Seagull’s Spacewalker II will appeal to a wide variety of modelers who are looking for a great Sunday knock-around airplane that won’t leave them strapped for cash. Built from balsa and ply and covered in a great-looking UltraCote® trim scheme, the Spacewalker II is anything but “cheap.” Matched with any .40-size sport engine it will provide plenty of sport aerobatic fun.
|Approximate Assembly Time:||7–10 Hours|
|Flying Weight:||6-7 lb (2.7-3.2 kg)|
|Wingspan:||61 in (154.9 cm)|
Choose the lightest weight, highest power engine you can find, within the engine recommendations. The Evolution 46NT is a very good choice for this plane for great performance with low weight.
You can use any 4-channel radio system.
Standard servos are more than adequate for the plane. But keep in mind that the better servos you use, the better the plane will fly.
Using a computer radio, you can mix elevator and aileron to rudder to make knife-edge track straight. Keep in mind the lower the weight of the plane; the better it will fly, so keep additional weight to a minimum.
The brace may be loose fitting in the wing and this is intentional. This is to prevent the epoxy from being scraped off the joiner and not getting adhered to the wing. Use enough epoxy to ensure a good bond.
To prevent the dowels from “burning” themselves from vibration etc, lightly coat the dowel with thin CA, let the CA dry, and sand smooth with 600 grit sandpaper or similar. You will need to only use enough CA to cover the surface of the dowel. You do not want to increase the diameter of the dowel with the CA. Let it dry completely before sanding the dowel smooth.
Also at this time locate the wing screw reinforcements shown on the pictures on page 5. Remove the covering on the wing where the blocks will go as pictured, by carefully cutting the covering with a sharp x-acto knife, using extreme caution to not to press to hard with the knife and cutting the wood. If it is cut too deep, it will fail. Then sand one side of each block to remove the paint to get a better bond. Then adhere the blocks to the wing using epoxy.
Also at this time clean the inside of the tank to remove any debris. If any water is used to clean the tank, be sure to let the tank dry completely before assembling the tank.
The distance listed of 5 5/8” is a misprint, the distance should be 4 1/8” to 4 ¼”.
Place a drop of loctite on each screw. The washers included are not split washers, but rather flat washers.
This is a repeat of step 6 and can be omitted.
