I have to agree with Kram, I'm still flying a TF P47 pregold edition with a K&B 61 flaps and rhom air retracts, covered in monicote. I did not have to add any weight for balance. It's a great flyer, landing with or without flaps is a breeze. I've started to build a gold edition in the bubble verson and plan to keep it light. Just my two cents worth. Peter.

Believe it or not I only added a Higley heavy hub to balance the plane! Moving as much as you can forward is the trick (battery, servos, air tank, etc). I'm not a big believer in weighing down such a small plane. I've seen so many guys show up with a TF 60 size bird that's been glassed and painted with all the bells and whistles. If the plane survives it's first flight they complain that it's a bear to fly. OF COURSE IT IS, at the 12 lbs and up that some of them weigh! To each his own but I personally would rather fly and enjoy the plane than sweat bullets every time it's in the air. These planes, if built as intended, can look the part without overbuilding and overweight and the resulting bad flight characteristics. I'll post a recent picture of mine and you be the judge.
