Hay brownd,
I doubt you will have any flying issues with such a small out of centered stab...even if it is a couple degrees out of true-side ways. The Ultra Stick (and all Ugly Stick types) fly well...and you will be very surprised when you go fly this model.

I've an Ultra Stick .40 that I'm now rebuilding after five years and over 400 flights. I needed to install a new fire wall (broke in three different engines on the model...K&B .45 Sportster, K&B .61 Twister and Super Tiger G.90), re-inforce the second bulkhead where the wing pins plug into the fuse, and a re-cover of the fuse. The model is well built, flys very well and I can fly it in high winds. I'm hard on my models, and I abused this model, rode it hard and managed to ware out two sets of tires on the kit. I did install a Kleet Tail Wheel when I first assembled the model, and its still in flyable condition...: )

I placed my servo's aft near the tail, re-inforced the wing pins (installed brass tubes over the wood dowl pins), reinforced the main landing gear floor (inside the model) and flew it first with a four servo wing...and went to a two servo wing later, using flaperons (the programing got to involved for me with my Tx).

I also have had a few less then good landings with this model and the repairs are easy. By the way, I placed my elevator and rudder servo's in the tail for easy access for adjustments and to add a bit of weight in the tail section. Even though the K&B .61 Twister is a light weight engine...placing the servo's aft helped the CG.

It is a great flying model, very forgiving and a good second plane for the newbe.

Soft Landings Always,
Bobby of Maui
