Default More power without going brushless... Possible?

I'm looking at getting a GWS Me-109. My intro to electrics.
I'll probably fly it stock initially, but I'm sure I'll want better performance down the road from what I've read about the stock set up.
So, without the expense of brushless motors, expensive batteries, along with the needed expensive charger. Is there a way to hop it up?
Or am I going to have to bite the bullet and learn the Greek language of electrics.

There are ways to get more power and not go brushless but they cost about as much. Cobalt motors will help but the brushless systems are better.

I can only suggest replacing the 300C motor with a 6v Speed 300 [?= GWS 350C]. Then save your pennies until you go brushless, on Lipolys, .... [and fly a scratch built balsa aircraft!].

Cheers, Phil

You can get significant power increases by pushing the motor harder with more cells or a larger prop.

The GWS ME109 should come with the EPS350C nowadays. If not, it's a good first upgrade. The EPS350C uses a 6V Speed 300 motor versus the 7.2V Speed 300 motor of the EPS300C. The lower V number means the motor is "hotter," that it will spin faster on a given voltage. Drop it directly in place of the EPS300C with the same ratio and prop size, and it will spin that prop faster, making more power.

Another upgrade you should consider before you even start is going with an 8-cell battery pack. Get either KAN650 cells or CBP650 cells, not the 730mAh GWS pack. You'll have more punch from the shorter, fatter, 650mAh cells even if you don't go with 8 cells, but if you do go with 8 cells, you'll have 25% more available power over 7.

With the 350C and 8 cells, you might want to downsize the prop to a 9x7 Slo Flyer or a 10x6 HD prop. The 10x8 Slo Flyer included with the kit might push the motor too hard and cause premature failre.

Thanks Matt,

That is some good clear info.
