Good News

got my stock-Mustang! Is an older version but it was really cheap. Will start building in december.

Will be Voodoo with IL230 !

Not sure if this helps, but Vogelsang lists all their Kolm accessories under "Pricelists and Specials" on the homepage under the masthead.

What color code are you using for the green zink chromate?

Are you going to use the soft engine mounts provided by Kolm?
I think the three cylinder will be smoother than the two cylinder, any info to compare them?

Boy the soft mounts were not good on mine. Shook the **** out of the plane. Switched to hard mounts… I thought it would still send vibration into the fuse… nothing. rock solid. Had a conversation with Goetz about rubber mounts. They seem to be the holy grail with our motors. You have to get the hardness just right for the frequency the motor is oscillating or… bad things happen.

Someone above asked about the zinc color I used, not sure, my buddy mixed it for me. I think I copied it from iflytaillies zinc color they use on their simulated cockpit panels….

Our 150 just arrived so we are going to run it on a stand with soft mounts to see what's going on.

Go to Home Depot and check out Krylon's avocado green spray paint! It's an easy zinc chromate solution, I used it on a Corsair and a P-38 to good effect. I checked it against color swatches from my personal photos of war birds and other sources and it's very good.

Chris, interesting to see if a bench mount simulates a fuselage... Could be better, could be worse. I liked the idea of the soft mount, my plane and the shattered prop didn't.... crazy vibration.

Chris Nicastro

My Feedback: (3)

Right but I'm wondering if the big difference is the two vs three cylinders and if there's inherently less vibration in the three cylinder engine. It will be mounted using the same front and rear mounts as described by Kolm in the P-51 mount kit.
We shall see I guess!
Ordered the prop, Fiala 30x14, as per test sheet.

Hello!

You are right, the 3 zylinder runs MUCH smoother the the 2 zylinder. i had no rubbers in my Spitfire with IL150. no problems all the time....
but in future i will use rubber mounts with all my engines. We test new one , only 10mm , not 20 and a bit harder.
But with IL150 you can use the 20mm , no problem.

I'm currently flying a comp ARF p-51 with Kolm 135 spinning a falcon 30x13 2 blade prop.
She flies really well and sounds even better.
On ground RPM started at 4900 first couple of flights, now getting 5200 with about 10 flights in it.
Can anyone comment on a 4 blade prop for Kolm 135, I would like a more scale look but without sacrificing much or the sound.

Ixtrim

Try Fiala 26/14 or 27/14 (you can shorten it if it is to big). we used 28/14 3Blade with this engine....

Maybe we should start a new thread just for Kolm engine war birds.
I'd like to know what the ideal prop is for the 150 and P-51. The supplied test sheet shows they tested it on the stand with a Fiala 30x14 and 4900/900rpm. So is this a good starting point to fly the P-51?

Ixtrim

Of Course WE can if you want. But here is a lot of information at the moment
maybe Doc wants to rename it ?

The 30/14 is good. After break in you can use 30/16 or a three blade.

Did you hard mount the engine? I'm curious about where and how you installed your batteries, where and how you may have had to add dead weight for CG purposes and what's it weight minus gas? Did you buy the starter and if so how do you have that all wired up? If not, what's your starting procedure?

luckymacy

Let us ta see more pics. I'm already curious why you went the elevator servos cut into the fuse instead of hidden in the elevator stab. You aren't trying to be really scale like a Warbird on this one? In that case, where is your rudder servo going, etc?

DrScoles

My Feedback: (18)

I'd like to know how the CG turned out as well. I had to add a ton of lead in the tail....

Lucky macy
engine is mounted with 4 bolts in the back, no soft mount.
batteries were mounted as far back as my arm could reach.
I only had to add 4onz into the vertical stab. BB mixed with epoxy.
I think it weighs about 44lbs but cannot remember exactly.
I do not have a starter. The engine will fire in less than 3 flips once it gets fuel into the carb.

Mr Scoles
CG was at factory recommendations for first flight but it had no spinner and lighter prop then. I also added an extra independent servo for rudder and tail wheel well in the very back to improve ground handling. So I do not know exactly were the CG is currently but likely slightly tail heavy than factory recommended. This is dry of course.

Hello82

Very cool to see the IL230 in the Carf...will the 3 cylinders, carb and pipes fit without cutting holes?

What 4 blade would you run on this with this bird?

So air baffling would be the same as you did with the 2 cylinder?

thanks

I think this is a IL 150..

There is a scale exhaust in the works for the IL 150. I hope it's done before I install the engine in our build. I don't want to have to patch holes!
The duct kit that's supplied by Kolm has printed parts to split the front intake. I was hoping to see a fiberglass duct running from the rear firewall to the belly radiator exhaust. I'm going to be designing one so if this works it will be offered later I think.

sounds good ...but Tom wrote top of this page"

False Greg, This is a IL230. Same engine as it is in Galloping Ghost , but 3 not 4 Zylinder. 77 cc per zylinder.

So:
The holes under the elevator wasnīt me. i bought the kit as it is, and the hole where already done. for sure i will close it, and build the servos in the elevator as usual :-)

Colling:
I will build it in same way as wil IL135 or 150. will also work (i hope) :-).
The printed cooling part is ok, but i donīt like the split. i will close the little hole (as usual). for sure cooling works better when all the input-air goes trou the engine.
in my spitfire the cooling air comes from carb-side. but the whole in the front is 3x bigger then in mustang, so i think the carbs will suck all the air away, and there will be not enough for cooling the engine. for sure a IL230 needs a lot of air to run....

CG:
that will be a problem .... the engine itselve is 8kg (no ignition and mounting parts). i will build it as much in the back as i can. with a longer prop mount. the engine will fit in fuselage without any cuttings (for sure when il 135 fits, itīs same size, only longer)
i will build all the RC, Batteries and servos in the back. Voodoo has a big Cooling flap , where i can fix all this at the tail wheel.

Prop:
i will test the Ramoser Varioprop. itīs 29.5 zoll 4 Blade and adjustable in pitch up to 30". they use it for Moki 250, so no problem for the Kolm...
First bench test with my brand new engine we took the Menz 32/18 which they use on Moki. it was 4800 rpm.
BUT: this Prop is nearly 1 kg Heavy. so, when i have massive problems with CG, i have to use a normal 2blade Fiala.

Hello82

awesome, thanks Tom...and what size fuel tank? separate lines to carbs?

...more cylinders are all a bit new to me!
