Try to use diabond for the arms and 3/2mm plexi fore the rest I like the fluor orange collor(im dutch!)

Thanks for the updates. I think this is why many others have tried and failed in the past to make quad frames out of anything but carbon fibre that has the required strength and durability. Even if it seems strong and durable on the bench, it usually just breaks easily on the first crash. You may end up having to resort to milling your designs out of carbon fibre board. I guess we will wait and see if you have any success with other materials which don't need to be excessively thick or heavy in order to achieve similar strength/durability as CF. I will continue to watch your progress with great interest Posts: 6,104 Threads: 172 Likes Received: 2,283 in 1,830 posts Likes Given: 4,730 Joined: Feb 2019 Reputation: 100 https://www.fpv360.de/epages/80602151.mo...cale=de_DE he use some gfk, i saw how the frame performe, its rigid and have a decent warranty. the only working alernative material i know. • Posts: 385 Threads: 23 Likes Received: 62 in 36 posts Likes Given: 105 Joined: Aug 2019 Reputation: 2 Hugnosed bat thanks for the link ! yes gfk reminds me of when I was young and sporty ?built surfboards of 6 kg while everyone still sailed with boards of 20 kg have experienced the new carbon fiber era up close Im looking for a easy to mill product Dos not have to be the strongest product The fluor plexi glas i can look at the whole evening and still like it Wr Henk Posts: 385 Threads: 23 Likes Received: 62 in 36 posts Likes Given: 105 Joined: Aug 2019 Reputation: 2 08-Jul-2020, 07:59 PM (This post was last modified: 08-Jul-2020, 08:01 PM by Smokie.) it stole my heart milling went bad today all kinds of mechanical problems (loosening bolts as result of vibrating etc) have adjusted the model of the arm proto model fitted accurately and is strong enough I think pyrasied, there are wool threads in it have to wait for further material samples I can trim my cnc machine in the meantime Wr Henk Posts: 385 Threads: 23 Likes Received: 62 in 36 posts Likes Given: 105 Joined: Aug 2019 Reputation: 2 milling went a lot better today speed increased and feed slightly lower no post-processing necessary, it is nice to see the accuracy wr Henk Posts: 385 Threads: 23 Likes Received: 62 in 36 posts Likes Given: 105 Joined: Aug 2019 Reputation: 2 Posts: 385 Threads: 23 Likes Received: 62 in 36 posts Likes Given: 105 Joined: Aug 2019 Reputation: 2 13-Jul-2020, 08:03 PM (This post was last modified: 13-Jul-2020, 08:05 PM by Smokie.) today i made a proto for a frame part needs to be adjusted hope that the dimensions are so that I have no props in the picture am not yet a supporter of a dead cat configuration Wr Henk Posts: 385 Threads: 23 Likes Received: 62 in 36 posts Likes Given: 105 Joined: Aug 2019 Reputation: 2 not as smooth as before it turns out that it is polycarbonate , what has been extruded and is much more difficult to machine material melts around cutter and causes all kinds of problems so some other material ordered as a replacement I am now done with the design of front wr Henk |
