SIG EP42, stock motor, 1100mah NIMH battery 7 cell 8.4 V prop is 7X5, SIG ESC 30AMP controller

I do not want to change to brushless yet, but want to make sure all is working as intended.

I have an RPM meter and want to know at full throttle on a fully charged battery, what should I be expecting here.

And, will the 8 cell battery 11.1V give me more RPM's ?

I know a guy at the field who put a LIPO in the stock setup and he fried the motor ?

The 3- cell Lipo will deliver more voltage to the motor. That will cause more RPM. Just use less stick for the power you need.

We fly a SoarStar on 3-cell Lipo and only use 1/4 stick for great power. Full stick will cause the motor to wear out much faster but man will it haul

Will I blow the motor or ESC using a 3 cell lipo ?

I wold like to try it.

will

Everything will be fine if you manage your throttle well. Just don't get carried away with the new found power

I am not sure my battery charger can handle a 3 cell lipo.

What is the most inexpensive unit that provides adequate charging fo LIPO ???

Mine is a Super Brain 959:
