How powerfull are the stock motors on the twinstar? Because i live at 7,000 feet and was wondering if it will fly well at this alttitude?

The power capacity of the motors does not change with altitude.

However, the power OUTPUT will, due to the thinner air.

The solution for electrics is to simply switch to a larger prop. It may require a little experimentation to get the right combination, though.

the stock motors are not very powerfull, work ok but
I fly mine with a pair of towerpro 2409-12 brushless motors, 25 amp towerpro ESC and 7X6 props 3s 2200 and 3300 battery awsome, takes off from grass, unlimited vertical if needed, fly mostly at half throttle wonderfull flyer, you will love it
got it for winter time but has become a regular fun flyer

Those TP motors are so cheap nowadays you might as well change. It flies fine on the stock motors on either 2S or 3S at 150' ASL. 7,000' is pretty high ... I would just go brushless.

we have more than a dozen of those cheap motors ( 2409 and 5055-580 ) in our club, flown and abused in gws warbirds and combat coro pushers for 3 years now , only 2 motors burned out their bearings, lots of bent and broken shafts but not one of the motors has gone south ,same for the 25 A ESC, even used at 30-40 amps ( burst )
I have seen some motors so hot you could not touch them, yet they are still going strong.
maybe we are lucky
my known facts, I personnaly own 5 of them ( 2409 ) and 2 /5055-580 and over 400 flights total
cheap yes but try abusing the expensive motors and see what happens. lot' s of money down the drain
