Thank you to all those who contributed. BAS

Hi Simon, if I understand you correctly; 'You need to use a CAD file to load the GRBL software' !!!!!! I thought you needed 'Gcode' to direct the Laser.Where do I get one of those? Can you elaborate please I thought the laser software was for just that.!!!!!! Bas

Hello, I dont own a laser cutter, as yet. I am not very tech so the software/programing is a cause for concern. In an effort to find out more I downloaded the free software with a view to see what I could do...... I managed to download a picture and played around. What I cant seem to do is to draw a shape say a rib with the intention to prepare for cutting. But I cant find out how to do that !!!!!. Can anybody give me some guidance please. It keeps telling me that I am not connected!!! Thanks in advance Bas

Jon, thanks for the offer but I dont have the confidence to rebuild them. Many thanks Bas

I am looking for a '61' if you have one available please. Regards Bas

Hello again, one last question; It seems that I need to be in possession of a Laptop in order to drive the cutter. What size memory is required as a minimum and will any old laptop function with as Ron has suggested with say Lightburn? I am trying to learn from scratch so have a lot of ground to cover and ask what are stupid questions.Thank again in advance. something has just occurred to me, how do you keep the material being cut flat on the bed, I have seen some clips but they only work on mesh, what about the slatted bases? Bas

Thank you for your comments, but one last question for now!!!! Does the software contain a library of possible 'Shapes' etc. Can you upload a shape and the software sorts the code itsself? Many thanks Bas

Excuse my ignorance but apart from the cutter, am I correct in saying you really need an 'Air assist' and a 'Mesh/honey comb' base? Apart from asking there does not seem to be anywhere that gives the full story of requirements. I assume that you need the mesh so as not to burn into the bench. There is also , I assume some kind of fume extractor connected to an enclosure..... seems to be the logical requirements. Bas

Hello again Ron, this must seem stupid question but from what Ive seen you cant load the 'Machine' with the software, as it has to be run by a connected computer source such as a laptop . I only have a desk top, not so portable, is it not possible to run the info from a 'Data stick' of some kind or must it always be run thru' a computer.I have an iPad can you run it thru' that, as its portable?. Sorry if these are stupid questions. Thanks and kind regards Bas

Thanks Ron, I am way ahead on you by nearly a decade. I am not computer 'Blank' but not a wiz kid. What I have seen of some soft ware the straight lines are logical. How would you instruct say a regular curve, ( seems more uniform ) or a non regular curve, thats what bothers me , as you have to have to quantify it in the first place!!! I can envisage the code being somewhat logical, whereas the latter surely need lots of points of reference , or is the software have some logic?. Thanks in advance Bas

I have been looking at the subject of lazer cutters for a long time. They look and sound like the bees knees. What really bothers me is the actual 'Programming'. How 'Smart' do you have to be to enable this part of the technique ? I am of the older, older generation, not a complete idiot with some computer knowledge, mainly as a user rather than support. I am very interested if I could get some comments regarding the software and process. Is it possible to 'Try' the software , prior to buying a cutter, to see whats involved ? Bas

Thank you David for your reply. I have some really old models but alas they dont like wind . I have some Ben buckle kits that I have aquired along the way.Theres just some thing about them. Many thanks Bas

David, re the Radio Queen...... I was given to understand that these older design models dont perform well in anything other than a breeze. Is it better weather over there in France or does the radio queen buck the odds on that issue. How does that sort of airframe fair when exposed to the rigours of Training. That goes for the holigan as well.Thanks Bas

Thanking you all for your input. Bas

Can some one tell/ advise me as to what I can cover my plan when building over it. Cling film and several others are OK when using water based adhesives but I have taken to using Cyano of late and they attack what I have been used to using so far. I hear that Cellophane is a possibility ! What alternatives are available , freely, with thanks.Bas

Hi again, I now understand what wash out is. Usually If every item is a good tight fit on dry asy , I can go round with the Cyno. So if thats the case with the wings in question, I can pin to board raising the rear of the wing tip , in my case by 1/4", then add cyno. The wing edge is only pinned on the LE and inner TE. Assuming that its flexible enough to get the twist that is!!!!!.Bas

Thanks Ernie, so the measure of 2 degs is along the wing tip, not the wing length?? Makes sense, thanks. What do you do about the Ailerons, I had presumed that they would still be in line with the rear wing edge as normal. bas

I have to build a wing with 'Washout' according to the article. Question one, how do you do this? Second ; How do I measure 2Degs of washout, or put another way how do I build in 2 degs of W/O for a wing thats 31" in length (each wing)attatched to wing stubs already present? What about the ailerons, as they cover half the wing length, surely they must show the same characteristics.!!!!! Build wing first then make to fit? Bas

Its a BT router , think it uses both freqs. Bas

My BT router wont work thru' walls, had to use an adapter that transmit thru' the mains wiring.Bas

For the Optica build the motor is to the rear of the CG, Battery to the frontish( Lipo more wt than a motor) Sorry did not say that before Bas

For the model in mind I can place the battery almost under the CG, well not quite . Bas

I am going from 61 IC to electric.Bas

Thank you to all those that contributed, Bas

I have never been involved with IC engines and need some advice...... I am trying to find the weight of a tank and fuel that would be used for a 61 motor. This is to help plan a build in electric what is on plan as a 61 motor. I am aware that the choice is rather open to choice or what space dictates. Many thanks Bas
