Hi all! Im newbie here and in helicopters as well so looking for help to pick correct remote for my Unknown Heli... I got this in market for couple pounds without remote control with slight damage but nothing major. Model is unknown for me, but looks like double horse 9053, 9101 or something like that. After online research looks like 9053 and 9101 use same controllers, but there is choice between 27 and 40mHz, is there way to identify which one I do need?(sure if im correct with identification of heli...) Any help appreciated, Thank you!
