in the video it doesnt look like 130. i find it hard to believe that speed 8lbs and less than 500 sq " I am think of what engine would get it to 130+ on the level. i know a large DF engine would be to much for the airframe, 60 LX would be close but still doubt it. a modded tower 75 is stronger than the 90LX so might go that route i could try a 90LX fire and then re work it some to get the rpm needed.
