It's the one Rainer liked for his 130 after testing all the brands, plus it comes with 10mm shaft which the others don't. So I only picked it because he recommended it. Now that I know the TP can come with 10mm shaft that will be a consideration too. I'm hopping Par will test with my motor and the TP as well. I worry he might not like me bringing up the jet fan though

My motor has a slightly higher kv. Over 35lbs ( along with the efflux through a 4" exhaust should be available on 22s, at least for 15 to 20 seconds at a time.
What motor are you running?

So the motor I want to use comes with 10mm shaft and a small flat spot. I see Rainer sells this motor without a flat but he doesn't have the 56114 size. Does anyone see a problem with using this motor with a flat spot on the shaft ?

Mark it will be fine. Done it many times with collet type mounts and motors with flats. It will generally fit far enough behind the flat that it will still be on round shaft anyways. Even if not it will be ok.

Yea I was hoping with a gigantic 10mm shaft it would have enough meat to be fine.

Never had a issue with this either, even on shafts that have a flat almost all the way in to the front bearing.

Well i got my fan from turbinesrc. Ordered on Saturday and it's here on Wednesday. I'm waiting for my motor to get here and then I will see if Par is willing to test it.

I got the motor in and installed it on the fan. The total weight is 1630g for motor and fan.

So the ID is 130mm and the od of the motor tube is 60mm. What's my exit size on the thrust tube? I want to play with chocking it down.

If I did the math right, roughly 115.5 mm is 100%. 90% would be roughly 110mm and 95% would be roughly 112.5mm.
I would think 111-112 would be a good starting point. Did Rainer give a recommendation?

No he doesn't. There's very little info for this fan on his website. I hope he sees this thread has come back to life and answers some questions.

I can confirm your math:
100%=115.33
95%=112.41
90%=109.41
