Opjose -
Can you tell me how much throw you're setting for the spoilerons? Give me measurements at the root - closest to the fuse so I can make sure I'm measuring from the same position as you are.
Hitting the flap switch on my real plane raises the "spoilerons" exactly 1/4"
In the G3 model the spoilerons are raised a bit higher than what I have on my plane.
On my real plane I also have the ailerons raised 1/8" from level with the wing, as measured closest to the fuselage.
I did this after playing with the spoileron settings while the plane was in the air. My intent was to get it to fly level, hands off. That 1/8" helped a great deal with this.
So in effect my real spoileron setting is 3/8" up for both ailerons.

I'd like to know how you're mixing your elevator with it.
On my real plane using my JR radio, when I engage the spoilerons I add down elevator of approximately 1/8-1/4"

Using the model in G3, it wants to pitch down when I raise them, so I"m assuming you're mixing in up elevator?
No. The spoilerons ALONE are producing the pitch up effect. Don't thing of the Bobcat like a standard plane. Think of it more like a delta wing.
Up ailerons ( really flaps in this case not spoilerons ) causes the nose to pitch UP, the opposite of what would happen in a normal plane.
I actually have to add a bit of DOWN elevator both in G3 and my real plane to prevent it from going really nose high when the spoilerons are engaged.

Also - what is your throw for the elevator?
On my real plane it measures at 1" Up and 1" down.
I have my aileron throws at 100% travel which gives me about the same deflection as in the G3 model.
The real plane rolls VERY fast at any speed.
I use about 50% Expo on the high rates and 35% Expo on the low rates with the rates set to 100 & 60% respective servo travel.

I like the sensitivity of the model, but ailerons are a bit twitchy for my taste....however, I snap-rolled the plane, and WOW!
I gotta try that with my real one, but I'm afraid to rip off the tail booms!
Yup that's what mine does. Though I never snap roll it at WOT.
I epoxied the booms and stab in place and I installed metal screws and washers, etc. all around.

The one thing the model I sent you doesn't do like the real deal, is the "wallowing" the plane does as it approaches stall.
I was still playing with the settings to get the same observed characteristics so I don't consider that a "final" version... just something that would let you see beforehand how the real plane will handle.
