Flew the pulse again yesterday and today, the saito is becoming more run in with every tankful, had about 4 litres of 10% through it. The only downside is the crankcase breather is spewing out oil which makes its way back in the slipstream and gets into the r/c compartment, it also gets in between the wing joint and soaks the ribs so, my advice is really fuel proof the r/c compartment well and do the same with the root ribs of the wing halves, I'd recommend covering the root ribs with profilm to prevent the oil getting into the wing compartments ( the wing halves are not glued together but come apart for transit)
The final thing is the battery hatch which is retained by a dowel at the front and two magnets at the rear; these are definitely not up to the job and will not stay attached when the saito powers up, I've taped mine on but it really needs a small retaining catch at the rear.
Elvis has now left the building so I'm off to bed.
Flew it again today, but took the wheel pants off as we share the field with sheep, their, umm, carbon emissions litter the strip and the wheel pants had filled up with this c R ap.
Quite windy, about 18 -20 mph gusting to 26 so I was a bit apprehensive but, hey, she landed whilst going slightly backwards, this lovely plane is really growing on me and the saito 125 is Magnificent!!

Flew it today, after running in the saito 125 for 30 mins as per the instructions.
The model had balanced ever so slightly nose heavy on the cg position, so 3 clicks (bleeps?) of up sorted that, low rates are not very powerful, especially on aileron but she flies as slow as a slow thing and landings are a breeze.
The saito still has the needle 4 turns open, so is very rich but even in this condition a couple of vertical rolls are possible.
I can't speak too highly of the saito, it's turning a master classic 16 x 6 at just under 9000 t/m, god knows what it'll do when it's leaned out!!!
One of the wheel pants loosened up, I swore I put threadlock on it .
This plane sets really high standards for artfs, the only real bitch I've got is the thread sizes, we're all metric over here and finding allen keys to suit the stock bolts is a pain in the butt, so I'm swapping all the captive nuts for metric, but hey that doesn't take anything away from the plane it's fantastic!!!!!!!!
I've literally just glued the canopy on this a/c, the last job and it should be dried by the weekend.
This really is a super kit, I've put a saito 125 up front, there's not much ground clearance for a 16" prop!!!!
Couple of tips for other would be owners, put the switch in before the servos otherwise it's a pig of a job (even with lipstick ), the rudder and elevator are operated by wire pushrods in nylon tubes, defo not friction free; I heated the wire up with a hot air paint stripper and poked it up and down in each tube, now much less friction. Looking forward to flying it.
The Extra 300S has flown, the engine, a mk 1 Irvine 60 is far too noisy with the standard silencer so I'm having a mini quiet pipe made and that will be with me on the 16th.
