Settings question

The differential in roll should be close. Cleans the roll up a lot.
au,
Intrigued by the suggested settings above, particularly "20 to 25% more down then up" in the roll settings.
1. Is this "aileron differential" on a conventional wing layout?
2. I usually try to program more up than down to eliminate adverse yaw. Have I missed the point?
3. I'm using a Spektrum tx which requires selecting elevon wing type to get the desired control surface response. Will differential still work with elevon wing type selected?

The nose is wanting to be lifted in the roll, Due to the roll control being at the tail of the aircraft. The effect is that the roll turns into a corkscrew. The larger wings on the C model grab more air creating a larger corkscrew. By increasing the down defection in the roll, this will tuck the nose causing a more a axial roll.

Here's a couple of pictures showing a push rod on the thrust vectoring.

Great build!

Just question sorry..How do you mix the TV servo? Do you mix it with ailerons?

Put it on the rudder or yaw. I have not mixed it with roll.

au117,

Do you fine them to be nose heavy? Did you add any weight to get the proper c/g ?

Hyperflow 30mm question


I've pushed the fan as far onto the motor shaft as it seems to want to go, but the fan blades are just starting to enter the stator ring. Any hints on how far to push to seat the fan appreciated.

My first F-35


Hear is my first F-35 with a new nose after test flight. I have a second one under const. with a few changes. First one nose heavy but flew until to much vectored thrust was used, and rolled it over an in. I made the cutout for moving the battery back.
