Default Need help with EP J3 Electricub

I have Great Planes J3 Electricub with the standard motor/gearbox set up. I was looking to put something else in it to give it just a bit more power. Any suggestions on what to put in this plane?

SPECIFICATIONS
Stock Number: GPMA1153
Wingspan: 41 in (1040 mm)
Total Wing Area: 269 in² (17.4 dm²)
Wing Loading: 7.5 oz/ft² (23 g/dm²)
Weight: 14 oz (395 g)
Length: 29.5 in (750 mm)
Includes: 280 motor, 3.5:1 gearbox, ESC, 8-cell 9.6V 600mAh NiMH battery and 10x7 prop
Requires: 3-4 channel radio w/2 micro or NanoTM servos and charger

Here's a link to it on the Electrifly site: http://www.electrifly.com/discontinued/gpma1153.html

Couple of things to consider. To increase the performance you would want to go to a brushless set-up using lipo batteries. That would mean removing the gearbox set-up and making or buying a mount to install a brushless motor. Then add an ESC and a lipo battery . then you would need a charger capable of charging a lipo battery.
So the first question would be;do you have any electrics running lipo packs and a charger capable of charging them ?
If so then you would be looking at spending around $60-70.00 on the low side to equip the plane with a new motor, ESC, LiPo battery and accessories. If you needed to buy a charger then add another $30.00 + for a basic "4-button" multi-charger.
I would say something like a 2805 brushless 1300kva (Blue Wonder type)motor, 18 amp ESC, a 11.1v 1300mah LiPo , and a 9X4.75 prop.

If you look down thee is a thread about an elictricub. This is the power system I have and the one I recommended. Runs an APC 12X6 prop and have a lot more power and flight times. If you read the other thread, I laughed about the cleared work bench comments.

They are out of stock right now. They come and go fast.

Blvdbuzzard, thanks for the pointer but this is the smaller Electricub - only 41 inch wingspan.

I saw the electri cub and ran with it.

For something that small. You could go with something like this.
