Pipe Header Assembly

1. Recommended header length for MTW RE3 tuned pipe
and DA-170 is 14 inches. Assemble the pipe/header using a
vice-grip. Open the clamps and slide them over the header.

2. Insert the header and pipe into coupler, leave 1/8--1/4
inch gap between header and pipe. Slide the clamps on the
20
pipe and header, such that is it forward the bump on the
header and over the grooves on the pipe/canister.

3. Once everything is assembled, heat the couplers where
clamps are using a heat gun at high setting. Do this for a few
minutes and allow some time for cooling. Repeat this one
more time. This will create a good grip and reduces chance
of pipe/header slipping out in flight. It is also recommended
to do this before the first flight. Let engine idle for 3 to 4
minutes to warm up the couplers, gradually increasing the
throttle to half to get the engine hot and then allow a cool-
down period before the first flight. This should not need
repeating and when done right, header/pipe will not slip out.
Canisters Mount Installation

1. Kit comes with 2 canister mounts and silicone tubing.
There is only one support location for the canister mount
that is under the landing gear area. Scratch the surface of
each mount with a hobby knife and glue the layers using a
thin layer of 5 to 15-minute epoxy. Clamp until glue is cured.
Pass the silicone tubing through the mount start with top
middle hole and end at bottom middle hole as shown in
Pipes Mount Installation section.

2. Prepare the fuselage for canister installation. Remove
the covering as pictured in first bay, under the landing gear
and iron down the edges.
