i have a DLE 55. It is sold as a 50ccer. I have a DLE 35RA on a Grate Planes Super Chipmink, It's a 80" plane and go's like a bandit with a 16X10 three blade prop and go's not to bad with a 18X8 or even a 10. A 55 would give me the nose wight l would need! Yea That Would Do it! Thanks for the seed! LOL.......

Man,, thats a peace of work there. I like the way you used the brass elbows instead of trying to bend and drill. That's what I would of try'ed to do and I probably of spent a bunch of cash and it would of fell apart any way. The way you built it, it will stay together for ever. Notice I did not say (probably) LOL...... I'd like to see the finished product and a flying video. I love the cockpit. Like to know if the canopy is functional and how you worked it out. If you would, I'd love to have some (hand photos) of this plane to follow by. If you don't mind send me a phone # to my E Mail and I will give you a buzz. Keep up the good work. P.S. I like the gun ports and how munch did you have to move the servo tray? Thanks :-) deadmeataircraft@gmail.com

Sammy the servo tray was left completely in tact , I built the cockpit around the tray and my reciver and one servo for the throttle is hidden inside the cockpit in front of the instrument panel, I had planned to hook the pilots control stick to the servo directly underneath that controls the rudder, so his hand will move the rudder ...... the canopy is functional manually on rails but I haven't figured out a way to hook up a servo and save the weight from the tail, I'll post some pic soon

Cool, may be abel to use a small cabel on the underneath side of the sliding part of the canopy and hide the caber under the canopy upper frame?? It could work. Thanks for the come back. :-) Could use one HS 55 servo on the canopy, or maybe two with two HS 55's with two cables.

HI everyone :-)
I hope this theread has not died .

I nearly killed my Zero the other day.. got overwhelmed by the torque on take off.. and was sure I'd make it on the correct side of our safety net.
I didn't.

The left wing took the blow and got nearly pulverized by the wheel vell to and all the way out to the aileron.
The rest of the plane took suprisingly little damage. Some scratches on the fuse, and a new ring for the cowl-mount, but other than that all good it seems.

So in the need of something better to do i started glueing the toothpics together to get a frame to reconstruct the wing.

The formers are NACA2415 so they're pretty easy, and the main spar was salvageble to such good shape that I was able to copy it.
Then the next task is to reconstruct the channel for the wing joiner tube.
the fiberglass outer tube is ok to reuse, and I have found an 18mm aluminium tube to replace the one who broke in the middle.

As of now the wing "frame" is tacked togheter, but I am not certain of the dihedral.
So if any of you guys read could please measure the angle either in degrees or measure the angle in centimeters on the tip (while the other half of the win rests on a level surface, )that would be much appreciated.



As you see, it's comming together again.. hopefully by chrismass so I can start on the real winter project. ( this was definately not planned )
But now i need the correct measure for the dihetral.

Cool or170b :-)

I've just started on another attempt to make a new canopy..this time by making a plug from plaster and vacuum form some PETG over it. Hopefully this will be an easier way to get a new canopy, than my last attempt with building foam and filler.

I still have mine, but the last time I flew, the engine wouldn't slow down to idle. Landed in grass and plane come to a stop eventually. Not a servo problem, throttle butterfly is closing all the way as far as I can tell. So plane is down until I can get this sorted out. Engine is converted one with side carb. 25cc. Over 200 flights on this plane. It is one of the best flying warbirds that I have.

Good looking Zero :-) What size is that spinner ? And the prop is 16" by..?
Have you checked your motor for loose screws and, then if yes, checked for leaking gaskets/ o-rings?

I haven't looked at the engine or the carb at all yet. The spinner is 3" diameter. Prop is Master Airscrew 3 blade 16-8. Since that picture I have replaced the prop with a ASP 17-8 two blade and an ESM spinner for the 72" wingspan FW190 which is almost the same profile as the Zero. The ASP two blade gives a little better performance. The plane is a bit heavy at 15.9 lbs. With the short nose, even with the heavy converted engine, both batteries in the engine compartment and a heavy hub, I still had to bolt a chunck of lead to the engine mount. I also added scale split flaps which really help with the landings.

I havn't investigated the carb or engine yet. I'll get to it in a few days. The spinner is 3". Prop is Master Airscrew 16-8 three blade. It has been replaced by a ASP 17-8 two blade with an ESM spinner for a 72" wingspan FW190. The two blade gives a little better performance. The plane is somewhat heavy at 15.9 lbs because even with the heavy converted engine, batteries mounted inside the cowl and a heavy hub, I still had to add a chunk of lead to the nose. Also added scale split flaps and redesigned and rebuilt the gear mounts. The original gear mounts a way too fragile for my flying.

The last picture is the wrong plane. Those thumbnails are too small.

Love the look of the radial.. have to make one myself. Somewhere I have a plaster plug that i'll to vacuum-pull a petg dummy. It's from a 60 size Corsair, but I don't think anyone will tell the difference to the Sakae ;-)

Speaking of motor.. I have installed an ASP 180FS into mine.. 30 ccm, and I added electronic ignition with a sparkplug instead of onboard glow. still running glowfuel, and runs like a charm.

The engine of the Zero is fixed. Turned out it was a leaking gasket between the carb and insulator block. The hole in the gasket was slightly large and the bearing surface on on side of the insulator block was very thin. I had another gasket in stock, slightly smaller hole. Replaced. Engine ran great. Three flights on the plane the other day. I think this plane is one of the best flying warbirds. It has large wings, large tail surfaces, long fuselage and wide gear.

I managed to find a 120. Zero un built in the box, I set it up for E power and mounted the batteries in the cowl, also I added flaps and a dummy radial engine left over from my cmp fw, I got it maiden'ed yesterday and 2 more flight's, it flies great :-)
A couple of more flight days and it goes into the hanger for paint and detail
