Scale Furai - Scale 20B Nitro Engine
#54
After taking the engine apart twice, going through 3 glow plugs and resurfacing the housings...SUCCESS!!!
I will post a video tonight of the engine running for two ~20 second intervals! I need to work on tuning, so it will hold idle. It has little vibration and sounds great running!

Here is the promised video...hopefully have a full length video next week after tuning. Anyone with nitro experience that wants to offer advice on tuning, I will gladly take it.
Here are some pictures of the final engine in my album.

the thought never crossed my mind, if I could find a machine shop that would do CNC for a reasonable price it is a possibility for small runs (I can buy the rotor and rotor housing premade already.
I'm not a full time machinist (new hobby of mine) and have to remake a lot of parts due to stupid errors, so for me to mass produce by hand would cost a lot due to scrapped parts. The e-shaft took me 5 attempts to finally get right .
Just a rough guess would put the price ~$1300 or so (mostly machine shop fees and OS Engine parts). For a new rotor and rotor housing it is $240 and you need two, so the kit would already be at $580 for existing OS Engines parts.
Here is a price page for some of the OS Wankel Parts
I could look into producing the custom parts for sale and leaving the OS Engine parts up to the consumer as well as a full kit? I would not even be looking for a big profit because I enjoy this type of work. I wonder if they would sell at that price?
Thanks again everyone I'll think this one over.

awesome man, that woudl be many time easier than trying to make a model from scratch! I know once this is tuned I will want to tag that extra rotor onto the existing design. I do have the materials necessary...

thanks everyone, I appreciate it a lot!
I was talking about production a few posts before, but for pretty much just a SWAG (scientific wild *** guess) I would put it around $1300-$1500. This would probably result is very little interest. If I could find a reasonably priced machine shop I would have no problem producing them for those interested.
Each of the OS engines have a displacement of 4.97cc so for the two of them it would be 9.94cc.
Could that make it a 10X, 1X or .1X? It would be nice to have a name for it.
