Model Tech Magic.... I'm set up with brushless and find that RTF it's tail heavy. The CG is 3/4 inch back from the recommended.
Anyone have a Magic that can advise the results of leaving this permanent.
How will normal landings and general flight perform?

I'd put enough lead in it to bring the CG up to where it's recomended, then start removing it a bit at a time till your happy with it. Flying with it that far back all at once could have dire consequences.

Thanks for the good advise. Can I ask if it's just good general advise or did you own a Magic ??
Some planes recommended CG is not accurate. I'd really like to hear from people that know this particular plane.

My Magic was never tail heavey, but I've played with the c/g a lot. It seems quite tolerant of a rearward c/g IF YOU'RE A VERY GOOD PILOT! Use a Higley heavey hub or platt spinner weight to get it forward and follw the above advice.
I opened the firewall just below the motor ans slip my battery in. It also allows me to move the c/g around.
I've had my Magic since they first came out and it's still my comfort plane if I haven't flown for a while or have jsut re-kitted something I've worked on all winter (-:

I did own a Magic quite a while ago. Real good funplane but I didn't like the inverted performance with the flat bottomed wing, but it is very agile. I usually go with what's recomended, then move it to suit myself, just so I don't get any surprises.

Thanks for your input Walt.
I was hoping that I could get away without having to add ANY weight. I'm only pushing just under 400w on a Eflite 25 Outrunner.
Rather than use a weight up front, I was going to move the motor forward an inch or two on four 1/2 inch dowel rods. this should add just a little weight and move the 7oz. motor foward a bit. Moving the CG 3/4 inch shouldn't take too much ?? I only had 2oz. of weight and that was not enough to bring the CG where it needed to be. I'm thinking 3 or 4oz.
About the battery installation... I'm running 3S2P 2100 lipo so there is no room to move stuff around. I knew it was going to be tail heavy so I mounted the servos as far forward and used a light pull pull setup for control in the tail.
