>The stuff about the stab being more sensative to the change in effective >AOA is bunk then? No, if the glider were flying slow enough, and/or if the updraft is strong enough, then the momentary increase in AOA during the accleration period before the glider re-stabilizes will cause the glider to react similar to its stall reaction, normally it will nose down. Eventually, after it's vertical speed adjusts to the updraft, it re-stabilizes, and if trimmed a bit postive, it will re-stablize back to its original air speed and glide angle. The only difference will be the sink rate (or vertical speed). RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
