Twin Rhino (Siamese Rhino) Airborne

OK, so I finally got serious about building the Twin Rhino (which I now decided to call the Siamese Rhino). Of course, this is just the start. I previously tried to build the centre plane using foam core and hot wire but the wing is to complicated. So, built up balsa is the way to go. I gave the centre wing (the wing connecting the two fuselages) the same span as the other wings.

My concerns are that I have two aircraft together, with one centre plane and I have lost 25% of my lift area. My reaction has been to increase the overall cord of the centre span by about 10%. This won’t totally compensate for the extra wing loading but I have added a decent centre span flap to reduce the landing speed. (Of course… lousy pilot skills have not been factored)

Everything in both aircraft that are to be married match, so I believe this odd aircraft will fly…. And fly well. We’ll see.

After writing the above I took the aircraft to my club for some ground testing. During a high speed taxi run the Twin Rhino rotated and looked quite comfortable in the air. I backed off and she settle back down on the ground,she was comfortable it's just that I wasn't, the wind was a bit fickled so now we just wait for the right day.

9/2/18   The Twin flew today. It was perfect, right from the takeoff roll. It took to the air like an eagle and it felt comfortable right from the beginning. This aircraft gets full marks... :)

If you are wondering about the he Autogyro in the following articles... All I can say is that it is a rotary aircraft and as such its hard work... it will happen but I need to do a lot more work. At the end of the day I ill have developed an aircraft that can be configured as a monoplane (parasol, high wing or low wing), biplane or twin... and tuff as nails.
