Diese Idee ist echt gut, mir kommen da noch einige Ideen für einen Hauptholm aus Holz/CFK. Warum hab ich all die Jahre an diese Art der Konstruktion nicht gedacht? Nice days from Germany!
Thank you for watching. I wasn't the first to develop this method of making foam wings but I feel I have come up with a few processes that have worked for me. The hobby like so many other things are developed by building on and improving other people's accomplishments.
I use a drop jig. It's a 1/8 music wire that's heated with a torch and free falls through the wing. There is a video on my channel showing its use. Thanks for watching.
Your work is amazing! Please, after you finish the wing panels, how do you join them together? I have made two panels here but not sure of the proper way to finish the wing.
The coring templates are made from phenolic purchased from MSC industrial supply. Formica countertop material can also be used with good results. Thank you for watching.
can you show a weight comparison before cutting the holes out (whole foam core) and after to see how much weight reduction is there. Is the strength the same after cutting?
That is a good idea. I have another wing I'm about to do and I will make a point to include that information. I feel that the strength would be the same since the carbon spar carries most of the load.
There is a vertical slot cut for a spar that I will cover in a future video. Both wings are glued together and fiberglassed in the center section and glued into the fuselage as one piece. Some designs have the wing removable. Thank you for watching.
For the average flier probably not but for the competitive flier it is. The other advantage on this wing build I used 8 lb regular hobbyshop wood to reach a competitive weight. The leading edge sheeting is 1/32 balsa instead of 1/16. I still love the look of the classic I beam wing though. Thank you for watching.
@@paulbizard3493 Not sure of the exact percentage. If I remember it was usually around 25 to 30 percent. With control line it is also necessary to core the wings in this way for leadout clearance. Thank you for watching.
Salve, davvero complimenti ha fatto un'opera d'arte, quella macchina taglia polistirolo ho provato a farla pure io ma non abbastanza efficiente, ho rinunciato. Mi piacerebbe tanto avere un vicino di casa Maestro come lei per imparare. Grazie del suo video e complimenti ancora. Ha un video dove fa volare questo modello che ha costruito?. Io sto facendo uno Spacewolker 1750mm apertura alare in balsa, è la mia prima costruzione
Thank you for your kind comment. I believe a more in-depth video on the foam cutting machine is in order to clarify the set up and adjustments. I will try to add some flying site videos in the future.
The spar is inserted into a slot that is cut from the top to the bottom of the wing where the vertical foam spar is at the high point of the wing. I should have shown this step in this video. I will make a short video showing the fixture that cuts this slot. Thank you for watching.
Thank you for watching and commenting. For a competition airplane where weight is measured in grams every little bit helps. It does take extra effort and time but one reason these wings are cored is to allow clearance for the leadouts. I have built many R/C airplanes that do not have the wings cored.
I agree about the amount of work but I feel I can make a more accurate wing with attributes I couldn't obtain otherwise. Thanks for watching and commenting.
