r/RCPlanes

Previously, it was discovered that in the oscillatory mode the aerodynamic support of the air can increase up to six times equal to the blowing data in the wind tube. In addition, it turned out that the direct flow of asymmetrically moving bodies in the country cannot be easily explained by Newton’s third law, since the flow occurs in the direction where the body moves towards the middle.

Further experiments confirmed this, and on its basis a hypothesis was put forward: this type of turbulence (swimming fish and bird flight) vicoristic energy of the collapse of the vortex wake. In fact, the thermal energy of the superfluous medium (Brownian ruch) is the result of the direct process of self-organization of molecules in the vortex. This reveals a new look not only at vortex dynamics, but at fundamental physics as a whole.

However, this will require further research, and the problem of creating an efficient and wear-resistant drive remains unsolved. My opportunities not enough for this.

I've decided to retire my Vulcan after an unscheduled rapid disassembly this morning. It was my first EDF, and our time together was... rough.

I started on an Apprentice, then got the Vulcan (70mm 6s), then got a T-28 (1.2m 4s) (I know, I'm out of order there).

I'm trying to decide how to move forward. I don't want to give up on EDFs, but I struggled to fly this one so much, getting another one right now just feels like throwing money (and my confidence) into the fire.

Anyone have a recommendation on a prop plane that would make a good next step between the T-28 and an Avanti? Maybe something that'll help me get used to the higher speeds & less forgiving turns? Perhaps a P-51?

Edit: The plane really isn't recoverable. I've rebuilt it before, but the damage is BAD once you get close. I'd spend as much on parts as a whole new plane.

Edit 2: gonna try and put it back together. Figure I don’t really have much to lose at this point. Thanks for all your help guys!

After 4 years flying my EDF’s shown, Turbo timber Evo and carbon cub S2 I decided to try this one out after watching Brian Phillips rip his on YouTube and I recommend this to everyone brand new to the hobby or 10 years in. It is 10x easier to control than the Carbon Cub S2 and I had so much fun on the maiden flight tonight. Straight into inverted flight the rudder control is pristine.

So i just (almost) made this pylon racer thingy and i just wanted to ask are there any obvious mistakes with it. (Ignore the detached motor and servo cables).

Enjoy a small video of the Fokker dr.1 maiden flight. Messed up the landing a bit... Put in half speed and it looks great!

Rate this aircraft and tell me what you would add to it.

I never work on planes with the prop on but I got lazy tonight. I was testing the throttle and it tipped my stand over. I instinctively grabbed the plane to prevent it from falling over and bam broke the prop over my fingers.

A while ago I posted about the Spark #1 I had built from Bavafil Olefin (the red one), which worked out well and it's a fantastic plane. But there was room to grow. While #1 came in somewhere around 750g, it was cool, but lacking punch and energy retention.

So physics dictates that more weight is more faster. I built one in full Sunlu PLA+ 2.0, bigger motor, higher pitch prop, higher voltage.

#1: Sunnysky 2212 1250kV, 8x6 Aero-naut CAM, 3S 1000mAh

#2: Sunnysky 2220 970kV, 9x7 Aeronaut CAM Z, 4S 1300mAh

The changes are DRASTIC. Firstly, it no longer glides as well, it sinks A LOT faster, but that was expected. But now we climb vertically and straight line speed is up A LOT, too. It has good energy retention and punching this thing straight down from 200m through a low pass is insanely satisfying. The whistle is addictive. Stall behavior is still well mannered, but landing without spoilerons is not a good idea. I needed the entire 150m runway and then some to go from less than .5m in altitude to standstill. With spoilerons, it cuts it in half, but it still needs a long approach, which it shares with other hotliners.

If you have a 3d printer, this is easily one of the best planes to print. It sits at the sweet spot where it's already serious plane, but not too much hassle to reprint if the inevitable happens. I 100% recommend it, both versions are great.

Edit: Sunlu PLA+ 2.0 is just above 10€/kg, so this plane prints for just around 6€ :)

Going through a bunch of A160 RC planes today. Some need repairs, some need parts, and a few just need to be put back together.
I’ve been spending way too much time working on these little planes lately 😂
Anyone else here fly the A160? What usually breaks first on yours?

Costs about 150 in usd it's missing hall effect gimbals

I have also been looking at the radiomaster boxer 4-in1
