RE: Dynam E-Razor 450
I would recomend staying away from any advice given by Yadac. He seems to have some type of affiliation with the folowing companies;
nitroplanes,xheli, nitrorcx, and partsworkz
I would not recomend these companies either. Unless you are an experienced pilot you might want to stick with your' local hobby shop. You will always get support from them and can hold whatever you want in your' hands. Most shops will demo anything you are interested in.
