I have the 60 size about to go back in the air. It was marketed as a JR Explorer 3-D and now global is selling them. I originally put a YS.53 a in it as that was JR's suggestion. It lacked enough to pull out of a hover but showed the plane flew very well other wise. I have swapped the YS .53 for a OS .61 FX. I hope to get a bit more power and will post the results. Hope to fly this weekend if the weather holds out.

Regards
Bill
