Fortis Airframes Titan Tricopter 15" front blades 10" tail blade

For this build I tried to fit together fun, fun and more fun! I decided on a Titan Tricopter frame for its incredible crash resistance. The arms fold and legs shoot off to absorb the energy from a crash. It reminds me of a Formula 1 car, the only thing left is the cage that protects the vital parts.

I'm more of a slow flyer and wanted longer flights, however I still wanted the responsiveness of a Tri. For this I decided to put on larger blades and lower KV motors on the front, and a normal size prop and motor on the back.

I just ordered a pixhawk to continue line of 3DR brains (PX4, APM). It fits nicely in the body of the frame with just some foam holding it in place.

2 x 15x5" CF blades

Thanks for the comment Artem, exactly what I was thinking, noticing the breakaway arms I thought having the arms be the batteries just made sense.

that idea has one critical (at least for me) flow,  the batteries will be permanently there, so fly once and than charge for an hour  :)

I am thinking having several sets to swap

in theory if I swapped the setup, and went with a Y4 layout, with the big prop on the back coaxial rotor I would increase pitch and elevator responsiveness correct?

coax setups are on average 30% less efficient than regular, just keep that in mind.

No server stripping so far. I'm trying out my Li-Ions tomorrow. I'll put up some pics.

How did the batteries go?
Comment by Daniel Lukonis on July 7, 2014 at 6:16pm

Well the batteries did ok for 2 minutes...then my droid crashed on me and sent some erratic commands to the copter via mavlink :(  The end result was an awesome loop then full power smash dive to the ground upside down. Good news!!! its all back together, well sort of. Its much lighter, I just left off the broken parts HA! I'm taking it up tomorrow morning for a test flight.

Where did you get the li-ion batts?
