13 mph winds are medium hereabouts. Faster and symmetrical wings with higher wing loadings do well vs. lighter models with flat-bottomed airfoils.
"T28 Trojan" doesn't tell us much. It could be a 12 oz. foamie cereal-box toy or a 50 pound 100cc gasoline enginedgiant.
If it weighs at least six pounds you're fine.
Thanks, Charlie P. Iguess I will be grounded tomorrow because this T28 D Trojan only weighs about two pounds (31oz) according to horizonhobby.com. Thanks
