My twin star had four .32's and talk about unlimited vertical. It went so fast that the wings started to vibrate/flutter. I only made three flights with the .32's, then needed to do lots of cover repairs. It seemed that the speed and vibration just did a real number on the wing. It was also heavy, and I needed a good bit of lead in the tail to balance the model.

I then removed the .32's and installed OS Max .10's. It went from a screaming animal to a put-put. The take off now took a while, and though it flew ok, was not quick. I now have two AP .15's installed and awaiting two more to complete the re-engine work. It should fly just fine with the four .15's. Mine has dual aileron sevo's and mix in flaps with my Airtronics radio. Flaps help the rotation on takeoff as well as the landing too. The model got two pounds lighter with the .10's and with the standard tanks, would fly over ten minutes before I had to bring her in for landing.

The sound of four engines (four of anything !) is quite pleasing and a real ball to fly around. I've over 60 flights with the model so far and the only repairs have been to one landing gear vertical hard wood block coming off and causing the right gear to fold. That was a simple fix, and the hot glue that held the hard wood block did not have a good glue joint...it does now. I also installed dual main gear wheels, and a trailing arm nose gear assembly. That nose gear assembly really does help smooth out my landings, but the twin star is about as easy to land a model as I've ever flown.

I wonder if there will ever be a rekit of this model...

Soft landings always,
