Heya, quick question on wiring. I have a brushless main and esc. Also a HH gyro. Got a 2nd ESC and brusless for the tail. The HH plugs into the RX on rudder. The ESC 3 control wire plugs into the Gyro. Do I need to disable the red middle power wire? When I do unlplug it, the Gyro gets no power (not powered through the rx connection I guess.

My questions are...
Do I need the mixer anymore or can I just use the RX?
Do I need to disable the pin from the 2nd tail esc? If so, where would the HH get power?
If I remove the mixer 3-in-1... how will the RX be getting powered? Should I re-enable the red power connector on my main motor's esc to power the RX since it's not connected to the battery anymore?

Basically just need a wiring diagram or what-not so I don't end up frying something. =P

Thanks
Matt

Do I need the mixer anymore or can I just use the RX?
-you don't need a mixer as long as you use hh mode on your gyro. the mixer is for rate mode, and it acts like the revo curve on a programmable tx. to state the obvious, revo is not used with hh either.

Do I need to disable the pin from the 2nd tail esc? If so, where would the HH get power?
-Yes. you should never use 2 bec's on the same circuit, and most ppl say it's best to use the main esc since the gyro can cause interference with the tail bec. the hh gyro should get power from the rx, which should be getting power from your main motor esc. make sure the red wire for the main motor esc is plugged in to the rx to power everything else. if your gyro is still unpowered, make sure your gyro's red wire is plugged in to the rx too.

If I remove the mixer 3-in-1... how will the RX be getting powered? Should I re-enable the red power connector on my main motor's esc to power the RX since it's not connected to the battery anymore?
-already answered above; yes, reconnect the red wire to your main motor's esc.

sorry i have no wiring diagram to offer, but hopefully these answers should get you through it. have fun with it! btw, what motor/esc/prop/gearing are you going with?

Awesome thanks!! You answered exactly what I needed to know.

Right now I'm going to try with a phoenix10 esc and Feigao 30mm (I think) DD setup. I'm going to start with the prop that comes with the DD kit ... a 4540 or something like that. Slightly bigger than a 4040. Sorry I'm new to the prop sizing terminology. I'll post how things go when I get it all figured out. =)

Thanks for the info!!

np, it's always nice when ppl make a clear list of questions like you did. it makes giving the right advice straightforward.

you're right btw, those long can feigao's are 12x30mm. the one ppl use for DD is the 4100kV version. there are 2 other winds available i believe, and the middle one is the 5300kV that is used for gear drive tails.

about the prop: a 4540 is way too much prop. most ppl running the 4100kV motor in DD go with a 3030 prop. i ran a 4030 with my 5300kV in DD and it was smoking hot (ended up using a 3020 to keep it cool). a 4100kV will stay cooler, but i think even a 4030 might still be too much prop.

fyi, r/c propeller numerology goes like this:
4540 prop -> ABCD -> A=4,B=5,C=4,D=0
A.B = diameter (in inches) = 4.5"
C.D = pitch (inches of forward travel from one full rotation at zero angle of attack) = 4.0"

good luck, and enjoy flying with your new tail!
