I am about ready to maiden my f9f and have read all the comments on this site. I have landing gear and an admiral 1600 mah battery. I am using a Spektrum AS3X 6ch reciever. By moving the ESC forward my CG is right at 45mm as per the manual. Based on the comments should the CG be moved forward? What CG have most of you had success with when flying. I did not add any weight but have no desire to maiden a tail heavy plane. Should I leave the CG at 45mm?

Visited Deland, Florida today, about an hour from me. Shot this video of someone launching a 64mm Panther with a catapult ???? https://youtu.be/TXZn6DUiI6w

Double check the other indicators of if CG is correct before changing based on just this one indicator. This is one of the way down the list indicators of possible CG being off, that can be caused by other things.
Its safer to have the nose drop than to have it swing up.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

I thought I had the CG a little forward of the spec, I was wrong. Crashed it first flight. So I've repaired the plane and I'm going back to old school and balancing the plane at the front of the wing at the tip. (not the tank but on the wing itself.) I've added 20 grams of weight to achieve this balance point. I do have the landing gear installed. Should be flying it in 2 days and will post the results, good or bad.

I'm not the best flier around and The F9F is my second EDF, my first was and still is flying, F18. The Panther took off fine but it quickly went nuts and was uncontrollable. Inspected the plane for things that could have gone wrong but found nothing out of the ordinary. I'm pretty sure it was a CG problem but won't know till I fly it again. I've flown gas powered planes for years but just got into the foam planes because their already built. Don't get me wrong I love to build planes but I don't have the time anymore.

I think your right, a little nose heavy probably a good thing on this little EDF. I checked it again and still didn't feel comfortable with the CG so I added another 5 grams of weight for a total of 25 grams to the nose and she's a tad nose heavy at the wing tips, which is where I feel comfortable enough to try it again.

Well it was more than 2 day's but I took the F9 out today and with the 25 grams of weight in the nose she flew just fine. Maybe a little nose heavy, but I'm going to leave it where it is until I get it trimmed out good. Had to cut the flight short due to a receiver issue. For the record I'm using the standard 11.1 volt 1600mah battery with the landing gear installed. Battery as far forward as it can go without interfering with the nose wheel servo. I added 20 grams to the nose cone and 5 grams at the front of the canopy cover. The plane was a little nose heavy but balanced at the front of the wing tips. NOT THE WING TANKS. That's old school knowledge from the man who taught me to fly 25 years ago. Mr. Bill Lazano.

Hi guys. I've just bought a f9f panther. I've only flown the e flight apprentice but decided I wanted to move onto edf jets. I'm doing as much research as possible to get her set up right. I'm not rushing into flying her. I've a futaba R2008Sb receiver and a futaba T8j controller. What else do I need guys.

Irish_steve, If you haven't flown EDF jets before, you might consider a different plane to start with. You see a lot of people saying the CG is not right in the manual. My experience with the F9F was not very rewarding as it only lasted for 3 flights. The plane is quick and if the throws aren't set low enough you will experience some not so pleasant moments trying to fly the thing. It was my second EDF and the first one retired sorta. I would recommend the F22 4S plane as this plane is so easy to fly it's not funny. I've rebuilt the Panther and installed a 12 blade 4S setup in it but haven't tried to fly it. I suggest you read through the thread and make your decision based on the experiences of a lot of people who have and have not had success with the Panther. Good luck.
