IBIS RJ.03 Project for Sale Asking € 4,700.00 (no VAT, TVA, MwSt) The information in this file is believed to be

correct at the time of writing. Even so, I

cannot guarantee that there will be no errors

or omissions. For this reason I highly

encourage you to inspect this project;

specifications subject to prior verification by

purchaser

I WANT TO FREE UP MY WORKSHOP

Substantially below replacement cost for just the material you’ll hit

the ground running with this almost complete airframe ‘kit’!

• Add foam for the wing, a VW-derived engine and instruments

and you’ll have most if not all bases covered.

• Taking over this RJ.03 IBIS project will reduce your build time by

at least 2 – 4 years.

• Price does not include shipment, crating, etc.

• No partial kit sale; the value of this project is in the

completeness of the airframe materials provided, the

templates & jig provided and the assembly work done so

far. It would be a shame to tear that apart.

• Transporting this project is your responsibility

Fuselage

The fuselage frames have been completed and have been assembled

to the longerons, see adjacent picture. The holes for mounting the

canard wing have been drilled. The bedding for the main gear ash

laminate have been completed, installed and shaped. Some of

the control cable pulleys have been installed as well. The fuselage

inside floor panel has been glued in. The outside bottom covering

of the fuselage has been prepared by transferring the fuselage

geometry to a plywood sheet.

All wood to complete the fuselage is provided.

Around build license #025 the fuselage design was changed to the

extent that the firewall was placed 2”/5cm further forward. The

overall length of the fuselage remained the same, so this design

change facilitated easier engine integration by creating more space

behind the firewall.

Please note that my project has build license #028, meaning that the

firewall is indeed moved forward compared to older license numbers.

The resulting easier engine integration is yours for the taking! ☺

Canopy

My project includes a free blown canopy bubble, which is coloured light

brownish.

To prevent scratches, the bubble is still wrapped in the foil it came in.

For added protection, I put the edges in foam tube insulation. My project

includes the wood needed to laminate the canopy frame.

Controls

The torque tube (steel 4130) that interconnects the front and rear

cockpit sticks was welded up beatifully by a professional welder.

The end bearings/busses have been fitted. After final fitting, you still

need to drill these and rivet them to the torque tube. The torque

tube has already been drilled to accept these rivets.

My project includes additional material to complete other (but not all)

parts of the control system:

• 7/8” diameter aluminum (2024-T3) control tubes that go into the

wing and actuate the flaperons.

• 5/8” diameter aluminum (2024-T3) control tubes for various other

push/pull rods.

• Aluminum bar (2024-T3), intended to machine the flaperon mixer

from.

• Aluminum rod (2024-T3), intended to machine various other parts

from.

• An assortment of pulleys and other sundries.

Canard wing

The canard wing is started, with the following parts done:

• Canard spar

• Drilling the holes for 4 mounting bolts + fitting to fuselage

• Canard rear (false) spar to mount the elevator to

• Ribs

• Leading edge (i.e. space in front of the spar) filled with foam

• Canard wing tips (see lower picture), which need to be filled with

foam, shaped and covered with glass fiber / epoxy.

The elevator spar & ribs are done and assembled. Some of the

hardware is mounted. Filling up the empty space in between the ribs

with foam and closing/covering the elevator still needs to be done.

Sheet metal parts

All parts that need to be fabricated from sheet metal were CNC-cut

(water cutting process) to 0.1 mm tolerance. What is left to do is to bend

and weld up some parts and to clean them up before

priming/painting. You’ll also get the CAD files that were the basis of the

CNC-cutting.

The upper picture on the left shows some of the parts that go into a bell

crank assembly.

The lower picture on the left shows the steel templates to verify the

canard. The lower template in that picture also contains an index

hole to accurately locate the axis around which the elevator is

rotated

Instruments, etc.

This is where you come in ☺ …!

The instrument panel is where most builders start to personalize their

pet project, so these are not included.

Engine / Propulsion

I didn’t get around arranging an engine for my IBIS project…!

So again, this is where you come in ☺ ! Most IBIS’s are equipped

with either a VW-derivative (Limbach, Great Plains, JPX, Sauer,

AeroVee, etc.) or a Jabiru 2200. You’ll need to get one yourself; also an

engine mount is not part of this project.

My website shows some parts that I intended to use for an engine

that I planned to assemble for my IBIS project, most notable an

electronic ignition system and a few carburetors. These are no longer

part of my IBIS project and are NOT included with this project sale.

Fasteners

High tensile steel bolts for mounting the main- and canard wing as well

as the main landing gear are provided. Other than hese, this

project contains no fasteners.

Winglets

The winglet base structure (spar, ribs, etc. as show on the left) has

been assembled. No other work was done on them yet.

Landing gear

The nose gear leg is not built, yet most of the required material is

available (4130 tubes, Grove wheel/tire/tube, etc.). The parts that

need to be welded up to the nose gear leg have been included in the

CNC cut sheet metal kit.

The main gear ash laminate is completed; the leading edge is rounded

into the prescribed profile. The trailing edge still needs the foam

formers (in which the hydraulic brake lines will be embedded).

Final fitting of the right wheel assembly is finished. The left gear leg

needs some minor trimming to complete the final fitting of the left

wheel assembly as well, which is something I could complete on

request.

The following material is included with the main gear, as can be seen on

the picture on the left:

• Wheels

• Tires + tubes

• Hydraulic disk brake

• Axes with mounting pad

• Mounting flanges/reinforcement

The cap crews and/or bolts shown on the left are temporary (non

aviation) ones, so as a precaution I’d rather not make them part of what I

pass on.

Braking cylinders and a braking fluid reservoir is included. The brake

lines / tubing are NOT provided.

Wood

Wood to finish the project is provided, including:

• Full length pre-sawn main wing spar cap laths

• Pre-sawn cap laths for the main wing spar center section

reinforcement

• Wood to build the canopy frame from

• Plywood to create the main wing ribs and spar webs

• Plywood to cover the fuselage, wing and canard

The spar caps have been stored out of harm’s way on the lower

storage bin as shown on the left.

The plywood has been stored in the movable sheet organizer you see

on the left picture. It’s big enough to store quite a few plywood

sheets up to 1.55x1.55m (5’x5’).

This plywood sheet organizer is not part of the sale but could be

acquired at an additional cost.

Jig / Templates

CNC cut steel template for the canard wing section. Included in the

sale.

CNC cut steel template for canard wing parts; steel CNC cut

alignment jig for mounting the elevator. Included in the sale.

Main wing templates included in the sale:

• One full section out of aluminum

• One full section (steel, CNC cut)

• One section segment (in front of main spar, steel, CNC cut)

• One section segment (behind the main spar, steel, CNC cut)

• One section segment (flaperon section, steel, CNC cut)

The wooden jig over which the ash main gear arch was laminated.

Included in the sale.

Paperwork, etc.

With my RJ.03 IBIS project, you acquire builder license #028. This

license is transferable, which is done by both of us writing a

transaction confirmation letter to Junqua Aircraft, who in turn will

respond by sending you a contract in your name. After signing and

returning this contract, you’ll be kept in the loop about IBIS-

developments (design changes or additions, etc.).

You’ll get two sets of construction plans: the drawings that originally

were issued with license #028 as well as a set of photo copies of a set

that was issued more recently. Based on recommendations from the

designer, I build from the most recent set, as these contain the

latest additions and modifications. The same goes for the 150 page

builder’s manual: you’ll get the original #028 edition as well as

photocopies of the most recent manual. It is this most recent

manual that I have kept up to date, with a change log and all.
