RE: CopterX CX 450PRO V3 Belt Version 2.4GHz RTF
To clarify the SE V2 is a copy of the TrexSEv2. The CopterxproV3 is is a copy of the Trex pro series with torque tube or without... your choice. Parts will not be a problem...I have them in the store. I would choose the V3 because the frame set and head is a bit stronger designed and the servo mounts insure no interaction....As far as electronics here is a list I would choose from ( and have).. Trex450m motor, or older version of the 3770kv.or Scorpion 2221-8.. Esc I would use an Align 35x. with a 6v regulator.. (the blue heat sink). Hitec hs 65 servos, or Align 410 digitals. Spectrum radio system with a 6200 receiver. DX7 would be nice but the DX6I with 6200 combo would be perfect. A Futaba401 gyro, Futaba520 gyro (my choice) and a 9257 tail servo or 9650 servo or JR290 servo. If you use the 9257 you will need a step down regulator to 5.1v as it will only run on 5V. (about 6 bucks) The others will work fine on 6V. I would invest in a really good charger or chargers such as the FMA cellpro4,8 or 10. or the Hyperion brands in the 606 or 720.. Charge 2 at a time..... Most folks around here are using Zippy flight PRO 2200 MAH 3 CELL BATTERIES with great success. About a third of the price. from Hobby City.
I hope this helps,
Jim
