DirtyBirdy,

Ahhhhhh, once again we get back to the truth of the matter. (primary) mass balancing the control surfaces. How many times does this have to happen before it sinks in? That fact, and (primary) throttle--airspeed management--; (secondary) sealing the control surfaces, should have ended this string months ago. There has to be a reason that full-scale aircraft manufacturers consider this procedure paramount. Also, check out the balancers on the P-38 Lightning. There were quite a few -38s lost due to this problem.....aggravated by poor power/airspeed managementuntil Tony LaVere (Lockheed test pilot) et. al. went "on the road" to teach pilots how to "manage" the -38... it makes for good reading!

I just cannot help but wonder how much money these misconceptions have cost DavePatrickModels? The moderator should close this one out.......IMHO.
