    Start by weighting the nose until the model balances where it should. Toss in some radio gear more or less where it will go. Then weigh in the model with ballast and gear.

    The line pull on a larger model is going to be very intimidating for a new flier. I'd suggest you look into a .15 to .25 size model instead. It's a great compromise between the light almost...

    Your memory hasn't failed you.

    The final balance location was a somewhat flexible thing. Free flighters move the final balance and adjust the stabilizer as part of the power pattern trimming to...

    It's more a streamlined prop nut than a spinner. If it runs true it'll be balanced well enough. If it runs out of true toss it. If it's out of true then you'd need a lathe to true it up again...

    Well, since the air movement will be based on the RPM and the RPM will be based on how hot it gets I think you might want to just live with whatever it manages to move and be happy.

    OK, this was apparently unlocked due to the recent system switchover. It's been re-locked and any new discussions about Soaring USA should be done with a new thread.

    If you try the car setup you'll want to rig it out on a long stick so it's a good 4 or 6 feet out from the car. Otherwise it's solidly in the massive amount of turbulence you'll have due to the...

    If you really want to do such a thing I'd suggest that you scale up the wing by 1.25 compared to the rest. That will give you a little over 1.5 times the wing area of the single wing and a far...
