Hi! I have tower voyager and it is very nose heavy, I have battery as far back as I can without having to cut the plane open. The battery is behind the servos and it's nose heavy, I have added wieght to the outside of the fuse( but that looks kinda funny. what would be the best thing to do?

Seems strange that this plane would be that nose heavy. Are you using one of the recommended engines for it? And have you made sure you have the correct C of G range? Can the engine be mounted closer on the mount rails back towards the firewall?

If everything else is correct and it is still very nose heavy, do what you can to get some weight from the front end before adding dead weight ....... I know you hate to cut into the plane but what I have done in the past to to cut a small square out of the bottom as far back as you can and insert some weights glueing them on the inside and seal the hole back up. I really hate to have to add much extra dead weight to any plane as they should be kept as light as possible at all times but you have to do what it takes to reasonably correct this problem.

As Gary, mentioned, that seems very unusual...

have you tried using a lighter prop (wood)?

Are you using a spinner? Can you work around not having one?

Is your wing located where it is supposed to be? If it is attatched by rubber bands they have a tendency to move around...if it slides too far back, it could show the plane as being nose heavy.

Can you put a lighter foam nose wheel on?

And lastly, are you balancing it with the fuel tank empty? This is very imprortant as you could end up with a very tail heavy plane at the end of the flight when the fuel is gone.....

How nose heavy is it. What I mean is where is the C of G to the referance point. I just finished a Patriot 40 and it is 1/2" forward. That does not concern me until I test fly and then add from there. If it is to the rear then do not fly it as it will be very unstable. You will require a touch of more up elevator when landing.
I have also added an extension to the battery pack and wrapped it in foam and moved it as far aft in the fuselage as I could get. As long as it does not interfere with the controls and wedged so it does not move inverted that will work. Rossi 40's where a good example when balancing. Potent but heavy.
Let us know how you make out.
John

try

My Uncles plane is just opposite it has 2 much up force on front,.He was advised to put a bit of a shim in under his motor mount to tip the engine down a bit.If u do this in reverse with a small piece of wood,to tip ur engine up a bit u should get a bit more upward pull thus taking away the nose heavy feeling u are having.;
