Official FlightLine F4U-1A Corsair 1600mm (63") Wingspan

I wonder if you couldn't rig those cowl flaps with a light spring so that the wind would flatten them while in flight and they would open as you slowed down?
Elbee, what do you think?

All,

That was my original thought and design.

Worked perfectly, though finding expansion springs that fit was tricky.

Ace Hardware had these and as I wrote worked quite well.

I later figured why not 'go for it' and make those 'servo driven'.

A bit fiddly at first, but once I added a sliding arm part, these worked awesome, as well.

The design on Prusa Printables is for 'spring loaded' cowl flaps.

Thanks Dave! We can thank our good friend Elbee for those cowl flaps. Sadly I lack the ingenuity and skillset to make them operational so they are static only. I just love the way they look. With some luck they will help me fly better!

😆

They certainly look the part, that's for sure!! Nice job!

You are both faster and 'cooler' now.

Nice looking plane, Aros! I especially like the cowl flaps and the parachute straps over the shoulders of the pilot. Very believable!

Are your cowl flaps rigged to move in the wind or motorized in some way?

Good luck on your next sortie.

Cheers

Mine has been sitting far too long. Going to take her for a ride tomorrow.

What a beauty!

Got down to business today, took Dangerous Dan on 5 missions and completed them successfully!

Dan,

Truly a beautiful sight.

Looks great!!!👍

She flew great now that I'm zeroing in on the rates and trim. I'm running 60% midrates which seems pretty good. What I'll do is set the low rates to 60 and the mids to 63 and compare, like going to the eye doctor, "Is it better here or here", you know what eye mean

Most excellent repair. Thank you. Best, LB

here is how i handle loose magnets:

Yes, an out runner bell offset will let the magnets hit the commutator (windings). If you look at the prop hum at the very tip running slowly is it rotating straight?

[Joe Hockey]

Maybe a slightly bent motor shaft?

Good thought but would that create clicking ? With the new motor installed and shaft and backplate , we will see this week . If I still have issues then its the ESC lol

Ttaking my Corsair off , virtually at the end of the taxi so speed is high and the water is literally going over the wing ( no exaggeration ) and the model noses over. As I approach the model I glad there is no damage, no broken prop ect.

I revved my motor as a test and it made a strange sound. So I called it a day and decided I would take it home and disassemble it and do more test.
Removed the prop , tested the blades and assembly and it was 100% cleared.
Then I attempted to disassemble the more to determine if I had a loose magnet.
Well like the Wheels on these models , Flightline uses red style permanent lock tight and ( I found ) removing the motor assembly screws is virtually impossible.

Ok , fast forward , I reassemble and test at home , sounds ok. I take it to the field, test /taxi seems ok but remember I am not up to 75% or more in the throttle.
I go to take off and surprisingly the model lifts off at what appears to be 45% power . I was lucky I did not stall the plane . I attempted to accelerate and gain altitude and you could hear a loud clicking . So I turned as quickly as possible, landed successfully and went to plan B.

Plan B, had to order a new motor, backplate and sub shaft assemebly as stated could not get these parts ( apart ).
So in my waiting for a new motor as, does anyone think its my esc and if so should I replace that at the same time ?

My initial assumption is that the jolt dislodged a magnet but is it possible that the jolt ( ground strike ) damaged the ESC and the motor is actually good ?
i am a week away from my delivery of the new motor. Everything seems to point to a magnet problem.

In closing, been asking Motion to communicate to Flightline for 3 years on the red style locktight with no response . I love the Flightline birds and Motion RC, but wish they would make this one simple change to the assembly process . Increasing my wheel size on the Corsair was a simple process that became a major PIA when I encountered the red locktight. Applying heat was the answer but did not want to do so on the motor for fear of damage

Elbee my friend I would consider removing your files from public and become like a Speak Easy. Only those who know get access if you catch my drift.

Dear PP,

A lot more work, but you're probably correct
