2200mah a little too long will not fit between the side link wor..... 1800mah will fit nicely. If you wants better quality IP have 2S 1800 in hard case too. I think it is 40C. KWS few shop have it.
If it is same length as the 3S 2600 battery for EP450 helicopter. Then it is too long and will not fit normally. But you can make it fit by placing it straight on the chassis (not the normal side way) or use some foam to rise the battery above the side link to make it fit. But both ways are not recommanded as I try both before and the handling is not good.....
align servo are quite good. 2xx hkd each. Motor and ESC..... 800 total a little low wor. I am using HW 1s (can work with 2s too) for around 800 and LRP 3.5.
