Default Sig Citabria Build

Leaving the warbird scene for a little bit so I can start on a GA build. This will be my first Sig kit. I'm planning on converting it to electric.

I ordered the cowl from Fiberglass Specialties to make the building process a little easier.

It will be powered by a Gforce 46 with 4 standard servos and an 80 amp ESC all from Valuehobby.

I will be building this per plans so nothing special here. Just a nice, clean and fun build.

Started on the right wing. I drilled holes through the ribs and decided to go with the traditional servo mounted wings rather than the dated bell crank setup.

so far I'm enjoying this build.









Thats it for today!

I'll be along for the ride...
I have one of these kits on the shelf waiting on me...

Twp servos for the ailerons certainly simplify the set up from crafting the linkage all the way through creating differential movement.
I'll be interested to see and hear your review/opinion on the cowl from Fiberglass Specialties.

What will you be covering it with?

I'm not sure, but I did order a red spinner from Dubro for it so maybe what's depicted on the box?

Very nice. I see you added flaps too and some other wing mods.

Question: how did you make access to the battery hatch? I'm thinking of making a side hatch just after the cowl for battery access. I haven't planned it out yet until I start the fuse.

I started to write more there and stopped short.
What I meant was, what type of covering will you use? Iron on shrink film (plastic) or simulated iron on cloth or actual cloth

A little more work done on the right wing today. The A1 - A2 ribs was my least favorite part and required some angle sanding to get them to align.




A1 - A2 ribs


First time the wing was removed from the board


Aileron cut free from the wing

This is a nice choice and ends up being a nice airplane when finished, also your workmanship is excellent. I did one of these probably 40 years ago but still remember it. You will have a weird wire assembly built into the cabin front that holds the wing on. It's sure nice to see one of these being built. What type of power are you using on it? Good job BTW!

Thanks! It will be powered by a GForce 46. It's equivalent to a .46-.55 two stroke with a 4s.

On to the left wing. I won't bore you with that since its the same construction as the right wing which I already posted.



opps! Always inspect your wood, folks! This would of not been good. Good thing I have spare balsa laying around. That seems to be the only piece of wood that came from the kit like that.

That spar was a little bowed was it?

I couldn't help but notice the "TANNING" on the plans... How old do you reckon your kit is?

Rick, my plans say copyright 1986

Both wings done, but not complete. Next step is center wing and then back to the wings.

No hatch, Couldn't figure a way that would look good, It's kind of a pain to remove the pack, but I can charge by removing the prop and cowl,, not ideal,, but easier than removing wing/struts etc.

Also, I made a tray that secures the pack to the bottom of the fuse

Those spars must have come from the same batch as mine,, LOL

good luck

I'm planning on installing a servo tray to the rear of the fuse to bypass the old stick and control arm way and go with conventional control arm hookup.

I found this on another forum and might incorporate the battery hatch idea:

Not much of an update today.. My servo hatches came in. I'm going to need to do a little bit of hacking to make them fit.

I moved the servos to the rear also,, my set up uses a pull pull for rudder,

I added a few pics to my RCG blog page that show my battery install, I don't want to dump pics on your build thread,,, if interested,, https://www.rcgroups.com/forums/show...g#post27938176

I'm surprised Sig doesn't offer floats for this bird. It completely transforms it.

My cowl came in today from Fiberglass Specialties. Really good quality too.

I finally got some time off of work to work on the wing. I sheeted the top and bottom center and glued on the rib caps. I still need to install the leading edge caps and wing tips.
