Great information! Can you please explain why a nose heavy plane will climb, and why a tail heavy plane will dive?
P.S. I found this information:
"If your bird, instead, steepens the dive, you are tail-heavy. This is for the same reason as why it climbs when nose-heavy: you're flying faster than your trim-speed, so your elevons exert more up-force, causing your nose to pitch downward. The elevons were literally "propping up" the tail of the aircraft at cruising speed." Source:
