Už viete, že sa vzlieta a pristáva zásadne proti vetru. Počas letu sa snažte model udržiavať skôr v priestore proti smeru vetra - to je preto, aby ho hodný vietor priniesol na pristátie až k vám - a to aj bez použitia motora. S motorovým vetroňom s elektrickým pohonom sa bežne (ale nesprávne) lieta tak, že sa vylieta takmer všetka energia uložená v akumulátoroch, a na pristátie sa ide kĺzavým letom až vo chvíli, kedy ochranný obvod v regulátore otáčok odpojí pohonný motor (napájanie serv a prijímača zostáva zachované) alebo výkon motora už nepostačuje pre stúpanie. Tento spôsob, kedy si neponecháte žiadnu rezervu napr. pre opakovanie pristátie, je veľmi nešetrný k pohonnému akumulátoru,
			skracuje výrazne jeho životnosť. Zvyknite si pristávať hneď potom, čo spozorujete, že výkon motora klesá („vädne“) v dôsledku poklesu napätia akumulátora.

===== Powered and unpowered flight =====
The model has been already fine tuned for the unpowered phase of flight. When you turn on the motor your model might tend to pitch 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 practise you might have to make slight elevator corrections to maintain a gentle, but positive climb. In some cases there might be a strong trim change, 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 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.
