Anyone other than the RC universe reviewer have this plane?

If so, what size power plant are you using.. Im wondering how a OS 91 Surpass 4stroke will pull this thing?

Any other fight characterists or info regarding this plane is appreciated.

I had one of these planes,

I used a Saito 100 came out about 7lbs, fairly light for ARF.
It is quite well constucted and flies very well.
The landing gear a on the soft side though.

I used pull-pull for the rudder, easy to set this up instead of
using the wooden pushrods.

I would not recommend a 61 2 stroke though,
you want something which can swing a minimum 14" prop or so.

If I had to do it again I would put a 120 4 stroke for unlimited power.

I have one with a magnum 91 and its a blast to fly, and does hover but not much power in reserve. lennyk is correct a 120 would deliver unlimited vertical. I think the OS is more powerfull than the Magnum and you probably will not be dissapointed, unless you want after-burner like performance.

TO YOU GUYS THAT HAVE THESE PLANES, WHAT DO YOU THINK OF CONSTRUCTION AND FIT? HOW WOULD YOU RATE THEM?

Super Kraft Extra 300s 60
 

The kit construction is top notch! It is built and covered as well as some of the nicest kits I have ever seen built. If fit and finish is a main concern, you won't be dissapointed. I am very impressed.
Considering the quality of many mainstream ARF companies like Hobbico, this just simply is in another league.

In short, get one.

Thanks smgfromny for the info. i have been considering getting one and this info helps.

Super Kraft Extra 300s 60
 

construction is very good, covering is very good.
If I had to buy one again I would buy it.

Required zero trim.

Agreed, dollar for dollar I don't think you can do better. PHILLKO, they are carried by a lot of hobby stores, If you have one near you have them open the box, you WILL be impressed. If they don't, have them call Kangke. My LHS only took 3 days to set up an account and get a couple in stock. :D

I got my son one of them as his first low wing plane. It's excellent ARF quality.
We did replace the landing gear after a few flights as it is very soft. Used gear from TNT. When I replaced the gear, I also moved it a little further forward as the plane tended to want to nose over on the ground.
Have a GMS .76 in it which works fine for my son. Has good vertical, but not unlimited.

I have one on the table right now. I am wanting to take a small step from my fazer to bigger planes. I wanted something priced good and hoverability. Will a magnum 91 hover it? What is the minimum 2 stroke and 4 stroke that would hover this plane?

Check out the previous posts in this thread, OUTCAST has a magnum 91 and says it does hover.

91 in the Extra
 

I can tell you from experience that a 91 will not hover the GS300, which is very similar to the Extra. I have a Kange Staudacher GS300 and have a 91AC in her. She flies but on the wing and will not come close to hovering. She weighs in @ 9.5 lbs. Wet. I am in the process of installing a YS 120NC now so I can tell you more next week.

We have conflicting reports here than. I am looking at a Magnum XL 91 two stroke. I found one at a LHS for $90 brand new. Just needs a pitts muffler. What props are you guys running? OUTCAST? Crash King?

91 Two vs 4 Stroke
 

Well I was using a 4s YS91AC and I tried props from a 14x6 up to a 15 x 8. The 15x6 Zinger Pro was probably the better prop in my opinion. It would run up well and deliver sufficent power and speed to fly the plane. I think a 2 stroke should be a great (hover) power system. It will also keep the weight down. I saw that somone got one of these flight ready @ 7lbs which is a full 2lbs under the weight of the Staud. So I would say a 91 2s should be the ticket, if it is a 4s I would definately go 120.

Extra with GMS Question
 

lenough,

Are you using the stock muffler on the GMS 76? If not, what? Can the stock muffler be mounted on this plane without major mods. I have a GMS 76 that I got a deal on that needs a home. The Kangke Extra or an Ultra Stik 60 are the leading candidates.

thanks,
Bill

Bill,

Using a Bison Pitts muffler. Got a good deal on the engine and muffler from GoldenState R/C.

