Hi all, I have only just started trying my hand at this form of flying, started with a modeltech 3Demon which has allowed me to do some basics ,hovering , spins not quite flat but close for this plane etc.
I have just brought a 26cc sukhoi 26m & have heard that putting the fuel tank behind the CG point allows it to be more tail heavy but makes landing easier after the tank has been run down.
Do many people do this with their 3D birds ? are there any real advantages in doing this ?
I guess what i'm asking is is it worth doing.
cheers Steffan.
I haven't tried that but I may sometime. Ihave an Aeroworks 1.20 size YAK 54, the tank is ahead of the C.G behind the firewall, I don't like it. If I use an aft CG for 3D stuff, it only really goes tail heavy the last half of the flight. with the starting out C.G. in the manual I can't even tell the difference betwen the beginning and the end of the flight.
My 50cc Airwild has the tank mounted right on the C.G. it is set up tail heavy, and can be difficult to land in a head wind. I guess the low wing loading and the Center of Gravity makes the nose point up, When I land it in a descent head wind I have to hold down elevator to land it. very un-natural to me. Still better than trying to land it even with minimal tail wind.
