Construction / tuning:

Despite the fact that I did not have too good experiences with the first
LRB plane (Jet Stream Type G) I opted to go for this special offer at the
shop - Ready to fly with all in for only 100 EUR! I could not resist and
ordered the Jet Stream Type B7.

The name I guess shall give a resemblance to the Boeing B 777 - but...
well, just with lots of imaginations.

Nevertheless - once the box arrived I opened it with anticipation. This
time actually the parts were in better condition then the first plane. The
foam was good quality (Styrofoam) and the wings were not bend.
The remote (FM 35 band) & charger were ok for an RTF box.
All parts were well secured in the box and nothing was damaged.
A bag with small items was also included as was a larger sheet with
decals!

A few things I changed/added during the assembly:

- the receiver was replaced with one of my Futaba 2,4 GHz ones.
- the wing fixings in the fuselage were enforced with additional epoxy
- the servos were fixed in addition to the wobbly double tape with hot    
glue
- the fans were attached and glued in place with epoxy
- the lipo plug was replaced with one that fits to my other batteries (MPX  
  plug system)
- a 2 mm CFK support rod was run on the underside of the wings and
was fixed in place with epoxy glue.
- I applied the decals BEFORE fixing the elevator & rudder - this is much
  easier at this point in time, then when the plane is already assembled.
- Last but not least I changed the BEC-battery plugs to my standard MPX
  types

Otherwise I followed the instruction manual.

I was surprised to find the plane substantially heavier as indicated by
the producer.. well, just a bit extra hot glue & epoxy... but almost 80 g (20
% more) I find excessive. Lets see how the flight performance will be
influenced by that!


Flight Experience:

Still to come.

Flying Time:
- with my battery as above: approx. 4 - 6 minutes
