xviper if you can upload the dx9 file then I can see all the setting that would be great!

[xviper]

xviper would you mind share your transmitter setup with me. I have my rates and slaps all set up on my nx8 but it seems to fly a bit rough with my settings, I would like to compare the two if you don’t mind.

Do you mean my DX9 file? Or pics of my dual rates and expo screens? Please note that I'm running a Spektrum smart RX using AS3X gains ~40%.

I think you're still looking at 3 to 4 weeks.

Should almost be time to see these come out from MotionRC. I redid my decals from Callie. The first ones I made some errors but it will look pretty cool. Its AVA AIR and Ava is my granddaughter. Each window has a pic of her in it.

Congrats XViper and nice flying! Smooth landings….

Would you confirm the throttle setting was mostly mid-throttle after the dirty pass. It sounded like it was.

Most of the flight could easily be done at mid-throttle. It's needs very little to fly. It's quite thrilling to fly something that big that fast, so I flew it higher throttles just to see and hear it go. The dirty pass was probably closer to 1/3 throttle. My landings with the PJ is a lot smoother than with the AL37 for some reason.

xviper outstanding flight, nice touch and go and buttery smooth landing. I have a feeling you'll be flying this one a lot. Looked like you were already more than comfortable with her in just the first flight, imaging what you'll be saying about it after a bunch more! Looks like FW's got another winner!

Thanks, Hugh. To be honest, that video was the 2nd flight. The 1st one was mostly ground testing, range checking and a short trimming flight. The big HRB came down with 50% still in it. I don't video my "maidens" as I always feel I'm too busy doing stuff to it and in case it's bad luck.

Nice xviper

xviper well done! Come on mid March, or maybe earlier.

Nice flight. Really great jet. No snow out there? We got it all here. An "Alberta Clipper" came through....

We've hit a warm spell and only small patches of snow/ice remain in the more shaded areas. Snow could return Monday, Tuesday but only slight chance. It's predicted that we won't get colder than single negative digits overnight for the rest of this month. Next month however, is a little colder for the first week, then quite tolerable. It's almost like winter is nearly over but the weather guys could be screwing with us.

Weather finally cooperated and maidened my PJ this morning. This plane is fantastic! It's stable, fast (faster than most of the jets I have and faster than it has any right to be for its size) and has amazing presence in the air, even in totally stock livery and in spite of the fact that it's not a military jet. Here's an Iphone video ........................ Dual Avian 60A ESCs, dual Spektrum smart RXs, SAFE select, Thrust Reversing, flown on 6000mah, 6s HRB. It doesn't exhibit the tail waggle that the stabilized AL-37 has.

Great flight and I can't wait to get mine. So you were able to get the Avian ESC's to work together without issues. Also, looks like your not far from a full scale airport as I saw a jet taking off from the left side of the runway.

Yes, our field is about 5 miles away from the international airport. That airliner was a WestJet 737, which my AL37 is liveried after. I thought for a split second, I was going to have a mid-air with another RC plane.
The dual thrust reverse was not without a small complication. When trying to run both ESCs on reverse from the same RX, it did not activate. The motors would only go forward. I believe the reverse signal going through a feedback via the "ghost" 7th channel either wasn't strong enough or it got scrambled when split. Putting one of the ESCs/motors on a separate smart RX resolved it. The second RX is an AR410 (4-ch). It has only the throttle lead plugged into it. Programming reverse must be done individually (one RX at a time).

This is a job for Mythbusters.

Knowing RF , I think there is a very good chance it'll interfere especially if you get close to the towers. There's a lot going on there plus side bands and other possible interference. Doesn't take much to play heck with our 500mW/ 1W output signals...

[Gilatrout]

I didn't take GG's post as a precaution, more of a "did this cause the issue" question...

I talked to a couple of retired Sandia Labs engineers that worked on radars and other stuff and they said it was extremely unlikely that 5G would cause interference with rc on 2.4.

The biggest concern is how much the receivers can discriminate frequencies. The better the receiver is at ignoring frequencies not used in RC, the less likely that there could be noise affecting the signal.

Unfortunately these aspects of the technology are black boxes and not generally available to us to know.

So the short answer is for now, 5G is.far enough away from RC frequencies that it is not likely to have an effect on us.
