After 40 years...finishing the Electric Canberra MK62


Hello
in the beginig of 2010 i received a plan of this great plane. The designer is Tito Johnston who draw it in the earlies 1970...
not EDF, not lipos in that time...
when he gave me the plans i put an 70mmEDF over the duct ant it fits perfect...so i decided to start the model at the original plans scale: 1/10.

Its made with EPP in 3mm and 5mm. Fiberglassed witn 20/48 and 70 grs/m.
Inside with carbon fiber, some balsa, and wood in 3mm.
1,95 aprox x1,95 . Weight (without painting 3700grs) ready to fly.
2x70mm EDF from HK with 2 45amps ESCs, turnigy regulator, 5x 3kg servos, 1x1,6kgs servo for bomb bay...1 4S LIPO 4500mah.

some preliminaries...
canberra prelimina_WindowsMedia - LAN.wmv (3 min 8 sec)



the second flight...with 300grs in the nose!...i must move everything forward!
2do Vuelo Canberra MK62 RC (8 min 16 sec)


Thanks Terry Mitchel for inspired me with his great skills with depron and his Canberra too.
Thanks Tito Johnston, a great person! a great designer...
A lot of people help me to carry on this project. Thanks everyone!

Thanks

Many congratulations Juanfe. It flies very well and a good scale speed.The power package looks well suited for the airframe. I love your little band of helpers , weather, and great flying site.I will toast your great achievement this evening with a glass of Scottish building fluid. WELL DONE.
Best of regards,
Terry (The old man from Bristol)
P.S. I have just been told that I am going to be a Great Grandfather.

Hey Pontius!
Thanks for your words!
the brave pilot from Bristol...(the old man?...jaja! why? because you are going to be grand father? no! now you have to teach your grandsons to build and fly rc models!...not old!

Terry i have 2 questions:
1) move everything forward, its tail heavy and i have to put 300grs of blast in the nose...the lipo is far forward, only can move 4cms forward both fans, everything is forward...the real plane has all the way concentrated rear the cockpit...

2) the eflux air at high speeds make some fluter in the elevators...dont you have these problems in yours?
IŽll try to move the fans and speeds...and to make a new push roads with fiber carbon tube for elevators to minimize mechanical losses in the joint.


Hello domll, thanks!
The EDFs combos ar

Hi Juanfe.
My Grandson is 24 Years old and I gave up trying to interest him in moddelling many years ago. It`s my 22 Year old Granddaughter who is expecting my first Great grandchild, I will have to try again male or female.
I have lead in the nose as well Juanfe, don`t worry about it.
Never had flutter but then my aircraft are very slow.
Terry.

Thanks!
a friend of mine, Alberto, painted the Canberra
I did the deco. Like the Bravo 105.


I flew the B105, last weekwnd in a big airshow (120.000 people) during the end of the day, while the suns goes and the flag where going down.
The airshow was for the 100 years of Argentinians Air Forces, and it was in the Canberra's airfield. Here in Parana.

A lot of people, and old pilots, remeber a lot of good things while the B105 crossed the skies. A lot of people enjoy the model
I hope you too.

the 70mm EDfs fits perfectly in the original plan...
only to reshape the outlet duct, and some considerations with the EDFs instalation, because in the original plan, the main retratc sistem (very complex, 40 years ago...) sites in the EDfs place...i had to relocate the retracts.Inner position.
More pics of the finn and rudder build.
Thanks

Buildings what I enjoy.
What a terrific job building then flying this graceful plane. I have to say my Canberra has waited even longer to officially be test flown as I built it near on 15 years ago and its such a thing so close to my heart I can not just in case something goes wrong.

Well done to you for a great job.

Hello
thanks Rich and Shane!
more pics...
finishing the rudder, with a compensator..
the weight of the whole empenage is about 131 grs...(sanding missing)
the idea was build as the original canberra was built...
the tail, the nose, the center and the wings...after that join the pieces...
I worked over a piece of glass (during the project), and i have no more room to keep the project in one place...
The rear part of the fuselage...
and i did some holes to loss some weight (no so much...), but it kept me ocupied a lot...

then i worked on the nose, like i did the tail.
Thinking to have enough space for the pilot and some interior cockpit details...
i did some tests with both edfs...and the brakein...

See you later!
