hi George

at first i have to say this is our first time of fiber glassing
the first time we built it with mold side

but if you look at this photo the mold sides aren't visibele clearly and it is in dept of the wing
another point is the way of fixing when you have flat sides it is easier to fix it.

This is what the water tank is going to look like after the finish of construction.

I made a foam mold just to verify the size and the manner
in which the tank shall be attached inside the hull .

Amazing job! That's pretty scale too... actually it is like the real one, just in a smaller scale!

Thanks , Giacomo...

Having finished with the conversion of the tank bay, it is time to join the 3 pieces of the fuse: (see page 9 / post 207)
The main concern was the right alignment of the 3 pieces so as to get
a straight fuselage.
The pieces were placed again on the plans and for the alignment I used a level with laser beam.
The result was amazing .

Since everything straigt and while I was waiting for the glue to dry,
I deside to add a water ruder.
For this purpose a hole made at the end of the aft,
in which a carbon tube was glued at about 45 deg.
I'm thinking to use a pull-pull system for the ruder movement (last 2 photos).

Any suggestions are welcome.......

My good friend!!!
You did all this amazing job so far and you did all this artwork on the landing gear you spend
more than almost a year and now you destroyed all this wonderful job with those boxes.

WHY?

If you want email me the drawings for the engines and i can mold 2 fiberglass cowlings!!!
If you cant do that i can give you some ideas about how you can mold in the right way your cowlings.
It;s a pity to do all this job and destroy the image of the plane!!!!

The last time the idea of the ribs the one after the other was very good.
Obviously you didn't got the result you was waiting.
If you repeat the same but you cover all arround the wooden mold with stripes of balsa you could create a smoother surface.
Then after covering any gaps you create a nice smooth mold.
if you cover the mold with Vaseline (the easiest material to unmold the fiberglass cowling after its cured you could then do a nice smooth
rounded engine cowling.
You could even try to shape a piece of white foam and do the same.

I can give you some ideas...

Hi Dear Pappy

as you can see on the photoes we tryed alot and work on this part but we couldn't achieve what we want but it's not really unpleasant .
we got this idea from another model. maybe we couldn't found suitable materials since the black one is so heavy...

So here is my idea a little bit improved...

You can use the same template.

Look at the following photo then and try to understand....

imagine now that your template is covered with small pieces of balsa (planking technique).
This will create a smooth surface and you can then apply all your fiberglass tissue .
Before that you have to apply some sort of lubricating material so when the epoxy will be curred you could
take the molded part of.
As i understand you cant find special wax stuff on your local market but this is not a problem.
use a candle and melt it and then with a cloth apply a very thin layer on your mold.
Do the same as you did previously and the result is going to be much better
If you are carefull on how you going to unmold your cowling you can use it many times and experiment untill you get the best result!!

The second idea now.......

Oh Boy... you really know how to kill a plane...

You can also make a master in hardwood, put it into a refresh bottle (like coca-cola or pepsi) and put it into an oven... or just use a heat gun. Whatever, the formula is: hardwood master + plastics + heat. I used to make cabins in that way.

Cheers!

This white foam you can find it in every store that sells material for construction.
If you dont have very thick block find few thinner and glue them together.
Shape with a cutting knife to take the most of the big pieces of and then final shape with sand paper.!!
When you are done you can apply again some wax and then yse the same mold for the 2 cowlings!!!

at first we have to say that, it's our first plane experiment and we will use your ideas and experiments in the futuer for our other projects.
and second our goal of building a plane is to build a plane with 2 engines on the wing not exactly a Cl-215 becase we are mechanic students and we want to take a part in a competition and we haven't enough time to spent on the engine cowlings.

so we know it's not acceptable for CL-215 scale but we will be really glad to have your opinion about our plane because those are really helpful and informative.

OK I wasn't aware of that part... being so it's rigth (VERY rigth) to keep the stuff as simple as possible.
Being a student project, don't hesitate to PM me if you need any extra help appart of those we can give you in the forum.
Cheers and keep going...

I have to admit that as students you did a very nice job although that you chose a quite advanced model to
participate in the competition.
The amazing job that you did on the scale retracts is remarkable.
Since you did all this nice job, i supposed that you have high standards & that is why i objected on the cowlings. The objection was rather aesthetic then as the appropriate solution for aerodynamics. Besides in those rc modeling forums such as this one people pays attention to details and specialy on big planes such as a plane of 2,30 wingspan.
But if you ever would like to do the cowlings the planking solution on your ready template i believe that is appropriate.

Anyway good luck with your competition!!!

Hi , Nubiros...
Just keep the center-line of the tank close to the level of the carb spray-bar (or a little lower),
and also keep it as close as possible to the rear of the engine.
With a properly located tank the engine will run fine with muffler pressure.
