yes and better when flying especially at high revs. The bigger the engine the better the sound, so 1/3 is better than 1/4 while 1/2 (like my ENV) is better still.
Thank you for your wonderful explanation of the making of the water jackets, a friend of mine is involved with Bismuth casting and moulding, my Napier Lion water jackets are original mild steel and I had the concerns of corrosion as you had, I went in a different direction than the waterless coolant and now cool the 98 year old engine with lathe "suds" coolant with excellent results.

Thanks Andy, glad you found it interesting. I do hope your suds coolant doesn't turn into a gelatinous mass in the bottom somewhere. Perhaps you can recommend a sol oil that doesn't do this?
I was also concerned about that, after 12 years of running this as coolant all the waterways and cooling system give the same temperatures throughout when checked with the laser thermometer, maybe having the coolant pump at the lowest point in the system has made the difference ?
If you are interested in the build of this engine you can read about it in the RCM&E model aeroplane publication. Sept 23 issue covers the project nearing completion so to get the whole series from the start you would have to obtain back issues to the start of 23,maybe even late 2022. Definitely worth the read!
Wow, it sounds so smooth compared with the later larger capacity machines. Superb work, thank you. A bb crank, so presumably splash lubrication to save weight - not a bad idea for a low torque engine I'd say.
yes it is very smooth. The Company made a point of saying their engines would NOT be reliant on splash. However, as I couldn't be certain how effective the pumped supply would be in the model I fill oil to a level just below the crank sweep and trust that mist will rapidly build up. I also use a little in the fuel, about 50:1 as back up.
As a modeller, I am grateful for sharing a video about such a great technical work, I envy you for these vibrations, smells, sounds and discussions. It is a great technical aesthetic to build and run such a beautiful scaled down engine.
A great technical work!. Since you already have a V 2x4, you can try W 12 (3x4), for example Lorraine Dietrich 12Eb 450hp. I have not heard the sound of a plane motor in the W12 (3x4) layout yet. There are still many interesting and available in aviation museums such engines but asleep. Since you already have a V 2x4, you can try W 12 (3x4), for example Lorraine Dietrich 12Eb 450hp. The truth is, your work is impressive end unique.
Ha! thanks for your kind remarks but this one was quite complicated enough for me. I deliberately chose a pre WW1 example thinking it might be easier than something from mid century like the LD or the Lion. There are indeed many engines asleep, as you say, but most of them lead nowhere, whereas the little ENVs in the hands of young pilots like Sopwith acted as a spur to development that lead to a great industry. Another engine of mine, the Lynx which you may have seen on my channel, was regularly flown by Whittle and (in its lack of power at altitude) _may_ have got him to dream of a turbine engine to get him higher & faster. These are the human connections I find so inspiring.
This is absolute heaven, and wasted on a display stand. Get someone to build an aeroplane round it! With engineering that beautiful, I'd fly in it with confidence. Thank you so much for sharing it with us.
My Mono rotary engine was built specially for a friend's Pup which flew very well with it but so nerve-racking! My particular concern would be that many of the highly stressed parts were not made to the exacting standards required for flight of significant duration. eg the Lynx gears are left unhardened and there are no oil control rings. It would fly all right but for how long? A proper flight-worthy engine would need stricter quality control at every stage, administered by someone other than the builder. So thank you for your confidence but I for one wouldn't let you leave the ground!
@@aerowez Ha, many thanks for that explanation. I think my confidence was founded on the old adage, "If it looks good, it'll fly well", and boy, does your engine look good!
Yet another running masterpiece of a rare engine. I offer great admiration and sincere congratulations for this achievement, as well as gratitude for sharing the video of it taking life.
Spectacular work, magnificent achievement! Building or rebuilding a vintage engine is a satisfying challenge, but building or rebuilding the engine to run is the pinnacle of builder/rebuilder's art. Thank you for your efforts and sharing them here.
