Your jet videos are the 'gold' standard and so much better than 99% of the rest.
Thank you!

Totally agree, no stupid background music either.

jvaliensi, Halcyon66,

Thanks for the feedback. I as a flier try to record what I would like to see in a video.

Cheers!

Very nice filming, Rommel. I’m amazed that you can keep the aircraft framed so well in your videos! 👍

Wayne,
Thanks for the kind words. Any advise you can give me on videoing F3S Jet Acrobatics, I am all ears!

Cheers!

Thanks again Rommel! I've only watched this 50 times or so; can't get enough of that sweet turbine scream!

The engines are not supposed to whistle like that and IIRC, it's an indication that the clearance between the engine exhaust and the tailpipe is incorrect. Been too long since I messed with this stuff but it seems like it means that the engine and the pipe are too close together.

Have to get Dave Wilshire or someone more up to speed to comment.

No, it would be too far from the turbine tailcone to start of the parallel exhaust tube.
Ignore any inlet cone and concentrate on the actual gap. On a 260 I would say 1 1/2” (40mm) maximum depending on the pipe diameter the sweet spot is probably 35-38mm.
BUT I think that is airframe inlet design, not turbine gap. It whistles off power, where normally it will whistle adding power. You can hear the turbine acceleration and it sounds normal.

Ah, learn something new everyday. I appreciate you're answering my question even if Chris didn't want to know.... lol

Sorry I misspelled your last name.

Dave is right on the point about the airframe whistling while power off on downlines. As far as the turbine exit / pipe positioning, I followed the aircraft manual's instructions to the letter and confirmed the same dimension with the pipe manufacturer. This airframe's air intakes are positioned back over the wings and right in front of the turbine. This likely is contributing to the "scream" too. I love it!

Thanks Dave! Chris is an architect…so he’s anal when it comes to measurements. I’m pretty sure he got the dimensions correct! 👍

Everyone spells my name wrong, my father used to blow a gasket about it, I’m not fussed and answer to just about any version of my name 😁

it’s really interesting on pipe gaps, turbine manufacturers, pipe manufacturers and kit producers ( who have their own pipes) quite often don’t agree a gap! The way different turbine types produce their power influences the gap and now tailcone designs vary so much in dia and length on turbines with the same thrust it throws a lot of previous ideas out the window…
Back in the day I used to argue about the rear spacing too, BV had a huge difference between the inner and outer pipe at the tail on the Bandit ARF…that reduced thrust…though knowing BV he did it on purpose to stop people flying that airframe too hard 😉

My airplane, I'll say it first: Geez, what crappy ground handling! Discovered after landing that the nose steering arm set screw had slipped. Be sure you've lock-tited and double checked for tightness every threaded screw!

Hi guys, all Aries jets have this sound in the air. It is given by the construction of the airframe. Be very careful and check everything carefully and secure all screws with loctite. My friend's exhaust pipe came loose during the flight. Aries began to burn in the air. It was completely destroyed after the impact. When everything is in order, it flies very nicely. If you want to use 3D acrobatics, I recommend a turbine with a pull of min. 300N. ***winter***

Loctite on pipe, I’m afraid doesn’t do anything..for thing that get lots of heat……what you need is metal lock nut system, either lock washer (different type) or a metal lock nut (not the Fiber one)

You're right, Dan. He wants to combine it according to where the threaded connections are located. ***winter***
