Tristan, Hello. This may get you going. Lots of models to choose from but there is a boxer listed in there.

There is a 120cc boxer available through this link (metric dimensions, methanol fuel, glow ignition). I purchased his plans for another engine & they are quite complete - fully dimensioned 2D drawings (originated from made from 3D model) c/w parts listings etc. I haven't seen videos of that particular engine running but I also haven't specifically looked either. A lot of his engines share similar attributes in terms of timing, compression, carburation etc. so I would think high confidence of being a good runner.

I ended up working on a similar displacement 5-cyl radial from a different designer (Ohrndorf), But I compared the plans & details between them quite closely. At least from that perspective I would have high confidence of the Jung being a decent runner. Attaching construction link below for Modelltechnik 7-cyl radial, its also mentioned on his website album page. I bought the plans for his V6 as a prospective next project. Its an interesting design, built-up crankshaft, cog timing belt for cams, twin carbs. I like the looks of the V8 too, only 2 more cylinders LOL. (ps, I have so affiliation with the designer, just personal opinions thus far)

WT engines does a flat 4. Their plans are good. I built the single cylinder version ( as my profile photo) and I think they share similar details

I built the flat four some 8 years ago, excellent engine, very good plans.
My version was built using METRIC system, bolt taps etc, also the use of a Small CNC machine will help tons in making some of the pieces.. running on RC - Nitro fuel, I used a system from Sullivan to drive the four plugs and works great.

jquevedo, I for one would like to see some pictures of your flat 4 engine if you care to post them one day (completed and/or construction, whatever you care to share).

There is also engineman.de he has recently released plans for a flat 4, i have some of his other plans and they are also very well detailed with accompanying instructions. All in metric, hope this helps.
