Just got my RT 610 and TR-Q6c transmitter package. During a quick test, TR-Q6c transmitter worked with both Orlit RT 610 and my Yongnuo YN686EX-RT Speedlite in TTL mode. Unfortunately, there was a "pop" and smoke came out near the light bulb area of RT 610. Waiting for Customer Service to provide instruction for return/exchange.
Just want to share the good news on Orlit transmitter compatibility with Yongnuo Speedlite...an unreliability issue with Orlit RT 610.
