I also have the yellow canopy. It was hard for me to see the helicopter when the sun was going down with the stock one and now it is easier with the yellow. Only you can decide when to take the training gear off. Only do it when you are comfortable flying and the chance of you crashing are really low. It seemed like I didn't have enough power to lift off with the gear on so I took it off before I was ready. I was almost at full throttle before it took off then it shot up really quick. I still crashed after that, but I didn't really have an option. I haven't really looked at batteries for the Pro. I like USHobbysupply, helihobby, and helidirect. That should be a good place to look to find that battery you are talking about. When you are looking at batteries make sure it has the same balance connector on them. I really like my sim too, but the helicopters it has don't fly like any of mine. Keep having fun flying and hope it isn't to windy tomarrow. Today I was really regreting staying up till 2. I just hate not finishing something and that means staying up late to finish it.
