This project started late last year when I picked up a OS LA-15 engine from GauravAg on this forum. Stuck with Guppy, I desperately wanted to start something else around the engine and picked up this plane.

The Plane was designed by Pierpaolo Pastono whom I could not reach to get permission for posting his design on the forum. I sent him lot of mails, but no reply. So I am posting his original plan, along with the modification I did on the CAD file for laying out the side panel of the fuse to receive the wing.  I would be sharing the Corel Draw files which are good for cutting part on CNC Milling machine/ CNC Laser machine. The Files have every thing neatly laid out, except the the two formers where front Wing Dowel and Bolt at the trailing edge goes. I am yet to hand cut them according to size.

I  am sharing the files purely for the benefit of the community and take no responsibility of any errata and ensuing loss of material at your end.

<I could not attach the Zip/DWG/CRD files due to forum's file format / size restriction. I shall post the link after I upload the files on some file share site>
 
Specs:

Wing span  : 48"
Lenth        : 35"'
Engine       : 15 size
AUW         :  1.5KG
Channels    : 4, 4 Servos
Material:
         3mm Balsa for Ribs
         3mm Ply for Formers,Firewall, Root Rib, Fuse panel
         Spruce/longeron of various thickness as specified in the plan.
         Balsa Leading Edge and Trailing edge as per plan

Before I put the Plan files, here are how the Laser cut parts came out. It was my first tryst with AutoCad and I got great help from 'Rajib' on this forum who is silent for the while.
Few ribs got a bit charred, may be due to extra overlapping lines or the CNC guy mistake.

 

superb

nice build

good luck for ur build..

Some fresh air

Please send me the files to be made public, and I will attach them to your first post.

Thanks Gusty Sir and Krish. Hope to finish the build log soon with the plane itself.
Satz, the planes in the above pics are not the one I have already built but would look like if things go fine.

Folks, I have sent my CAD/Corel Draw files to Anwar to be attached to the thread. Unfortunately my Corel Draw copy I had has expired and I could not see the final CNC layout files. Please dont jump to get the parts cut before I verify once again.

Would post more pics later today.

I am nervous today as my Aeromodeling Guru from my childhood days is in the city for a short  trip from US  and I am taking him Yellahanka field to show flying. Hope there is a good show there...

isn't the trim more like a Candy? you have homed onto it after a lot of search i guess. just a passing thought

Plans added to bottom of first post.

Great Going Ujjwal  


PS : If you could be kind enough to offer a Complete CNC laser pre cut balsa kit for a 0.1 & 0.05 size say less than 36" WS for sale would be more than glad to buy few of them. No CNC laser cut facility in  Shillong       .

Nice one Ujjwaana.

God bless you.

Oh this needs too much patience. Was this the one you showed us the other day?

@Gusty sir, love at first sight. The trim scheme looked so appealing  to me and the color orange is good for orientation.
@Thanks Anwar sir for taking the pain of putting the files.
@Foamy: Yes indeed
@Sumdaram and Rao Sir,
@Akshay Sir. My progress in this hobby is so much due to your relentless dedication  Yash's flying passion. I so, so ,so much owe all this to you.

   I would love to provide kit service to other flyer. I even tried to collaborate with some LHS. The issue of copyright and unavailability of Balsa/Lite is the one of the basic problem. The other logistics problem is getting the particular CNC technician come on Saturday to get my delicate job done in time. But I can still try help other in my capacity.

Coming back to the build itself. I started the construction with the Fuse, and perticulaly with the bulkhead portion.


1. Paste the two Bulkheads former F2 ( cut out in grain perpendicular to each other) with fevicol SH/slow healing Epoxy clamp them together and  leave it overnight. make sure that the holes for engine mount bars and Longerons should align properly.

2. Paste the 5/16 Sq Spruce to across the Former f2 to supper the Engine mount bars. (Bulkhead1.JPG) This should be flush placed at the holes for the engine mount bars. Put another spruce on the other side of the former, but this one on the other end of the hole.  

