Question on the stabs Bryan.
My Pro is on the way and I've been working on the foam wings and stabs that were shipped to me ahead of time.
The stabs are the same size as the original Allure stabs. I thought you had reduced the size and airfoil thickness for the later versions of the Allure and
early Alchemys? Can't be sure from the pictures here which stabs the Pro has. I personally think the larger stabs are a good thing, but would appreciate your thought process.

Hey Dan
The stab should be the new size (smaller ) unless the older ones were sent to you by mistake . But the stab size change on the Alchemy and A- Pro , was mostly done to decrease weight for the composite Manufacturing. You should not feel any difference in the air (maybe more stability ) Some guys liked the feel with the older stabs better but I could never tell an appreciable difference other than a little slower snap with the larger ones.

But I needed some weight room for the production and saved about 3 ounces with the change.
if you want to get a small set let me know I`ll look into it.

I think perhaps it is a mis-understanding on Joe's part as to which stabs to supply. In any event, I'm happy that it occurred, as I should prefer the larger stab based on your comments.
Weight with my foam core wings should not be a problem.
Thanks, Dan

Finally got my Pro in the air: foam/balsa wings/stabs and V4 Contra.
9 flights in 2 flying sessions, and I'm floored at how much I love this plane!
Today I flew it (basically untrimmed) in a 15+mph wind. It held it's lines VERY well!
It flies similarly to my Allure, but I think will be slightly better in a number of areas.

Dan That's awesome!

This plane excels in the wind.
I did a lot of testing before this latest kit improvement. Rudder power and the ability to control track from neutral /static input was my number one goal.
Better stall turns and ease of roll combinations along with a more visible scheme were pert of the improvements.
I`m very pleased with the outcome.

From a building perspective, two things I really liked were:
-Landing gear: straight legs with a robust 1 piece carbon mount. I think these will be much more robust than most other pattern planes.
-Rudder servo push-pull in the tail

I wasn't initially a big fan of the removable chin cowl in an electric plane, but it provides great cooling and access to the motor/drive. Creating and fitting the motor mount was a lot easier. Seems like the nose design helps get more fuse side area up front for the improvements over the Allure Bryan mentions in the previous post.

I wouldn't recommend building your own foam/balsa wings unless you are an experienced builder. It's tricky to get the root profile to line up with the wing fillets molded into the fuse while maintaining all the required alignments.
The composite wings are probably well worth the time and difficulty.

Best flying plane I’ve every flown in F3A. Flew it in strong wind yesterday around 20mph. Unbelievably solid. AWESOME

Thanks!

I have worked hard to continue to refine this model.
I`m So glad someone Else can appreciate the design

It is a work of Art Bryan. I was talking to some friends at the field and they too commented on how smooth it is.
The easiest way for me to describe it was to say that it requires much less input from me to achieve our flying goals and that has to be a plus

it isnít just a step in front of my Element, but a quantum leap.

love it

what tool do you use to make your hinge slots with, in particular, to center them?
