RE: HobbyZone Super Cub LP...I hate it.
I recently got a used super cub and a spektrum dx5e for $130.00. I have only flown it once for about 5 min and I already love it. The wind has been too strong lately so I have been working on some upgrades. I have added ailerons, flaps and landing lights that are controlled by the 5th channel on my radio. This is my 4th plane and by far the best. It flys great and I am able to cruise at 20% throttle. I expect to get about 25 mins on a single charge.

When you do repair work, it's a good idea to make sure the balance point has not moved beyond suggested limit's...before flying!
Sometimes, in order to put the plane back together sturdy enough for flight, the combined weight of glue(s) and various pieces of strengthening materials (if used) can produce a new balance point which is NOT within the recommended range.
Ok...now I will get to your question.(sorry about the lecture...it's been a long day, and I am still thawing out)
From the instructions, determine where the balance point for your particular model should be.
Then, with wing mounted and plane prepared for flight (tank empty for glow engines), place a fingertip on each wing-half bottom and just against fuselage. Lift plane carefully. Slide fingertips along width of wing, forward or backward, until the plane stops teetering and in a slightly nose-down attitude.
This is where the balance point, at this time, actually is!
If it falls within the recommended CG range, you're good to go.
If not, either relocate radio components(if possible) or add weight to nose or tail accordingly, to bring the balance point within the recommended range.
Attached is a drawing of a general way to determine a balance point.
If you do have to add weight, make sure to attach it well. You don't want it falling off during flight.
