Default Loss of Signal - Antenna-less Receiver?

I recently changed my receiver to a Spektrum AR630. I was flying without issue for 2 minutes and then I had a loss of signal. The plane didn't respond and went down into a swampy area. Thankfully, I was able to recover the plane, although, I'll have to figure out how to replace the plastic motor mount in a Durafly T-28 Trojan (the motor mount is built into the foam).
Has anyone noticed a loss of signal? I placed the receiver away from the battery and servos. Any help would be greatly appreciated.

Thank you

Have one in an Edge 540, and a 40 sized Telemaster, both electric and zero problems!

I've read that they work great. I was surprised that I had an issue. Perhaps, it was my Spektrum NX8?

I switched to Jeti a little over a year ago, one of their features really opened my eyes to the importance of antenna placement. The Jeti has RX signal reception strength telemetry. I can view reception strength of both antenna’s real time. My last few new airplanes I’ve experienced the reception strength drop below 50% and a quick adjustment of antenna location solved the problem. Not knocking Spektrum, just pointing out that RX location is more critical then we imagine.

Thank you speedracerntrixie! Being able to check signal strength is a nice thing to have. More transmitters should have that as a standard feature. I'll look at the placement again, although I thought I had placed it away from any interference.

I’m sure that you did a good job of placing it away from items within the airplane that can generate electrical noise. However there are usually things within the model that can block/reflect signal. Metal pushrods are one thing that concerns me.

I may try mounting the receiver on the side of the fuselage. Perhaps, that will help.
