i have a new P120 on it .. i also have the cockpit kit, and that added enough weight up front to make the plane nose heavy even with the 2 4000mah duralight packs under the rear of the electronics tray, it was still nose heavy .. i ended up adding around 3oz of lead to the elevator for exact balance as per the marked CG dots on the booms ... I taxied it around in front of the house, and at idle it wants to move, the gear is very smooth. I also have a pitot tube speed limiter on it .. I know the p70 bobcats can and have hit over 240mph, so the P120 needs a muzzle on it , because hell no am i ever going to be detining any engine
