Yeah...with a RAM500 and the stock tanks, we burn 64 ounces of fuel in about 5 minutes at full throttle (is there any other way to fly?) The Ram500 hauls the Stingray around quite nicely, especially if you pull up the gear. I'm about to order another one for a Winter project so I can take my time and re-engineer some things.
Here's a link to the video I made of Kyle and I flying them in formation...too much fun!
