Woooohoo! Rumor has it Brad just finished the testing of his GP61 (#002) on RE2 and Smooth!! Hopefully numbers will be posted soon!

He's dropping me off the stand tomorrow AM along with my 61 (#003) and my 123 (#002)... I'll be putting the 123 through a battery of tests on mufflers, RE2, Smooth and ES pipes this weekend before it gets mounted. We'll post the comparative testing of the EME120, DA120 and 3W110CS

Exciting times!

why only testing using tuned pipes and not canisters or standard exhausts also? i dont find this info much help when it does not coincide with what many of us use.

rpm tests between one engine and another is pretty meaningless as you've shown yourself when trying a 3w on a small prop and then a bigger one. thrust is more value along with rpm figures to determine where the power is made , there could be a significant decline in thrust after xx rpm or max thrust could be produced lower down to many other brands ideally suiting certain styles of flying or specific air frames not only 3d. without this info its only a number and nothing behind it. i dont want to appear that your efforts are not welcome , they certainly are, but there has to be more than prop speed numbers on a test bench to make a worth while conclusion. prop testing should cover a range within an engines capability to show the weak and strongest output and at what point that is produced, practical or impractical. max prop size at max rpm may not be to the requirments of a user if he has no need for that performance criteria. i wouldnt want to nor could i fly an engine that spun a large prop at 7000 where its best power was made. the prop rip alone would guarantee me being banned from any club here. much rather have an engine that harmonised prop speed with thrust output

Any one know the site address to track your engine. Fergie was nice enough to send the number, but no web site address to check it. Not all that helpful.

I didn't do any test bench running just bolted the motor in a Pilot Edge that had a DA in it. What I can say is the motor is very smoooooth! I am getting about the same RPM as the DA 120 with the same prop but better transition and almost vibration free airframe. I don't know how to explain it, but the plane seems to have more jump right out of a hover than my DA 120 did. I am very impressed with the engine so far. More flying tonight and tomorrow!!!

I just removed the MVVS TP from my 58 due to too much power causing cooling issues. If the multi-stage SP is indeed that smooth, I need to order at least one.
The Plane Bender Smooth pipe is easier to tune and does feel better than the RE2.
Here is what I got today.

After i was done, I retarded the timing a couple of degrees. That made a big difference.
Low end was smoother, idle was smoother and the transition was smoother and more linear.

You are absolutely correct. We can only test what we can test. We work full time like everyone else. Have familys and kids.
So until the engine manufacturers start paying us to build the rig required and spend the time doing all the torque and thrust testing. We do what we can do. Share what we do find and put it into a format most people can use to work from. They can take what we have found and build on it.
What we do is not the end all be all.

But if you say we are wasting your time and its useless info.

No problem......... I don't need to share any more

Happy Flying

And I'm sorry.
I forgot the stock muffler at home. So I don't have a base line numbers for guys to compare their motors against.
So again, its all useless info

Don't let one person destroy your findings for the rest of us. It is always fun to see what different props and pipes do. Yes, it all changes in the air and what each person likes is different. That's all part of the fun. Thanks for showing the numbers for us!

Cheers
