He’ll figure it out eventually

That's exactly what I was thinking. I avoid sitting in seats in aircraft in line with the props. I saw what happened when a P3 Orion landed with gear up. The surfboard-size blades went right through the fuselage. Luckily no one was injured.

I know, right. I thought this was a well known discipline in the modeling world. Some people don't get that memo, I suppose.

That's so true!Safety first!Hi from France!

Plane of rotation

Line controlled combat wings!! Clipping the crep tail and keep inside the circle ... That was the days, could have the whole thing, airplane, toolbox, petrol, etc. on a bycicle ... at last when I got out of RC, that was with trailer hook on your car (even bought car that were allowed to tow so and so much) and dedicated trailer for planes, mini work bench, shelfs and elastik hangings for wing section, put in form welded bubble plast 'pockets' .. the real avangarde was with generator and all kind of minitools, Dremmels, drills, grinder, ....

I still have a Webra 1,5cc...

How do you know what rpm it's turning at? You can't spin the prop too fast or the tips will go supersonic and create damaging shock waves.

@@dieselyeti lets take 300mm prop, and you need to spin it around 21500rpm to get supersonic tip speed. 900mm and you are around 7200rpm The tip speed on small scale engines is very rarely the issue. But turning that thing 7200rpm shouldn’t be an issue, but its going to sound like 14krpm for it being 2 stroke. Gearing down the prop will take care of the speed issue but not the rpm sound scale for a V12 sounding warbird.

It sounds better than I expected. But I do agree with you that Radials sound best.

Because the Detroit Diesel was a 2 stroke too. The -71 "Screaming Jimmy" From 1 to 6 inline cyl. at the start marked with same no. in front of the '-71' indicating cyl. ex. 1-71, 2-71, and on Later a -51, the -53 came as compact engines. The last was the -92 in V6, V8, V12, V16. As I know. the no. after the slash indicated cubic inch per cylinder? and they were smart designed .. in the inline series, the parts in one cylinder fitted all same series engines .. 1, 2, 3, etc. cyl. didnt matter And the inline was modular like putting 2 or 4 together in a pack for marine and stationary use. The 'X'V-92 had the same parts fitting and modular principle like two V12 or V16 together. They could take some rpm's .. between 2.000 rpms and 2500 rpm to deliver full power .. and had to, if they had to work, but work they could. And the truck driver had to 'stir the stew' to keep rpm's up. A real engineering marble!!

@@SCS10000 I worked for a machine tool company and they bought a GMC Astro with a V8; I learned to drive this tractor to get my CDL which I did. Yes, I recall stirring the 'stew' as well as the two-speed axle.

@@SCS10000 Can you elaborate on the technical questions I asked about your engine?

Hi Gary, Go to our new KZfaq channel. PhiltechV12engines We have just uploaded a couple of new videos. The engine has reached the final Prototype stage and will be available early 2023.
