RE: 2 supercubs flyin?
First off I know you're just getting into the hobby so CONGRATS! You're going to love it and will be addicted just like all of us on here! (BE READY TO SPEND LOTS AND LOTS AND LOTS OF PAYCHECKS!)
If you fly on 2.4 absolutely not... if you fly with FM (72/long metal antenna on your transmitter) then just make sure it's not on the same frequency... frequency number will be on the back of the Transmitter
