Thanks Tom,
I went with the On-Mom switch as I don't anticipate needing camber AND landing settings anytime soon. I wanted the momentary switch to avoid the possibility of bumping the throttle switch to on and having it stay there. I like idea of a 16" carbon prop at 8000rpm shutting itself off if I'm not actively telling it to be on. :)

Hi all,
Does anyone happen to have a DigiKey part# or specs for a spring loaded toggle on an 8103?
I want to replace the gear switch on my 8103 with a spring loaded switch to control the throttle for my F5B ship.
Thanks Dan
Dan,
The stock gear switch on the 8103 is a single pole, double throw (SPDT) model. You have a couple of different options.
You can use an ON-MOM (ON or MOMENTARY), but in the case of a glider setup using the same switch (CROW or Butterfly switch), you will either lose variable camber on the flap stick or landing mode depending on the settings in the Butterfly menu.
If this works for you, then you can order a switch that looks VERY similar to the stock JR switch, but is better quality. Oh, and it won't look like a high school shop project ;-). The part number from DigiKey is CKN1143.
If you do not wish to lose the camber AND landing mode, and want to have the motor on a spring-loaded switch, then you might want to take a look at the modification that I did a bunch of years ago for the 8103 to add a launch preset for handlaunch. In this case, the switch is replaced with a three-position switch with the function ON-OFF-MOM (ON or OFF or MOMENTARY).
In the center or OFF position, you are in LANDING mode. In the ON position, you are in variable camber mode. In the MOMENTARY position you can activate a mixer for launch preset or in your case for motor ON. There is a pretty detailed set of instructions either at:
http://www.hoopesdesigns.com/ and look under "Other Goodies"
OR
http://silentflyer.org/articles/8103-mod-1.pdf
The later option gives you what you want without having to sacrifice landing and camber modes. BTW, you can also add elevator preset during "climb" by using one additional mixer.
I hope this helps.
