VTOL on rc jets

[BreydonsRc]

Vertical takeoff or landing is one of the most advanced ways to takeoff. What if you added it to rc planes? The f-35 lighting is a jet that has vertical takeoff and is one the most underrated jets made. Under the plane could be a fan that blows the light plane up in the air. You could flip a switch on the controller enabling the vertical takeoff. What Is your opinions on this topic?

Top Gun just popped into my head

Sounds cool. But only if you build it. I’m too stupid to figure it out

Well just get some Styrofoam, tape em together into a shape of a plane and that would be your first step

Super glue it all together will be 2nd step

Oh wait, jb weld it would be better

 

[BreydonsRc]

Super glue it all together will be 2nd step

Then "accidentally" crash the plane then do it all over again

I might be dumb but I’m not that dumb

Yet.

It's Styrofoam, whatchu talking about?

SPACESHIP

That works too

Use some Kragel super glue

Put wet fruity pebbles on it and let it dry up so they will stick together

I think the biggest problem you'll run into is the relatively low static thrust of EDF's, compared to propellers, if you mean to really emulate the lift fan and swiveling rear nozzle of an F-35.

EDF jets generally have a thrust to weight ratio lower than prop-driven planes until you get up to high speed and the propellers run out of pitch speed before the EDF's run out of efflux... This isn't to say they're less efficient, 2 grams of thrust per watt at 60mph is the same efficiency as 6 grams per watt at 20mph.

The problem is you'll still only be making those 2 grams of thrust per watt at a hover. A multirotor can achieve 4-6 grams per watt of lift, and an RC plane can achieve 10 grams of lift per watt in level flight.

There's more efficient multirotors and less efficient planes, but a hovering EDF would devour even the best batteries in 2-3 minutes of VTOL, and only achieve a few minutes of flight in between.

They already make it. It's called a drone.

Thanks for this. Was just about to ask somebody if they could put this into kid terms

This guy is onto aomething.

This guy is onto aomething.

that is slick, the flight video is even better!

This guy built one too, and it just pulls off a 3-minute hover.

Didn't know they already made VTOL rc planes

What? Says the kid that knows everything?

Yeah, I didn't either. Interesting thread kiddo. I learned something
