This is a delta-wing aircraft inspired by the late-50s, early-60s American aircraft development. It is stable at high speeds with minimum trim input, and relatively stable at lower landing approach speeds. The speedbrake placement will propagate and promote a nose-up bias, and is very crucial to achieve a solid landing around 100mph...a rare feat for a delta fighter. However, once contact with the runway is made, depress AG1 to deploy the landing chute. This will help keep the aircraft from departuring the runway from instability caused by the smaller undercarraige needed to keep the weight of the aircraft down. Please enjoy your flight and let me know what you guys think! Cheers! -Jim
