Earl, you are a very busy man. I'm glad that you like several on going builds all at the same time. I start a lot of builds but take a long time to finish. I'm more for small models, but I do have a third hand partial P51 Nosen kit that has the wing built and covered on the top only. It's on my bucket list. Also have a 1/3 (RC Guys) Pitts waiting for assembly.
I just finished a Joe Wagner Dakota and am presently puttering with small rubber stuff.
Any thoughts on a second dog? I'm going on 69 and have three dogs, the youngest is 4.
They are all soft-coated Wheaten Terriers and are hypoallergenic and don't shed their hair. They all make great company, but are no good at building. I'd like to get a Bouvier des Flandres
( large herding dog breed), but they might shed a lot of hair?
John

My Bassett is the world's best building companion.

You may enjoy the breed. They're great in a shop environement.

We're going to need windshields, and the Citabria has a compound shape, that is usually replaced with a flat one, which is fine....

I'm hoping to pull one once in a while, when the form is finished. This will have all the scale curves in it, and I'll just 'stretch-pull' the plastic over the form...I'm back, messing with this now...

Citabria down & right thrust

Good morning Earl, thanks for the down and right thrust response, for my application, I will use a Quadra 35 with CDI Ign.; dimension length with mount and allowing another 3/32 in. cowl clearance and an 18 in. prop with 1/2 in tip offset equates to 3 degrees firewall angle and the mount offset by 5/16 in. which will allow the prop adapter and cowl center alignment.

This should remedy the climbing tendencies under full power however when de- accelerating the ballooning effect will re-appear, don't you think?

I have given a lot of thought on building a semi symmetrical wing using the NACA 2412 since the Decathlon models either use the 1412 or the 4412 airfoil, however a quick study of the plan profile shows some difficulty incorporating this airfoil given the illustrated structure of the fuselage.

Would appreciate your comments.
Bill

Nosiree- I don't agree at all...The offset thrust is there to counteract the propwash, or 'thrust' while under load....at idle there is no load, so offset thrust isn't in play....just the natural trim of the model.

Thrust

Earl, I can see your point and I was thinking of the reaction as one begins to reduce the throttle.

What are your thoughts on employing the NACA 2412 airfoil and modifying the wing saddle

I'm building one with symmetrical wings, so I'm good with your building the semi-symmetrical ones . Wouldn't hurt to shorten (clip) the wings by one rib bay, either.
I didn't modify the wing saddle though.....I'm just letting the wing root butt up against the cabin.
