==== Powered and unpowered flight ====
The model has already been fine-tuned for the unpowered phase of flight. When you turn on the motor your model might tend to pitch the nose up when full throttle is applied. You cannot completely trim out this tendency with any motor-powered glider – just be aware of this characteristic when flying your model. In practice, you might have to make slight elevator corrections to maintain a gentle but positive climb. In some cases, there might be a trim change difficult, and the only cure for this is to modify the thrust line of the motor. In order to reduce the nose up-pitching, you have to increase the down thrust of the motor (by using a card or scrap ply packing pieces). The opposite problem is quite rare, but it is possible that a model correctly set up for the glide requires a lot of up elevator to maintain a climb when power is applied. The cure: decrease the down thrust of the motor.

Pred začatím pristávacieho manévru musí model letieť vodorovne s krídlom rovnobežným so zemou. Pristáva sa samozrejme v bezmotorovom lete s plynom stiahnutým úplne dole. Nechajte model zostupovať len pod miernym uhlom; ak klesá príliš prudko, pritiahnite ľahko výškovku. Model spomalí a uhol klesania sa zmenší. Okamžite potom vráťte ovládač výškovky do stredovej polohy a pokračujte v miernom zostupe do výšky asi 5 metrov nad zemou. S výškovkou pracujte jemne, s citom, nezabúdajte na nebezpečenstvo straty rýchlosti, po ktorej hrozí strata ovládatelnosti modelu a pád. Znovu kontrolujte, či je krídlo rovnobežné so zemou a pokračujte v zostupe. Tesne pred dotykom so zemou jemne pritiahnite výškovku, čím trup modelu zrovnáte vodorovne so zemou (tomu sa hovorí podrovnanie) a posaďte model jemne na pristávaciu dráhu. Vyžaduje to opäť trochu cviku, ale vy to určite čoskoro zvládnete.
