Guys,

Horst from JetTronics will have a solution for his valves and sequencer in about a week's time. It's a pulse amplifier and should cost around 6EUR to 10EUR

Here is the mail I originally received....

Hello Mark,

excuse the delay, I was in vacation and could receive but not answer
my mails.

I know about the Problem and have made a pulse amplifier for the
sequencer which is also good for all servos and other equipment like power
boxes and so on. I have myself 5 receivers and do not operate the most
important servos like elevator, ailerons, ruder, flaps and throttle without
this pulse amplifier even the servos work on the test bench, they can fail due
to temperature or supply voltage changes during flight, because
everything is right on the edge with this small pulse amplitude.
So I really recommend to use an amplifier, even the servo works.

If you use the sequencer with amplifier you will not have to have
amplifiers for the valves. I have not checked the valves directly on the
receiver yet.

Best regards
Horst

As I am running my valves into a sequencer and then into my PowerBox Royal I won't be affected but those with JetTronics valves straight into the RX should get one of these amplifiers .

Rgds,
Mark
