is a B-24 ARF that is 4.24 meter wingspan. Made in China, not sure if it is available in the US market yet.

Got to see a Dual Ace fly today. A guy I fly with just put one together and maidened it this afternoon... I will say this, it is QUICK! He is using two Evolution .46nt engines. Unfortunately, he did a slight amount of damage to it when the right engine quit on the third flight, but nothing too bad. It will be back in the air again this week.

What caused the 'bump' when the engine quit. Did he turn to the right (dead engine)?

No, actually he turned to the left, and was trying to climb to come around and try to make the runway. I wasnt watching it real closely, but I did see it roll inverted and go into a dive, so I am assuming he just got it too slow and stalled. He pulled it out of the dive, but it was a bit of a handfull by then, and he just ran out of sky.

Thanx Guy's the B-24 is what is needed I think it was one for Model Engines.,Aussie. One of or what is to come have to wait and see. That would be magic.
