I am a moderator on model engines and they use R & D or research and Development. I do know if site in UK but K, Q and P is also some times used.Jokes only, no politics, divisive topics, etc. Posts that violate our rules will be removed without warning. Please do not respond directly to any offensive or inappropriate content, click the report button and let the moderators take care of the issue.
Thanks and Enjoy
Dave
