Mini R/C Combat Gremlin

The CrashCast Episode 147 of TheCrashCast contained an impromptu segment on the Gremlin. One of my customers in Australia wrote in and it turns out the host, Mike "Crash" Hancock, is a long time Gremlin pilot and they took a trip down memory lane. Now Crash is going to do a segment on the Mini in March 2012 and hold a contest to give away a kit at the end of the month. He plans on flying a couple of the Minis in the full contact combat sessions at SEFF 2012. In Episode 152 I was interviewed and we rambled on and covered how I got started in the hobby, where the Gremlin came from and what RA Cores has been up to these last 20 years and where we seem to be headed. Be sure to check out his March podcasts with the build log of his Minis and for how to qualify for the Mini Gremlin kit giveaway.
