Great Planes Super Sportster EP

Has anyone else flown the Super Sportster EP. I flew mine for the first
time last weekend and let me say, WOW! This is one great flying bird. I
only have one concern. The ESC that came with the plane momentarily
applies brakes to the prop when the throttle is pulled all the way
back. This doesn't affect the handling of the plane but I'm afraid I'll
strip the plastic gear in the gear box. Anyone know of a possible
solution to this??

Thanks and have fun flying !!!

My guess is that it is the same controller that is used in the Great
Planes Spectra ARF which has a folding prop. The brake is used to stop
the prop so that it can fold along the fuseage sides thus reducing
drag. You are right, the braking action puts a lot of load on the
gearbox.

The Super Sportster EP is a heck of deal at $120. Comes with Motor,
controller, and 2100 mah battery.

I'm still waiting on mine. Should be here any day. Can't wait to build it and get it airborne.

Does anyone know if the ESC is 3 cell 11.1v LiPo capable?

What do you mean? Can handle 11.1 volts?

Just wanted to know if the ESC that came with the Super Sportster EP can handle 3 cell LiPo.

Re: Great Planes Super Sportster EP

By handle do you mean is the cut off voltage set so that it will not ruin a
3 cell LiPo? Are you asking about connectors?
Most ESCs will let you plug in a LiPo but the will let it run down below a
voltage level that won't ruin them. I do not know if you ESC you are asking
about is settable or set for a 3 cell LiPo.

You could use it but you will have to keep track of the voltage yourself.
It is not going to cut out at the proper voltage level for a 3 cell LiPo.

Here is a link to the info page. Note that this esc has been discontinued
in favor of a 35 amp LiPo compatible esc.

Replacement esc that is LiPo compatible.

Of course, by `LiPo compatible' you mean that either 1) the cutoff
voltage is configurable, or 2) it's default is appropriate for
whatever number of LiPo cells you're using.

Most ESCs that aren't adjustable cut off around 5-6 volts. For a two
cell LiPo pack, they'll usually work as is. Yes, 5 volts works out to
2.5 volts per cell, which is too low, but if the battery is under load
the voltage will drop a bit anyways.

In any event, you don't really _need_ an ESC that knows when to cut
off. Instead, it should be quite obvious to you when the batteries
are running out of juice -- the power will go way down first.

As long as you're paying attention and actually land the plane when
you notice that the power is going down, you'll not have any problems.
The only possible exception that I see is a motorized glider where you
may fly it far out and a loss of power may not be very noticable.

I guess you mean a 2 cell lipo. If s, it's a waste of $$ unless you
have one around. The stock motor is anemic. I tried better brushed
motors, finally went brushless and lipo. It's a great flying model with
enuff power.
