Hello,

I would like to know how you center your patriot xl? Do you have the retracts up or down? Are you filling up the tank or you leave it empty? I read that the patriot xl is "jumpy" on take off - any C.G reference I should dial it to or just follow the instruction manual?

Thanks a lot,

tank empty, gear down. CG rangs is going to only be a factor determined by you and your flying style, the MFG suggestion is a pretty good starting place for the first flight.

I agree with KC regarding the fuel tank being empty, but why set the CG with the gear down? I have several planes with retracts and they are always balanced like they fly, with the gear up. What's unique with the patriot?

ALL aircraft including full scale balance with gear extended, if you choose not to do it that way that's fine in your applications, but the correct procedure is with gear down.

I typically balance models in their most tailheavy configuration. Since the gear extend toward the nose on the Patriot XL, I chose initially to balance it with the tank empty and the gear up. On takeoff, it felt very noseheavy and did not want to rotate. Did not work out in this case. Rebalanced with the gear down and it was much better on takeoff. Just another opinion; your mileage may vary.

Hello everybody,

Thank you for all your replies. I like the idea of balancing a model in its tailheavy configuration.

Thanks,
