Roy Maynard’s Northrop F-89
Scorpion Project |
|
Roy shared
an update on his
F-89 Scorpion (last seen at our
Nov. 2019 Newsletter/Meeting).
This out of production 1/6.5 kit
is from Air-C-Race in Germany.
This 106” wingspan model is
highly detailed and comes with a
lot of prefabrication.
This was the first time Roy had
assembled the airframe and it is
big! |
|
 |
|
All surfaces are
pre-hinged and the servos drop
in. It will be fitted with
a single turbine (Xicoy 180N)
and a Tamjets Y-intake pipe.
The retracts are electric and
from Behotec and a nomenclature
file was provided with the kit.
Roy had prepped
the panel lines and used flush
rivets from Chad Veich. He
did a paint match using FDC
paint
chips for ADC
gray. He’s ready to add color
for the Minnesota Air National
Guard markings. The
current weight is approx. 37#
before finishing and the final
radio gear. He expects a maiden
flight by June 2027. |

Jan Larsen’s
4M Motor Glider Project
|
|
Jan
assembled his 4M span (157.5
inches or 13.12 feet) motor
glider and described the unique
power system and control
features.
Jan worked
with Ahmed Bassal to
calculate the most efficient
Motor, Esc, and Battery
combination using components
from BadAss Motors. |
 |
|
High KV
(880) able to go from 6S to a 3S
battery (9000mAH) gives 25
minutes flight time, 9# weight,
72 mph at full power.
Czech kit
Xyprus? Roy Maynard
and Ahmed have same
plane. Jan has 10 flights
to date
and it's capable of spot landing
in a European competition.
Larry S says there are 5
or more competitions in
Minnesota, South Dakota and
Arizona.
The aircraft
has a full flying horizontal
stab, full wing combined
flaperons & upper wing spoilers.
Jan is uses a FrSky radio. |

Mike Davis Bates Douglas SBD-3
Dauntless Update |
|
 |
|
Mike
purchased an SBD-3 Dauntless
project at a swap meet a few
years ago. It requires a
set of retractable landing gear.
Mike
connected with Darren Bitzer
(Century Jet Models) for a set
of CMJ gear. Darren
delivered the set to Mike at the
meeting. We look forward
to seeing Mike’s progress on the
project this winter! |

Darren Bitzer’s Century Jet
Models
Down & Locked Electric Retracts |
|
Darren
shared some of his new electric
retracts created from a
partnership between CJM and D&L
retracts. Contact Darren
for information and
availability!

Karl
Hansen 3D Printed Scale RC Models |
|
 |
|
Karl Hansen
showed a couple of projects in
progress. He had been working
with KEDY Studio who is selling 3D
Print files of 1/6th scale Warbirds
and models. Karl showed his
Me-109E (about $60/file set) and
T-28 Trojan components.
Designed for
electric power and commercial
retracts and most radio systems.
Lots of detail including panel lines
and rivets on the surfaces. We
look forward to seeing the finished
project! |

Pedro Restrepo’s 1/6th Scale, Dave
Andersen Designs Grumman Lynx
Project |
 |
Pedro shared
information on his ‘Baby Lynx’
project. Pedro has reduced his
Dave Andersen’s Gumman Lynx Plans to
1/6th Scale for this electric build
project. He’s had some problems with
the nose gear since Robart has
closed its doors.
He’s rescaled
the nose gear and made most of it
from music wire, but was finding the
nose wheel yoke a challenge in
design and materials selection.
Aluminum is too soft. |
|
Pedro found an
on-line source for custom 3D printed
METAL components. They took
his design files and printed a
prototype fork using TITANIUM!
They printed it and sent him the
prototype in 2 weeks! He found
that he could substantially reduce
the thickness (due to the strength
of the Titanium) and have a much
more scale wheel fork! |
 |
 |
 |
|
The end cost of
the 3D Printed Titanium Whe el
Fork was less than $20 USD shipped
(from China to Bloomington, MN!).
You can contact Pedro concerning his
source and his experiences with
them.
We’ll look
forward to hearing more about his
project! |

Larry Sorensen’s
ToolKitRC M6D AC/DC Field Charger |
 |
Larry shared his experience with the
field charger from ToolKitRC.com
that he uses for topping off his
flight batteries on his turbine
powered jets at the field.
Jan Larsen & Ahmed Bassal
have been using them for over 4
years with no problems. Nice Tip!
