Try a 22x8 two bladed prop for tuning. When you can get 6700 on that, change to the four blade and retune.

I ran my engine yesterday. I had a 22X10 at 6000 rpm my Buddy spins the same prop at 6800 on a DA-50. Is that a problem?
Also I encountered a lot of glitching and discovered the plug caps might have gotten loose. Due to the round Kelo exhaust the caps cant be installed in the correct orientation to have the wire locks to hold them secure on the plug. I'm thinking of safety wire or zip ties to hold then together.

I'm using a 22x10 on mine and I get similar RPM numbers. Yanks my 21 lb TF P47 around just fine. I've also got the Keleo ring and I agree the plug caps can be a pain, but you can get them on correctly if you play with them enough. I think I've got a couple of them kinda tucked down in the fins. My ignition is located just above the engine so I have a lot of slack in the wire to work with.

You really think is all about the prop?

I can' tu get access to a prop of this size this week.

140f is too cold. You should get #1 up to more like 200f (93c). But I would still use a 2 blade (22-10) for tuning. That will put you in line with saitos break in and tuning protocol If you are still in the first 2 gallons.

Hi,

I just try the 22x10 result 3500 rpm again max.


Any clue what can be wrong?


Thanks

I had to turn my low speed needle down to 4.5 to 5 for the best throttle response and temperature balance. Have the throttle closed when you zero the needle.

all 3 plug wires secure? All 3 plugs good? Lipo (runs better with higher voltage) ignition battery charged?

Battery is a duralite lifepo fully charge

Plug can't be pull out by hand except if I squeeze the locking wire

If I lean the slow needle to start up the engine I must advance more the throttle and at 3300-3500 rpm the engine cut momentarily and run again

Some things to consider:

First -- are all cylinders firing? A laser temp gun is a must have tool for tuning this engine -- in my opinion.

Second -- the needles of the Saito carb are strange. I found when tuning mine that the low needle controlled the mixture right up to the last little bit of throttle movement, then the high speed mixture kicked in. Meaning it was easy to get a steady RPM increase as the throttle was advanced, and then at full it would start to stumble because it was too rich.

If you have access to the fuel feed line the old, but reliable, "pinch test" for both the low and high can be used to test the mixture. If you get an RPM increase you may be too rich, you want a little increase, and if it dies when you pinch you are too lean. This is applicable to both the low and high, but on this engine high means "full throttle".

On full throttle rpm drop sometime to 2700 rpm and go back to 3300 rpm. I did try to lean it from Hi and Low needle but nothing change. Hi also try seperatly to increase fuel on both needle and nothing change also.

Engine have use about 3 liters 15:1 to 20:1 mix.

Hi is at 2 to 2.5 turn

Low is at 6.5 turn

Prop is a 19x8 4 blade

top cylindre temp

1= 140f
2= 95f
3=90f


Thanks for your help
You are only getting 3300rpm because # 1 cylinder is the only cylinder firing, this is due to your needle settings, they are set far to rich. A rich needle setting is also indicated by all 3 cylinders with such low temperatures.

Maybe one cylinder is not firing? My engine has to warm up for a long time until all cylinders start firing correctly.
Check that a valve isn't stuck open.
At idle the low speed needle should be set as lean as possible while allowing the engine to rev up quickly.
At full throttle the high speed needle should be as rich as possible while allowing full power/rpm.

Check to make sure your ignition wires are on the proper cylinder. I've read where a couple guys miss-identified the cylinders. The correct position is from the pilots point of view, IOW from behind the engine, not facing the prop.

Those temps you gave us are low, but as you're from QC I presume you meant degrees in C, not F. Still, it looks to me like you're running on one cylinder. That's exactly what would happen if the firing order was out of whack.

Betcha a dollar that's the problem!

I was thinking the same thing... certainly worth a quick check!

Had a friend break the master rod in his engine by trying to get it to rev up, he was also getting around 6,000 rpm and went to a smaller prop, bad move. Don't expect the 60cc to fly a TF 47 like a DA 60 or even a 50. Best speed measured by radar gun with the Saito 60 was around 75-80, with a g-62 same plane 108.

I agree mine turns about 6000 with a 22x10.It's not as fast as my DLE55 powered warbirds,but the sound is worth it.

Mine broke the master rod running a 22X10 turning 6000

I am concerned every time I fly it,but so far so good....I know many have had this problem. We have a club member that flies the single cylinder 21cc and he has had two cylinders crack.

Mine fg60 with 22x10 prop gets around 6000rpm and after 8-10 liters still run like a clock.

I am having no luck getting the spektrum telemetry TM1000 unit to read from the rpm connection. Has anybody managed to get an RPM telemetry setup to work with these saito radials?

Well, I am now a card carrying member of the "Duh" club. I wasn't getting near the rpm's that is listed. I even flew the darned P-47 at 4300 max rpm... fortunately it was a stable aircraft.. barely flew it.. so after lots of reading and studying and scratching my head and the plane gathering dust in the hanger...I finally noticed that I was reading the diagram of the ignition wires backwards... ummm "from the pilot's view" . I was looking at it from the front of the plane. I had #2 and # 3 spark plug wires reversed... Gee... also I found out my LiFe battery I had used for ignition had failed.. not enough juice... Wow what is that sound? lol now my engine sounds like the ones in all the you tube videos you guys have posted.. I do have a question about the ignition battery. I bought a new one 2S 45C 1300... would that be sufficient to run the ignition? I haven't read where it gives the specs on the lipo just says 2S... thanks again for all of your experience and willingness to share with us

With a 4minute warmup to get #1 up to 200f, and 10 minute flights, i recharge about 340mah per run for the ignition batt. It is a 2000mah 2s life.
I also run a pair of 1300mah 2s life batts with voltage regulators and schotkie diodes. They get about 170mah recharge each per flight.
this setup is in a 30% yak and i fly acrobatic and pattern style. It turns 6700rpm static.
