Yes, there is HUGE crossover among glow/gas guys. I myself am a former glow guy that now flies electric, glow & even gas . Most of the glow guys I know do both now. We have some good activity in here and the more the merrier. We have built the platform which can scale as big as it needs to so hopefully more will find out what we offer.
Another resource here on RCU is Team RCU. All our Team RCU
pilots fly the big stuff and the small 3D foamies too ( http://www.rcuniverse.com/magazine/teamrcu.cfm
). They are here posting on RCU sharing their knowledge throughout the forums and these are the best of the best. I encourage the new members to interact with them in their Team RCU forums or in the electric forums. Chip Hyde, McConville, Leseburg, Somenzini, Noll, Hicks, Sczur, Sabato, Austin, Jesky, Glavin are all part of Team RCU and more of the top pilots are coming soon!
Our mission at RCU is to have fun, share information, help guys find good deals, provide the best and most innovative tools to help modelers and hopefully the larger pool of modelers that continue to gather here provides for a better experience for everyone.
