I purchased this rather old glider from a club member for very cheap as a project plane.  As I got it, the nose of her plastic fuselage was cracked, her uncommon shaft size folding prop was broken, though a spare was included.  Also, a spare unused wing set was also included.  Worth it just for the pair of 1.25m balsa wings.  She was also still running on a geared brushed motor and NiMH 7S battery.

Repairing the nose was awkward, but not too bad.  Awkwardly placed clamps and expoxy did the job.

I put on the spare prop and tried a test flight, which didn't go so well, resulting in a small crash which broke the brittle prop.  I had planned on replacing the power system anyway, so this just pushed me towards that right away.  My suspicion was this was a combination of a barely adequate power system and my not being used to it.

I swapped in an arguably oversized brushless motor and ESC.  This combination has equal power to weight, which is much more than needed for a glider.  However, it was a very good physical fit, and I'd rather oversized then undersized.  To fit, the motor directly screwed in, I just need to mount the wires so the wouldn't run against the can.  I'm worried about overheating as there is no airflow around the motor, only behind it, but will see when I fly it.  I'm hoping that given normal glider use of low throttle and most of the time no throttle should be ok.  After more use, I'll probably adjust the throttle curve so that full throttle isn't used, or only for takeoff.  Swapping to 2S is another good option.

Despite the more power, this system, including 3S 2200 lipo, cuts 350g off the weight.  The battery needs to move from under the wing all the way up to the front.  So there wasn't really any purpose in going with a smaller power system as I'd just need to add extra weights.

To keep the out runner motor can from abrading the wires, I fashioned a plastic clip to hold them against the side wall.

After a test toss, she lost control and crashed, requiring a bit more glueing.  I thought what was going on was a small gust of wind tipped her, and i couldn't right her with just rudder and dihedral.  While that may have impacted things, a larger factor I think was that with as much weight as she has, she needs higher speed than my toss, and it was more of a stall.  But then the next issue.

My next go was with no wind, and motor power on.  After a little pitch up, I quickly pushed forward to prevent stall, and she pitched up more.  I instantly realized the elevator was reversed, but in that 1/2sec time window to realize that, it didn't leave enough time to counteract instinct on elevator control.  Worst crash yet, denting one section of the wing, and crushing in an area from the hold down rubber bands when the wing hit, only one tip, twisting it.  Sigh.  Checking control surfaces is one of those things that even when done every time(i did here), you can get in such a habit that is more of an instinct, not actually thinking about each motion, every time.

I was able to patch her.  Some extra CF strips on the fuselage front, and a patch in the balsa sheeting on the wing.  Next flight out, after triple checking the servo directions, was successful.  Kiki definitely requires quite a strong toss, just barely above level so she can get enough speed.  But she flies delightfully.  She needed a little down elevator mix about 6%, from throttle to balance out lift with throttle.  

After a couple flights the motor started major vibration.  Seems like previous crashes weakened the firewall such that it would flex, allowing this vibration.  With the somewhat narrow gap between the motor and inside of the fuselage, this caused the motor can to rub against the fuselage inside.  I'll need to add a layer to the firewall to strengthen it and reinstall.

For awhile I was pretty sure I wanted to convert her wings to have ailerons/flapperons, but after several good flights, might not be worth it.  I'm not a fan of flying without ailerons, but I'm getting more used to it and will see in the future.  This said, flaps could be really useful in landing as she comes in really fast.
