A 50mm Medusa is more than adequate in a crt.5!!! The 3300kv is a good choice for 3s. I have a 36-50-4800 that I run on 2s in my crt.5. A bigger motor is def not needed! Mine has never been over 130*, plenty of power, wheelies occasionally, and good runtimes. Medusas' are awesome motors and the 50mm series is a great choice for the crt.5. Your voltage determines kv.

As for the batteries the reason why MA is looked down upon is that they are not rated properly. They are 15C discharge at best, they tend to go out of balance alot, and are over priced for what you get! Many on here have had good luck with zippies but Enerland based cells, (such as polyquest, flightpower, thunderpower, neuenergy, and enerland) are considered the best. I started out running 2s 6000mah MaxAmps in my crt.5 then switched to a 2s 5000mah Neuenergy and the difference was day and night!
