Part of the building chore is laying out the servos and control system. This is a dual SUKHOI model (only one of the fuselages is shown). Servo location, servo type, and control system type (push rod, pull-pull cables), can be selected to help balance the model. Seen here are three servos, all of different manufacture. A Royal standard is used for the throttle on the OS Surpass 70 (one for each fuselage). A Futaba 9101 is used for the rudder (not fully connected yet). A HITEC HS615 metal gear is used for the Elevator. Carbon fiber push rods are used for moving the rudder and elevator. Note the strain relief on the receiver antenna wire. |

The Hots design has been around for a while. This is the Big Hots with a Tartan Super Twin Glo engine. The engine burns lots of alchol, but doesn't suffer the problems of its heavier gasoline brother. The plane's speed envelope is pretty large. Because of the large thick wing, it will slow down to a walk. |

This is a Taylorcraft being rebuilt. A problem landing broke the wing spars and cracked the windshield. It is about 60% rebuilt, this time using a US Engines 41 cc (2.5 Cubic Inches) gasoline engine. The underpowered Sachs 2.0 really wasn't enough to make this plane as much fun to fly as was expected. |

A shot of part of the wing of a Ziroli F8F Bearcat being built. The servos for the ailerons are in the access bays and the Flaps have servos mounted in the middle of the wing. The DAD reflex high torque servos are used for each control surface. |

A lot of the photos are from the Hangar/Shop area. Seen here is the Ziroli F8F fuselage under construction. It has the 3W 120B2 (7.95 cubic inch twin) engine up front. The landing gear will be fixed on this plane. This simplifies the building and takes some of the complexity out, but ruins the scale effect. I doubt the additional drag will be a problem during flight. In the background is a Sky Master Industries Super Lazy Ace biplane fuselage. More on that model later... |

This is a WarZone Models Combat 704 F8F Bearcat under construction. This was one of the first kits sold after the business changed hands to Larry Root. A few things made this more than a challenging kit to build. Larry has made corrections and makes a top quality kit. (716) 227-0592 Seen here are the blue foam fuselage with the spackling compound used to smooth out the foam. Carbon fiber was used in the longeron slots and carbon fiber mat was used between the foam and the balsa stiffeners inside. Shreaded carbon fiber was also used to strengthen the firewall to fuselage joint. Even with all these changes, the model will weigh less than 2.2 lbs! |

This is the rest of the kit parts, still under construction. Robart hingepoints will be used on the ailerons. The wings were planked with 1/16-inch balsa and sanded, carbon fiber was added to the spruce spar slots (beforehand of course). The 1-1/2 inch dihedral has yet to be sanded into each root of the wing panels, the root ribs need to be glued on and then fiberglass reinforcment added after the wing panels are epoxied together. Tail feathers are solid balsa. The rudder will be controllable on this model. RCD HS-85 servos will be used for the control surfaces (the aileron servos are in each wing panel) and a RCD HS 80 for the throttle on the MVVS 0.21 two stroke. |
