Variations:
The above setup eliminates "hot starts" that result from the Flight Mode switch. It does not prevent you from starting when the throttle stick is up. There is a mix that will prevent ALL hot starts, even throttle stick based hot starts. The cost is that the RPM limiter will not work in "Normal". To use this variant, change MIX1 as follows:
Note that throttle trim DOES contribute to the "tipover". Again, you can see this on the monitor screen. This prevents hot starts that would be caused by the trim being all the way up, or similar. Note that I personally DO NOT FLY this variant... it is for the truly paranoid!

Caution:
DO NOT use the RPM Limiter during break-in of your engine! It can "hide" behaviors that you should be seeing as the engine leans out and similar. Therefore, DO NOT use the above mixes (or any other form of limiter) until you have a good, working, fully broken in setup that flies on throttle curves.

Great work! Needs a sticky fo-sho! You don't know how long I played with the mixes to try and acheive this affect.
Questions: So you're running on the rpm limiter in Norm mode but only above 25% throttle right? Are you getting the glow to lite when switching into hold from any flight mode? I will tach the head upon trying this setup but are these %'s actually what you're using? Could you hook us up with the real %'s if these are listed as examples? Also, which rates do we adjust to change the set HS's for N, IDL's 1 & 2?

So, a "Truth Table" for the GEAR and FM switches looks like this: Code:
Gear Up Gear Down Normal Limit On, Glow Off Limit off, Glow On FM1 Limit On, Glow Off Limit off, Glow Off FM2 Limit On, Glow Off Limit off, Glow Off Also note that Switch Down always= No Limit, Up = Limit. Easy to remember. I don't like starting in hold because you have no Throttle Trim when in Hold on a DX7. Quote:

Calculations are shown in each mixer, but here's a rephrase for clarity: For Mix1, it's -x where 100-x=the rate. For Mix2, it is the same... just because of the DX7, Mix2 stays active as Mix3 kicks in, so Mix3 has to be different. Assuming you want higher headspeed in FM2, Mix3 becomes the % to add to Mix2. And, yeah, my examples are "real" for the T700.

DX7 + AR7100R + Switchglow
Hi Danal Estes, thanks for the info . I have very carefully followed your steps in setting up the mixes , but the Switch Glo goes off when you power up the heli with the gear switch in the up or down position. This was happening even before I tried the mixes. Anyone have any thoughts. I did calibrate the rev limiter and it turn on at 25% throttle. I have not used the limiter or the Switch Glo yet. Only 7 tanks throw theYS so far.

When you say "goes off", do you mean runs and then quits? Or, do you mean "won't stay enabled?" SGs time out after 10 seconds. Use the servo monitor screen and look at the GEAR channel. With all switches back/away, it should be at about 75% (to the right of the mid mark). Switching only the GEAR switch down should cause it to move to the left, all the way slightly past the normal endpoint, about -120%. Let me know what's happening on that screen.

Aha! I have mine on the 8v. I know the 8V side does not put out "memorized at bind" positions (for example, the 8V JR8717 servos do not init until the TX links up). I'm not as sure about the 5V side of this RX. It may put out "memorized at bind" like all other Spek/JR receivers. Therefore, May need to re-bind with the GEAR switch down.
Just curious: After heli power up... and TX link up... do the switches then work as expected? Sounds like not, from what you said. If they still don't work... then this isn't a bind issue. Let me know what the monitor screen says.

Nice write up Danal.... this needs to be a stick but where? It's not just a Trex700 thing. If you like I can move it to my forum where more people will find it? Or the DX radio forum?
Let me know, Bob

OK so... I'm using the SG plugged into the 5V slot and copied your mixes into my radio to a "T". According to the servo monitor, my gear channel moves past the far right line when in Norm and the SG ignites as it should. My problem is that the SG will also ignite when in IDL 1 or 2 modes so I can still get a hot start.
If I drop the voltage (using 3-4 diodes) of the 8V gear channel and put the SG there will this alleviate my problem?

I built a drop down regulator to drop the 8V gear output down to 6V and plugged the SG into the 8V gear channel. It changed nothing... I can still ignite the SG in any mode by flipping the gear switch down. I tried rebinding with gear switch up and down on both voltages to no avail.
Also, upon further inspection of the servo monitor, the gear slider doesn't change with different FM's. Could use some help with this Danal... What am I doing wrong?

Meanwhile: Ensure that Mix2 RATE: numbers are BOTH negative (minus). Upper number should be -20, lower -100. On the "PROG.MIX2" page, ensure that when physical FM switch is in "normal", that it shows "OFF", and when clicked up to 1 or 2 that it shows "ON". Also, examine the "SERVO MONITOR" screen. When in FM-Normal, clicking gear switch should move the gear channel from one side to the other. When in FM1 or 2, clicking gear switch should move gear channel from the negative side to 0 (middle). Let me know what those screens show. P.S. Port/Voltage will make no difference, as you discovered.

P.S. I've already gotten a call from the folks who found my radio. Thanks Weldon, Micheal, and Ron.
