Hi Igorcar. The recommended CG it very easy to achieve without any extra weight in the nose. The Turbine all but sits on the CG so it dose not matter how heavy or light it is. As you can see from the first in the set of pics the Rx and ECU lipo were under the canopy and a UP2 and UP6 just in front. I fitted the ECU just in front and along side the turbine on a shelf extended from the turbine mount. I also fitted a 200mm UAT in the same position to the left with the pump and valves underneath the duct. this kept all the fuel lines and cables very short and left the front bay under the canopy free to fit the RX to the rear again keeping the servo leads as short as posabel and battery's easily accessible. I did find room for four more air tanks so had six in total, not really needed but they weight next to nothing and you cant have too much air:-). It was a very quick build and was flying the second weekend after it arrived. The only hassle I had with it was getting the sequencing for the main UC and doors right. Wheels lift OK but are "steady" certainly not fast especially when in flight. A sure way to be sure the doors don't beat the wheels would be to use a trip valve fitted to the mains so the doors don't close until the wheels are tucked away. One good thing about the way the main UC are set up is even if the air pressure is low they all but drop out on there own and need very little pressure to lock. Looking forward to hearing and seeing your build as you go along and all the best for when you finally get it flying. Regards Mark V
