Red Bull SU 26m
great paint job
Looks like the battery tray has already been made longer so you can mount the battery further toward the tail. I think that was a common mod to get make the stock unit less nose heavy. Most of the people I know flying the plane have also found that the GWS 5043 prop works very well. I also added a couple strips of CF across the bottom of the horizontal stabilizer to make it stronger and add a little more tail weight.
I was very happy with the way mine was flying until I thumbed it nose first into the ground a week ago and broke the prop shaft. Bought a prop adapter that works to get the prop back on without creating a problem with the nose but have not had a chance to fly it since to see if the nose weight addition creates a problem.
I think the thrust angle on mine was the usual down and right when I got it, but with a year plus of repairs etc is a little hard to say exactly at this point.
It really has been a fun little plane. I am trying to decide if it is worth it to tear the motor out and install the stock motor for the SU-26 XP. Was thinking about doing that after I broke the prop shaft, but the LHS was out of stock on that motor when I stopped in.
