37" Piper Cub, upgrade motor, prop etc?
I purchased a Piper Cub from ebay about a month ago and have flown it three times with great success but it needs a bit more power to gain more height.
Currently has the following:
Stock 380 Motor with 7" plastic prop and a 600mah AAA battery pack
I recently purchased a 1050mah 2/3A battery pack which is the max size that will fit into the battery box....CG should be about the same as I had to add 1/2oz to the eng crowl to keep it from wanting to stall at WOT but will recheck this before the next flight.
I want to use the Venom VMG Fireball Micro 370 motor but I am not sure what size prop and pitch to run and if I should keep it direct dirve "as it is now" or go with a 3.1 gear drive which will also require a bigger prop.
Thanks for any suggestions!
P.S. Going to give this plane to my soon as I am saving up for the following...
SuperStar EP ARF w/Ailerons 48.75
Going to use the following JustGoFly 400DF Brushless motor
with the following speedcontroler...

Your links don't work, but I assume it's similar to this: http://cgi.ebay.com/ws/eBayISAPI.dll...965303959&rd=1
What, 24oz or so?
I'd consider the GWS EPS400C-A geared drive, myself: http://www.balsapr.com/catalog/motor...ductId=T704773
Most of the 'hot' can motors are simply re-timed to run correctly. See some of the posts from DeanInMilwaukee on the 400 motor timing...

I took a 480DD plane and moved it to an EPS-400C-A with an 8x6 prop, switched from 8 to 10 sells, and had incredible performance It was an SR x-250 (Balsa). Since sold it to a fellow E-zoner...
