All-New Freewing PJ50 Twin 70mm EDF Jet - Official Thread

[JLambCWU]

Freewing PJ-50 First flight and impressions from Joe Kirton. Joe is president of the Remote Possibilities flying club in beautiful St George UT.

This is a cool idea only if they had a 60 amp one.

I'm sure in time, it'll come along. As has been already mentioned, this dual 40A is out of their latest V2 64mm A-10

It's basically two ESCs stacked one on top of another but with one BEC. If a 60A did come along, it would possibly be too thick to go into the space where the ESCs live in the PJ. Foam would have to be removed.

Did some testing and then did the swap to the Avian ESCs this morning. Here are some pictures .....................................

Here's what it all looks like when yanked out of the plane:


Close up comparing the sizes of the ESCs:


Avians installed in the plane:


I plugged everything in and it all works like a charm. Thrust reverse works as was expected. However, as mentioned before, power lead from one of the ESCs had to be removed. With both hooked up, both ESCs just kept beeping and couldn't initialize (these things are too smart). I did the throttle calibration and programmed reverse one ESC at a time. When done, disabled one power lead, hooked it all together and BINGO! Now, I just need to make up my own Y to tie the two ESC battery cables together. I'll use the stock wires to make it. Rather than cutting off the IC5s, I'll solder a couple of EC5s to plug into the ICs. A couple of extensions for the throttle cables was all that was needed, using the stock Y. I think this thing is going to be a blast with thrust reverse.

Next: Minwax treatment.

On an amusing note, just on the heels of Horizon telling me that twin reversing wasn't possible despite my evidence to the contrary, they announced a v2 64mm A10 with reversing. Knuckleheads.

I suspect you will need to extend the wires on your Avians. Almost certainly the wires to the battery,.

No kidding! They shot themselves in the foot with that one.
I haven’t unraveled all the wiring in the tail section. I’m hoping they are Y extensions but if not, I may just cut the existing wires and use them as extensions for the Avians.

Not yet. Tonite, I was going to first test the stock fans and ESCs just to make sure they work. Then I'll see about installing the Avian's and getting the reverse working. Other things got me distracted and the evening is disappearing fast. Maybe tomorrow, I'll start that phase of the build.

xviper I have ordered the Avain 60 amp esc as well. Have you had a chance to put them in your plane yet? I am just waiting on my plane to come from rc castle its been shipped and just waiting. Just wondering if any modifications are needed to install the esc?

Is it march yet?

I'm thinkin I would keep it semi-simple and do a copy of The Kingsman jet.

RE: The 3 light leads from the wing...... Just happened to have a 2-wire light extension cable from a dead plane. Now, I can make the connections from the wing to the blue box in one motion. Tape the 3 plugs from the wing together. Tape the 3 plugs from the blue box together. Equals ONE triple connector. The 2 ribbon cables from the wing and the triple light plugs will be zip tied together so only need to fish one thing from the wing. This now becomes far easier to assemble this plane at the field than it ever was for the AL-37 (requires 5 connections per side = X10 vs X3).

Thanks for the work around on that. Quick assembly/disassembly at the field is critical for me.

This would b my choice of scheme if i could afford one right now,,

Finally got to see the BH "Gulfstream" in person and was tasked with doing the photography and video for her website. More in the "What did you Fly Today" thread, but this airframe is definitely a winner. Specs very similar to the FW PJ50 so expect that one to fly just as well. Super stable at incredibly low speed (35% throttle) and plenty of guts to get up and go. While this, like the AL37, isn't exactly my "cup of tea", I can still appreciate a well thought out and manufactured model. I suspect these will sell incredibly well to a large audience and think that after you get your "Gulfstream" (or whatever they're called), it will soon become a favorite. I'm definitely an MRC kind of guy, and never thought I'd say this about the Pj50, but just may have to get one myself. Definitely can't wait to see some of the incredible re-paints that no doubt will be coming in the next couple years like we saw with the AL-37. 7 minutes on a SMC 5300 and over 10 on a SMC 6200. Sweet! I'm positive those of you with a FW PJ50 in your future will absolutely love it!!!

I like that idea. Simple

I was planning on trying to find a 6 wire connector. This is so much better

I've bought a few braces from him, here's his email. And his email is on his advert in the for sale section so hopefully no foul.

OK, perhaps Twowingtj can let him know some other way. I've sent a PM to Wildvortex already with pics and measurements.
I've never had email notification of PMs or of new posts to subscribed threads. When I come to this forum, I immediately see at the top that I have "messages" and click on it. That tells me that I have either PM or new replies to subscribed threads. I don't know if that works for him.

[GliderGuy]

I could take a picture of the nose gear deployed, along with some measurements and PM them to him. He can ask for additional measurements if he needs them.

xviper Thanks!

[xviper]

xviper Good catch on the wing board connections. I like the simplicity of your idea for the light connections as well.

Would you be willing to work with Wildvortex and provide him with some measurements from your plane so he can design and make 3D printed nose gear braces for the PJ50T? I've used several of them on different birds. They really save a lot of stress on the nose retract when flying from grass. Hopefully, with your help, we can have some available when these birds hit the US warehouse. Thanks. See this thread:
