Where does the time to? I spent liKe three hours adding in some balsa fairing to better blend in around the canopy, some hard points at the stab and wings and spackling in a dozen different places to make everything nice and smooth This is the tedious part of every build but essential for the final covering to be perfect.
So probably another night to final fill and sand, then everything will be ready to cover barring my denting something again.
A big thanks to some wonderful guys who sent me some needed items...

Re: Carden PRO Built by Lee

Basically I want redundancy if one servo or battery packs it in, and this allows for a whole side to go dead and still have what I need to bring it home. The aileron will be oposite of the rudder/elevator. Comments?

Talking Re: Carden PRO Built by Lee

Lee:

If you think about it carefully, you are using Futaba. No need for any kind of redundancy as with all Futaba equipment, it will never let you down.


Are you on for breakfast tomorrow morning with the gang? I want to drop over to see your build progress after that.

That's if the shorted servo or battery doesn't fry the Rx!!... since it's all connected to the same Rx, one could argue that there's no added redundancy...

IMHO, it still seems too complicated and running two cables all the way back to the tail kinda defeats one of the purposes of SBUS
.
.
What about putting the Rx in the tail and use the regular servo ports for an elevator and rudder servo and the SBUS connection for the other elevator and rudder and then just run a single cable to the front for ailerons, throttle and ignition kill?... you get the same as what you've drawn and only have one cable down the tail (cleaner, less weight).

BTW... just a suggestion.... can't go wrong any way you slice or dice it with SBUS

Re: Carden PRO Built by Lee

Brendan can't make breakfast but you can come over any time!

The problem Trev are the hitec servos on rudder and Im not sure the Durant receiver will fit Futaba servos. Also I would have to change the servo arms on the Durant blades and that would probably destroy them so Hitec it is.
I have never had a receiver die on me but have had batteries, switches and servos pack it in so a little redundancy for a plane that will see (hopefully) hundreds of flights negates the problem with two wires running forward.
This will still be a super clean install and should have very little visible when I set things up.

Interesting idea but you have to make sure that the batteries on the right and left have the same voltage or the servos will run a different speed no voltage regulators are the same

Ahhh... great point Lee!!! I once changed out the horns on a Durant and it was a nightmare!!! Yep - you're definitely best to stick with that route then!!!

Lee - what Servos are you going with on the elevators and ailerons???

Hey Helmut, nice to hear from you! Yes I thought of that and I will be buying four of the same liIon packs and will balance charge them. I used some LCD voltmeters on my JTech Extra plugged into my SmartFly turbo and really liked being able to see the voltages for both packs at all times and will do the same here.
Also the drain should be comparable except for the throttle servo on one side and I can maybe run that off the receiver but we'll see.
For servos Trev, I'm thinking of BLS 172 all around for total overkill, but only using two on ailerons so not such a hit in the old wallet!!
