All about Kolm Engines
 
Hello!

In this thread we bring together all informations about running a kolm engine!

My name is Tom and i´m team pilot in europe (sorry for my bad english :rolleyes: ). together with other team pilots and some skilled kolm users all around the world we try to bring some important informatios togehter like prop sizes/RPM´s, temps, baffling and so on.
Feel free to show your kolm-plane, your install-Situation or ask anything you want.

Tom

Wery good Tom👍😊

Hi and thanks for this thread Tom! 👍😁


Carf Spitfire and Kolm 135. The cowling had openings earlier but they are now closed with shorter trumpets. Readjusted quite a bit but works well. Pictures later.


Also a Kolm 150 on the bench with JGM gear for scale propell on a 3m Me 109

Sounds good! can´t wait to see your photos :-)

Hi Tom, great initiative and you are a great spokesperson for Kolm engines. Was great meeting you in Germany this summer at Horizon airmeet and maybe sometime when all the planets align we hope for you guys to be ours guests at Warbirds over Evje in beatuiful Norway :) ..

I am working on my first kolm powered model which is a Carf mustang with the Kolm 150 3 cylinder amazing engine...can't wait to get her finished and up in the air..

Here is Affas Spitfire with the kolm before modification :

Tom,
Thanks for starting this thread. I think it will be a great resource for Kolm users as well as those looking at a Kolm for a future project. I am currently putting together a CARF P51 Galloping Ghost with a KOLM 155 IL two cylinder. It is my first Kolm engine. It seems that CARF designed the Galloping ghost with the Kolm 230 IL 3 cylinder in mind. I have had to move the firewall up about 3 inches as the 155 is a 2 cylinder. I opted to make my own baffling and not purchase the CARF install kit. I believe at this time they only offer the 230 install kit. I pretty much tried to mimic CARF’s baffling by looking at pictures. I will take some pictures of what I have done so far and post them in the next few days.

you are right, Andreas made it all for the 230-3. but sure, an il 155 will also work out very good. Kolm offers a install kit for the stock-Mustang, but i don,t konw if that makes sense. the cowling on GG is modified to make the 230 fit.
Sure you get it done by yourselfe! send us photos so we can take a look at it.

That looks really nice tom.. mine is not that elegant, but im pretty sure it will work ok..

Hey guys, here are a few pics of the firewall and bracing I made for my Galloping ghost. I Used aircraft ply and then laminated the parts in 6 oz carbon fiber. I also applied carbon fiber to the bottom of the cowel before gluing in firewall. I had to move the firewall up 3 inches as to accommodate the Kolm 155 IL 2 cyl. The hardest part will be making the bottom rib piece that goes in between the cylinder heads and bottom of Cowel.

Hey Tom or anyone else, do you guys happen to have a side view of the actual ribb piece that goes between the bottom of the cowel and the engine cylinders? This would be for the Kolm 155 IL 2 cyl going into the CARF P51 mustang. Although I have the Galloping Ghost I am sure the front cowel area is the same on both versions. I would need a trace or outline of the actual part/rib so I could just print it out and duplicate it on a piece of light ply. This piece is very challenging to make from scratch as once the motor is installed there is no room to take any kind of measurements on the bottom where the rib piece goes due to the fact that the engine is right in the way. I have a feeling that this piece would prove to be a nightmare to make with much trial and error. It would save me a ton of time if someone had the dimensions of this piece. I have attached a picture of the rib piece I am referring to. It is the carbon fiber piece on the right hand side. Although this picture shows the piece for a 3 cylinder motor install where as I just have the 155 with the 2 cylinders. Any help would be appreciated. Thanks

Hello Tom
You are Bogner Tom?

Hello Tom,
I am installing a 100 IL long edition and I desperately need the carb extensions you were using on the 109 Fto place the carbs below the case, are these available from Kolm or did you fabricate these yourself? I also have a 120 boxer going into a 1/3 scale Camel. Keep up the great work.

Max, Your Strega is fantastic! really enjoyed the video. Please share more of them if you have.

JonBoy2, please keep the information coming. I'd like to see how the IL-155 project goes.

hey!
The front cowl is not the same. The il230 will not fit in the stock Mustang.

send kolm engines an email. Maybe Michi can send you the part from the install kit and you make it fit like you want.

Here is a preview of my actual project. Took me 2 Years ... soon ready :)

That would be awesome, Tom,....Thank you.

Sadly the pipes i used are not here any more. if you want to build it yourselfe, send an email to Office@kolmengines.com or ask Götz Vogelsang to help you out.

The first run on the Kolm.. big grin on the face.. :)

How do you tune your kolms in these tight cowlings..do you run them a bit lean as the air pressure is likely to be a bit higher in an baffled cowling?

thanks.


Ixtrim 11-16-2017 12:12 AM

Pure Music :-)

After install you make some testruns in the cowling. is everything sounds good.... fly it. if possible, i lift the plane up on full throttle, to take care that H is not to lean and the engine will not die.
but most time on the first flights you will find out that H is to rich. the engine sounds good on ground (about 5000rpm) but is too rich at 6000+. so you will Need 3-4 flight to set it up perfect.
to see if all Zylinders are adjustet the same, check the dirt in the exhaustpipes with you fingers and compare.

My friend Simon wrote a very good description. maybe he will post it here later.

Tom
