My bad...an attempt to get the precaution out to more folks. Thanks for the guidance.

I have deleted all that I could. However, some would not accept the edit. I will leave the one in the Radios and Receivers thread.

I think that's where it should have gone all along. Your situation with your "dead zone" may have been unique to your flying site as my dead zone to mine. I highly doubt that the new 5G network will provide widespread RC radio disturbances everywhere. Perhaps a precautionary warning to your own club members at that site would be more appropriate just as it was for me at my location.
If I have any further comments, I'll take it to the radio thread.

Posting here to reach a more general audience.

My main transmitter is in the shop, but today was such a beautiful day that I drug out my old 2016 vintage birds (and older radio equipment, of course) to get some flying in.

While the radio gear is about 2015/2016, it is FHSS by design.

My question is posed from what I experienced at the flying field today. There is a cell phone tower about 2000 ft west of my flying position (as measured on Google Earth). When I fly west of my ground position, I narrow the distance to about 1,300 ft. One can assume 5G signals are being transmitted. Note: This is the first time I have flown at this location since 5G was turned on.

Twice today when I was west and near the cell tower, I lost control…total no response. The airplane was heading south and in descent from about 400 ft up. Once the airplane got about 100 feet in altitude and further south, control returned. I was able to complete the flight normally. Again, this happened twice and roughly in the same location. So, I decided to stay closer when west of my location and also flew most of the time to the NW, N, and NE of my location for the rest of the afternoon. Staying away from the cell tower prevented any further loss of control events. I flew two different aircraft today, but only one experienced the loss of control event (twice). The other plane…I kept it away from the “bad” area.

Is this a symptom of 5G? Are we going to start seeing loss of control events when flying near cell towers, now? Thoughts/Comments? Have any of you seen this?

All the cross posting is stupid. Now all the responses and information will be scattered and useless because of it.

I just went back and double checked the main wheel OD with the retracts deployed. I couldn't get the calipers far enough in to take into account the slight tire bulge in the center. Well, the tires are exactly 65mm.

[T-CAT]

The OD of one of the main wheels is about 64mm. Call it 65mm and you'll be good.

Thanks for posting pics of the main wheels/tires. It appears that the PJ50 Main tires are the same exact wheel as the Freewing Avanti 80mm EDF jet Nose tire, which are about 65mm in diameter. On the spare parts page of the PJ50 product page on Motion RC's website, the Main tires of the PJ50 is listed as using the Avanti 70mm diameter Main tires, which appears to be incorrect (hopefully this helps them identify the problem and fix it easily on their website). The difference in the Avanti wheels, Mains versus Nose, is also identified by the spokes, since the Main wheels have 8 spokes and the Nose wheel has 6 spokes (like the PJ50 mains).

Thank you so much. I do have a few sets of 65mm so that is awesome. Now I just need to find a pair of AeroStar reversing ESC's.... Come on HK!!!

Check out the HobbyWing. HobbyKing's been out of stock for ages.

For you lucky guys that got the PJ already can you anyone give me the O.D. measurements on the main wheels?

Want to see if any of my electric brakes are going to fit it.

Thanks,

Joe

Glad to hear that the LED was OK.

Would you mind taking a measurement of the Freewing logo on the tail? Want to find out how best to cover it with another graphic. Thanks.

The logo appears to be about 51mm X 13mm.

Just checked. I can only see 9. And one of the outside flashing wingtip lights is already dead. I'll have to see if I have one from an old dead plane or just leave it.

Update on the "dead" wingtip light. It wasn't dead. I had it plugged into the wrong pins on the blue box. Needed a magnifying glass to read the small print on the side of the box. All works well now.

[xviper]

Question for those that have the PJ50T....the product material says that it has 11 LEDs, I can only figure out 9. Three landing lights, four at the wing tips, one up on the tail, and one red strobe between the main gear. Where are the other two?

Got it all done. Encountered a glitch in making the dual ESCs go into reverse thrust. It worked perfectly on the bench before the plane was put together but once I got it together, I could not make both engines go into reverse. Only one engine would go into reverse at a time. When both motors were hooked up, they only went forward. I tried everything I could think of to no avail. Then I decided that when the two ESC signal wires were Y'd together, somehow the reverse signal was either not strong enough or got scrambled. So I went and got a 4-channel smart RX and hooked up only one ESC to it, leaving the other RX as it was. Powered the second RX via the ESC BEC. The first RX has the red wire yanked out and is using the external BEC that came with the PJ. Bound it up, did throttle calibration, hooked both RXs to power and BINGO, it worked like it was supposed to. I didn't even have to do the Avian thrust reverse programming from the new RX as it remembered it from being done with the first RX. The first RX didn't have to be re-bound either. It also remembered.



Looking at the PJ and then the AL-37, I think the AL should have been this size. The PJ is big but not too big.

[MeyerVW]

I don't have the two planes together, but I think it's the same blue that came on the AL-37.

Thank you

I need a close up pic of the color blue that is the striping on the aircraft. Going to make the vertical stab and winglets the same blue color. Can someone get me a close up pic please?
