touch n go 13

I have just finished building my ifo. on the first flight I immediately noticed that I need more power. It flys but just barely. it will climb at about 1in per minute. Right now i am running an electrifly 280 motor to a 4:1 gearbox with a apc slowflyer 10x4.7 prop. I also have an electrrifly c-10 esc and an electrifly 1200mah 2 cell lipo. Does any one have any CHEAP suggestions such as a motor upgrade, prop ,or gearbox. A 3-cell would be my last resort b/c of my tight budget(14yrs old and make my money by mowing grass, which isnt the most profitable job in the winter) but I am open to any CHEAP suggestions. Thanks alot for your help

You've got the right idea about electric power. A higher-voltage battery would give you more power, but you overlooked one critical factor, the capacity of the motor. No way a 280 will take the excessive RPMs... You'd need a different motor too.

Let's look at other avenues to upgrade performance.

First, a larger prop. Again, you run into motor capacity issues. Bigger prop draws more Amps. Draw too many Amps, and the motor burns up. Same thing with a lower ratio gearbox... A 280 is only good for about 4 Amps before it goes pffft!

You're going to need a higher-capacity motor anyway, so why don't we fix the problem with a different, "hotter" motor? I think a direct swap-out for a 300 would give you the performance you're looking for. One thing you might need to do is run a smaller prop because of the huge difference between a 280 and 300 as far as their behavior at a given voltage.
