Occasionally we will make reference to the plan in order to clarify the instructions. We have letters down the side and num-
bers across the bottom of the plans. In brackets [ ] we will give you the coordinates like a road map to locate the item
referred to. Find the letter and number and where they cross will be the location to look.
When working over the plan, waxed paper should be used to protect the plan and eliminate other frustrations caused by
parts sticking to the paper and the additional sanding involved.
If you plan on building the Taildragger version, please follow the taildragger add-ons listed under the appropriate sections.
Our prototype Tri-gear version required 4 oz. of tail weight with the battery moved to the back of the fuselage servo
tray. The plane was setup with a .46 engine and standard muffler. Be sure to account for this when building. The
Taildragger version should not require any additional tail weight.
1. Find vertical fin (MS401, MS404), elevators
(MS403), horizontal stab (MS405) and rud-
der (MS402) parts.
2. Over the plans, join MS405 to the 1/4” x 3”
x 24” balsa sheet with thin or medium CA.
3. Join MS401 to MS404 so they align with
the plans. Use thin or medium CA.
4. Remove above pieces from the plan and
mark a center line on the leading edge of
both elevators (MS403) and rudder
(MS402). Do the same on the trailing edge
of the fin and stab assembly.
5. Place a mark on these center lines indicat-
ing where the hinges and elevator joiner
wire are to be located. See plan [B24 &P24].
6. With a 3/32” drill bit, drill a hole in each ele-
vator (MS403) half approximately 3/4” deep
to accept the elevator joiner rod. Cut a
groove from these holes on the front edge to
the inner end of each elevator half to allow
the joiner rod to fit flush with the elevators.
Put a few drops of thin CA in the drilled hole
and re-drill with the 3/32” bit once dry. This
will strengthen the hole.
