Steve, What leads you to expect the EDF to consume 100 Amps?

Oooops: For "Fusion123" on my last offering, please read "Fusion 360". It's my age.......

My tuppence worth…. I think Roger Jones 3 is slightly mistaken, Martin Harris answered the question at his 03/02 18:39 entry suggesting production of a reduced size object of the original, turning it into a "hole" and carefully merging it with the original to produce a shell. All easily done on Tinkercad though great care has to be taken with dimensions and positioning prior to merging. I discovered this process for myself during the initial lockdown and used it successfully for producing a…… hollow canopy! Following on from that, I explored 123D Design (free to download but no longer supported I believe) and Fusion 360. I found these two could do pretty much whatever I wanted regarding 3D print design but the down-sides were complexity of use and being not particularly intuitive; unlike Tinkercad. There is a wealth of online tutorials and I spent the later lockdowns trawling slowly through the "how to's". Worked for me. My current modus operandi is to do the fundamental design work using Fusion 360 (can be done using 123D Design as well), export the .stl files to my pc and then pick them up on Tinkercad to complete the job. That process may not appeal to the purists but it works for me! I find the Fusion 123 "lofting" and "shell" functions to be particularly helpful; the latter does away with the need to construct and merge the Tinkercad "hole". My current lockdown project is the conversion of a hand launched pusher-prop design to (finger saving) EDF using Tony Nijhuis's favourite 50mm FMS EDF unit. Not completed yet but going well. A photo is included showing the 3D printed EDF assembly bolted to the rear of an appropriately truncated balsa fuselage. Max thrust measured so far is ~520g on 3S.

Has anyone tried 3D printed stand-offs and/or boxes? Obviously structural considerations to be thought through but exact size - no problem!

A school chum of mine struck back - ONCE. He carefully hollowed out the core of a chalk stick with the point of his compass and filled it with red match heads; carefully concealing it all by packing the open end with some of the powdered chalk he'd generated. He placed his loaded piece beside the blackboard shelf having first removed all the others. Next lesson, the teacher scribbles vigorously on the blackboard and, as a result of the friction, surprise, surprise, the chalk bursts into flames and burns the teacher's fingers. It took the teacher a microsecond to fathom the culprit's identity; it was more than a blackboard rubber that headed his way!

Season's wishes everyone, stay safe!

This might help cure my feelings of being a mushroom....?

To win this one would be absolutely phantasmagorical!

With all due respects, it is does not correspond with Salisbury Cathedral's structure; used to live just down the road from it.

I don't understand why you guys are ignoring Mode 3 - the mirror of Mode 2. I am left handed and it has always worked for me. It was my initial set up way back with my 27MHz Fleet gear and, being LH'd, seemed the most logical to me. Still does!

FAO Fun Flyer, sounds like you have an ideal set up. I would be most grateful if you could let us know what set up and hardware you employ etc. Many thanks.

.....and ours.........

Experimental error Simon? Suggest try again a couple more times to consider the range of results. Talk Sunday.
