I did the clear seal coat over the white today.  It laid down nice and flat.  3 grams added and still gassing off.  48 grams so for the finish.  Tomorrow the red trim gets painted.

The red trim has been sprayed on.  It is SIG Fokker Red.  A real nice deep rich color red.  Almost a blood red.  4 grams added and still gassing off.  Total finish so far is 53 grams.

Tomorrow I'll sand off the flash then on to the blue.  Not sure if I'll get that sprayed or not.  I have some things to do around the yard.

I like this phase of construction/finishing.  The plane is now taking on it's own personality with each trim color added.  A lot of masking and not a lot of dope being added, but it really makes a difference.

I got the blue sprayed on today.  I use 3 parts of Dark Blue and 1 part of Miami Blue.  It will match the Sapphire Blue Monokote pretty close.  Again all SIG dope.

Tomorrow it'll get the flash sanded off and the canopy detailing should get done.  Then on to the clear coats....whew!  BTW, the blue trim added 2 grams.  Total finish so far is 55 grams.

Here are a few pictures.  I need to add the black letters and AMA numbers to the wing and a few other details.  I added 13 grams of clear for a total finish weight of 68 grams.  I'll let it rest for a few days then get on with installing the motor and such.

Thanks Wade.  I have to touch up the Monokote and clean it up with acetone then wax it.  I have to get those numbers on the wings, then it will look a lot better.  Stay tuned!

After sitting for a week to let the dope somewhat harden, I started installing the electric stuff.  I have the motor, Jeti Spin 44 ESC, Igor's active timer, and Howard's BICAS installed.  Still some more details to do.  I use 3M Dual Lock SJ4570 to hold the ESC, BICAS board and LED's, and Igor's board in place.  I love the stuff!

I finished putting in the gear and all and did a preliminary CG and weight check.  The CG came out on the forward side, which is good, but the weight of the model will end up being 57 ounces...ouch!  I have no idea where the extra weight came from.  The wing ended up being 2 ounces more and would have put the model at 52 ounces, just like all the other electric ones before it.  The weights of everything else was pretty much on target.  I'll have to check my notes and weight and balance sheet.  I'm a bit bummed right now.

Wayne,
I'm planning on going out tomorrow for first flights.  I want to get some outside by the circle.  The batteries are charging as I type.  It'll be a bit windier than I'd like, but it looks like my only chance for a week! 

Pics and report tomorrow evening, I promise.

Well the first flights are done.  It was a bit breezy at Hobby Park in Dallas today.  The tough part about it was the 8 to 10mph breeze was coming off the treeline by the railroad tracks.  Made for a very bumpy choppy flights.  I put in 5 flights and got the lap speed around 5.2 second laps, the wings look pretty level, the handle neutral has been adjusted, and the inside/outside turn rate worked on to get it close.  The tip weight was a little heavy and next time out I'll pull out a 1/4 ounce. That was about all I could comfortably do with those conditions.  It looks like another week of windy/rainy weather.

Here are some pictures of it.  I might spend some time tarting it up, not sure though.  Oh, BTW Tom Niebuhr cut the vinyl letters for me.  They are great!

The final weight so far is 56.7 ounces, all fueled and ready to go.

I do think this plane will be a good flying plane.  The turn is very smooth and I just need to put some flights on it to get used to it too!

The L-40 met its demise this morning.  72 degrees, slight breeze from the South, cloudless blue sky.  The 2nd flight on the 2nd loop of the Clover I got a line clip snag!  Went straight in at about 90 degrees from about 10 feet.  The front end disintegrated. 

The small pieces of a good portion of the nose just drifted off the circle in the slight breeze.  The battery and motor are gone.

The pictures tell the aftermath.

It probably can be repaired.  However, seeing it was almost 58 ounces, 6 to 8 ounces overweight, I'm not going to bother.

You are very methodical about tracking your build weights.  Were you able to determine WHERE the unexpected weight came from?

Dennis,
No, I am stumped.  All the sub assemblies were on target for a 52 oz airplane.  Very similar to the other 3 same size electric airplanes that I built.  The weight must have crept in during final assembly.  It wasn't the finish either.  That was spot on target too.  I can see an ounce or 2 that I would miss by, but almost 6 ounces, that hurt.  I'll track the next one closely too and we'll all see how that turns out.

Crist,

I was in and out of this Thread taking a peek now and again.

I thought you did a realy fine job with this model. I especially liked the Thunderbird stunt team look on the nose and the motor mount. Reminded me of mine mount.

Anyway, I redid a nose and turned a IC model into an "E" model quit easily.

Be a shame not to fix this fine model.

I believe it's worth fixing and I'll bet you could get it back in the air in no time at all.

Good luck with whatever you decide.
