RE: questions
Uh,
If you look closely at the positive feedback at e-bay, they look suspicious to me. Many are the same and many repeat addresses. I think you should STAY AWAY...put your 20.00 toward a decent trainer. Buy once, not twice. It looks like JUNK to me and the responses to negative feedback were laughable.
Get good RC stuff...you will be much happier. This junk will make you leave before it gets fun.
These types of vendors are to be avoided, but hey...it's your money.
Good Luck
