AMAZING: an RC JET (real jet engine)-really fast!!

Holy Cow - Here is a link to an RC F15 jet that is using two real miniature pulse jet engines. This thing is freaking amazing...

Imagine taking this thing to the local RC plane - strip. Then powering up the jet engines....

3 posts down I posted several more links to RC jet videos

I can't believe they can control it while it's going that fast! I can't imaging trying to land that thing...

WOW.....that thing needs onboard video

DarkLight He he here is a jet with an ONBOARD video camcorder...

Or here even better, an RC jet with a WIRELESS cam that provides overlay speed, altitude and heading data...

Oh and regarding speed, check this out: here is fairly boring video for the first 9min and 24 sec. However starting at 9min and 24sec, the clip shows the flight of an RC jet that is mindblowingly fast... also looks like it was built for speed... My favorite one however is still the first clip I posted in this thread. The overflights look like straight out of top gun.

Or here is a B52 with 8 pulse jet engines...

and here the crash of the same B52

Here is an RC Eurofighter jet 9.5min video (really cool here are the tight turns and the slow fly-by's with flabs engaged (a nice one is at 6min into the video)

Awesome, Thanks for sharing these mobile1 /ubbthreads/images/graemlins/wink.gif

Re: AMAZING: an RC JET (real jet engine)-really fa

cool!

Re: AMAZING: an RC JET (real jet engine)-really fa

I would love some details/drawings/etc. on the engines...

Super videos.

Re: AMAZING: an RC JET (real jet engine)-really fa

Indeed. Thanks. I have seen the bomber one before, but the others are insane. Fast.

Re: AMAZING: an RC JET (real jet engine)-really fa

there are a lot of model jet planes out there
pulse jets are okay but the mini turbojets are kooler.
there are mini turboprops and the turbine engine powered helicopters are really kool.

I have a mini turbojet engine with full kerosene autostart(no propane)(30 pounds of thrust)

Re: AMAZING: an RC JET (real jet engine)-really fa

Actually the B52 was NOT pulse jet powered, it had 8 turbojets, and that represented an investment of about $25,000. Range and time aloft on the model was limited because the UK limits the maximum weight of a model aircraft to 150kg, or 330 pounds IIRC. The model apparently was 315 pounds empty.

Re: AMAZING: an RC JET (real jet engine)-really fa

I kinda knew the b52 was not a pulse jet

I never looked at any of the links to any videos

I have seen them all before


the model jet speed record is around 265 mph

my engine cost me over 3200.00

Re: AMAZING: an RC JET (real jet engine)-really fa

none of the videos posted here are planes with pulse jet's

these videos are all turbojet powered planes.

Re: AMAZING: an RC JET (real jet engine)-really fa

Those r/c jets are amazingly fast. I actually saw some (maybe it was only one....) fly last year at the Miramar Air Show. I can't remember exactly how fast they said they were going, but I think it was around 200 mph. They also had that jet powered semi-tractor running there. Cool, cool stuff.

do a google search for alan szabo

world class heli flying

Re: AMAZING: an RC JET (real jet engine)-really fa

I saw some world class heli flying there, too. Not as much fun to watch as the jet, but it probably a lot harder to do what the guy was doing.

Re: AMAZING: an RC JET (real jet engine)-really fa

OK, I was going to not say anything, but I can't seem to control myself.
In the first video, that F15 isn't as fast as they would like you to believe. The video is played back at twice normal speed. When somebody hand holds a camera and follows a moving object, they don't keep it centered in the field of view. It gets away from them, they notice it, catch up, overshoot a little and the cycle starts over again. Every one of them seems to be about the same frequency. When something is shown in double speed, that jerking motion is also speeded up. Look for it in that first video, compare it to the last video of the Euro-Fighter. YES, I know the video in the Euro Fighter is smoother. Ignore that, look for the tracking jerk frequency.

Also every time I see that moron stuff the B52 into the ground, I get sick to my stomach. I've posted about this before. It was pilot error. It is a gray plane in a gray sky. He took off, let the plane get too far out, started his turn to the right. He completed a 180 turn, rolled out to where HIS WINGS WERE LEVEL (a no-no when far away) and flew straight for a while. This was on the downwind leg of the pattern. He was in bad visibility and too far out to fly with his wings level, giving no feedback as to his roll position. The plane rolled to the LEFT slightly. He was so far out, he couldn't tell if it was right or left. He thought it was right so he applied left aileron, causing the plane to roll further left. The confusion continued for another second or so. Finally, he had the plane rolled so much, it lost lift and started to fall. When that happend, he reacted by pulling the stick. The plane was nearly inverted at the time. Pulling the stick when inverted puts you in the ground.
The reason I'm so familiar with this scenario is that I've done it and have the medals for it. It looked EXACTLY like that crash. It ain't pretty.
BTW, if there was a chance for him to get out of that situation, it would have been to continue to roll left and apply DOWN elevator (stick) while continuing to roll back to upright. Kinda of counter-intuitive unless you've been there a few times.
OK, I'll shut up now.
