Fuel mixture 50:1 using Stihl HP Ultra
3 blade Ramoser vario prop 25,9 x 18 pitch

1)1st test with original settings turn 1L, turn 1.5H
- Lowest RPM i got is 1100-1200. I can't trim lower because throttle level already reach fully at zero position
-When throttle up fast the transition is not smooth and will cause engine to die. Even with throttle delay 2.7sec the engine will die during transition to high rpm

2) 2nd test with turn 1 1/8 L turn 1.5H
- I can trim the throttle down to 800 -900 Rpm
- Require throttle delay about 2.7sec for smooth transition from low to high without engine dying and its working fine
-Is turn 1 1/8L too rich? You can the amount of oil coming out from the video i shared. Is that normal or too much

Any suggestion or advice from this result would be appreciated.

1 1/8 is not too rich. No worries

the oil coming out of the crankcase gets less from flight to flight. Most of that is the grease that Michael uses during the build process.

I did get the manual but I wish I would have some installations templates.
I'm also looking who has stand-offs for the IL230 LE here in the US.
In order to break in the engine which propeller would you recommend?

Thanks

areopanda can get you some. But I think you can use any other standoffs which are in the lengh you need.

what prop do you want ? 2 blade or 4 blade ?
important is to keep the Rpms low on ground. Engine revs up a lot !

I'm looking to use a 4 Blade prop on the Kolm IL230 LE. (Any advice?)
Now I'm trying to get the muffler + pressure tank system + Metal parts only from the Mounting kit CARF Mustang for IL230-3 V4.
What's better to use with this engine? tank pressure system or Fuelpump?


I have contacted Ploberger and they stated they could sell me just the Metal part as I asked but they told me to contact Aeropanda which I did but didn't get any email reply yet.
I also contacted Carf as they do have the muffler and Mounting Kit on their page but received a call back from them stating that they do not have any interested in selling just the parts or muffler separately due to small profit margin. (Bummer)
Carf should not post those items as accessories if they don't want to sell it.

I have paid someone to make a mock-up or the IL230 LE in 3D (Solidworks) so I will try to 3D print the engine in order to make the alignment/adjustment easy.

Thanks.

I talk to Danny from aeropanda.
he will get you all needed parts for sure.

i prefer pressure tank system.
light weight and never fails.

4 Blade:
Ramoser or Fiala

I have a CARF Mustang with Kolm 150 V4, I cannot make up my mind on which prop to use

I would like to use a 28x14 Biela 4 blade mainly for the look. Would a 30x14 or similar 2 blade be a more sensible option?

i do not want to sacrifice performance over static looks to much!

thanks

I have the older Kolm 150 in mine and Im using a VarioProp 26.6 inch 4 blade adjustable prop. This was recommended by VarioProp. Set to 4600rpm on the ground.

cant really tell a lot about biela. Tried 2 times and wasnt happy with the outcome.

for sure the Fiala are performing really good. 2 blade would be 30/16 for this engine. So maybe the 30/14 biela will fit. Fiala has always to be a size bigger compared to other brands.
maybe 28/14 4 blade Biala would fit !

Important is to take an eye on the rpm. About 4600 on ground is max.

Thanks, sounds good, I will be using rpm telemetry to keep an eye on rpms

I have ordered a couple of Fiala 30x16 👍🏻

perfect. Important is the rpm in flight. Let me know how much you did.
we recommend to stay below 6300 Rpm.
In future the ignition will cut at 6200. One more safety feature we invented.

the single zylinder can handle this rpms, no worries.
if you need more airspeed, just use more pitch on the prop.
