Repairs are done. It's ready to go. At this rate, sooner or later I will need a shovel and a garbage bag to pick up the pieces.

A little nose weight seems to help this thing a little.

The hinging is so bad that I've decided to add some inboard tip weight. I hope it helps.

3/4 oz inboard tip weight doesn't seem to be enough. It seems to help a little. The plane seems sluggish and clumsy with excessive tension in level flight.

I flew this thing at the KOI today. I got my worst score of the day with it. I got a bad overrun so they docked me the pattern points. The judge also tried to dock me the landing points, but that was overruled.

This could be my worst flying plane. I am considering mounting a heavier engine with more power and rebalancing the tip weight. I have no idea if it will help, but I have to try something.

I have installed an LA 46 in place of the LA 40. I have also corrected a misadjustment between the flaps and the elevator. The next thing to try is removal of the stock tip weight. I understand it is bits of lead imbedded into hot glue. I could try melting it out, or failing that, cut away the structure that the weights are glued to.

Test flew this thing with a recently acquired LA 46. I forgot to add a head gasket. It reminded me. First flight was with 15% nitro. Too fast. Tried again with 5% nitro, set a little richer. Much better. Still need to adjust tip weight.

I added an extra head gasket to the engine. That should calm it down a little. Strange thing, when I had the head off, I checked the plug for penetration into the combustion chamber. It was an OS standard plug, but came up short. I checked for 2 washers, there was only one. I installed a standard long plug and it came pretty close. Seems strange for an OS.

Test flew it today. Feels overpowered and sensitive to the controls. Pulls hard.

I put up one more flight on this thing today. Slightly overpowered.

The fuselage bent at the site of a previous repair. Seems the glue I used never dried completely. This time I epoxied a wood plate on one side of the repair. It should hold this time.

In response to the ply issue
I use poplar for many things on my models
If you have access to a thickness planer poplar would work for your doublers imo
the fuselage balsa running lengthways I would angle the grain one one doubler up and the other side down.. since it is not ply
I'm sure it would work
A piece of poplar goes far in repair work imo

I have some plain wood of unknown type that came to me as protectors for a balsa shipment. That is what I used on this repair. UPDATE: Repair held perfectly, but it hasn't been properly tested. I'm in no real hurry to test it.

I put up 2 flights today. First was too lean with too much power. Difficult to control. Second flight was slightly richer, better speed and control.

I let my partner fly a warmup flight on the NoblARF1 today seeing as I forgot his Predator back at the shop. No problems. My first flight on it today, I destroyed it. I ran out of fuel at a bad time......Yard dart.

I pulled the engine yesterday. The model is is bad shape. Fuselage is repairable, flaps are destroyed, hinge holes in wing are damaged. Front half is intact. Looks like I overbuild the front end and don't do nearly as well on the rear half.

Repairs are coming along. It's a little like assembling a jigsaw puzzle. But then again kits are the same way. That's why wrecks are sometimes referred to as having been rekitted.

the nice part about a profile is that you can just cut another fuselage out and start over. If you had to add nose weight you can lengthen the nose moment and leave out the weight.
