Tamjets TJ120 test flew in Skymaster F-86


Here is the first test flight. I had E-Logger onboard to measurement the efflux, rpm, watts and amps.

TJ120 was using 1915 1Y motor with Castle HV110 on 12s.
4.46kw at 104A.
Efflux 210 mph
RPM 26400K

Man that sounded nice and looked to have good power! Ron your F16 is going to be sweet with that fan. I bet the F22 would go nice on this fan also.

Wow!! Did that ever sound sweet!! I can't wait to get going on this F-16!

Your numbers blow doors on all other dynamax conversions on 12s!

You’re at

4.5 watts 104 amps with 26400 rpm, 210 mhp efflux
With a 2 lbs pound fan with the ESC included!

Take my scorpion at

4.2 watts 107 amps 23,640 rpm, 192 mph efflux
Fan is 1 lbs 14oz without an ESC... so call it 2 lbs 4 oz with ESC

Or compared to the XPS

4.7 watts 115 amps 24425 rpm, 197 mph efflux
And a whopping 3 lbs 6 oz without ESC call it 3 lbs 12 oz with ESC


Your getting 8 mph more efflux, 2000 rpm more, 11 amps less
And the biggest part for me you’re saving 1 lbs 12 oz!!! Over the competition

Tam that's just super impressive... I think that shows just how efficient the right Nue inrunner in this fan can be

Put me down for one for my F-16.... it's going to be off the chart!
And my F-16 should be a pound less with all the bells and whistles
Can you imagine it at a pound less with the unrestricted 120 mm duct
That your F-16 has ...wow...it just gets better and better

Love it bud! The F-86 is next on my list after the 16
And it looks like the 100mm duct isn't hurting you much at all... I know it get pretty narrow at the nose gear but with that performance I don't think it matters

Ron,

the numbers make perfect sense. it is a very efficient motor...and this is not a full size dynamax rotor.

excellent job Tam, runs and sounds great.

well.... He's got less fsa (120mm vs 128). So he's got the efflux advantage, they have the thrust advantage.

Tam - What is the outside diameter of the shroud?

And how much will they retail for?

Hmmmm.... this is getting very interesting... dare I say Tam that I have a few projects that could benefit from some of these...

Do I remember correctly that you were also working on a smaller (110mm) and larger (133mm) diameter version?

Watching with interest

Yeah I need two of the 110's for my A-10. That will sound sweet and cruise at about half throttle or less. Perfect for long flights and scale sound.....(Somewhat for an A-10). I still prefer a turbine's sound and performance, but I love this fans ability. I think Tam should get some kind of engineering excellence award. He develops more stuff in terms of edf than any company I know of over the last year or so. Come on!!!! The TJ-70,TJ-90(5 Blade stator & 7 bladed stator),TJ-100HP,TJ-110,TJ-120..... I would say Tam works too hard!! He doesnt spend enough time with family and himself cause he is always working to make our world in edf even better. Now thats committment!!!!

Exactly! but on the bench. messing aroud until sizes were dialed in and looking at applications, it always seems to get the extra pound or so you alwys needed more motor to take full size loads. so make a pound more take a pound in weight and load. and thts on a bench, then ya gotta find a plane that could feed it. at 20 its like the magic number cause its also a simple equation of 50%motor tube 50% rotor area. Thats why this sabre being the wore case is the bet test, cause this is all installed i a plane with barely a 90mm inlet. real funny thing is this fan is easier to FSA than the TJ100!! go figure!

Where did you get these numbers from? The correct numbers are:

112A at 26,400 RPMs and ~260 MPH efflux (using a 3.375" exhaust).
