The Super Sportster was designed for the sport flier The Sportster is fast, stable and aerobatic It has good looks, good performance and
stability at low speeds For the creative builders it can be detailed to resemble a war bird, Formula 1 racer or a CAP 21 type aerobatic ship Materials
are included for both trike gear and conventional gear (taildragger) to help you create your own Sportster
The parts are machine cut and sanded for accurate fit Some parts are razor cut in the 20 size for accuracy Should you notice a difference in
size between plans and parts, it is usually because paper plans change size with moisture Most of the parts are self aligning and do not require
building over the plans except where specified in the instructions
Different types of glues may be used such as epoxy, Cyanoacrylate or aliphatic (white) resin Be careful when using any kind of glue Make sure
you have enough ventilation CA glues (instant) are especially harmful if not used correctly
We suggest that you build on a flat surface to insure a straight wing and fuselage When you build over the plans, cover them with waxed paper
so the wood parts are not glued to the plans'
The following tools will be helpful when you build and X-Acto knife, razor plane, saw sanding block, flat building board T Pins hinge slotting
kit, drill and drill bits, tap and tap holder, covering iron and heat gun, Dremel tool and cutter tor wire and router bits, soldering iron, screw drivers, needle
nose pliers, files, clamps and a good square or right triangle
We recommend a plastic heat shrink covering such as Super Monokote to keep your Sportster light Follow the manufacturer's instructions
concerning the use of this covering material
Please read through this step by step instruction book before you start building so you will get an overall idea of the construction steps and avoid
mistakes Since these instructions do pertain to the 20, 40 and 60 size Sportsters, refer to the plan and parts list to help you identify the various parts
Any differences in the instructions for the various size models will be noted at the appropriate steps with a star (•*)
These instructions and plans were intended tor 2 cycle engine use However starting on page 26 of this booklet, you will find adaptation
instructions for the installation of 4-cycle engines

  • Page 28 This distance is "B". Refer to the drawings and the chart on the next page. We are measuring this distance so we can determine how far back to move the firewall so the engine will fit into the nose of the model. Figure 1 2-CYCLE ENGINE GREAT PLANES MOUNT...
  • Page 29 Figure 2 HAYES MOUNT Now let's figure out how far back to move the firewall from the normal 2-cycle position. We have already figured out for you the "A" distance of the Sportster 20 (3-5/16"), the Sportster 40 (3-3/4") and the Sportster 60 (4-1/8").
  • Page 30 Basically all we've done here is to measure how long your new mount and engine is, allow for some spinner back plate space and subtract the distance shown on the plan (A) from the distance you measured (B). The result gives you the distance you have to move the firewall back. (See Figure 3 and 4 also.) Let's do an example to show this.
  • Page 31 Step 36 Check for adequate width clearance for your engine. If your 4 cycle and mount is over 2" wide for the Sportster 20, 2-1/4" for the 40 and over 2-5/8" for the 60 size, you'll need to relieve the 3/8" or 1/2" balsa nose blocks and the 3/8"...
