What info are you looking for? These were made in the 80's.. and one of the coolest planes out at one time. I had one in 1986...
The Diablo was here before Extra's, Edge's, Sukhoi's, etc.. It was around the era of Cap20 and 21's.. One of the better aerobats.. if not the best of its time. The Laser was right there with it though.. still these were a step above in my opinion. There was also a large scale version from EZ...... identical in looks only scaled up. The smaller version you have flies very nice with a .91 or so 4-stroke. OK Models/Pilot also had some high end kits of the Diablo.. builders kits..again some of the best for that era.. one had to be pretty much expert to successfully complete one of those extensive kits.
I don't have any CG info on it, if I'm not mistaken.. the CG is printed right on the outer skin.. thats a vague memory for some reason.. we are talking 26yrs or more ago that I had mine.. haha.. I've got a decent memory.. but I can't remember the CG info from that long ago..whats wrong with me..??
.. I can vividly remember that thing being a beast though.. in that it was all out performance..very fun plane.. I don't know if all this helps.. but its info anyways.. and a free bump. I always did like this plane.. wouldn't mind having another one..but theres so many more out there now.. I've moved on.
