JR 11x to DX18 Transfer

This has probably been mentioned before, but if so I can't find it. Is there any way to transfer models from a JR 11X to a DX18 gen 2? You can save the models to the same SD card but the DX18 just...

I had a similar problem once with my 100 … was caused by a small pinhole in the fuel line where there was a burr at on one of the filter nipples. You could barely detect the leak but the tiny hole...

For the same turbojet engine, the square-law RPM relationship generally holds true for static thrust. Try knocking it down to 110,000 and measure the static thrust with a fish scale ... I think you...

I'm with jctpro - I like my jets a bit overpowered and I wouldn't worry about 16% more thrust on a 210 vs. a 180. I find it pretty easy to enjoy the power in the vertical up direction without...

The original G1 Kingtech's used a Xicoy ECU, which in my experience works fine. I have three G1 Kingtech's and have had one flameout in the air in 200 or 300 flights. That flameout occurred on...

Pressure ratio doesn't have anything to do with thrust - you could have the same pressure ratio on a 22 lb thrust turbine and a 22000 lb thrust turbine. A modern, single stage centrifugal compressor...

Thanks, Jason. That makes sense for the cracking above the gear, but the 2" long section collapsed on the leading edge ... hard to get behind. I guess I could take out a section further back and...

Kingtech has a couple of specific turbine oils they exclude due to observed coking problems, and I think all 2-stroke motorcycle oils. But to the best of my knowledge they do not require you to use...

Since I was going fast, obviously I did pull too hard in the turn and I exceeded the critical angle of attack, no question. However I am fully aware that jets are not good for "yank and...
