Prophex,
Wait a minute, is the esc not the same as the speed control ? Isn't the phoenix 10 amp both a speed controller AND an ESC or are these two totally different things ?
Typo on my part. Should read "The two speed controllers controller leads will be hooked up to a Y harness and then plugged into the RX". ESC is an acronym for Electronic Speed Controller.
You say more juice, but how much ? wouls a 3-cell 730 mah be enough to power two 2208/34 axi motors or do you need more then that ?
You can run the 2208/34 on a 2 cell or 3 cell. The difference is the size prop you can run to not overamp the motor. The 2208 has a max efficiency of 4-7a. With a max loading of 8 amps. As you go above the Max efficiency rating you begin to generate heat. Heat kills brushless motors. More cells (voltage) above a 3 cell isnt recommended on the 2208 series as it is too much voltage for this little motor to handle. The 2208 is a 2 cell lithium or 3 cell lithium motor. You will have more thrust at a higher RPM with the 3 cell at a weight penalty of a 14 grams. That doesnt sound like a lot, but on a shocky, every ounce counts.
If you are going to fly indoors, go with a 2 cell...if you plan on flying outdoors, I would go with a 3 cell. The power level between the 3 cell and 2 cell will be noticable. However, be mindful of the amps. You might have to drop to an 8X3.8 to keep the amps within the max efficiency levels. You will feel the weight difference of the extra cell the 3S 730 carries, but the extra power will make up for it.
Also can you not just use a 25 amp ESC instead of a 10 amp one ? (so that the rule is: as long as the amps of your ESC are bigger then the ones the motor needs, you're safe)
You certainly can run a P-25 in place of the P-10. However, as I mentioned before, there is a weight penalty. Having said that.....I run a P-10 on one Shocky and a 20 amp on the other since it is what I had. Two identical setups with regards to motor, battery and servos and I can not feel the extra weight of the 20a controller.
