Hi Googles,

Meant to ask if you had done anything to beef up the retract mounting area on this plane. If not, do you think that is why the gear broke out?

Thanks,

I only beefed up what I could reach from the open hole. But as I have heard many stories of ARF's gear breaking rails, it happened to me also. And others at the field said I had a good landing and it shouldn't have broke.

So, it's time to beef it up.......I have lots of Carbon here

Hi,

Sounds like a good idea. What retracts did you go with? Did they fit without modifications? Do you fly off grass? I have yet to purchase the retracts and am interested in what others are using.

Thanks,

I fly off grass and am using Robart retracts. After trying to mount them in the orginial place and having them ripe out I redid the mounting system and added flaps which really slow down the Zero for nice landings.

I'm using Spring Air retracts. I have the servo mounted in the stock location and the valve and tank sitting in the center. The tank is nice and small so it fits perfectly and everything is contained to the wing.

I then added the Robart struts which help a bit. One thing I don't like is the retracts are so close to the surface of the wing that trying to mount the gear doors would mean they would almost sit outside the surface of the wing. That's why I left them off.

Goggles,

Man that looks sweet in the air! Glad to see you have the gear repaired.

I'm almost ready to start assembling mine. Just need to decide on which retracts to purchase, and a bit of radio gear and I'll be ready to tackle it.

Regards,

Hi,

I am just about ready to assemble the Zero and was going over the instructions and parts. I think I may be missing one of the smaller 6mm dia. aluminum joiner tubes and was hoping someone who has this kit can tell me how many of the aluminum joiner tubes they have and how it goes together. I have three tubes. One larger 18mm or so in dia., and two smaller 6mmx40mm tubes. I believe the smaller 6mm tubes are needed for the Horizontal stab to fuselage connections, however it also looks like from the instructions step 5 when joining the wing halves together that you need to use the large 18mm tube, and another smaller 6mm tube. This means I'm short one of the 6mm tubes! The kit does include some wood dowels, but those I believe are for the pushrods, not the wing joiner. Anyone with this kit know how many tubes it comes with and where they fit? Instructions are pretty bad, but do show a 6mm tube for step 5 the main wing halves. But do not show which tubes exactly fit the stab attachment step 13 and show 12mm holes to be drilled in the fuse for the stab??. Seems they need to be the smaller 6mm tubes though, which means I don't have enough to go around....

Other than this the kit seems to be of excellent quality, and can't wait to get started on the assembly.

Thanks,

Hey thanks SJN.

I was totally confused. I thought I was suppose to use one of the smaller aluminum tubes (which are actually 12mm and like 40cm when I actually measure them) for the second joiner on the main wing. Now that you show it as a pin, I was able to locate it in the kit.

Thanks again. I promise, no more stupid questions.... Now which end does this propeller thing go on...

I am going to get one of these CMP Zero's but I have 2 projects in front of it. I would love to see the video that you shot. Were you able to get someone to host it for you?

How does yours fly and what motor did you install?

The stupid thing would have been to not ask the question and install it ***** backwards causing a more laborous build and added frustration. Just my 2 cents. Let us know how she flies.

Great video. It looks like the plane flies great and it sounds awesome. It looks like the motor that you chose has plenty of power for this plane. What motor did you install?

YS 120 NC
Graupner 15x8 3-blade prop @ 8500 rpm

It will just prop hang at nearly full throttle. Looks funny doing torque roll w/ a WW2 bird though.

Hi All,
Just starting my GSP 71" zero, I have an OS 120 FSIII with pump, I have a few questions:

1. What size and style spinner are you using?

2. With the OS 120 FSIII with pump, I was thinking of mounting this engine on soft mounts like the Dubro or other, any experience and will this give me enough nose weight to balance the plan

3. I am looking for a pilot bust, where can I find one?

4. Has anyone installed a retractable tail wheel, I have one laying around that would work, any ideas?

5. For the engine I will be using which 3 blade prop should I use?

6. I was thinking of changing to the Robart hinge points instead of the CA hinges, any comments on the stock CA hinges would be great?

7. I noticed going though some of this post that Arf-er looked like he installed a cock pit kit from my view of the photo's, which one did you use

8. Should I use an after marker muffler with this engine or the stock silencer



Any and all help would be appreciated

Thanks