Crash King, I'm not familiar with the GS300 but if yours weighs 9.5 pounds I can tell you its not related to the extra 300 or is in serious need of a diet. Lennyk's plane came in at 7 lbs mine came in just short of eight wet. It will hang on the magnum 91 FS until it runs out of fuel, the engine makes just enough thrust to climb vertical from a hover but it does not accelerate. I run a APC 15/6 on wildcat 15% and the measured thrust on my digital fish scale is 8 lbs 13 oz. I used HS525BB servos on the ailerons and elevator, a HS545BB for the rudder, an HS81 for the throttle. I can save another 3oz by removing the wheel pants. I did replace the hardware, wheels, axles and push rods but other than that its stock. My only complaint is that it needs more control throw in 3D mode. :)

Weight?
 

Im a little concerned, I just weighed my Extra on the digital Bathroom scale and it came out 8 lbs. DRY with no Reciever or battery!! I cant figure how some of you guys have them at 7 lbs wet! Whats the secret?? I didnt add a thing to the construction? I did however notice the wheels and pants were noticably heavy.

Suggestions??? Is it going to be too heavy?

Super Kraft Extra 300s 60
 

I'm not sure, but if I recall the fuse/wing weighed 5+ and the radio/engine took it to just over 7lbs. I did not use wheel pants though. I also changed the wheels.

The plane was written off in a midair, I checked the wing and
it did appear to have quite light balsa in it, I guess this could vary
somewhat.

Saito 100 is not a very heavy engine also.

smgfromny, a large number of things control the weight of a plane, its not just one thing thats a secret. For instance, changing the wheels to light flights saves about 1.5 oz, by using the light weight HS 525 servos I saved 1/2 oz per servo times 5, and because they are not "high torque high draw" I was able to use a 800mha battery insted of the 1100-1500 mha most use saving another once. I saved 3 oz by using a light weight motor mount. We saved another .5 oz with the pushrods, so in this short list we have saved over 1/2 pound and thats before we make any attempt to lighten the airframe. If you add your reciever and battery then subtract that 1/2 pound you to will end up at about 8 pounds wet, and by the way you can save as much as 2 onces in the selection of your reciever, you can save 1/4 once in the tail wheel alone. Its all in the little things that make them fly good. If your going to load up with digital servos, big batteries, larger fuel tanks, heavier landing gear, extra glass reinforced firewalls, extra epoxy fuel proofing, and so on you can't expect it to be light. :)

Phillco,
I have the GS300 Kangke and the Sport Cap Kangke... both are excellent kits, and are well made... I have had some hard landings (due to pilot, not model), and they are hanging tough, and looking good.... pull-pull is a good idea on the rudder, I'm thinking about that now... I have a TT .91 4s on the Sport Cap... it has plenty of power, and tracks great with this engine.... I have a magnum 1.08 on the GS300, stock muffler... perfect fit IMO... unlimited vert (my definition of it anyway) with a 14X6 APC... You will like these Kangke (super kraft) kits...

Super Kraft Extra 300s 60
 

I have been flying and tweaking the Extra 300 for two weeks now. It has to be the best flying/looking plane I ever had. I put a Saito 120 into it and it is very impressive! The plane is a dream to fly. It tracks like p pattern plane but can do anything 3D I ask it to. The kit was not perfect (some minor problems with fitting a 120 in the cowel) but it is by far the best I have ever flown.

I have one they are real nice planes for what they run you. A good 90 2 stroke is a must on the Extra, I am running a 90 2 stroke tiger shark and I'm not real happy with the power of this engine so go with an fx and the plane will be a riot. Did I read it right ??? someone came out at seven pounds with their Extra?? If you did I would like to know how you did it. Short of cutting about two pounds of balsa off of it I couldn't figure out how to lighten it. They are built like a tank and I mean that in a good way,I do think the plane could handle a 1.20 2 stroke and would be even more fun. One thing the Kangke extra will do is teach you to land at a real good clip and man is it purty. I am putting together one of Kange's GS 300's and it will have a g.m.s 1.20 for power WeeeeHaaaaw.
