Unpacking the box I was happy to find what appears to be a good quality kit. The main pieces of the plane were in plastic bags.Everything intact .. not so much as a scratch!
One sore point .. but to be expected from a Chinese Kit .. poor instructions.Shouldn't cause any real problems though .. most of the build seems pretty obvious. Love the line :-
"Assembly the tail,concreting after user". What am I building here, a plane or a path ??
When I picked up the model from Aussie Flight, I also grabbed 3 9g servos to use in the Corsair.
Inserting the servos was easy, although it was a tight fit. I slightly filed the edges of the servo bays to mount them.. taking care not to break the plywood. It seemed pretty tough though.

It was a nice wooden base to screw the servos into.
Mounting the motor.
Removed the cowl by pulling in off! Using supplied brushless, with gearbox already attached. The wires didn't want to pass through top slot. Drilled a hole in bottom and passed wires through there.
Didn't need to elongate wires .. long enough to reach Tournigy 30 amp esc (overkill at 30 Amps .. but it was the smallest spare one in the drawer)

Threaded the ESC wires though the firewall and plugged in the wires before screwing home the motor to the stick mount.(I taped the wires together with excess pointing out at the front .. poked the excess through hole and pulled!)
Connected the motor wires and mounted the motor to the stick. Before PUSHING back the wires into the fuse I checked that direction of the motor is correct by attaching a battery and receiver (Channel 3) and attaching a prop and seeing it is spinning in the right direction.
When I found the motor was spinning in the right direction I secured the ESC to the firewall with double sided tape.
ALL good .. very easy so far!
Threaded the control rods through the fuse .. they were WAY too long. I attached some Linkage stoppers to the servo horns and used the straight end through the fuse and cut off the end with the bend in it. You could use the bent end throught the servo horn just as well.. I just choose to use the linkage stoppers .. they make it easier to adjust the control rod positions later.
Bent the z bend (well sorta a z)into the rudder rod. Then attached the horizontal stab and elevator assembly - Pre attached elevator nice !!!

Attached the elevator rod after cutting off the excess. I used little plastic clips to tie them to the horns .. don't need to .. I just like them.
Attached Tailwheel, I used the little brass collets on the inside with the retainer with the small hole, and tightened up the grommet screw to lock it on. Attached the wheels to the landing gear. Usually I use little brass grommets inside ..the siver locking retainers on the out. I think the landing gear change (the plane on the box has typical GWS wheels) has not given us the right parts! The brass collets dont go on.I used a little plastic locknut thing instead, and one of the brass collets on the tailwheel .... who knows ?? Attach them to the wings with screws supplied.
Attach the wing servo to athe Rx to centre it up then attach the linkages to the servo and lock into the aileron horns with the attached plastic clips. Be careful to make the ailerons as close to centred as possible before locking in the plastic clips.
Finishing the plane consisted of attaching the cowling into place. Bolting on supplied prop.
Triming and Epoxying on Canopy. Epoxy the ailerons where the pushrods connect to them .. they work loose easily! Epoxy ... dont bother super gluing!
I put a 3S 2100 lipo into the battery bay. This battery weighs in at 161 grams. This wasn't enough to balance the plane up. Unfortunately the pathetic Chinese instructions gave no indication of COG. I learnt from another forum (Guanli Corsair) the COG is 55 mm back from the leading edge near the fuse. Invert the plane to balance. This worked pretty well, but to get it to balance required a fair of of lead in the nose. (Heavy double sided tape in the bottom of the cowl)
MAIDEN
Nerves on maiden are always present .. and this birds maiden was no different.
Chose an area with a poor runway and consequentialy hit a lump of mud sticking up and smashed off the nose. Pointed out one thing :-
The nose of this plane is very vulnerable.. I reattached it easily and glassed the inside of the 'thin' area on the left and right on the inside of the fuse. MUCH stonger now! Also ripped off the landing gear easily. Epoxied the plastic mounting plates back on.
Re-maidened and she flew wondefully. Needed quite a bit of up elevator ..and a bit of right aileron ... then rock solid. Decent roll rate ... poor looping ... But GREAT plane. I am really stoked. CHEAP and just great!
I will most certainly be buying another of these planes! Just which one next ???
Here's a link to the maiden (+1) dead camera battery on maiden ...
