4. The very special hatch design allows us to remove the entire nose of the airplane, shortening it
for transportation without having to spit the fuselage in half behind the engine. That way we
keep the closed ducting together and eliminate the additional weight of a joint behind the CG.
Just as much as we tried to avoid prominent servo hatches, we successfully avoided a large
engine hatch, too. Instead we designed a unique way of installing the engine permanently in
the carbon bypass and then inserting this complete assembly, including thrust tube, through
the back of the airplane. Once the complete system is installed, the engine is accessed,
removed and re-installed, through the removable bypass cover and through the top opening in
the fuselage, as narrow as it may seem.
5. Last but not least, with clever weight distribution we were able to put the fuel exactly on the
CG, still keep the tail light, having lots of options to move heavy equipment in the very front of
the airplane, thus allowing a pretty long tail moment for a sport jet of this type. That gives you
the rock solid, locked in feel in the air, even at highest speeds. A full carbon fiber build, the
one-piece stab, the 30 mm (!) carbon fin tube and the 40mm carbon wing tube, together with
the carbon sheeted internal structural parts make the CARF-Models BOLT! stronger and stiffer
than any other jet, taking even the hardest abuse without wear, tear or failure.
Now, admittedly, these are a few very special design features. But - let it sink in, try to understand
the philosophy behind it and enjoy the clean way of building a highly engineered and extremely
advanced sport jet. Boredom is not on the agenda when building a CARF-Models BOLT! Follow
this manual, do not change things, simply go with our advice and our recommended equipment
and accessories and you will have a blast building this airplane to the highest standards of what is
possible today. And the joy flying it will be endless.
What you need to complete this build:
Listed CARF-Models BOLT! accessories:
1) CARF/Electron BOLT! electric landing gear with wheels, brakes and GS-200 controller
2) CARF Kevlar saddle tanks
3) CARF Kevlar smoke tank
4) CARF double walled spiral reinforced stainless steel thrust tube
3rd party accessory recommendation:
5) 7 pcs 20mm standard servos with approx. 25 kg torque (aileron, elevator, main gear doors and
nose gear steering, e.g. MacGregor 6928 HV or SAVOX 2071 HV))
6) 3 pcs 20/21mm standard servos with approx. 35-40 kg torque (flaps and rudder, e.g.
MacGregor 8346 HV or SAVOX 2290 HV)
7) 1 pc 15 mm mini servo with approx. 8-10 kg torque (nose gear door, e.g. MacGregor 2810HV
or SAVOX 1061)
8) 11 metal servo arms 25 mm (1")
9) Cortex Pro or iGyro (this depends on your your preference and what radio system you're going
to use)
10) A Power distribution system like Powerbox Mercury, Professional, Jeti Centralbox 210/220
11) A 220 - 260 N turbine engine (we use the KingTech 260 G2 but can recommend Frank Turbine
250, JetCat 220, 250, etc
12) A set of high quality connectors for the joints between the main fuselage and nose cone,
wings, stab and fin. We strongly recommend to build your wiring harness by using the high
quality Powerbox servo wire and their crimping accessories
13) Powerbox Smoke Pump
14) Some good CA glue and high end 2 component glue like Hysol, Aeropoxy or UHU Endfest
300.
15) Good hand tools, a dremel grinder (or similar) with diamond disk and sanding drum (a long
2.5mm allen key is included in the kit)
16) A pair of reading glasses, in case you have difficulties to read these instructions - because
you are absolutely going to need to understand and follow these to build your BOLT!
