Default Optimal filament materials for our RC helicopter hobby?

I am new to 3D printing. There are several types of filaments. PLA seems to be the most popular. PETG seems to be gaining popularity.

What types of filaments do folks use to print parts for our RC helis?

Learn to print with PLA as it's the easiest filament to print with. I exclusively use PETG because it's able to withstand the elements and chemicals (nitro), but it's a bit more tricky to print with. If you don't plan on using printed parts on nitro helis, try Matterhackers PLA tough. It's easy to print with like standard PLA but has much better strength. Some other brand PLA+ material are good.

Different materials have different properties, thus there is no "right" material for everything. I have used so far ABS, ASA, Nylon, PETG, PETT, Amphora, and TPE. And for prototyping, I always use PLA.

For example PETG is good for lots of things, but not super strong.
Nylon is slippery and wear resistant, but is slightly flexible. Amphora (HT) can withstand high temperatures and is very strong, but very difficult to print. ABS and ASA are great for parts that need further sanding and drilling. Etc.

If your printer doesn't have a heated chamber, you are probably going to use PLA and PETG exclusively, as most of the engineering materials require >60C chamber temperature, and nozzle temps up to 300C.

I ordered the "Original Prusa I3 MK3S". This will be my introduction to 3D printing. I also plan to make an enclosure for it, but I need the printer first so I can generate the necessary 3D printed parts for the enclosure. My guess is this will involve a steep learning curve with lots of trial and error. Thanks for all your help.

Prusa is certainly the best first printer. It will keep you busy for a good while. Start with PLA, and learn the basics. Once you are comfortable with PLA, then you should try PETG and the others. No hurry with the enclosure... the basic printer should keep you occupied for some time!

Enjoy the journey

1.6mm nylon fishing line,, cheap and tought, , but it needs prepared to remove air ( last I remember is in oven for 2 hour at 150),, also it will be under extruder since it is only 1.6mm , needs extruder 120%,, last is edit firmware , most stock printer can not go over 260C,, have set my to print at 295

PETG is my preference for most things. If I need something particularly strong, I use carbon fiber PLA with a hardened steel nozzle. I have also used carbon fiber PETG, but I think carbon fiber PLA is stronger. ABS is also strong and is the lightest by volume but works best in an enclosed printer.
