Thank you for the picture. I love the big slot as it means no cutting and balancing no matter which prop I use. No one will see it once it's turning anyways. Heck, I'll just pretend that they are cooling holes. Those TruTurn guys want $100 for big cooling holes cut into their spinners!

BTW, I couldn't risk not getting a silver one and put my money down. Rob at ADChobbystore is being kind enough to hold it for awhile until I will be back to receive it.

There are two holes for servos. Both in the same spot. Presumably for dual elevator servos, though you could probably use on for a rudder push-pull. I'm not exactly sure where the linkages line up. The servo is below the stab itself IIRC with the linkage above the servo.

I've got a heavy motor as well, the Motrolfly 5320, which is 22.5 ounces with x-mount and prop adapter. Running a BEC-pro on the firewall, HV110 on the side of the motorbox. So pretty much everything is out on the nose for me.
No published CG for this thing yet, but I can stick my wings on tonight and see where it balances at. I haven't flown it yet, waiting on the weather/weekend.
From some of what I read though some people with the A50-12L were shoving packs pretty far forwards, so I'm not anticipating a problem with my setup...

is the recommended setup to use pull pull for rudder when using 8S setup? I would prefer to use push/pull on rudder if possible.

yea from what im reading and guessing this airframe will take some horses up front and still balance well with packs in the good spots on the tray.I cant wait till you fly yours i wanna hear how it comes out balance wise.I'm wondering how a 4325 8s 4000 setup would balance too.

wow that is alot of weight up front

my old man got an email from KM saying CG at 5.25" if i recall. i need to reread to double check though

I'm very curious about how it'll balance with a 4325 too. I'm going to order a 5320, but I may throw that in my 72" SC as it could really use the weight up front with my 8s 3800 set up.

ya, CG at 5.25" from the leading edge at the wing root. This is how Joe is flying it, it's a little ahead of neutral as far as I know.


as for putting the rudder servo in the tail... the plane is short in the nose, and the main area is shortened for gas setups with the extender box. In general I think it will be easier to balance properly with the pull-pull set up. The electric setups so far, they've balanced well, but the packs are forward and they have pull-pull. outside of that, I don't have any other data. I'd go pull-pull maybe if you like neutral setups, but then again, slide the packs back and it will be neutral or tail heavy with the pull-pull. Even with it balancing slightly ahead of neutral, the elevator on this machine is a beast.

another thing that one can do is build the plane and do everything everything ready to fly but the rudder servo... then sit it in the pull-pull location and balance the plane... see how it goes. tape it to the plane down at the tail, and see if you can balance it.

but in general, pull-pull will balance the Edge easier and is still a very positive way of actuating the rudder.

Quick question;

A friend of mine thinks I need to run my Savox SC-1258TG's from a single A123. Do you think 6.6 volts would hurt? I have a WR BEC that I may solder into the system instead at a steady & crisp 6.0 volts.

Opinions welcomed,

2s a 123 he means im pretty sure.they have nominal voltage of about 6.6 volts

I can power a servo up on 6.6v, my Edge still needs some more love before it's flying for me to actually fly them that way (I had to get some foamies made for this weekend). but doing a search, some heli dudes are running them on 6.6v for their cyclic, so apparently they can stand the voltage... will need to confirm the load we put on them though.
