CG INFORMATON: In reference to the SIG CAP EX 231 73 inch. Ihave just completed mine with a DLE 20 GAS engine with aRECEVER3000 MAHLIFEBattery and a Electronic Ignition POWEREDGE 1900MAHBATTERY.Both batterys on top of one another had to be located just in front of the landing gear, and the Electronic Ignition just infront of the batteries inthe out flowair opening in the bottom of the NoseCowl. Along with this Ihad to place 8 ounces of lead that I melted to form a flat conforming profile to the inside top front of the twonose cowl airflow inlets so that they could not be seen and used finishing resin to adhere the two 4 ounce lead weights to the inside of thenose cowl. I used DU-Bro Heavy DutyPost Control Horns and linkages,DU-Bro HD PULL-PULLfor the Rudder and(7) Hi-Tec645 MG Servos, Spectrum AR7000 Receiver. Iused the 7th servo for the choke which I run off of the GEAR Channel lever. The SIG 500MM fuel tank was moved back (1) one inchand held in place with two small bungees with eye hooks, this had to bedone because using the opening of the firewall holefor the fuel tank stopperwould cause too much of a bend in the TY-GON fuel lines. With all thisbeing said:
THE MANUFACTURERS CG OF 27% WAS PERFECTWHICH IS EXACTLY 4 INCHESFROM THE LEADING EDGE ALONG THE SIDEOF THE FUSELAGE.
THE FIRST TWO FLIGHTS WERE YESTERDAY AND THREE FLIGHTS TODAY. I USED ONLY 4 CLICKS OF UP ELEVATOR, 4 CLICK OF RIGHT AILERON ANDTHE AIRPLANE FLEW HANDS OFFAND WHEN INVERTED, ITWANTS TO CLIMBSLIGHTLY, WHICH MAKES FOR A PERFECT SET UP. Initially I thought the 20 DLE GAS engine was going to make it under powered, but it will do all of the IMAC manuevers without effort.....It likes to land a little long bec ause the engine idle does not settle down right away when landing do to too much residule fuel still in the chamber with an inverted engine. But it is very gentle and forgiving on Take Off and Landings and does not show any wing tip stall tendencieswhen landingassociated with the CAP's.............Sonny Silvaroli
