Issac,
What is your source of the carbon stab tube / sleeve ? It is metric and can't locate one in the states.
Thanks,
Frank

As far as I remember it is 10mm.

Issac,
Thanks for your quick reply. I also discovered Hobby King products but was somewhat concerned by a few reviews that described them as not being straight and the wall thickness being too thin.
Shall I assume that you kept the 11mm phenolic tube that came with the kit and just replaced the 10mm hollow tube ?
What is wall thickness of that tube ? Can't find that info on Hobby King's website.
You are to be congratulated for your outstanding workmanship !
Thanks,
Frank

You right, I kept the 11mm phenolic tube that came with the kit and just replaced the 10mm aluminum hollow tube.
I checked my orders from Hobby King and I found that I didn't by the 10mm carbon tube from them.
Now I remember that I purchased the 10mm carbon tube from some local hobby shop in Israel, and I don't know what the original source is.
The inside diameter should be about 7.5mm.
I can only suggest you to ask Hobby King about the inside diameter.
You can also by this tube (TUP 15 0.393" – 9.9822mm OD X 0.29" – 7.366mm ID) and I am sure it will fit properly:

If it's truly ''more powerful'' then it has to consume more energy. Electric motors don't create power, they just convert it. I suppose it could be more efficent therby putting more of the batteries power at the prop but I doubt the Q80 is so much more efficent than the C50 that you could notice it at the prop. The C50 is in the 95% efficency range. It's probably more of a power curve thing and the Q80 power curve hits your flying style better than the C50-14XL did or as I said above, it's consuming more energy.

Hello Ricardo,
The Q80 is more powerful than the C50 14 XL, It is also quieter and does not have that annoying gear box noise.
About the electricity consumption, It looks more or less the same, but I will know better when I will finish the Trimming Procedure.
Best Regards,

Isaac, congratulations for your maiden flight. Just a little question, what´s your impression for the Q80 compared with the C50 14 XL you were flying in the OSMOSE.
Thank you.

About the energy consumption, the Q80 consume 5% - 10% more energy than the C50 14 XL, But it is more powerful than the C50 14 XL.
The Q80 consume about 3,500 - 3,600 milliampere for P11 in medium wind.

Thanks for the report Isaac. I look forward to seeing one first hand some time.

I love this thread! I recently took delivery of a C2 kit and I've been studying every single picture you posted.
There's another thread where people are complaining about trim problems with this aircraft, particularly a pitch to the canopy in knife edge that the can't seem to trim out. Have you experienced that problem?
Could you post your starting point for the CG?
Thanks and good luck,
Scott

I waited till now after I finished the trimming process to answer your question.
Now when I have 40 flights on the plane, I can say that I am satisfied with the way the plane flies.
On the first 15 flights I dealt with that pitch to the canopy problem that you were talking about.
I had to move the C.G. from 220 mm (25% of the MAC) to 200 mm from the T.E. (31.5% of the MAC). And to increase the down thrust.
The final angles are:
Canopy floor: -2.75 degrees
Wing: -0.35 degrees
Airflow: -0.85 degrees
Down thrust: -2.15 degrees
Right thrust: 3.70 degrees
Best regards

Thanks for the reply, Isaac. I appreciate that you waited until after you were satisfied with the trim to respond.
If I may ask one more question...Where did you set your stabilizer angle?
Your thread has been a huge help in construction of my C2.
Thanks again,
Scott

Now is the time to remove the wings adjusters and to save 10.9 gram more (13.5-2.6).
The final weight is 4,829 gram.

RE: Electric ZN Line Xigris C2 Build Thread
Isaac,
Is that typical to put the adjusters on just long enough to get the wing incidence set the way you want it and then remove them? For some reason, I always thought those were left on.
I'll tell you one thing I've learned from this thread... "Patience is a Virtue". I always bull ahead when building my planes. It's like buildng them is some kind of obstical in my way that needs to be cleared. This building season I'm going to slow down and see if I can't get a little closer to the perfection you've shown here with your Xigris build.

Once you are satisfied with the wing incidence you don't need the adjusters any more.
It is more rigid and lighter to use two carbon pins to prevent the wings movement.
You can always put back the adjusters in the future.

Isaac,
I am wondering the purpose of using the long ''thin'' carbon tube after swapping out the adjusters.
thx.

The carbon tube prevents the fuselage from getting squeezed when you force the wing pins against the fuselage.

Hey all,
Today I flew my Xigris, for the first time, with the new Hacker Q80-13S P20 with 20 X 10.5 Ulsamer prop.
I just sensed and confirmed what Bruno was talking about in his thread:
http://www.rcuniverse.com/forum/m_10086881/tm.htm
It flies so smooth with so much power and a great constant speed!
The penetration in strong wind conditions is better then my previous drive set Q80-11S P28 with 21 X 13W Ulsamer prop.
It is easier to maintain constant speed, as it does not change the speed due every incaution throttle movement up or down.
It seems to me like flying with or without EXP, maybe this drive set is the throttle EXP for the electric pattern aircraft.
I also saved 27 gram = (628+82)-(615+68).
I would like to remark and thank Mr. Ralph Schweizer from Modelltechnik for his superb service http://www.ralphschweizer.com/startseite.htm that enabled me to get the first motor from the Hacker production line.
And of course many thanks to Mr. Bruno, Mr. Günter Ulsamer and Mr. Rainer Hacker on the behalf of all the pattern community for developing this motor.
Best Regards,
Isaac Najary
