Default Freewing Vulcan 4S 70mm EDF Sport Jet - PNP

I have The Freewing Vulcan 4S 70 mm sport jet and have been enjoying it since 8/3/2022. I now have 300 flights and I am noticing a loss of speed??? I fly on 1" manicured crab grass and right now it's growing fast and the 2" wheels make it tougher to get airborne.
However, I also notice a reduction of speed in the air. I have flown on 6 different batteries( 4S 4000 & 5000) and there doesn't seem to make a difference. I removed and cleaned the EDF assembly on my two jets and the other one, a Habu, flew much better. No change in the Vulcan and it was originally much faster than the Habu??
I'm wondering if it could be the Motor of ESC???
Any Suggestions?
