[@rickymassey9341]

How did u shield all that heat from the foam.

[@janmb]

@@rickymassey9341 The short answer: Air. On any proper turbine installation, regardless of building material, you use a thrust tube that has a single, critical purpose: Wrap the hot exhaust inside several layers of insulating air. If done properly, the foam should never experience any more than ambient temperatures.

Always great to see you two guys produce a video. Jan is so smooth on the sticks, and you as well on the camera Tommy. I stopped flying turbines 10 years ago. Your last two F22 turbine vids have me thinking about it again.

[@RCTommy]

Thank you, John Thomas. I've recently jumped back on the horse with one of Jan's JetCat P20SX installed in my new Freewing Gripen. Still a lot to learn, but flying a real jet again has been a lot of fun. Cheers! 😁

[@janmb]

Thanks - and yeah, you should definitely get back into turbines. A lot of fun - and the technological development has been massive

Great video great flight

[@RCTommy]

Thank you, Billy Wells 😁

[@janmb]

Thanks :D

[@rc-timo]

Hats off 👏 ☝this is how you make enjoyable RC-Videos. Thank you guys👍

[@RCTommy]

Thank you, Timo, much appreciated 😁

[@MrKennard01]

Great video. I really enjoyed watching. Thanks for sharing. Best wishes always.

[@gadget_hack]

The camera passes are the best 👌

[@rcturbinator7855]

Foami fantastic 😀 brilliant simpel everyday turbine machine. I hafto get myself a X-45

[@JustFlyIt09]

Great looking plane and video

[@jetman899]

That's a beautiful field and jet.

[@RCTommy]

Thank you. It took a bit of hard work to make the field as we wanted, but in the end it payed off 😁

[@jacksonrcaviation]

Super cool my friend 😎

[@RCTommy]

Thank you!

[@kendrickh91]

This was beautiful 💪🏿👌🏾

[@thedakotahurley]

It sounds so good!!

[@mikesrcgarage]

What an awesome plane and flight! Does Mibo make a gen 5 EDF A-10 Warthog?

[@JustEnoughRC]

👍🤘👊

[@eqrc7587]

Awesome Brother !!! Get to fly a little longer then 3mins. 😂😃🤣🤣😃😂👍🏻✌🏻🖖🏻

[@RCTommy]

Thank you, brother! From the second video I shot that day, I would recon he got about 6-7 minutes of active air time. Which is pretty darn cool if you ask me. Gotta get me an X45 someday. Cheers! 😁

[@janmb]

Yep, 5 minute timer + enough for a few go-arounds

[@Igbf]

Awesome machine, and very nice editing! Can I make a small suggestion? Your video quality is nice, but youtube bitrate at 1080p is quite lacking (arround 10mbps) despite having 100mbps source material. I would advice to upscale it to 4K before uploading. The quality of course will not improve compared to your source, but the compression on youtube side will be much less aggresive (4K 60fps on youtube is arround 50mbps, which is kinda decent imho)

[@RCTommy]

That is a great suggestion. I will definitely try that for my next video. Thank you for your support! Cheers😁

[@Igbf]

@@RCTommy Thanks to you for the nice content!

[@abosl6an556]

Wooow this very nice 😍🛫 , What is the method of programming the x-45 and where can I find the petrol or the materials to be added to it, and how is the method of programming with the remote control, please help me ❤️😘

[@janmb]

Setting up the transmitter for the X45 is dead easy. Simple teaching sequence (started from the turbine ground support terminal), where you teach the turbine your all stop (trim low), idle (trim high) and full throttle settings.

[@Airguardian]

Long time no see... good to have you back! :D

[@RCTommy]

Thank you, friend! :D

[@PepperPete11]

Great video but man...why not just do a vertical so we can see the power? Instead of always pulling it out at the last second. Or does it not have enough jam to go up? I'm seriously considering an X45 but nobody will just FLY the plane, give a good full speed pass, and pull back on the stick till it can't go any higher. (I'm not an armchair pilot as I fly turbine jets all the time).

[@RCTommy]

There are a few passes where he goes vertical, but it's not that easy to film it from where I stood. The thrust to weight ratio is greater than 1, that's all I can say. Pulling back on the stick until it can't go higher means flying above line of sight in this case. It's not an EDF, this jet will not stop any time soon at such low altitude. That's why😉

[@janmb]

The model has over 1:1 T/W with a full tank. So unlimited vertical from zero speed. Done several takeoffs into vertical climbs. In the end of the day, my eyes and rules limit climbs, not power.

[@10fantic]

I got an x45 powered f22 as well, 32oz tank, 4.25kg wet. with my engine making almost 4.8kg thrust. Will vertical all day long.

[@10fantic]

I also got a video on my channel of the f22 going unlimited vertical I didn’t let up until it was very much at altitude limits.

[@fern6978]

Perfectly powered! How many oz is your tank and what kind of flight times are you getting?

[@janmb]

850 ml, 5-6 minutes

[@fern6978]

@@janmb Awesome man! Much appreciated 🙂

[@janmb]

@@fern6978 No worries 😎 Currently working on a CARF Rebel Hot which will use the same engine

[@RCTommy]

Woot?

[@jimibar12]

w00t !!!

[@andrewsc7304]

Very nice! I love the sound. The x45 is marketed as 4.5Kgs of thrust. Do you have an idea how much is left after installing it in this F-22? Right now I get about 3.8Kgs installed with the 8S Jetfan. Problem is it's too quiet :)

[@RCTommy]

I would say you would get more than enough thrust with an X45 in the F-22. I'm sure the pilot will leave his comment here regarding the details 😀

[@10fantic]

Turbine and EDF thrust don't really compare in the air. EDF efflux is very low, you might get 3.8kg static on test stand but in the air it's thrust degrades considerably. This is opposite of turbine as the air speed increases the engine thrust stays the same and in some cases can increase due to ram air making engine run cooler and provide slightly more power. Exhaust velocity on turbine is approx 1350mph (almost Mach 2) vs EDF between 200-300 MPH, this is the efflux difference.

[@10fantic]

In case you need a better understanding of this, here is a great video to explain it. kzbin.info/www/bejne/sKKwl318mbemf6M

[@andrewsc7304]

@@10fantic Yes, you are right. I knew the dynamic thrust of a turbine would be better, given that it is smaller and spinning much faster. But I didn't expect the difference to be that drastic! Thanks for the numbers.

[@janmb]

Not entirely sure what actual amount of static it might have, then again, it is a very low priority figure anyway. The model hovers with more than 1:1 T/W with full tank. Nuff said. Far more important (to me at least) is, as fantic points out, the massive improvement in efflux, making the model perform far, far better at higher speeds.
