FAUX CAT (Scratch Built Bell Hop) 
Electric Powered Non-Electric Powered
MODEL FAUX CAT (Scratch Built Bell Hop)
ENGINE: DLE 35 ra
RECEIVER: Spectrum AR6210
SERVO: HD-1501MG
TRANSMITTER: Spectrum DX7S
PROP: Xoar 19x8
MODIFICATIONS: Feb 27, 2011 - Started project. Original Bell Hop was a 40" wingspan electric plane. I redesigned it to be an 86" wingspan, 30cc Gas model. It was finished on April 26, 2016. I added 3 degrees of washout to the wing to help with the low-speed handling. The plane is great at low speed. The plane fly's great, it is also not a floater, it lands like it has flaps. The DLE-35 is plenty of power, most flying is done at 1/4 throttle. A smaller engine could be used, but then some weight would be required in the nose to balance the plane. I originally planned to have the servos mounted in the tail, but I had to move them to the mid-fuselage to balance the plane without adding nose weight. The elevators are controlled by one servo with a fiberglass rod and "Y" connector. The rudder is "pull-pull." See detailed construction on Bell Hop RCU thread. The model is painted to resemble (sort of) a WWII warbird.


Great Planes Giant Super Sportster 
Electric Powered Non-Electric Powered
ENGINE: DLE 35 ra
RECEIVER: Spectrum AR6210
SERVO: Hitec HS-645MG (Ailerons)
SERVO2: Hitec HS-645MG (Elevator)
SERVO3: Hitec HS-485HB (Throttle)
TRANSMITTER: Spectrum DX7S
FUEL: 87 with 10% Ethanol with Stihl Ultra HP at 30:1
PROP: 19x10 Xoar
MODIFICATIONS: Note: The servos I am using on the ailerons and rudder are NOT recommended for use with gas engines because they do not have metal gears. They are also not recommended for planes over 12 lbs even with one servo per control surface. I am using servos with metal gears on the elevator due to past problems with flutter. I am using heavy duty control horns on the servos. Used Blue hinges instead of GP hinges. supplied with kit. Update - Replaced them with the 3/16" Robart hinges due to breaking and flutter problems. Used brass tubes in the wing instead of wood dowels supplied with kit. Moved landing gear from wing to fuselage. Saw several wing mounted gear failures. Used LG from the .120 sized Spacewalker II. Added springs to beef up gear and to prevent bending. Reduced fuel tank size to 12 oz. Sept 2010 - Replaced control surface linkages with Dave Brown fiberglass 1/4" ID shafts and Du-Bro 4-40 Swivel Ball Links. No problems with the original hardware with over 350 flights. Just think the new links look better. RIP - Oct 7, 2010 - Right Stab departed aircraft, followed by rt elevator. Left elevator came loose but stayed with plane till impact. Cause was determined to be a break in the right hand stab near the control horn location. The wood split which allowed the pined hinge to slide out and the resulting elevator flutter caused the fixed stab to depart the plane followed shortly by the elevator after the servo rod separated. IMO when powered with "hot" 30cc or larger engines, the horizontal stab needs more wood,harder wood, or flying wires. Added tail bracing, tried kevlar and wire, but wound up with carbon fiber rods with 1/16" fittings. Oct 2011-Got tired of minor fuel leaks. Replaced fuel tank with B&B Specialties 16 oz tank. The fittings are installed in the tank by drilling holes where you want them and they are held in place with nuts for a leak proof fit. The fittings have large barbs to prevent fuel lines from slipping off. Nov 23, 2011 - The rudder servo failed on Nov 23, 2011, it was a Hitec, HS-485HB, which is not recommended for Gas models. The gears are okay, the failure was electronic. I replaced it with a Cirrus CS704/MG. Mar 28 2012 - Had one of the HS-485HB servos fail. Electrical problem, not mechanical. Replaced both of them with the HS-645MG type. Had about 1900 flights on the plane to date. Feb 17, 2013. After about 2,600 flights and over 25,000 landings, the main gear broke from all the bending. Replaced it with the Great Planes Main Landing Gear from a Giant Big Stik ARF. I got it from Tower Hobbies. May 13, 2013 Replaced the Syssa SAP 180 30cc engine with a DLE 35 ra. About the same power, runs great, better customer service. My CG is 6-1/4".
