It's no picnic if you are as picky as me. Heat helps but the glue is in the color and much of the color will stay behind. It can be cleaned with Trim Solvent or the like but is a mess. It's not a big problem unless you are going to put a light color where a dark color used to be. If you are using the same colors just get it smooth as possible and leave the rest.
The other thing I would ask, are going to cut the hinges off and recover the surfaces or are you going to cover on the plane? If you are going to leave them on than I would leave some of the covering. Leave all the areas of bevel and the inside of the surfaces like the area between the start of the AILE close to the wing. Then when you recover just overlap as close to the centerline as you can so it wont show.

Sorry but Monokote color is in the adhesive but Ultracote adhesive is a clear layer separate from the color. A bit of heat from a heat gun will allow you to remove Ultracote with ease. Some of the adhesive will remain on the wood but it can be easily removed with acetone, MEK or trim solvent and a rag or paper towel. Sand and recover. Done this many times!!

Ditto to all of the above.

If you've tried heating and peeling the covering, but it's leaving the adhesive/color behind, take clear packing tape, lay it over the adhesive/color, rub it in with a finger, and then peel it off. It will take the adhesive/color with it. If the adhesive/color doesn't come up the first time, repeat, but run a warm covering iron over the tape before peeling it off to get the adhesive to let go. Might make the balsa fuzz a bit, but a light sanding solves that. As always, try it on an inconspicuous spot first to get the process right.

TCampbell's suggestion works. I have tried it myself with 99% successful removal. And, yes, using the same colors over the old colors helps hide the show-through of what did not come off.
