that is the best video I've ever seen! it looks like it goes a zillion mh : 0

how fast do you thinK?

I've heard about the 60 lx Jett fire being a good engine and a bit lighter but there is no way it has the power of the 46 vx on the DD...

was the launch so bad because of throwing it almost vertical...

that take off looked really bad, I experienced somthing similar with my shark delta, I could not fly it with a larger engine.

not sure what to build. I love fast deltas. My current plane is the pylon coroplast shark with over 100 flights. It's weight is under 3 lbs and with heli 30% nitro I am running at 19,800 rpms on the ground. It is really fast, Gagnon had clocked his at 115 mph level w/ same engine on 15% nitro at 19k rpms. We run OS 25fx.

Balsa always seems to fall apart (because of my ruff landings) but maybe I'll place carbon cloth balsa skin on DD delta, placed order.
