737 Thrust Reversers..... how to do it?

Kris,, do you have a picture or something?

I'm not sure what you mean when you say wired the pots in series??

Sounds very interesting.

Sure - I'll try and explain with my limited knowledge...

I'm using iocards and SIOC. With an analog axis input the software converts the resistance of the potentiometer into the offset value for FSUIPC.

Connecting the 2 potentiometers in series like I have means that the input sees a total resistance of 14.7k (instead of separate 10k and 4.7k). When I pull the throttle slider to idle it closes and offers no resistance, but the reverser rotary is still fully open and showing a resistance of 4.7k. This is the idle point on FSUIPC.

When I turn the reverser pot the resistance drops to 0 ohms, which sends the reverse range to FSUIPC for proportional reverse thrust. It works perfectly!!! Hope that's clear.

Speaking of thrust reversers...

I am having a time with trying to get my throttle levers (especially reversers) designed for the LJ45. Even with the scale 1:1 drawings, it's a very tight fit and I am hoping to find a better way to link the reverser thru the main lever handle. If anyone has any info on how to connect these jokers, Im all ears. Ive tried extremely stiff (guitar) wire connected in the bottom of the rev. lever and running down between the layers of the main lever in a tight channel, but the wire is still not stiff enough to be reliable and it's too stiff to bend where it's inserted in the rev lever.

Im thinking a more mechanical solution may be required.

I have contempleted a roller switch, but I really want proportional rev thrust.

Doesn't do much good to worry about proportional rev thrust if the sims don't model it well. Just my opinion. I have already been doen this road with old real 737 throttle i had. It slowed the same whether it was idle reverse or full reverse so i just put a microswitch on it and called it a day.

From my point of view, the sim that I'm currently building is going to last me a while, not just for the current software that doesn't model the reversers well (it better had, the amount of time I'm putting in!) In a few years there will be a software version that models everything perfectly, and my sim will be waiting just to plug in!
