The EDF UCAV from Nitro Planes is a large fiberglass jet model with sheeted wings. It comes complete with landing gear, fiberglass canopy, missiles, and all hardware. The model can be powered by a 90mm to 101mm ( 3.5" to 4" ) EDF unit.

The fuselage and parts come well secured in the custom box. All the parts are
covered in plastic or bagged. The control surfaces arrive attached with hinge
material but need to be CA'ed in place after alignment.
The fiberglass canopy is pre-finished and only needs the latch mechanism
attached. The landing gear are fixed with a steerable nose wheel assembly. Two
sheets of finishing decals are supplied and the 7-page manual, although sparse,
provides sufficient photos and text to complete the model by an experienced
assembler.
A closer look at the fuselage reveals the size, quality finish,
construction techniques, and high level of pre-assembly. The T-nuts are already
installed, and glued in place, for the gear mains and steerable nose wheel
assembly. The
battery and servo trays are also pre-installed.
My Nitro UCAV was Ready-To-Fly at 8.5lbs. The empty plane weighed
100oz (6.25lbs) and my two 6s EON packs weighed 36oz (2.25lbs) together. The
3300 watt power system provides a powerful 390w/lb!
We had some good success with our first test flights on the Nitro
UCAV. The power system was awesome and had no problem taking off grass.
After landing hard on the first few flights, we moved the CG from 7.25" to
7.75" and had much easier take-offs and landings.
The UCAV
flew very stabile, even when it was flown slower. The EDF jet performed
loops and rolls with ease. We discovered that when landing, you need to
carry a certain speed or the plane will pitch up if it lands too slow. The
pitch-up is due to the fact that the V-tail stops flying first when the air
flow is low and simply drops.
I did
permanently glue on the wings for added structural integrity. The rather
soft landing gear act as shock absorbers on those less than perfect landings
and they are easy to bend back in place after first removing them from the
fuselage. We left the nose gear bent backwards as it seemed to still
take-off and land well until I finally replaced it with the Dubro 5/32"
Universal Nose Gear Wire. The coil spring in the nose gear still works when
the gear is bent back.
The second
video shows continued success with the UCAV. Perhaps over the
winter, I'll look into
beefing up the gear mains mount and replacing the stock nose wheel with a
retractable Robart strut.
The fact that the aluminum gear mains bend upon hard impact is a real plus
as it absorbs those less than perfect landings.
The UCAV was a very fun project and exceeded my expectations for a
larger EDF model without breaking the bank.
