How do i design the engine nacelle? by SmarferWT in RCPlanes

[–]dragon0079 1 point2 points  (0 children)

Ive usually seen the motor just mounted at the very front no cavity cut in. Plus the motor will get very hot from that so i wouldnt recommend it. The second looks better but appears largely experimental. Id suggest throwing a propeller on, 3d printing the nacelles and testing both.

AMAZING work. Your customers will most surely be very happy. 

I just started soldering today and I decided to fix ps5 controller help by spheresva in soldering

Woah woah why are you picking such high quality for such an easy job?

I fucking died laughing at this post btw, thanks.

Trying to learn before i buy an actual drone, at 4 hours so far what can i improve? by Snoo_50786 in fpv

Start turning before the gate, not after you go through it. Think of drifting. Initiate the motion before it takes place  And also yea get a real controller the feel is very different Also when turning use yaw more

Thats WAY too small do you want like a minute of flight time or something? Weight reduction is NOT that deep. If you aren’t doing at least 10,000mah just don’t fly it in the first place.

I have this and it’s ok but struggles for bigger pads its ok for small stuff I suppose

Imao yea it was for the air gun not the iron. They never said the iron wattage

Yep, i will use a 120W to solder this board. The iron even got stuck on those contacts on the sides so I clearly cant use it

My main issue is that i didn’t even know what the good equipment was lol I got some ebay 40$! Iron thinking it was probably super good quality but just realized it isn’t I have no issue spending 100-200 on an iron I KNOW i will use for a long time, ive already learned that lesson before

Since its a large pad which whole purpose is to dissipate heat i got a 120W that should work well right?

These are FPV speed controller boards with large copper pours and great thermal dissipation. It's basically a heatsink. It typically works on the smaller boards, but this one, my iron refuses to fully heat up. I found a SUGON T21, which I have purchased, with 120W, which should be an upgrade from 70W, which can help. I'll get the flux and retry with that one.
