Caravan 1/2 A

Very cool. I love free flight.

Jose Excellent !, I will be visiting the post sharing your progress! ... A hug, Mauricio .-

Nice! I like those pylon style models too. Are you going free flight or radio assist?

Thanks for your comments friends.  

Yes, I also love very much "free flight" over all categories.  

I think is a pure art. Trimming airplane to circling thermals.  

But today at XXI Century better radio-assisted    because here there are many trees roads and railway close.  

But normally I don´t touch transmiter during the flight but is to bring him or avoid an accident.

I just enjoy seeing flies free lying on the floor.  



We have several vintage motorgliders.

Two super high pylon wing "Timer´s Nightmares" of Frank Ehling

The "Frisco Kid" of John Tatone very similar to this Caravan.

And "Engendrus" a personal design home-made with recycled free fligh gliders parts and powered    Tee dee .020.

I want to buid the Caravan strongest than Frisco and Nightmare, they are very light and low weight for quite weather, and I want the Caravan for fligh in all conditions.  

If .049 it is not enaugh  power to clim higher and fast, I could mount a big engne OK .074 with auxiliar tank into the fuse and Tatone timer to cut fuel to practice vertical takeoff "V-tol".  



Now assembling the fuselage, note the top and bottom veneer with cross grain to improve the torsional strength and two steel wires 1/32" diameter transmission for rudder and elevator.

The fuselage and the rudder will be covered with very bright colors



I have made a modification to the plan and I build the wingtips trapezoidally



I used wooden harder in the central wing panels as they work to greater bending stresses.

It is very important to make a good joint wing panels, I used dihedral reinforcement ply sheets on all spars.

Gluing dihedral joints



Wing finished ready to cover



Horizontal stabilizer is very easy (no dihedral joints).

I use clear oracover at centre wing panel because oracover is strong, and blue clear oralight at tips wing panels.



Wing weight 125 g (4,41 oz) span 1130 mm (44,5 ") coord 190 mm (7,5 ")

Beautiful work! It looks super. I bet it flies really well.

dihedral can be a trip to glue right. Looks good. I like the colors.

Thank you for your comments. I'm glad you like it, someone knows the name of the designer ???


I choose vivid, bright and colorful and above all visible colors height, flourescent is the most visible.



High visibility can make the difference between seeing or not seeing it.  



Although I have built a larger elevator to desthermalizer tilting 45 degrees with servo.

Flying surfaces covered



Fixing system of the horizontal stabilizer with rubber bands



Hole between stab and elevator to put rubber bands

I mount this Babe bee .049, it has a shim at botom cylinder, I think to remember it was to modify timming to use larger props ?

Anyone can confirm it to me?





At first, I mount this plastic yellow 6x3 " ... if don´t pull enough ... I can change by grey 7x3,5" to increase thrust.  

If it is not plenty power ...  I will mount this Tee dee .049

Finished



Ready to fly

I'm not sure how I feel about the checkerboard fuselage... Then again it is YOUR plane. In any case that is a good looking plane.



Nicely done!

Phil

Thank you Phil, may 2016 is the Chess month



Check Mate ! Reds win !



This afternoon I flew it for the first time, I could not wait any longer ...  

Tonight upload Youtube video maiden flight.    

Looks great! I am looking forward to watching the video.

Here´s the Caravan stressfull maiden flight video.    



I´m still tired ..

It does teach us a lesson.  Don't assume that you remembered everything.    Always do a pre-flight check of your controls.
