❑
1) a. Insert one of the M4 x 34mm PWA Axle Bolts through the
hub of one of the 2-1/4" dia. Main Wheels. Slide the wheel all the
way up against the head of the bolt.
b. Next thread a M4 Lock Nut onto the threaded end of the
bolt, and run it all the way up to the wheel - but not too tight - the
wheel must turn freely.
c. Now thread a M4 Hex Nut up tight against the Lock Nut.
This hex nut serves as a spacer to keep the tire from rubbing on
the wheel pant after it is installed.
d. Finally, insert the threaded end of the axel bolt through the
aluminum landing gear leg and install another M4 Lock Nut on the
inside of the landing gear leg. Tighten securely.
e. Repeat this proceedure to install the other wheel onto the
opposite landing gear leg.
❑
2) Mount the Fiberglass Wheel Pants to the landing gear with
the M3 x 10mm PWA Bolts and M3 Split Lock Washers provided.
Tighten securely. Double check to make sure that the wheels turn
freely without obstruction.
❑
3) Bolt the main landing gear assembly onto the bottom of the
fuselage using the M4 x 15mm PWA Bolts and M4 Split Lock
Washers provided. Put a drop of thread locking compound, such
as Locktite
®
, on the threads of the bolts before screwing them in.
alignment and prop clearance purposes.
Accurately mark the
engine's mounting bolt hole locations onto the engine mounts.
Then set the engine aside.
b. Drill the four engine mounting holes completely through the
mounts. Be very careful to drill them perpendicular to the mount.
Use a drill press if available.
c. Mount your engine in place on the engine mounts. We
suggest using a little thread locking compound (Loctite
®
) on the
mounting bolts to keep them from coming loose.
Note: This kit DOES NOT contain bolts for mounting your engine
to the engine mounts. That's because not all of the engines that
can be used in the Mayhem use the same size bolts.
Some
engines may need 4-40 size bolts, while others may need 6-32.
You will need to go to the hobby shop to obtain the correct size
mounting bolts for your engine..
FUSELAGE ASSEMBLY, PART II: Main Landing Gear
For the following steps you will need these parts:
•
The fuselage assembly
•
1 - Aluminum Landing Gear
•
2 - M4 x 15mm PWA Bolts
•
2 - M4 Split Lock Washers
•
2 - 2-1/4" dia. Main Wheels
•
2 - M4 x 34mm PWA Axle Bolts
•
4 - M4 Lock Nuts
•
2 - M4 Hex Nuts
•
1 - Right Fiberglass Wheel Pant
•
1 - Left Fiberglass Wheel Pant
•
4 - M3 x 10mm PWA Bolts
•
4 - M3 Split Lock Washers
Note: When assembling the hardware in the following steps, we
recommend that you use a thread-locking compound, such as
Locktite
®
, to keep the parts from vibrating loose in flight. It only
takes a small drop, placed right in the threads of the mating parts,
to keep them tight and secure.

IMPORTANT SAFETY ISSUE!
DO NOT DRILL AND TAP THE GLASS-FILLED ENGINE MOUNTS
FOR BOLTS, OR USE SELF-TAPPING SCREWS OR WOOD
SCREWS.
THOSE METHODS WILL WEAKEN THE ENGINE
MOUNTS AND CAN LEAD TO ENGINE MOUNT FAILURE!
1) Use only Socket-Head Bolts with Aircraft Lock Nuts and Flat
Metal Washers to fasten your engine to the glass-filled engine
mounts, as shown in these instructions.
2) The holes you drill through the mounts must be big enough for the
engine mounting bolts to pass freely through. The bolts should not go
in tight. In the case of 4-40 mounting bolts, a 1/8" dia. drill bit will
provide proper clearance holes. For 6-32 bolts use a 5/32” drill bit.
