F4U-4 Corsair to U Control

[ADW 123]

i never bothered with mono. i think the stuff is best used for my rod and reel and fly fishing interests.

sounds like the good ole days. of course, i wouldnt really know.

im happy just keeping it simple. i guess if i ever find myself in that situation where wire is the way to go ill get myself some.

Make sure you prime the motor well, and open the needle valve 4 turns...

good hot battery, and get them fangers outta the way!

[ADW 123]

1.5 V battery correct? i assume that any more will burn out the coil on the glow head.

the problem is, is that it is getting stuck (as in very stuck) in the middle of compression. that happened after i put fuel in the exaust ports for primeing and inside the carb. i didnt even get the sound of a mini explotion inside the conbustion chamber. the glow head either works, or it looks mangled and doesnt work at all right? there isnt any kind of in between where the coils are less powerful and then they break later? i hvnt had a glow head go out yet soo.... wouldnt know...


bottom of the wings- stringers added. reloaded my sading block with sandpaper... im gunna need it for sanding this thing.

[ADW 123]

some progress on the wing. basically all sanded up.






i have to figure out if i have to sand the TE of the inverted gull to shape. it doesnt specify.

[Squishyp38]

Beatiful!

[ADW 123]

thanks squish. of course i might want to do a little more sanding. the leading edge was a pain to deal with, but i took care of it nicely. now, ill build the tail feathers. i cant rele finish the fuse until i know how the tank goes in, which i will look into today.

If the motor gets stuck after priming you are flooded. A few drops in the exhaust are all thats NEEDED.

[ADW 123]

thats what i figured. how do i unflood?

[lukebozek1]

Shut the needle valve and turn it over a few times and try again. Set the valve at 2.5 to 3 turns open.

[lukebozek1]

Or take the glo-plug out blow the excess fuel out reinstall and repeat the steps above. Do you have an electric starter? Or are you kicking it over with the finger that has the band-aid on?

[ADW 123]

i tried that last when i tried to start it a couple of days ago. nothing happened. by stuck i mean pretty stuck. i am sure it had to to with the fuel. i let it sit for a couple of days, and i will try again tomorrow.

for now, no progress on any planes until tomorrow (perfect anyways... no school friday so i get to do whatever)


no one answered the question about the glow head. i assume that when it is out, it looks mangled, but does it loose power and start to dim more and more, or is it like a light buld and just imediatly turn off?

[ADW 123]

oh, and i just flip it over with my hand. i wear a thick glove though. sometimes i use a pencil wich just serves as a chicken stick. i throw off my glove when it starts and adjust the needle valve as needed without my gloves. i havent had any incidents with one of these motors...

[lukebozek1]

When you say stuck, do you mean "locked up" stuck with no motion at all?

[supercruiser]

Not sure what you mean by mangled.

The glow plug coil should be a small, nicely coiled piece of wire. Looks like a spring. It will glow with the 1.5v battery. After the engine starts and you remove the battery clip, the combustion process keeps it glowing to maintain
an ignition source. Thats how I remember it. But, that was 35 years ago since I last worked with a glow engine.

If the crankshaft gets stuck and won't move, you may have too much fuel.
You cannot compress a liquid. If you get too much fuel on top of the piston
the engine will lock up. But you should be able to rotate the crankshaft backwards and unstick it.

Am I anywhere close to answering your questons????

[ADW 123]

hard to move as in quite hard to turn. you said that turning a few times will get it unstuck, but when i tried that it didnt work. ill take a look at it today or sometimes to see if its better.
