Hi,
I've recently acquired an old methanol motor from an rc plane. I've fixed it up, but the tap where you screw the glow plug into the engine head is not fully functional anymore. A dealer at my local hobby shop told me that I could use teflon tape to fix it, by winding it around the glow plug and then screwing it in.

I've read that teflon starts to decompose and release toxic fumes when heated over 260C° and also when in direct contact with a flame.
I wanted to know if this would be a safe method to fix the engine or if I'm about to poison myself with teflon fumes.

It would be nice if you could help me out,
Hugo s.

Hi everyone who is looking at this thread,
I'm building a race quad to replace the first one, which I crashed so badly the gyro in the flight controller, the ESCs and motors broke.
I want the quad to be light, to fly a decent amount of time (~20 min) and to be fast. I'm opting for the Druckbär ultralight 4 race quad frame with the adaptor for 30*30 electronics. I'm planning to fly it on my cc3d flight controller and BL Heli s LittleBee-spring 30A Dshot ESCs since I have them lying around and don't want to buy a 4-in one esc. I'm sure I can mount them to fit the frame.
This leaves one question: which motors to use. Since the motors used on my first quad are broken, I thought I might as well get different ones to see how the performance differs. I've spent a while searching for good motors but haven't found any good ones.

I'd appreciate if some people could share their ideas and experiences with different motor brands and types, so I can have an easier time chosing the right ones.

Thanks Hugo secondname

PS the drone is supposed to run 5'' gemfan hulkie props.

Hello, I have a little problem:

I have acquired a cnc mill and would like to cut out an airplane kit for a DeHavilland Beaver. The plans are in a pdf format.
My cnc software is CNCjs and only takes g-code files. I've taken the pdf and cut out the part with all the parts on it, that need cutting out.
My problem:
I need to turn this pdf file into a g-code file. This has proved quite difficult for me, due to the fact, that the converted g-code file doesn't show the parts, but only seemingly random rectangles, triangles and other shapes.

If you need any extra information, feel free to ask.
