I thought that using 4s batt. will give me more time and/or more power, so I bought a Tenergy 2200mah batt. When I tried to fly with 4s batt. the tail started moving erratically, and also the blades were making strange noise, so I didn't push it any further, I then flew with the 3s battery and everything worked fine.

Both the motor 430XL and esc BL35X have 14.4 volts in their specs. Kindly let me know what experience others have had using 4S 14.4 volts battery, and what could be the reason that the rotor makes strange noise.

you cant realy just swap a 4cell battery and fly, your head speed mostly likly jumped 1000rpm. ive seen 4600rpm on my scorpion 8 with 4cell battery and 11tooth pinion.

im currently flying a governd 3300 with 4cell on my scorpion 8. and ice 50 esc this is with 12tooth pinion

this is a flight from today. governd at 3300 it pulled 690watts on the climbouts. thats a freaking ton of power

Watch at YouTube

i can governer the 4cell with scorpion 8 and 12 tooth to 3500. 1300tooth will govern alit higher

realy though batts cant just be swapped and fly

Thanks, for your help. I have never used the governor mode and was wondering how can I setup the BL35X for lets say to 3000rpm. From the instructions that come with it, you can only select the Governor mode but doesn't say any thing about the rpm setting.

dont use gov mode with align esc's it will give u a lot of problems... you need to lower your pinion, make sure you dont fly it with 4s packs like that cause it will explode
