Twinstar maiden goes perfectly!


The 4S, I learned, is a little tall for the hatch, so a piece of Velcro as tape holds it on. As an experienced builder ya think I would have test fit the battery before I left the shop...


Early afternoon, cold breeze from the south, sun
low on winter horizon standing unfetteringly bright just a few degrees above the southwest tree line.

The fall grass is thick and clumpy, but there are parts where its almost mud. I carry the Twinstar over to one of these barrens and face her south, down field. Check control surfaces, check flaps, check full power run up. Look, listen, feel. First flight. Be a good girl.

It's time. Full throttle, and she fights her way down the runway, such as it is, and as she clears the grasping grass and gains speed, the powerful torque of twin props rolls her to starboard. I easily correct and take her into a right climbing turn to clear the western tree line, avoiding the sun line. She gains altitude too easily. Nose down trim, a bit of left aileron trim, a tweak here and there, and in a few passes she is trimmed out despite a choppy wind aloft.

The power setup is spot on. The 4S nestled in nicely and she is balanced now. She won't go vertical, but she is aerobatic. In fact, my low aileron settings are too high for even high settings, and I had the low rate tuned to about 35%!

I try to slow her for a landing approach, a long one, but even with 50% flaps she is fast on the final. I need the higher aileron throws at approach speeds with the flaperons down. She descends nicely, predictably, but fast. Several landings and approaches, its just the way she is. And she puts her nose down when those back wheels touch the thick cabbage, and she buries her nose wheel and abruptly stops, stuck where she came to rest. It's a walk in taxi almost everytime.

A couple of times I manage to find a muddier less grassy spot and she rolls out. But her props are green with grass she had cut and thrown into her wings, and the green slaughter coats her props, belly and nacelles.

I fly two or three packs, at 10 min a piece I have already forgotten. She was quite an easy flier.

I had brought the 30cc gasser, but even after this fine flight set, I really am not in the mood, so we pack up and head home.

Flying is better with friends, but no one is home, so I fly alone, and thus my stay is brief.

It was a great maiden, good design, good build, good engineering.


Nose wheel is bent back by the grass.
