I fly for abt 5mins @ 2300rpm. Charge back abt 2000mah into the 4000mah lipo.

used to fly 500 but I used 6s3000mah. Avg flight duration abt 6mins but headspeed v low cos me not into crazy 3d...cannot afford lah. Anyway would 4s4000mah fit into a 500? how abt the CoG?

Definately able to fit. CG a bit tail heavy so have to add weights to the front. Here is mine :

thanks for the response guys, i have tried my zippy 4s 4000mah in my trex, no problem with CG, can fly in 5:00 mins time, i put a voltage alarm to avoid over usage,,,
