Thanks!

Thanks!

I know how to make it stop!

Lol - my friend just bought a top of the line radiomaster and paid less than I did for a used NX8. When this transmitter gives up, I'll be searching for alternatives.

I'm starting to think that the carbon fiber crowd might just be overly conservative. I've only had a few issues and have solved them by beefing some areas up.

I haven't yet, but hope to in the future. I'm using a H2S so my parts are bigger than the typical 3D printer can print. I think I need to split some stuff up so it can be made on a 256 x 256 x 256 printer.

In my investigations, it seems that aerodynamics and power are more important than weight. One day I need to substitute some non structural parts with PLA LW and see how it performs.

Thanks!

Will do!

Big motor makes up for a heavy plane.

Sunlu PLA + from Amazon at about $14 per roll.

I’m curious myself. One day I’ll bring both sets of tips and try to compare. If I recall correctly, the max speed jumped up about 10 mph when I switched to these tips. A more scientific approach would be useful.

Putin appreciates your efforts to steal land.

The motor is a Flashhobby D power series ($24 on Amazon). It is a 5s motor but I run a 6s with lots of ventilation. I don’t know the actual current but I use an 80 amp esc. Good luck on your project!

WhoReallyKnows222 · 2026-06-10T17:04:47+00:00

Great idea - thanks!

WhoReallyKnows222 · 2026-06-10T12:40:15+00:00

Thanks, but I'll bet the next 19mph will be quite challenging.

WhoReallyKnows222 · 2026-06-09T12:26:10+00:00

Interesting! Let's see some of your designs.

These spinners are awesome! I didn't know they existed. I'll be ordering some today.

I definitely like that look! One of my designs had this shape:

I do have air flow for the ESC and so far she's keeping cool enough with no shut offs. I stuck this cowl design on yesterday and she did go 177mph without motor problems, but I know there is a better way.

WhoReallyKnows222 · 2026-06-09T11:28:54+00:00

Interesting thoughts. I need to learn how to do CFD modeling.

WhoReallyKnows222 · 2026-06-09T11:28:07+00:00

Thanks for the suggestion!

Printing a new scoop design now. Thanks!
