this is my first scale attempt at C/L, so i choose a simple handsome design to learn the basics
The Chilton was the first scale model that iīve seen in person, back in 1986 when i started modelling and despite simplicity made a permanent mark
no reatractable LG, concealed engine and no rivets to worry about
i have ordered the real plane drawing plans and working direct over them, not drawing model plane, just working after the real thing
will be powered by a Saito 72 and use 3 line Bellcrank, as Brazilian rules forbid R/C uses
started last year, stopped for about 8 months and hopefylly will restart next month aiming to the nationals by the end of 2016
-
fuselage is almost complete now, have to work the cowl and find a full body pilot
-
I can see this is going to be awe some. H^^

Bravo Fred,
Beautiful fuselage construction, it's going to be a nice one. Love the Chilton.

Super choice of planes! Your construction is great, too.
-
thanks a lot for the kind words friends!
brazilian scale nats are getting closer and i took the project back!
some more progress with the worst part so far, the cowl
as i have not drawn any plan, and working directly over the real plans scaled down (similarities to a model is so close, that i saw no reason to redrawn anything)
after i figured out the cowl structure, everything went fine!
-
cowl is almost done, needs final sanding, scale details like hinges and glassing
started the tail feathers as well
-
Fred,
WOW! You said once we build much alike. That's exactly how I'll be building the cowling on the FIREBOSS.
Outstanding, now I have photos thanks to the Jedi Master. BW@
Isn't the Forum great!!
You're work is clean and precise.

Beautiful carving skills shown on that cowling, Fred!

thanks a lot Cris, indeed this is the only part that needed carving and now i have to work on the outer wing panels and stab, other thatn that, itīs finishing & detailing

Jedi master looks like a "Marcus" thing, thta guy lol
so glad this came out nicely, as i havenīt drawn anything i was finding if itīs going right along the process
and yes, you have a gifted talent Charles!
more to come today
-
fin & rudder done! tomorrow will work on the stab
my main concern with this bird is the saito 72 working properly on the 3 line system, wich is all new territory to me
next will work on that!

If you have an old model that can use the .72 drop in a 3-line bellcrank and give it a try. that will give you experience with the 3-line system on a hack airplane before you drop it into the good model.
Then you can use those same lines on the good model later on. You can also break in and test the motor
Find a model with similar wingspan and weight and convert it to CL

Hello Fred
sounds the best method, unfortunately, i donīt have time for it, the competition will be held on 27 november! so i have to trust on my building and go ahead with this plane
fuselage is almost done
needs to make engine mount and stab
then, go back to wings
-
Yeah that is close, you don't have time
When ever I test fly a model I do 2 or 3 taxi laps checking how the model tracks around the circle. If the model tracks ok at slow speed then I go faster but not so fast that it can fly. Then get the speed up so the tail gets flying so you can feel out how the model is responding and rolls on the mains.
Once you get enough airspeed to get airborne take it slowly, if it flies ok take it all the way and climb out. If the model is too pitch sensitive you will know it and don't take it up.
I saw a model do a test flight, they went to full power rolled a 1/4 lap got airbone, climbed out too steep, stalled and then crash 1/2 lap later.
Might be a conservative test flight but I find out early if there any problems

sounds good Fred, nice tips indeed!will do exactly as you described! thanks!!

bit more work, landing gear done, tail attached, now itīs time to wok on the outer wing panels and install the elctric engine
unfortunately i missed brazilian nationals, but will finish for 2017 hopefully!
-
tail ready
-
PITA landing gear lol
