Temperature was today 7 Celcius and the tires performed great. The noise level was reduced by 90%. Quite softer landings, very noticeable. The plane started making a noise with the propeller. It looks like the prop adapter was loose. Cant tell just yet, have to try it next time. The Cub is a phenomenal plane, no wonder is so popular! I will reduce my flying time per battery to 8.5 minutes since I have been flying more aggressive. Today I recharge 3600 mA on the 4000 mAh batteries.
