Radio System FAQ

I want to use the 9Z's FMC functions to set up fuel mixture on my giant scale race plane so I can adjust the high-speed mixture on the left slider. Also, I want the throttle cut to dump the fuel mixture servo to wide open which releases all pressure in the tank and bring my engine up to 1/2 throttle to burn off all fuel immediately. Can it do that?

Absolutely! First, lets do the FMC functions, then we'll work with the throttle cut function to get what you need.

Model # = #10 (has preset curve)FMC servo = ch 8Throttle = ch 8
Activate fuel mixture.From Model Menu select FMC and activate.P D F F N R
Set up fuel mixture.From Condition Menu select FMC.O D L
Option: change to UNMIXED. This will cause the mixture servo to move based on throttle stick position regardless of curves, mixes, etc.A G (not needed in this example)
Adjust curve as needed.R to change point.
B then E-M to set point.
Option: Go to Rate setting and adjust amount of effect the channel 8 control (right slider default) has over the mixture at high speed (51-100%) or low speed (0-49%).O C. 51%+ means channel 8 control affects the mixture above 1/2 throttle. The farther from 50% the larger the effect. Set to 100% for now for maximum adjustability.
Option: adjust acceleration and deceleration settings (higher settings means mixture overcompensation is more pronounced. 0 = no acceleration/deceleration.Q (F-M) Ex: 0%.
P (F-M) Ex: 0%.

Set up throttle cut function.Open CUT in Model menu and activate.P C F A F
Set throttle % to -100 to move throttle as far as possible TOWARD 1/2 stick (opposite of normal throttle cut setup per customer's request.)C E M

Throttle movement is still not enough to burn off leftover fuel quickly.
Use a pmix to offset throttle closer to half stick.From condition menu open PMIX.O B I
