RE: Lanier Mariner 40 MKII ARF 62"
Mariner - Maiden flight report.
Engine: Saito 65 with 1x 6 prop.
The engine has plenty of power, flew at 1/2 throttle. Plane flew great on several flights except the last one. Lake was getting choppy. Mariner took off fine but started to porpoise, flying unstable as if it was tail heavy then flew well then tail heavy. Successfully landed and some water inside. The plane was balanced level, so a shift in weight would make a big difference. We think the water moving around shifting the CD. That was the last flight of the day.
I suspect the water came it through the wings leading edge; I used wing saddle foam around the wing except there. Also plan to use wire in the control rods, too much flex is also suspect.
Overall good flying plane. I hope my fixes remedy the
