TRIM AND BUILD HINTS.
Following a fair bit of flying at relative high power I have some extra hints for trimming and flying this model.
BASIC POINTS
1. Leave the wing as shown on the plan and use nose ballast instead to balance where shown.
2.Add wing position keepers at TE of wing.
3. Rear hook as shown does work but could benefit from being a little further from fuselage. Also a short sleeve(straw heat shrink) could help avoid bunching at the rear.
4. Keep motor knot on rear hook to minimise motor bunching towards rear and spoiling glide.
5. The model is designed to fly right - right. It should be launched at around 40-60 deg nose up with the wings level or with a slight right bank. left bank at launch kills the climb.
6. I have found that the climb is better if the fin is extended approx 1mm higher and 1mm along the TE. The LE position and angle stay the same. This has stopped the model going flat on the climb during the first spiral turn.
7. Adjust for initial glide with nose ballast rather than warping in up elevator.
8. Optimise glide again with slight changes to nose weight when climb is under control and around 2 climbing spiral turns to the right.
9. A 230mm long loop of 1/8 (old black FAI) worked well and gave a slightly better glide. Tan SS may work better at this length.
10. Use a minimum amount of right rudder offset to help model on climb. this should then provide enough glide turn. If you need a tighter glide turn add wing tip weight on the inside wing instead of adding more right rudder.
11.If it hangs on the prop at the top of the climb - check for bunching at the rear hook and if necessary twist in a slight bit more right side thrust, to the Sig nylon front bearing.
12. Expect about a 10 sec motor run approx giving around 80' climb.
