Hi Sean.

I got also a CMP Zero 71". The instruction aren´t clear regarding how to glue the two wing half. They mention epoxy and that´s it. Would you like to tell how did you do join the two half and if you reinforced the joint?.


Thank you very much for your assistance

I glued the tube joiner to 1 wing half first. It doesn't matter which one. After this glue is dry, trial fit the other wing half to make sure the alignment can be straight. Then, using 15+ min epoxy, spread epoxy to the rib face of both wings, as well as the tube surface of the 1st wing, and the tube well of the 2nd wing half. After glue is on all adjoining surfaces, slide the 2nd wing half into the 1st wing half w/ tube. After sliding in all the way, use tape to secure the LE and TE to prevent relative rotation of the 2 halves.

Oh man, I am extremely sorry to hear that. Fail safe, there's nothing you can do about that, except for switching channel. At some fields, some channels are better than others. I am on PCM for all my planes, and I still get mini glitches here and there.

Are you gonna get another one? This thing is such a joy to fly. It flies so much like a pattern plane. I've been doing thinsg like square 8, rolling circle, flat spins... If it weren't for the small rudder, I'd try some 3D with it.

hi sean
i think i will buy another one
and i am thinking to put a fm reciver to all my modells because the fail safe
what do you say

I have both the GSP Zero and the Platt Zero still in the box. My GSP is over powered with the OS108 but not greatly. I plan to put a OS 160fx in the Platt Zero hopefully less than 20 pounds. I would want a little more motor in a 17 pound Zero. I suspect the YS 120 and OS 108 are close in power. Platt recommends the OS 108 at 15 pounds.

The Zero is a great flying plane. I will not get to the Platt Zero until next winter. Building a IMP Claude currently.

If the OS 108 can swing a 16x8 prop at 9300 rpm, then it's close in power to the YS 120. I have a feeling the OS 108 is closer in power to the YS 110.

I have rpm data for all 3 engines:

OS 108, Slimline Pitts muffler, APC 17x6, 15% nitro: 9400 rpm
YS 120 NC, APC 17x6, 20/20: 9500 rpm
YS 110 FZ, APC 17x6, 20/20: 8900 rpm

Could be my YS 110 is weaker than the rest. But the OS 108 is awefully close to the YS 120.

Frankly, I think 108 is enough power to fly the Platt Zero, even if it's 17 lb. But when it comes to scale plane powerplant, horsepower is not my primary factor. Rather:

1) weight necessary to balance the plane without re-engineering the hood or clogging up the firewall with lead

2) ability to swing a prop large enough to look nice.

So, frankly, a short-nose design such as Zero at 17 lb, you will need a gas engine to balance it, or a heavy large engine like Moki 1.8. And you want a nice big 16x8 3-blade prop, so OS 160 or Moki 180 would be in the correct torque range for it.



Udi,

Don't go back to FM. If you get interference on a channel on PCM, you will get interference also on FM. The difference is, you don't know what it will do when you get hit. At least w/ PCM, you can program to neutral-idle, so damage to the plane, property, and people is statistically reduced.

I would try changing channels. It's cheaper to get new crystals than to get new receivers. And don't fly too close to other pilots, as 2 transmitters in close proximity will produce a totally different radio wave.

hi sean
i"ll stay with the pcm
when i got the faill safe i was alone not any radio with me
maybe it was a interfirence from the army it hapens some times

What is the number for the Robart retracts....Thanks..

seanychen

My Feedback: (4)

Hi, it is not Robart. It is Century Jet Centurion mechanical retract. I am not sure what number it is. I called Century Jets, and they have a pneumatic retract for this 71" Zero, and they just did something to make it mechanical.

Thanks. I went to the CJ site and ordered their retracts.

Hey I found a cockpit interior for this plane that fits it perfectly from www.vikingcockpits.com of course it has to be assembled and painted , but a great quality product
