My FT Tiny Trainer Build
I have been wanting to build a bixler style plane for a while for the use of teaching others and having a bit of fpv fun myself. After looking around on rc groups I couldn't find anything. So I looked on flight test and found that Stone blue airlines had created someting similar to what I had in mind. Here is a link http://www.stoneblueairlines.com/hangar/airplanes/vas-aircraft/vas-spark-2-0-36-wing/vas-spark-airplane.html
After the FT Tiny Trainer was released it seemed like a good base frame to develop. The size was also favourable as it allowed it to have good glider characteris but the abbility that when crahed it is cheap and esys to repair.
Here is what I did.
Building The Fuselage
This covers the steps how to create the fuselage:
I started off by making the body and tail using the plans from the FT tiny trainer. Once glued together I created the nose. The nose is the glider nose from the trainer and it fitted well allowing me to put the battery right at the front. As the nose is detachable it also allows it to be replaced in the evnt of a crash.
To evelvate the motor I created a cockpit like on the bixler. It is the same hight and width as the glider nose so I could just glue the two together.
I then made ther power pod. It fitted sungly inside the new cockpit. Like the bixler I decided to add some angle on the motor to give it similar flight characteriscs. I used to bbq sqers at an angle to hold the power pod. The motor in using is a 250 size quadcopter motor that I had spare. A larger motor could be used but isn't nessaceray as this provided plenty of power and the ability to have a vaired flight envolope.
Next I made the wing. I decide to go with the speed wing as it had good size ailerons and I have been flying for a while and so the poly dihedral was not needed but if you are just starting out the poly diherdal wing will work just as well. The speed wing also had good characteristic when performing so basic manouvers like rolls, loops and inverted flight.
I then fitted all the electronics. I'm using a
2200kv mini quad motor with a 5 inch propeller
3 hexatronic 9 gram servos
1000mah 2cell and a 1000mah 3 cell
1 1/2 sheets of foamboard
1mm piano wire
Here is the Finished ProductHere is the finished product. I added a lick off paint to give it a bit of character and then maidened it the evening I built it. It has an all up weight of 457g. It has the ability to carry fpv gear as the motor provides plenty of thrust and i will attemp to fit gopro and will update you as I fly, crash and have fun.
I decided to go the next step by adding a camera. After acidentally destroying my gopro i used my sj4000
I headed out to a field that I usually fly at and gave it a test. I crashed into a tree after the linkage stopper poped out.
I was a bit sceptical as I wasn't sure how well it would work but I was completely wrong. It handled like a dream. The high wing gives it a floaty feel and can easily be flown at half throttle. I was getting flight times of about 9-10 minutes on the 1000mah 3cell. I will also do a test with a camera mounted to see what the onboard footage is like. Currently it only has ailerons and elevator but rudder and flaps could also be added. Hope you attemps this build yourself.
