Default Tiger 2 CofG Question

I have an old Tiger 2, 60" wingspan that I built a number of years ago in Baja, Mexico and recently brought it back to the states. I had to do some engine work due to inactivity and the engine was slightly "seized". I have taken care of that problem and the engine now runs fine. While switching over from a 72 mghz radio to a newer 2.5 ghz receiver, I have had to switch receiver and the onboard battery.

My question is can somebody tell me how far back from the wing's leading edge the C of G should be?? I have Googled this question and can not find an accurate measurement.

Thank you in Advance. Flysfloats

I balanced mine on the main spar and it flew very well.

Thanks for the reply. I also found a suggestion to use the chord width divided by 3 as the distance back from the leading edge. Will try this tomorrow, watching UFC now.

3 1/2 to 4 and 5/8 from the leading edge at the fuselage sides. You can bring up the Tiger 2 on the Tower Hobbies web site and get all the tech info on the plane. Good Luck, Dave

David: Thank you for the info, exactly what I was hoping to get. I should be able to put the Tiger 2 back into the air later this week as I recover from a fractured fibula, grrrrr. Later, FF

I flew mine many years before selling it with the CG back 38% back from the leading edge with no fuel. With the CG that far aft, I had to bend the main gear back so that it did not sit on its tail. (The gear mounting blocks are a bit too far forward on the Tiger 2 design.)

With a .35AX, the plane was lighter than most so I got away with that CG being quite far aft. Nice thing was that it would really slow up for landing with a beautiful nose high approach. Never had a problem with stalls or snaps unless I was intentionally doing snap rolls. Great flying plane.
