Harbor Freight Bi-plane Free Flight

My dad sent me this Bi-plane from Harbor Freight. It weighs 2.4 oz. with motor and NiMh battery. Too windy for a maiden flight.

Anybody have one? Anybody convert one to r/c?

Hi B717,

Sure, I have one and so do lots of others. An Acro-Bipe by any other name!! Mine will soon be R/C. With appropriate trimming, they fly well free flight. There are several threads about conversion to R/C but, sorry I haven't got them bookmarked. For R/C, the stock motor is an amp hog. People have used IPS motors, actuators and servos in the conversion with great success. If you want to convert yours to R/C, don't lose it OOS freeflight first. It is a fun little airplane as a freeflight (my experience thus far).

Hi Bick,

I should have searched before posting, as I found numerous threads on this little airplane. I'm going to keep it as a free flight. But the seed has been planted, so to speak, and now I'm thinking this would be a fun indoor r/c airplane.

This is the third Harbor Freight free flight plane I've received from my dad over the years. The first two consisted of a high-wing tail dragger (C-185 type) and a low wing sleek Glasair type. The Cessna was destroyed in a tree rescue event. The low winger was destroyed when I left it in the back seat of my wife's car. The latter seemed underpowered.

With two wings, I imagine this bipe should be livelier. And with today's sub-micro electronics, I'm starting to imagine an r/c conversion. I love r/c electrics!

Try one FF before you start cutting it up. They do pretty well.

I tried it FF and it's now MIA.

The winds were calm (honest) at launch. The bi-plane slowly climbed while performing left-hand circles. Then the morning breeze slowly developed into a soft ~3 mph; so the plane's wind circles slowly drifted away from my large open field toward a neighborhood. I wasn't worried until the plane was half way to the houses and getting pretty high. The motor still ran strong too. At times the wind might have reached 5 mph max; but who knows what they were aloft, if much. A couple of times Murphy reared his head, causing the plane to roll out staight, of course always on downwind.

The bi-plane circled its way several blocks into the housing area. At this point, I couldn't always see it, and was unable to pin point it descent path; plus I had a flight to catch and couldn't devote much time to searching.

Fun while it lasted. I can't believe how long that motor kept running on one charge. Considering the very light winds, this plane covered a lot of ground.
