Aero Resources, Inc. (ARI) is marketing Landing Gear Modifications from three different manufacturers: Knots2U,
Lake Aero Styling and Repair (LASAR), and Laminar Flow Systems, Inc. The landing gear mods from Knots2U
include nose gear and main gear pants for fixed gear Cessna models, nose gear and main gear pants for Piper
models, gear lobe fairings for Piper retractable gear models, flap/landing gear alert systems for Piper Comanche
PA-24/30/39 models and Beech 33/35/36 models, and a wheel pant hardware/bushing kit. The landing gear mods
from LASAR include a wheel well liner kit, a brake wheel cylinder rotation kit, a nose gear truss oversized bushing
kit, and a steering horn assembly kit for Mooney airplanes. The landing gear mods from Laminar Flow Systems
include nose gear and main gear pants for Piper fixed gear models, wheel well fairings (similar to Knots2U gear
lobe fairing) for Piper retractable gear models, and mounting hardware for fixed gear pant kits. A brief description
of each type of landing gear mod will be provided below. The Knots2U kits are distinguished by "K2U" in the part
number, Lake Aero Styling and Repair by "LAS" in the part number, and Laminar Flow Systems by "LFS" in the
part number. Click on your aircraft make above to find the available mods.
GENERAL DESCRIPTION OF EACH TYPE OF LANDING GEAR MOD
Cessna Nose Gear and Main Gear Wheel Pants
The Cessna nose gear and main gear pants by Knots2U are the cleanest design on the market. Brake fairings for
the main gear fit flush and attach using 1/4 turn Camlock� fasteners for removal in seconds. Hinged doors are
provided for quick tire pressure checks. All three wheel pants are assembled in two pieces, allowing removal of
the pants without having to remove the tires or raise the aircraft. Parts are made of high quality hand laminated
fiberglass for superior strength and long life. The sleek design eliminates the ridges found on the Cessna OEM
pants and offers improved aerodynamics, which Knots2U estimates will add 4-9 mph to the aircraft. The nose
wheel pants come in two versions, one with 5.00 X 5 nose tires and the other for 6.00 X 6 nose tires. The main
wheel pants also come in two versions, one for 6.00 X 6 tires and one for 8.00 X 6 tires. The main gear also
come in versions for early model spring gear and later model tubular gear Cessnas at the same price.
The Piper nose gear and main gear pants by Knots2U are approved for most PA-28 and PA-32 Models built before
the 1978 model year. They are made in one piece of durable fiberglass using the latest in resin technology for long
life and premium fit. They are FAA/PMA approved as replacements for the original nose and main gear pants. The
nose gear pant is for 6.00 X 6 tires only. The Knots2U Main Gear Fairing kit attaches to your existing wheel
pants and covers the brakes, torque links, brake lines, and struts while maintaining a small sleek profile.
In addition, a fairing is supplied to smooth the strut into the wing. Knots2U estimates the fairings will
add 5-6 mph in cruise speed as well as a slight increase in climb performance. The fairings are made of high
quality hand-laid fiberglass with Kevlar reinforcement at all the attachment points. They remove easily for
inspections and maintenance. This aerodynamic lightweight modification comes with all stainless steel hardware
and complete step-by-step instructions. Unlike the later model Piper fairings, these are much smaller and have a
total weight of only 5.9 lbs. This main gear fairing kit installs in about 9 hours.
Laminal Flow Systems (LFS) produces a nose gear fairing for Piper Cherokee fixed gear models which creates a
tear drop shape around the lower nose strut and block, thus reducing the drag coefficient around the gear. It is
installed in about 2 hours by attaching it to the existing nose gear pant. It is finished in gray primer and ready to
paint with all hardware included, as well as instructions and STC. LFS estimates a speed increase of 2-3 mph.
LFS has a Fancy Pants mod for the main gear (similar to the Knots2U fairing kit) which covers the brake
and strut parts of the landing gear. The Fancy Pants attach to the existing wheel pants and can
be installed in about 4 hours. LFS estimates a speed gain of about 6 mph.
