model and did not deploy the gear when I flicked the gear switch. This ended in a poor belly landing which damaged the fuselage on my SM F4.....not happy. Air system was pressurised but display and door sequencer on the cockpit was frozen. Could not even access the receiver data screen to examine for fades etc. Only power cycling the thing made a difference and then it resumed normal function....until next time.
I have owned two of these units in two deparate models ( a SM F18F and the F4) and both have had failures with the gear door sequencer....that's a 100% failure rate. The last one took only 3.5 flights to fail, the first less than five flights and the regulator malfunctions triggered that failure. No regulator malfunction on this one today, just loss of sequencer function.
There has to be a software problem with these units. I will contact my local supplier and see what happens....not happy!
Craig.
