  • Page 1 Glow or Electric Power. A manual of the Valiant’s designer Bryan Hebert. Bryan has written the CARF Valiant Manual while installing a YS 170. As an additional contribution to this manual Stuart Chale has written up an installation manual for an outrunner electric installation.
  • Page 2 If you’re reading this you must be open to new ideas. I’m going to try to give the best information I can on the new Comp-Arf models Valiant to help with the building, set up and trimming of this one-of-a-kind F3A Machine.
  • Page 3 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com First some important information The weight balance of the Valiant was designed to accommodate most motors with, some adjustment of the center of gravity (C/G) being needed on others. If you are flying Glow or Electric, the stabs are cut out for Mini servos, and these servo’s can be in- stalled in the stab halves, with little adjusting of C/G required to complete final balance in the radio installation process.
  • Page 4 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Motor mounts I recommend the LR 85 Hyde mount for this airplane. I worked with Merle Hyde on the application and operation of this mount, having tested all of his mounts on this airframe, and finding the LR 85 to be the best overall for my composite designs.

  • Page 6 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com using an applicator or a brush, apply the glue to the firewall. When the firewall glue is completely hardened, drill the holes in the motor mount through the firewall and install the blind nuts. Relieve the flashing on the engine compartment so the motor can- not touch or rub.
  • Page 7 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Cowling with Quick disconnect You can use your own method of install- ing the cowling for the glow version. The rear pins are already installed at the factory, with a front screw in place.

  • Page 9 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Landing Gear Assemble the gear using Central Hob- bies™ aluminum axles, or equivalent, to keep the weight down. Make sure you use Loc-tite™ or some other thread lock compound on the axle screws to pre- vent the threads from backing off and losing the wheel and pant in flight.
  • Page 10 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Now let start on the Canopy. #1 Install the supplied hooks a little beyond the middle of the canopy facing forward, using a thixotropic epoxy mix. #2 After this is hardened, measure and cut receptacle holes for the hooks in the fuse side canopy flashing.
  • Page 11 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com #5 After the rear latch is hardened, install the canopy. Find the rear pin indent and drill the hole for the rear latch pin. #6 Using a Dremel™ barrel grinder, drill a hole towards the front of the canopy through the top skin.
  • Page 12 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Now to the rudder tray #1 Test fit the tray, in the rear edge of the canopy opening. It will need to be cut down slightly to fit the fuse properly (warning do not force fit; it can ruin the...
  • Page 13 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com to mount a tail wheel, so drill through the bottom of the fuse into the hard point installed, to mount the tail wheel. The rudder however does not have a hard point; it will have to be added if you want a tiller arm attachment there.
  • Page 14 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Fuel Tank formers and rear former These formers are installed for two reasons; fuselage rigidity, and as a trouble free tank mount. Once installed, they cannot be removed; so, install them such that the tank is centered on the wing tube.
  • Page 15 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Installing the elevator control arms and elevator halves I recommend using the control horn provided in the kit for elevators, because we will use a MK ™ BB adjuster end on the elevator half, and on the servo side.
  • Page 16 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com #1 Trace the outer stab root, on some 2- 3 mm light balsa wood and, after you trim it to fit inside the stab flange flash- ing, cut some lightening holes, for servo wire access. Use some 5-minute epoxy and glue it in place.
  • Page 17 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com For longevity we will use a wood dowel sunk into the hard points in the ailerons, with a 3mm or 6-32 standard stud tapped into the hard points. This will give you more options on the BB clevises manufactured by MK™...
  • Page 18 (A mid rate rudder). Again, adjust the rudder if you can’t cleanly exit (over rotate, reduce rudder and vice versa. The rudder is very powerful and the Valiant can do a knife-edge loop easily on low rate rudder. However, the fin and rudder were designed for a perfect snapping balance, and you will have best stall turn results on high rate in windy or calm conditions.

  • Page 19: Electric Motor Installation

    CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com Electric motor installation: There are two basic types of electric motor installations. Firewall mounted for outrunner motors like Axi and Plettenberg, and nose ring mounted with a rear support for inrunner motors like Hacker and Neu motors both with reduction gearing.
  • Page 20 There is no air outlet from the fuse so ex- haust holes have to be cut. Any design or pattern will do as long as they are large enough. The Valiant has a nice ridge molded in the bottom of the fuse that adds additional Page 20...
  • Page 21 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com strength compared to a simple rounded bottom. I would recommend not cutting into this ridge for that reason. Keep your cooling hole pattern symmetric to either side of the ridge. Battery tray: The battery tray can be made from the included piece of balsa laminated with fiberglass.
  • Page 22 I recommend flying the Valiant for a while before installing the Strake to feel how well it actually works. You will be amazed at how well this simple devise works.
  • Page 23 CARF-Models Co., Ltd, Contact email: techsupport@composite-arf.com #3 Carefully place the strake on the glue line, hold it in place and let it set ,after the glue sets on the base, glue the upper portion to the fin. #4 Set the fuselage on a stand. Using an incidence meter set the fuse to zero measur- ing from the canopy base.
