The speculation is over. I picked mine up tonight at LHS, evidently right off the UPS truck, since it wasn't even in the computer yet.



Wow, am I jealous! I have been looking at this one for over a week, I finally ordered mine today from Esprit Model. Mine is going to be electric (Axi 5330/F3A, Jeti Spin 99, 2 x EVO 6S2P 5000 (for a 12S pack) and probably a 20 x 12 Mejzlik carbon prop). I have to say the fit and finish looks impeccable, the idea of the rear servo cover so everything can be mouted aft yet out-of-sight is brilliant. I expect mine to arrive at Esprit on Wednesday and hopefully get to me by Friday, keeping my fingers crossed!

Go ahead and start a build thread, this ones a keeper! As for assembly, I downloaded the manual from Hanger 9 (PDF format) and it looks like a very, very simple build, all the work is done for you!

I'd like to hear how this plays out, not that I am going to do the same put the electric performance of it.

The speculation is over. I picked mine up tonight at LHS, evidently right off the UPS truck, since it wasn't even in the computer yet.
First impressions:
The box is large. Don't expect it to fit in your car. It's a big plane. I took the parts out of the box and inspected for shipping damage and found none. The covering is typical of H9 products; top notch. I didn't remove anything from the plastic, as I don't plan on starting assembly for a couple of days, and have two planes on the bench right now. This plane looks fantastic from a design standpoint, and even unassembled I can see the lines are going to be great. Took some quick pics, as I have appointments to keep, but here's a quick peek.
I may start a build thread, but it'll be slow since it's flyin' season, not buildin' season , so if someone beats me to it, I'll join in. If you need info about anything let me know.



Nice Work Bench

Now dang it, I told you my bench was full! Just went through the manual. Again typical H9, everything well illustrated...typical ARF, straightforward assembly. However the first thing that caught my eye is the model provides two servo wells for the rudder, but illustrations only use one servo. First planned mod already is to modify rudder servo area and install a high torque servo set up pull-pull. Shouldn't be a difficult task at all, and should have pics up Wed or Thurs night. Also I guess I'll start a completely new thread for build since this one was just info. Haven't completely decided on engine yet,but I'm leaning toward the Evo 26GT. I have a couple of Xoar 16x10 props on the bin that should rip around the sky well.

NOTE: The firewall comes BLANK!! Template provided for Saito 1.80 and Evo 26, but no worries about installing something different. The lack of predrilled holes and blind nuts to mess with your "other than recommended" engine selection is a real plus. Looking like a winner already.

I hear people do this all the time (my Inspire has the same mod, I setup mine stock and have no complaints) but I have to say, I don't get the pull-pull conversion, especially for a plane with such a small (thus low force) rudder. The hardware looks quite solid, I doubt the rudder configured as-is would be any different in flight vesus a pull-pull configuration. I'm not trying to argue or question your decision but do you feel you could honestly tell the difference in the air?

Still jealous!

Reincarnate,

Any way you can weigh the entire thing for me (all the parts, not separate components, I'm looking for weight minus engine, mount and fuel really)? I'm doing an electric conversion and I'm trying to get the numbers into MotoCalc to start finding the best prop combination...

Thank you kindly,

Jack

Status: online 		jfetter...I'll get the weights up Wednesday night. Out of town on business today. My guess is going to be in the 9 lb. ballpark, but I plan on breaking the weights down for everybody to see individual components, and all up weight, minus engine and electronics.

I am going to be using the Power 1.60 and Phx 110 hope to run about 10-12S in her.

Tram,

Electric is the only option for me, I have converted maybe 10 planes in the past 4 years that I've been flying and I love it. I have a healthy collection of electric motors, speed controllers but most importantly, about $6,500 in LiPo's so after that initial shock, the rest is easy to swallow. The only thing I am still debating is the prop. MotoCalc (which is incredibly accurate, this has been proven by my last 4 builds which are right on the money as far as Amps and flight characteristics) shows a 17 x 8 or 18 x 8 is going to give the best performance but I am dying to use one of the Mejzlik 20 x 12 composite props with a composite spiner on this (nothing looks better). I wish Mejzlik made the e-props in smaller sizes, perhaps down to 17" becuase MotoCalc shows me burning about 1,100 watts when the plane's not moving with this big and agressive of a prop (though once in the air it shows an estimated 2,154 watts to the propeller with an estimated top speed of 92 MPH. We'll see...

I'll probably start out with 10S of TP 3850's, maybe some 12S of the TP 3850's and then 10S of our 3850's also..

Tram,

There are many variations, the prop being a major one, you can change the characteristics from a plane that hovers to one that goes 50% faster than the hover-version by prop alone. Here are some numbers I pulled using your desired setup and what the best prop (combined power versus speed) would be;

Kinda' silly, PDF files are not suported so I had to save them as JPG to upload ;-)

I'll be looking for speed on this bad boy.. Not really concerned with power.. I'll have to find the best speed prop for it..

Looks like;

10S = 81 MPH with a 18 x 14 (1,371 watts out, 119 watts/lb. out, 2,603 ft./min. max climb)
12S = 90 MPH with a 21 x 14 (1,650 watts out, 138 watts/lb. out, 3,382 ft./min. max climb)

Have you tried out any of the Zoar Props?
