Chris Walby Posted August 3, 2018 Share Posted August 3, 2018 Very nice Martian you have done a cracking job and expect generated a lot of interest. Do you have an idea of gear you will be using and what's the published AUW? Thanks for the great work. Quote Link to comment Share on other sites More sharing options...
KiwiKid Posted August 4, 2018 Share Posted August 4, 2018 Posted by Martian on 29/07/2018 12:23:01: A 3d printed plane will deform if left in hot sun or a closed car in the sun . Sure will, I have seen some moderate examples at the club field - these two are a bit more extreme The build is going well Martian - keep at it!

Biggles' Elder Brother - Moderator Posted August 4, 2018 Share Posted August 4, 2018 It looks stunning! Very interesting indeed. BEB Quote Link to comment Share on other sites More sharing options...

Thanks for the great work. published AUW is just short of 2Kg with a 3s 3000 lipo all hardware etc is linked in the instructions the can be downloaded from Aerofred or 3Dlapprint all are sized to fit the print bay and are from Hobbyking.

Martian Posted August 7, 2018 Author Share Posted August 7, 2018 Thanks BEB ..completion with all servos and control runs etc have been halted while I have been building my printer plus I need some 3mm piano wire for UC legs Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted August 7, 2018 Share Posted August 7, 2018 Progress looks great Martian, but can I just ask you to rewind a bit - to the part when you said that a 3D printed plane will deform if left in a hot sun or in a closed car. Doesn't this rule 3D printed planes out as a practical option? If not, what precautions are you planning on avoiding them getting hot - or are there different printing materials available with different melting points? My shed can get pretty warm in summer and my car certainly does when parked up. Quote Link to comment Share on other sites More sharing options...
Martian Posted August 7, 2018 Author Share Posted August 7, 2018 It depends on the melting temp of PLA but ABS has a higher melting point , I will dig a little more Quote Link to comment Share on other sites More sharing options...
Slickriff Posted August 7, 2018 Share Posted August 7, 2018 I seem to remember seeing mention of a version of PLA that is sufficiently more thermally stable to make it not really an issue. It may have actually been on the Aerofred website. Quote Link to comment Share on other sites More sharing options...
Martian Posted August 7, 2018 Author Share Posted August 7, 2018 PLA melts at between 180 degrees and 200 degrees but it varies between manufacturers and softens between 70 and 80 degrees , even a car interior can distort in high sun Quote Link to comment Share on other sites More sharing options...
