Hi Juan
For IC plane I will use ONLY bolts, 3 bolts for the belly pane and 4 bolts for the canopy.
Here is what I did on my Oxalys

Hi Isaac,
See you have been quite busy since I have been away! Great progress and attention to detail.
Regarding the honeycomb you are using, please could you let me know what thickness it is, and also whether you vacuum or press. Another question - do you run 4.8v or 6v systems. I am looking at putting in the 6v as this seems to be the trend to get the most out of the servos, using the Jaccio switch and regulator.
Thanks
Roly

Here is the link to the manufacturer of the honeycomb:

These are the materials I use:
LP-21 1/8" Graphite/Balsa 225g 12" x 12" $28.00
LP-31 Glass/Nomex Panel 1/8" Thick x 12" x 24" $30.00
LP-37 Glass/Nomex Panel 1/4" Thick x 12" x 24" $30.00
LP-40 Carbon/Nomex Panel 1/8" Thick x 12" x 24" $41.00
I am going to use the ThunderPower Prolites 7.4 V 730 mah (TP730-2SPL) and PowerBox Digi-switch:

Isaac, amazing work.....
Evry day when I arriving home, the first thing that I am doing is open this wonderful thread.
I fnished building my Eclipse (CA MODELS) a few weeks ago.It took me two year beacuse I did not have any experiase with F3A building.
Now thanks to you and your helpful pictures I understend how things need to be done in the best way.
By the way I bought from a friend a CAPRISE that isaac build a few years ago and let me tell to you all that perfection is no stange to him.Even after 8 years of flying this plane looks like new.
The amount of effort that he puts in his plane is unimaginable.
I am very glad that we have some one like Isaac that is willing to help others and promote F3A here and in our counrty.
And like my friend AMRAM said, we are all inviting you to visit out county and enjoy those many wonderful places we got.

Izik,
I have a question:
What will happen if after cutting the 2 holes instead of the weight drops 2 grams it increases by 2 grams? How will you glue them back? ;-)
And a serious one: Aren’t you concern about affecting the fuselage structural strength
by cutting these ventilation holes so rear on the fuselage itself and not like we did on the ballypan on our Oxalys?
As expected at the beginning: This is a Masterpieces post.
Any F3A Pilot any where in the world should <START HERE>

Hi Amram
This is the stiffest place of the fuselage (under the wing tube), I cut the bottom of the fuse, no the sides of the fuse, so I don't think it will affect the structural strength.

Hi Isaac,
These last photos of the wing root - did you add the balsa for final fit i.e. sanded to follow the contour of the fuz?
Thanks
