I've had a Skyburner since '93 with a total of about 160 flights on it. Started out with a OS .61/Dynamax then a .91/Dynamax then a .65/dynamax.
The .65 seems the best combination with good fuel consumption. I also use a PMP pipe. Good 6min flights on 16oz fuel. Initially had fixed gear for a while then switched to SpringAirs. Simple BB JR517 servos on the flight controls. Yes, the weak point is the fwd fuse. joint. I used 1/2" tri-stock with dowels. I also put some carbon fiber on the horz. tail spar. Mount the elev. control horn on the top side, otherwise you'll strip the elev. servo sometime. Mine was nose heavy and after a while I took out the tail weight and put a lifting canard on the nose. Good airplane. Currently retired waiting for a turbine mod.
