Foamaroo First Flights

I was able to fly the Foamaroo for the first time today despite some strong winds and threatening rain. All I can say is, I'M IMPRESSED!!!

The airframe came out to 2 lbs 11 oz with everything, including the 2200 MAh battery, installed. I had help handlaunching for the first flight (thanks Leadfeather!) and it only took a couple of clicks of trim to get it to fly level.

Concerning the winglets, I used Coroplast for three reasons:

1. It's light.
2. It's inexpensive.
3. You can easily make and replace your own if you break one.

I did some sliding landings on hard packed dirt today and there was no damage to the winglets.

The climb rate is very good at full power and it will cruise comfortably at 1/2 throttle. I did several stalls as well as loops and rolls and am happy to report that the plane is really fun to fly. We were all surprised by the roll rate. I wanted to set up exponential on my radio so I brought it around and set up on approach. I was able to do a zero roll out landing on the first attempt and the Foamaroo set down on the grass.

For the second flight I wanted to hand launch it myself so I grabbed it just forward of the wing, throttled up and threw it like a baseball. I was happily surprised that I didn't need to give ANY flight control as it flew up and away, wings level. I did a series of launches and landings and was able to get very comfortable with it. The winglets don't cause any problems on landing with some speed and the fuselage held up well with no damage.

My second series of flights was over 20 minutes on a 2200 MAh battery and I'm sure the battery had plenty more in it but I broke the prop when I did a hard landing to see how the airframe would handle it.

The video quality suffered some due to the cloudy skies we had today. We'll shoot more as soon as we get a flyable day with the sun shining.

A big thanks for Leadfeather for shooting and editing the video.

Here are some pictures of the first flight.
