Does anyone know what the flap speed is for the out of reflex '0' degree position? The RV10 has a higher speed for '0' degree than the the top of the white arch speeds for the rest of the flap positions. Thanks Barry
I believe Van's has recently clarified that there is no longer a speed restriction for the 0* flap position on the RV10. Would assume the same applies to the 14. It always seemed odd to have a speed restriction with a neutral flap.

I believe this is correct. However, the original limit didn’t seem odd to me. Full up, the load is carried by the hinges and the aft spar. In trail, the smallish actuating arm carries some of the load. So, at a minimum, it would have required some engineering to determine if the strength was there.
not an aerospace engineer, but I would expect no load on a flap or elevator that is "in trail" or 0* Maybe I have more to learn in this area. On my 6, the ailerons naturally find an in trail or 0* position. I would expect more load on the actuating arm at -3 than 0
Think about the ailerons. In neutral, the stick is dead, no load or resistance. If I move the ailerons to -5/+5, I feel resistance on the stick. They want to go back to in trail, which to me means less load on the control rods attached to them when neutral.

The ailerons have a perceived zero load at zero deflection because they are linked together left and right. If you disconnected them, they would both float upward to some angle, maybe -5 degrees or so?. The RV-10 and 14 flap has less lift load on it at -3 than it does at zero deflection. But the loads at zero are small enough that if Van removed the distinction, it means the linkage is strong enough to hold the flap at zero up to Vne, which I think is extremely likely.

How much reflex (how negative can you go) on aileron adjustment before the frise aspect starts causing drag?
