Default Richmodels Japanese Zero

Alienx asked me to post some pics of the Zero I'm starting on this weekend. Not really going to do a build thread on it but more just wanted to post a few pics.

It's a Richmodels Balsa Ultracote (type) build up.

Wingspan 37"
Length 29"
Weight 18 oz. (I think it will actually build out to around 23 oz.)
Wing area 221.7 sq in.
E-Max 2215-25 brushless
RCE 30 amp ESC
DN Power 3S 2150 15C Lipo
3 ea. SG90 servos
DX6 receiver

Final Specs:
AUW 23.4 ounces
14.2 amps
166 watts (114 watts per lb.)
APC 10x5E prop
Built as a belly flopper


Haven't decided if I want to put the gear on it. I'm almost thinking of making this one a belly flopper. It has a nice smooth bottom to slide in on.

OOOH, that's a internal servo/torque rod plane. And only 18 oz. I'm done!

Thanks for the pics.

One good thing about the weather is that I got a lot done on the Zero this weekend. About all I have left is to get the battery straps in, paint the prop tips yellow and set the CG. I figure I'll get to maiden it in June the way the weather is.

Nice Tom, Kinda like me, build, build, build, and no flying till spring.

Now if you can get it in the air with the 38, that would be a sight.

Thanks Brad.

Would be kind of cool to get a picture of a low flyby with the two of them in formation. I could also put the P-38 and P-47 and Spitfire with the Stuka. So many options, so few hands.

Thanks Paul,

I was actually just opening the box to my P-51. It will either be it or the Pitts Bipe. I just finished getting the zero balanced and putting it on the watt meter. It's running the E Max 2215-25 with an APC 10x5E prop. Reading 14.2 amps and 166 watts. The AUW ended up at 23.4 ounces so that's about 114 watts per lb. Should fly nicely.

If you need more hands for photo ops, I'll be happy to come down and fly all of your planes for you. I'll even fly in the wind!

Once.

Come on down! I'd love to have another person to fly with. For a small deposit, you can fly any of my planes.

Tom, do the P-51 next, I'd like to see how yours comes out.
I told you I get easily pushed in other directions, my P-40 got pushed back again.
On the plus side I finished another sport type and am into a "Shoestring" racer.

Ok, just for you, I'll do the P-51. I'm waiting on the motor, ESC and servos for it. They should be here Saturday or Monday. If you have a few DX6 receivers laying around that you don't want, pleaase send them to me.

Here's a picture of the Zero all done. I painted the prop tips and the inside of the canopy so you can't see the receiver and all the wires. Don't pay attention to the two little pieces of blue tape on the wing. They're to mark the CG point then they'll come off.

I like the tape for the CG. I also do that as well, matter of fact I forgot to remove the tape on the P-38.
It's still inside the canopy.

Glad you're doing the P-51 next.

If you're thinking about putting the gear on it, you might want to bend a new one.
The supplied one is a little short, should work OK, just looks funny.

Actually, I had just spread it out on the work bench (kitchen table) and was thinking I might make it a belly flopper too. The only thing would be the scoop on the bottom might act like a plow so I'll probably put gear on it. Thanks for the heads up on it.

Finally got a break in the weather today and got to maiden my Zero. She flew great! All it needed was a few clicks of left aileron and it was straight as a string. Only one little mishap and that was on the landing. It's a belly flopper and I usually bring them in a little hot on the first landings to avoid a stall at the last moment. The prop caught on the grass and snapped. It also slightly bent the shaft but it's already straightened out and has a new prop ready to go again. It really is a very nice flyer. I'll try to post some pictures when it warms up a little. I also got to fly the P-38 again today. I REALLY like flying that thing. Hopper's Neighbor maidened his Pitts Bipe too. It also flew great and he did a great job for his first maiden all alone with a balsa plane. The landing was picture perfect.

Pretty cold but a good time was had by all.

Grasshopper,
I have a brushless P-51 (A-K Models I think) with a really flimsy scoop on the bottom. I thought for sure it was going to tear off right away, but to date its been fine- and I don't always land so hot. If you prefer not to look at gear hanging down, might want to give it a shot belly landing.
Cheers

Hi K,

Is this the same P-51? If so, I'm just finishing mine up but I already installed the gear.

http://www.avia-richmodel.com/Produc...RIC-P-51D.html

My Zero didn't need to land that hot. I just wasn't sure how she would float the first time and I didn't have a lot of time to fly it. Only got one flight in.

Thanks Andy. The weather isn't great but it was calm. Still in the 20s though.

Just about done with my P-51. Just need to finish up the battery compartment, paint the prop black with yellow tips and balance it then it's on to the Pitts Bipe.

Here's a pic of the P-51 so far.

Looks nice! I am going to have to get another P51 at some point. I never had much love for the plane until I got my Marie on sale from Hobby Lobby. It really grew on me. Very aggressive and sleek plane! Good luck with it.

I like P-51s too but they've never really been my favorite warbird. This has been one of my least favorite ARFs to assemble for some reason. I am anxious to see how she flys though.

Hi Tom, you're in the wrong thread.
I like your P-51, like the green in the cockpit.
Did the name come through as "Marie" or did you change it?
