Maybe the smaller can allows the propane to still swirl around to the plug, I know on my old RAM's if the plug wasn't between the 10:00 and 2:00 positions they wouldn't light until the whole damn can was full and then they'd go BANG so freakin loud you thought the engine had blown up. Seen the same issues on most engines. At least that airplane is small enough that starting inverted wouldn't be that difficult anyway

Cool project.

My friend has one too....with a prop though

Are you going to heat protect the tail from the turbine exhaust ?

Henke Torphammar

I appreciate your input and I will be prepared for the first bang, until now my testing have been fine though. I regulate the gas manually as this engine only needs a little bit of gas for about 2-3sec when you are used to it

Henke Torphammar

I found it not needed. I did try the looks with aluminum tape but I don't like it so I removed it again, my earlier testing shows it's not needed with gas and air-blower start.

Front view of the now airstarted Kolibri T25




This is how it mounts in the airplane, a lasercut clamp and a CNC cut former from HAB Electronic.


The engine mount glued in place useing epoxy and what we call white ash as a filler.

do you know whats the dry weight?

im sure you easily go beyond 250mph with all the hard work involve!
keep it up!!!

Henke Torphammar

Dry it will be about 1150grams. ...if all internals will fit haha

What is your thrustline for the turbine since it is above the C/L of the wing and forward of the CG?

Henke Torphammar

I've set it up with the tailcone pointing rearwards About 0°, I'm sure it will not be a problem.

Interesting project. All I can say is you must have very good eyes. Keep up the good work

Henke Torphammar

Thanks! Compared to my old plane pictured in my avatar the Swist have double the wingspan and a bright dayglow paintjob instead of a cloud-white finnish

Henke Torphammar

Installing the electronics would prove to be a challenge. I did strip the ECU and changed the RJ45 connector to a 4pole connector going out the nose cone for easy access. Also the gas post and battery connectors go out the nose cone. Two 350mAh packs, a Jeti 12A BEC and fuelfilter togeater with a solenoid and pump... hm

this did't fit

looks pretty fast.......got any messurements of speed ?

Henke Torphammar

I need to do more testing before I can get a proper top speed reading. It is faster then the Baiojet though the video shows a flyby after gunning it when properly aligned with the runway, so still accelerating when passing the camera. Now I need to find some sort of super human so operate the camcorder

Rock and roll Henke!
Now I have one unemployed Stalker radar...

While awaiting for better weather and a shiny orange front cover for the engine I'll share a pic from the testflight in early march

Would probably be easier to get a normal human to stand further back from the runway!

Henke Torphammar

Yeah, we'll figure a way to get in on the screen

New cowling arrived from Martin Lambert, in this config with air start the little engine capable of almost 7lb of thrust weighs in at only 7.79oz. Quite impressive

Henke Torphammar

The first video from the Kolibri meeting, only a small clip of a launch at 09:00-> and a view of the plane at 11:35->

I throttle up to about 1kg(2lb) of thrust when launching and then give a short burst of full power(7lb) on the vertical until going down again back at maybe 1kg(2lb) of thrust. I hope someone got my full power runs of the Sunday

Launches so easy even at 1.35kg(3lb) fueld up.

More later I guess

Nice video. Good to see people enjoying low cost turbine flying in modest size planes.

Your Swist is nicely dialled in, though it looks like you could do with a bit more power!

i have one of these kits, but it will be a standard prop.
do you also tape the back of the wing to the fuse? with the wing bolts so far forward the rear seems un-supported (?)

Henke Torphammar

As Martin develops the engines continuous I think we will se that in the future. In house multi op CNC and laser welding keeps the engines very well up to date Maybe I will try an Opus with two engines as it's got alot of space in the fuselage for dual electronics setups
