Good Red Dragon experience
This is an old thread but I came across it and wanted to put my experience out there. I studied Red Dragon Karate for about five years and am a black belt in the style/system.
I felt the martial arts training I recieved was very good. I did a lot of studio shopping before joining them. In comparison to other studios(in example SKA shotokan, JKA shotokan, San-soo) I felt the training was superior. The instructors take the time to teach you the basics until youv'e mastered them before moving on. I noticed other styles have you learn the moves,even if done incorrectly, and move on then clean up your technique later. I will say though that it depends on what studio you attend.
Yes it is a Mcdojo for sure and some studios are more geared towards adults and some more towards children.
It is also true that there are some very cocky people( Iv'e had my share of dealings with them). I was never like that and I met a lot of great instructors out there.
From my limited time there the style is shotokan attacks, judo throws but with circular movement from a "kung-fu" or natural stance. Judo is part of the curriculum but only more towards sho-dan and above.
In closing my overall experience was a good one. I think for children it's great. For adults it's great but it's not an easy style to learn correctly. You will have to put a lot into it. Iv'e tried to be as unbiased as possible and hope this helps anyone who wanted an insider view on the RDK style.
