Canadair CL215 - Amphibious Fire Fighter

A few months ago I watched on Discovery Channel a documentary with this plane, a powerful fire fighter.

After that i traveled to a farm where there is a beautiful lake, so I decided to make it before the next trip.

The model was easy to made cutting EPS with hot wire. The most of the job was covering it with 3M#77 Spray and color packing tape.

The first picture below is CL415, his big brother. Actually is the same size, but with turboprop engines they added winglets and vertical fins on stabilizer to increase stability.

The other is my CL215.

More pictures in the lake.

Takeoff from the water is as easy as from the ground with wheels.

I think flat hull is perfect for this kind of model.

Before building it I made several test with hulls on the swimming pool, the better results are with flat hull with a step a few inches after the CG and flat depron skids as wing tip floaters.

The watter rudder was a piece of aliminum soft drink can, but it fall into the lake, the hot melt glue that keeps in place worked very well.

It is strange, but takeoffs from the water with this model are safer then with wheels.

To abort a take off from the water 3 meters are enough.

When I turn off motors a few meters are enough to slow down, sit the water rudder on water and make a turn, so taking off so close to te margin is not a big deal.

On the ground with wheels it can take 30 meters (100 feet) to stop, so, if it can't get airborn is a hard decision to crash a little slow on the sidewalk (my flight site is a parking lot) or to try the takeoff.

Thanks,

Takeoff from water is as easy as from the ground with wheels.

This is really a good flyer, stable like flying on rails but can do very sharp turns without stalling or loosing altitude, an excelent park-flyer.

I am on countdown to next weekend on the farm (June 18) to fly it from lake again :P

Thanks for the comments.

Me and my friends traveled to fly again in the farm last week.

This is the result, finally a good video to see how it flies:

Unfortunatelly playing U-turns with an aircraft model is not a good idea.

After many flights it got airborne while playing, but ailerons and rudder are both fully deflected, so it flew 2 meters and dives upside-down on the water.

Then it turns into a submarine, but without damages.

Just an isopropilic alcohol bath on the electronics and it is ready to fly again.

By the way, always have isopropilic alcohol when planning to fly over or from the water.
