This might be a silly question, but it has got me thinking ??

I am starting to gt all my stuff together for my 1st parkflyer ( and trying to do it right )

My 1st plane is the GWS E-Starter, I'll be using a 3cell E-Tec 1200 for power and a CC pixie20p ESC. Here is my question.

It states in the manual to use 7.2 - 8.4 volt battery I am using well over that will the ESC protect the stock motor (EPS-350C) from being damaged due to the higher voltage, and if so how does it do it ??

Thanks

I read alot, but I need this put in simple terms..I just don't get it !?!

What ESC are you using?

Castle Creations Pixie 20p

No, your ESC won't protect your motor. At 11v, don't expect your motor to last more than 10 flights. I ran a EPS300 at 9.6v, and got an average of 20 flights per motor. That's when I gave in and went brushless.

Really, Hmmm well that is not good news... so would it be wise to start off with a lower voltage pack, say a 2 cell 7.4 volt Lipoly pack

I am looking at brushless in the future but not on my 1st plane, My thinking was off on the battery packs. good thing I own two 7.4 volt packs to start with.

thanks

Use the 7.4v packs. S300's aren't real happy at over about 75 watts. Prop it for around 8 amps.

I have a S-350, I did some digging and found out it can be done, by changing the prop, according to GWS web site there EPS's can take the higher voltage, so I see what happens for now ..

I keep you posted

HAPPY NEW YEAR !!!

Cant the prop be changed to handle it? Im running 11.1 lypol's on my SS with a 1049 GWS prop with no probs.

Anyone know a chart showing prop pulls?

Yep it's the amps that cause the problem. Since amp draw rises with volts, you can see why people have problems going to higher volts.
If you prop for around 5-7 amps, you should get some reasonable life out of the motor.

according to the GWS charts I should be pretty safe you can find them here:

just select what you have, at what voltage and you'll see the amp draw that best suits..

very good info
