Sorry for the delayed response, guys - thanks for all the advice!<div></div><div>Well I'm back from my trip and decided to go over the model to look for any of the listed issues.</div><div></div><div>dbacque - I had covered it almost immediately after landing with an iron plugged into my power box and some spare covering. It had not obviously not been as waterproof as I had hoped because when I pulled the patch at least half of the elevator was full of water, including the middle section where the control horn attaches. The weight of the water was enough so that with the model turned off, the elevator would drop all the way down, moving the servo in the process.</div><div></div><div>I checked the elevator servo for issues and found none. I left the model and TX left on for about two hours, played with forcing the controls, etc, but everything checked out fine. There didn't seem to be much flex from the pushrods either. Floats were water free and I couldn't find any wet wood from what I stripped off the bottom and sides. I had gotten them from a yard sale, covered in rather tattered EconoKote, so I figured new film was an acceptable fix. I'll glass them to reduce any chance of them getting wet in the future.</div><div></div><div>In my mind, the weight of the water at the extreme end of the model will have easily changed the C of G, which will have at least made the trim more sensitive. If the wind dies down tonight I'll take her up and see what happens.</div><div></div><div>Thanks!</div><div></div><div>Graeme

[edit] Flew the model three times, no issue. In fact, I it seemed to be climbing a bit at half throttle like a flat bottomed model should. No water in the elevator this time - it was easy to check because I covered the bottom with transparent film this time!</div><div></div>