LFS also produces a Speedpants kit for the main gear of the Piper Cherokee fixed gear models which includes
new main gear pants. The company has a version of the kit for Pre-1978 models and Post-1978 models. On the
Pre-1978 Piper Cherokee models, the main gear pants, strut fainings, inboard mounts, and vertical mounts are
required to install the kit. On the Post-1978 models, only the main gear pants are required to install the kit.
The outboard stub axles (2), which are optional for both versions, are only needed if the originals have been lost
or damaged. LFS estimates an 8 mph gain over the original Pre-1978 Piper pants and up to 3 mph gain over
the original Post-1978 Piper pants. Both versions are STC/PMA approved and the Pre-1978 version installs in
about 6 hours and the Post-1978 version installs in about one hour. Speedpants are covered by a
"no-questions-asked" 100% money-back guarantee for 90 days. Additionally, they are guaranteed against
breakage (unless caused by accident) for 1 year or 1000 hours (whichever comes first).
Piper Gear Lobe Fairing/Wheel Well Fairing Kits
The Knots2U Gear Lobe Fairing kit smoothes the air from behind the retracted main landing gear of most Piper
retractable gear models. Depending to the aircraft model, Knots2U estimates a speed increase of 3-5 mph. The
gear lobes are made of a composite shell filled with a "closed cell" urethane foam to keep them rigid in flight and
moisture free. They have a "teardrop" shape with hidden attachments and can be installed in about 4 hours. The
Knots2U kit is approved for Piper PA-28 and PA-32 Cherokee retractables, the PA-34 Seneca, and the PA-44
Seminole. The kit includes all the parts necessary for installation and is fully STC'd.
Laminar Flow Systems produces a Wheel Well Fairing kit which is very similar to the Knots2U Gear Lobe Fairing
kit, except it is made of aluminum instead of composite material. It is approved for the Piper PA-28 and PA-32
Cherokee retractables and the PA-34 Seneca. LFS estimates a speed increase of 3-4 mph and an installation
time of 3 to 4 hours.
Mooney Landing Gear Mods
Lake Aero Styling and Repair (LASAR) produces landing gear modification kits exclusively for Mooney aircraft. The
Wheel Well Liner kit is approved for M20B thru M20K Models. It reduces the turbulent air flow in the wheel wells
and provides a barrier for mud, debris and mice. LASAR estimates a speed increase of 1 mph and as installation
time of about 4 hours.
The Brake Wheel Cylinder Rotation kit is approved for M20B thru M20K Models. This kit is an STC which reverses
the brake calipers out of the slip stream when the main landing gear is retracted. LASAR estimates a speed
increase of 1 mph and an installation time of about 4 hours.
The Nose Gear Truss Oversized Bushing kit is approved for M20 thru M20K Models. It resizes your worn truss
to restore the nose gear pivot to the proper tolerances and eliminate nose gear shimmy. It installs in about 2
The Steering Horn Assembly modification is approved for M20C thru M20S Models. The new PMA'd steering horn
by LASAR has fewer moving parts and requires less maintenance. It features life time aluminum/bronze bushings,
heat-treated T-Shaft, and a new clamp-on pivot stud for positive alignment. You may also be eligible for a core
discount for your old parts. The kit installs in about 3 hours.
Flap/Landing Gear Alert Systems
This Flap/Landing Gear Alert System by Knots2U puts an electronic circuit between the flap switch and the landing
gear switch. If the landing gear is not down and locked the system triggers the existing gear warning horn, plus a
new "GEAR ALERT" light the instant the flaps are selected for the down position. With this system you get the
warning in the pattern, not a few feet off the ground! With its new "push to test" function you can test even the
aircraft's stock warning system at any time. The existing throttle actuated gear alert is kept intact for added
The kit is available for all Beech 33/35/36 models and all Piper PA-24/30/39 models. The PA-24 models with
manual flaps use a micro-switch connected to the flaps that can be set to trigger the system after the first notch
of flaps. All models, except the PA-24 manual flap models, install in about 4 hours. The PA-24 kit for manual flap
models installs in about 6 hours. The kit is STC/PMA'd and comes complete with everything necessary for
