So happy that your cat is OK.

[@PetrincicBrosRC]

Me too my friend.

[@neilmackinnon3371]

Excellent result Robert, the true engineer is never happy until he knows why something is not working. And I'm glad you cat is OK.

[@PetrincicBrosRC]

Thanks my friend. And like you said, some extra thrust couldnt hurt here.

[@ual737ret]

Good job figuring out why the thrust wasn’t up to speed. Outlet area for the exhaust makes the difference. You have taught me something again.

[@genlanda]

Captain Robert you are the expertengineer of EDF:s! Good thinking. Big salute from the north of Sweden

[@PetrincicBrosRC]

Thanks my friend for such kind words. Lets hope for good flight now.

[@iriquiosgunship]

I learn something new every day by watching your channel. Thank you for such am expert skills, experience and infos.

[@thomaseubanks7263]

Not bad, Captain Robert. You are getting better. The cause of the thrust reduction has to do with the exhaust splitter. Due to it being a 2 outlet exhaust, efficiency drops off radically. What you have done is to super pack the air in the outlets thus increasing thrust. You can improve thrust even more by modding the exhaust splitter, maybe increase by .3 or so more. Went back and checked my maiden video, and you are right, I need 30 feet of smooth surface. Good job, Captain Robert! She will scream in the air!

[@PetrincicBrosRC]

Thanks my friend for kind words. I was really thinking hard here how to get at least a little more thrust. It couldnt hurt ;-) I will come and check yours. Cheers.

[@BikersGarage101]

Nothing like sipping coffee in the morning and watching captain Robert and Captain Balz... excellent! The Freewing saga continues.

I learnt from this video. Think I must cut a cheat hole in my F9F Panther. It flies well but takes a bit of time to get going too. I ended up removing the wheels and just hand launch it. Flies well and sounds good. Only get 5 minutes from 1300mah batt but it cooks the battery. No space for a larger battery. Salute.

[@mikeflight9]

Well done Pilot Robert. You got it correct. Not enough air getting to the EDF and your reduction of the exhaust makes for a better takeoff. That is a big difference in thrust from the original so it just goes to show that we should check for proper air intake if we have a thrust problem. :D Oh, poor little cat. "but that's not our cat" Oh well. LMAO.

[@PetrincicBrosRC]

I really hope for good flight now my friend. Some extra thrust could never hurt ;-)

[@MoiraOBrien]

I would have loved to see the effect of the extra air intake with the original ESC to see if the ESC actually made any significant difference.

[@PetrincicBrosRC]

I dont know about ESC my friend, but 2300kv EDF does come with 80A ESC. The point here was not in ESC. It is OK for 2150kv motor. I got arround 300gr. of difference becouse of high speed EDF unit. But for that one 60A is not enough. Even if you buy combo set on Freewing they give 80A ESC with 2150kv motor.

[@CradyLab]

The Pitts looks gorgeous! I was wondering what those red & white stripes were in the back or your truck 😁

[@darkofc]

Now, that is some proper science based on experience - great job Pilot Robert !! No question that this baby will fly like homesick angel now! Although you are always in rush (understandable - day job first) - you actually pay attention to details and don't like to settle with half solutions - that is characteristic of very good modeler - congrats again !! P.S. May I have suggestion for one more experiment - test the thrust on Hawk with adapter (pre-connector) - and without - batt. and ESC with just one connection. I wonder how many mAmp-s is going there? (and of course grams of thrust that you need at the end of field, where that tall straw is growing and waiting just for you) ;-)

Also keep in mind that the Yak 130 has a bifurcated duct (one into two) and the BAE has only the one exhaust duct. That makes a difference in the thrust also.

That's just true passion, mate! Try and tell a terrier to take it easy...

[@CradyLab]

I salute your efforts Pilot Robert! I am curious about the space between the exit side of the fan and the point where the exhaust splits out to the two tailpipes. If there is a flat spot between the tailpipes facing the rear of the fan it will create turbulence that will severely limit thrust (like blowing against a flat wall with two holes in it). If that's case you'll need to create a more undisturbed (laminar) path for the air between the fan and the tailpipes by fabricating a diverter -- something like the nose of the old MiG-15 but placed behind the fan output so that the path of the air is gently split on its way out the two tailpipes

[@PetrincicBrosRC]

Good thinking my friend. I was checking that surface and it looks pretty good to me. Not much resistance there.

[@CradyLab]

@@PetrincicBrosRC Well that's frustrating. I was really hoping your thrust issue was a problem with turbulent air between the fan and the tailpipes 😕 On the upside your clever cheater hole may be the solution to finally get this pretty bird in the air! 👍🤞😀

[@flyingark173]

Awesome video, looking forward to the maiden. I am just very curious about one thing...you mentioned at the beginning of this video that the Yak has a 2150 kv motor and the info from Freewing/Motion RC says that the motor is a 2850 kv motor in that plane, is the manual inaccurate? Also, again just curious, did you ever test the thrust with the stock EDF and a 4s battery?

[@PetrincicBrosRC]

Thanks my friend. The EDFs motor was 2150kv and with 4S I got only 800gr. of thrust. If the motor was 2850 then I would have even better thrust. But for that one even 80A wouldnt be enough for 6S setup.

Hi Capt. Robert, i am in trouble about which one to buy: Yak130 or Hawk T1? both planes are rated well, but seems the yak has some issue. Since i am not a wizard of the EDF, i rely on stock so which would you choose? Cheers again from the Belpaese :) PS: i will come and visit you at your airfield when coming to Croatia next summer :) and bring with me one of those beauties to fly together. What a scoop on YT: first formation flight!!!

[@fredmdbud]

Have you checked the stator blades in the duct, which straightens out the air blown by the fan (efflux) for maximum momentum of the air mass - there are different orientations for clockwise and counter-clockwise rotations. Using a mismatched counter-clockwise duct/clockwise will cause thrust to suffer. The absence of a duct lip also has an effect when the fan blades are near-flush with the lip of the duct - air turbulence near the fan blades disrupts the boundary layer over them, killing lift (the fan blades are essentially rotating wings).