3. Paste the  5/16 Sq Spruce Engine mount bars through hole (Bulkhead2.JPG). Use a set square (better carpenter's metal one which has a wide handle to rest on) to ensure both the bars are perpendicular to the former on both the axis (length and width of the former). The bar should be a 0-0 angle to the former. Use washers to set the thrust angle shift later.

4. Once you have the bars pasted, now paste the F15 to further support the bars (Bulkhead3.JPG).

Good start Ujjwaana.  The CNC cutting is superb, I am subscribing to this thread.

It's all Love, you know.

I always pray to God, that we may have more people like you in this world and this hobby.


More to come, I presume.


Keep it up Buddy

All the Best

<You are being so modest Akshay!!>

Now we join the Longerons which run from the Tail to the firewall and wing aft to the firewall.

We would need 4 nos of 6x6 SQ spurce sticks.

1. Start with the two Tail-to-Firewall longerons which would attach to the top 'flat' end of the firewall former F02 (Longeron1.JPG)
2. Use the set square to ensure that the Firewall is perpendicular to the longeron (Longeron2.JPG)
3. Attach the loser longeron which run from Wing aft to the firewall. Ensure it is parallel to the previous longeron by fixing the vertical support beams and the end (Longeron3.JPG)

Now put together the lower Aft Fuse Stringer.


1. We would consume the Formers F11,F12,F13 and F14 as in the Plan. We would also need length of 3x3mm Sq balsa sticks.

2. Lay the plan on the the building board and put a clear cellophane sheet over it to protect from glue.

3. Cut the approximate length of the sticks, ( keeping half an inch extra is a good idea for adjustment). We would do a Dry fit before actually pasting the stringer.

4. Place F11 and F14 at their place and pin the sticks flush tight against the notches on the formers (LowerAftFuse1.JPG). Remember to put spare 6x6mm Sq spruce between the plan and the stringer sticks as the notches for 3x3mm spruce is further up on the former after that for the 6x6mm sq vertical 'piller' we would put later.

5. Now place the Former F12 and F13 and put the remaining three stringers. (LowerAftFuse2.JPG)

6. Use a set square to ensure the formers are upright. Mark the stringer for a final cut. Preferably use a Miter box and Balsa razor (Xacto/Zona etc) to get a perfect cut.

7. Place the bottom stringers, mark where the formers would intersect. Put PU/PVA glue at those portion and on the notches on the former.  After 5 min wait, put the formers in place, using the set square to ensure they are upright.

8. Once the glue is set, paste the remaining stringers.

very impressive.... Keep it up

knock - knock.... anyone still building???

Thanks for showing interest! I was holding my further photos before some one actually shows interest. I would surely update once I reach home and have access to build pics...

Hey!!I love to build, so am always interested in someone doing a good build log..

We would now glue the side fuse panels on which the wings would rest. I have modified these side panels as the slot for wings was not shown in the original plan. As my coral draw is out of trial period, I cannot confrim whether the side panels are there in the files.


IMG_3004.jpg --> The left side panel pasted
IMG_3008.jpg --> The Right side panel pasted

Note that i have used a paste of Fevicol and fine sawdust to provide reinforcement at the join edges. This gives tremendous bonding at least weight. Bit ugly,  but works as charm!

We then prepare the vertical beam at the tail end which would hold the longeron and the bottom turtle deck (or what ever you call) together. This beam would also support the Rudder and the Tail Wheel. Note that you must use a Set square (even cheap plastic ones should do, metal ones are much handy) to ensure this beam is perfectly perpendicular to the Longeron axis. Not doing so would result in slight oblique pitching tendency from rudder inputs.

IMG_3230.jpg
Finally attach the bottom turtle deck we prepared last time.

The trailing edge of the Fuse side panel needs special treatment to give fitting curve to the former. We would discuss this in next post as we can post max 4 pics per post.

Hey Ujjwal,

Very nice built & detailed explanation.

Please post the pics of wing construction too.


All the best

Keep the formalities aside - your presence is needed to finish this model.... Be the Tommy Hilfiger to this 'Model' and put together its apparel .....
