Well it's been a long time coming, but I finally got to fly the 3D Foamyu Advantage bipe. The conditions were not real good, but it was fun. First off as I expected I need more power. A Hacker A20-20L is in this planes future. Second I don't care for landing without landing gear and since I have a set and will have the power to handle the extra little bit of weight with the Hacker it's getting landing gear. Third the prop saver O-ring mount allows the prop to move around a bit when you really pull on the sticks so it's outta here as well.

Conditions: cloudy, 5-8 knots first flight, 10-15 knot gusty winds second flight and a lonely few rain drops.

Alright on to the flight report. WOOHOO. These planes are suppose to fly better in wind than flat wings and the Advantage lived up to this. I had no tracking, pitching issues at higher speeds and it got tossed around a lot less than my Eflite Ultimate and Skeeter 30, yet it's the same weight. Control authority is great at all speeds. The plane flew backwards level into the wind at low throttle and remained very stable. Harrier landings were stable and the plane only gently dropped a wing when it stopped forward flight just an inch or two off the runway. I was able to get a hover in during the first flight when the wind calmed down a bit. This plane hovers much easier than any plane I have ever flown it dang near just hangs there with a bit of aileron. The current motor requires full throttle to hover so I didn't bring it down below 5'. Knife edge requires just a little rudder and a touch of up elevator to compensate for the typical biplane pitch coupling. High alpha knife edge could be held stationary with ease in the wind. Rolls are nearly 1 per second and very axial with no differential throw. Flat spins are too easy, just bury the sticks in the corners and around it goes, increase throttle and it climbs, decrease throttle and is decends(I love planes that do this well). Recovery from flat spins simply requires releasing the sticks. Harriers, well considering the wind it did very well. Upright there is a bit of wing rock, inverted it was rock steady. Loops tracked very well. This plane actually glides which is something the flat wing planes lack IMO.

To some it up, so far I say this plane rocks. It's very predictable, stable, handled the wind nicely and most importantly it was fun to fly.

The only things I'd change are to have a bit more aileron. I like insanely fast rolls, currently the rolls can still be easily kept up with. Fast enough is when I can't time the elevator correctly and the wings are almost blurry, LOL. However, there is more than enough.

I found that before the first turn of the first flight I had flipped to high rates which are set to all I can get with Dubro micro 3D arms, probably 70 degrees for aileron and elevator. Keep in mind though that I like my sticks really sensative.
