Shouldn't be a problem flying the hornet on a single engine , being the engines so close to one another .... lots of tail volume to compensate asymmetric flight . Flew the mig 29 on one engine and the tomcat too ... no issues at all ..
the way I see it he lost control over one controll surface and was fighting to hold her steady ..
very sad indeed .

Sad to see someone lose a jet after an engine failure.
I recently had a flameout on my FC Mig 29 at the most critical time, just after take off, gear down, and brought it home safely using the same technique as on the full size Canberra, a pig on one engine, a *****cat on two.
I wrote it up on RCJI in the hope it might others to avoid an asymmetric loss, usually avoidable.
Basically minimal thrust, opposite RUDDER and keep speed as high as possible, the F18 with centreline thrust should be recoverable.

(Edited) Sorry....RCU autocorrects *****cat here I was thinking you not wanting to offend Regarding thrustlines on twins, On my 2m SM A10 I was particularly worried of an asymmetric condition especially after deciding on using 2 x VT80 engines (most others used 60N engines) and so I spent a fair amount of time setting up engines to give minimal change in yaw...it looked pretty dodgey but it seemed to work ok.
The forward fuse/nosegear only just held off the ground by supporting nylon chord, each main strut anchored back and a spring tied between more nylon chord and strut, main wheels on ground. Under power both springs would stretch out then when I idled down one engine at a time if it would shift in yaw, I adjusted the higher running engine in or out until I got minimal change. You do have to reference the theoretical thrust line through the fuse as the jet will still move about as the spring tension changes but where it settled was pretty close to a neutral thrust line. Quite surprising how much a little shimming is needed to correct a bad thrustline.

This is from 'gunradds' assembly thread. Been watching with interest to buy one.
Describes his first test flight:
"After doing a few more circuits with it in trim I was feeling pretty good with it. I know wanted to get it all trimmed out with the flaps/slats down and gear down. So I dropped the gear first and not long after that I got a real bad roll to the right. I fought this roll through the turn and realized I had an engine out. So I never dropped the flaps due to wanting to keep her clean. Even on 1 engine the plane had plenty of power just a real bad yaw/ roll to the right. Brought her around for landing. On our feild we have a big tree line to clear before dropping into landing. I didnt want to drop the flaps until I cleared the tree line. So on final I started dropping the power and as expected she rolled back to the left. Got her lined up past the trees and started to drop the flaps and slats but felt I had to add allot of up elevator and got scared of running out so brought the flaps back up for landing just to get her down."

At 0:53 the plane yaws 30 degrees to the right, then pitches up and snap stalls to the right, ending inverted.
I think that this maneuver is key to the problem that happened on this flight. I would be the owner of the plane, I would enquire this point of the flight first.
This 30 degree yaw to the right does not seem to have been commanded, nor the following pitch up input.
I would have a look at the control link as well as there seem to be quite a few uncommanded inputs on that flight ( unless the pilot was relatively inexperienced and very nervous ).
