I just finished my Flubber. It has a Hacker B20 18L w/4:1, Hacker 18-3P, Thunder Power 2100 3s1p, and Electron 6 receiver. I left the cowl, canopy, and belly pan off for the first flight.

I set the Hitec servos up with the control rods on the second hole out. I initially set the low rate throws to 50% with about 30% expo. 50% throw came out to about 15 degrees. For the first few flights I'm using a 10 x 4.7.

There was a strong wind (about 10 miles per hour).

I was taking off from grass. I found that with just a little throttle the plane wanted to nose over. A lot of throttle got it rolling just fine. I pulled up a little too hard into a steep climb. It didn't seem to matter though, the plane just kept climbing.

The ailerons were very touchy. Despite that, I managed to land so slow I could have walked over and picked the plane out of the sky.

For the second flight, I went to 40% throw with 50% expo. This made the ailerons very comfortable. It was difficult to tell how well the plane tracks as the wind is very turbulent above the trees where I fly. Nonetheless it was very responsive and easy to control. When the wind would blow it over (usually in a turn) I could bring it right back.

This is my first real electric and I have to say it was a great pleasure not having to re-fuel or clean the plane. Best of all, I could not even hear the plane in flight.

I read one review of the plane before I bought it. The reviewer complained that the horizontal stabilizer was a little flimsy and needed reinforcement. He added carbon fiber rod supports underneath. I used a little epoxy at the root when I glued it in and mine seems fine.

It would be great to hear any of your setup or modifications tips.

Thanks,
