My Engine Running.

Post  MauricioB on Sat Oct 07, 2017 12:59 am

Many of us enjoy seeing and hearing our engines running, so I propose to generate this post among all members of CEF, showing different engines, it could be in a bench or bench, or in the model itself, specifying data of the photo, for example:
.engine brand and type
.rpm
.fuel oil
.type and size of the propeller
.others

your contribution will bring a lot of valuable data to this forum! Wink

Most folks take cell phones where ever they go more so than a watch these days
the app is very handy. The trick is to set the rpm range close to the actual, since
we can see this engine runs in the 13k range I set the meter to 15k max rpm
by doing so you get finer resolution on the readings, here is the result. The
program has many presets to suit your engine type and rpm up to 50,000 rpm
much better than the 21k vibration gauge all the same it too was awesome sauce
for it's day!

The resolution accuracy is within 60 rpm with a single mic smart phone when the
rpm range is set correctly.

Hey man! I never knew that you tested that muffler I sent you.. and with the pressure-line! Thumbs Up When was that? It seemed to feed fuel from that wedge pretty well.. and cool that you moved the mount around to prove it. Was it tough to start initially? It can be tricky; priming the exhaust through those muffler-pipes.. I assume that they were the wide-open pipe-sets? LOvE the speed-contest vid! Man.. that baby was SCREAMIN'!!!!!!!!

engine behavior

Post  MauricioB on Sat Oct 14, 2017 8:39 am


beautiful bonnet or cowl, which gives a great look to the model!

Watching the engine running, from minute 0.23, the engine goes on a low let's say, but that's not normal.
Sometimes it has happened to me that when I start a engine with valve of cane that work, put in a march say "rare". This is due to excess fuel, is it due to a problem between the valve retainer and the valve itself? or exactly what happens to make it work that way ?? Huh...

It looks like engine goes too rich and only rocks back and forth, i.e. it never goes through TDC.

I have a few cox engine videos on youtube, guess I'll share one here, the Queen Bee with an RJL diesel head;

Not a cox engine but I think this would be nice! Meet my ASP FT160AR four stroke twin cylinder. This is one of it's break-in runs! Prop is a 16x8 APC.

Ouch, better be careful with the prop and your finger there!!!  lol!

The Norvel spring starters will fit, I twist the end and make a mating hole in the engine mount (instead of the engine lug like Norvel engines have);


Here is short bench run of the Cox .05RC;

Eric, you're an IDOL! ... even the people who accompany you are surprised at your dominion! ... I like how you fly and I'm surprised by your incredible handling, that model looks like a demon and you always have control, that's why I say: you are a genius friend!
