Can we get photos of the spinner Installs and details on how the engine is set up to receive the prop and spinner?
also, is there a soft copy of the Kolm users manual in English anyone can send me? Gotz hasn't sent one yet and I'd like to review it this weekend.
obrigado!

When engine is new, you have to check the vales in short periods. run in-10 flights-15 flights-20 flights.... and when season is over :-)
congrats to you sucessful installation Kim.... so who is next ? :-)

I got quite a bit of work done last night, should be starting it this weekend for the first time :-)
In talking to Tom, he brought up a good point about the electric starter. How do you disconnect the lipo when not in use? Or even between flights? Emcotec makes an electronic switch, you can make a manual switch, or just unplug the deans connector, but then we wouldn't be funding the people who make these great products and keeping them in business ;-) I spent $4k on a motor, I'm not gonna scrimp on little bling things.
This thing handles 50 amps and you can use any of the emcotec switches. I'm going to experiment with seeing if a spark switch will turn it on and off, otherwise, I ordered the magnetic hidden switch like I have for the rest of the power system.

Hey Doc!
You are right... this is a problem :-)
so we created a Box, where you can handle this! It is called ISB (ignition start Box).
In this Box included is the kill-switch for ignition and the switch for the starter battery. when your RX is on, the box turns the starter-battery on.
the ignition runs from 30-100 percent. so you can handle a fuel pump also with only one channel.
the box will bei available at vogelsang or you write to me.... price is about 100 euro.

Started up the plane for the first time today. started immediately. vibration at low throttle is severe, so severe that it is not flyable like this. Once past mid throttle, perfectly smooth. Kim, I think you had the exact same problem and it was the hall sensor position?? I will have video uploaded soon. Need to figure this out.
Sound was glorious… :-)
With the three A123's and a 3s lipo behind the cockpit, its gonna take around 2 pounds of weight in the tail. Total weight will be around 49 pounds. How does this sound for those who've built it??
Kim or Tom, any advise??

So without the starter motor you save about 3.5 pounds overall assuming you would then not need an extra battery nor any of the tail weight. I ordered the starter motor too but will bench run the engine first and if it hand starts easily and consistently I'll have to seriously consider removing it. Thanks for the news and data and good luck blazing the trail for the rest of us.

So, bonehead move of the year award belongs to me. Can I still blame lack of sleep on the newborn even though he's sleeping through the night now? I had the throttle and choke servo leads plugged in backwards. ;-) I was wondering why I was hearing servo noise, I had the travel adjusted perfectly on both…. Really surprised it even ran. So, hoping that explains a lot of the roughness. Tom mentioned this might be normal at idle, particularly for a new engine. If thats the case, I might experiment with harder mounts. Or use metal.
Lucky, do not remove that starter. It is too cool to just flip a switch and watch it fire up. I am using a 3000mah 3s pack and after 4-5 starts, and one long run when I didn't have the ignition on, it only took 9% of the pack. And it wasn't even warm when I pulled it.
I know Gary Prince flew a carf corsair at 75 pounds. My carf P-47 had to weigh way more than 50. I think this weight is acceptable. And I think I can get the packs about 8-10" farther back than when I did the rough CG. It will take lead in the tail to balance, but I'm guessing under two pounds.
The sound is awesome, even at idle. It sounds nothing like any of the other planes I have seen first hand. I love the moki sound, this could be as cool, just different.

I bought this laser level for when we move into our new house so I can level cabinets in the shop. It was pretty slick to make sure I put the plywood braces at an even height on each side ;-) I've got the batteries another 6" behind where they were when I did the balance. I could probably even farther back, but then accessing them would be a PIA.

Hello!
Sorry for Late reply, was an the airfield the hole Weekend. By Bf109 Is Gettin better
I watched the video Many times. Believe me, the motor-movement is normal. And why ?
2 reasons:
First because of the crankshaft with 270 degree. That runs like a V-engine. Pro: the pure Sound.... Contra: Vibration AT Low rpm.
Second are the Type of Rubber and how they are installed: if you Have soft One like These, it will be better when the distance between every Rubber is bigger. But in Mustang is no Space for engineplates to seperate the holes more. And of you will use more rubbers, its also better.
But: do not use Steel. Bad for the Model and RC.
My il100 in Bf109 does it Same. And i Have no Problem with that. Why do you Have ? The Most movement you have at exhaust pipes. You Need 5mm Space in each Direction. If you Dont like it, use harder rubbers or Try to fix One more. How many are in the Front ?
Someone asked about My P51 and il150. It have to wait... I got a Pitts S1 from Toni Clark and i did an ez50 in. It's nearly Ready.... And then i Can start the Mustang

Hello!
No the IL150 runs smoother because of the 3 zylinders.....
look at Tomīs Spitfire with IL135. he had a very soft rubbber installation and did about 80 flights per season without any problems. (now they are a bit harder)
Watch in HD an full screen... look at the exhaust pipes!

Mike, the Kolm sounds Superb !
Electric start too, WOW !
Probably just a few tweeks and you'll get her dialed in.
Anyone want to buy a ZDZ 90?????

I don't use rubbermount For the 150. i Build my cooling with Foam
directly to the Zylinders , so its not good when my engine is moving to much around.
The starter Works perfekt. I used 3S lipo And later 2S. What you See in my Video is a start with. 2S. Looks very Real!
It's not easy to Handle alle the cables
And: i use a fuel Pump for the Il150
