World Models Extra 300S
 

Wondering if anyone has had any experiences with the World Models Extra 300S. I have purchased one and would like any information on setups and flight tendencies/characteristics.

Thus far I am very impressed with the kit as a whole. Each peice/part was individually bagged and tagged. The covering was also flawless, and only required a small amount of heat to get out any wrinkles. I am using a RCS 180 Gas motor with a 18 x 8 Mejzlik prop.

Hope someone has had an experience with World Models aircraft and can provide some insight...

They are GREAT! My 40 sized P-51 is done perfectly with the exception of the fuel tank. My fuel tank slip right along the seam and soaked the front end of the plane with fuel. I got most of it out so it's not a problem anymore. I would get a Hayes slimline fuel tank to fit your Extra just to be safe. Then just glue a thin plywood plate over the hole where the front of the fuel tank pokes through the firewall, and then drill 2 holes in it for the fuel lines to go through. With that done, the airplane should be nearly perfect. The hardware that came with my P-51 was very high quality, and works great. The airplane is also very easy to fly for a Mustang, and is plenty strong for the OS 70 up front. Extras are a little "different" too so I think it should be just as good. I've seen the World Model PT-26 and it was just as good with the exception it had retracts. The real PT-26 didn't have retracts, at least not the ones I've seen at airshow. The PT-26 and my Mustang will land slower than scale. I can't get my Mustang to tipstall either. It will gently drop the lower wing in a slow, steep turn with some up elevator, but at those speeds you are too slow for scale anyway.

Bottom line, you'll love it!

You talking about the new 80" or the old 68"?

Bought it
 

I was referring to the new 80" model...

I went ahead and bought it and have already finished it. Waiting for the right day to fly it.

I was absolutely amazed at the fit and finish of it. It only took very little ironing of the covering to get a great looking plane. I bought the purple one... The only draw back to this beautiful ship was the dinky unscale looking rubber pilot and the limited instruction booklet. But I suppose that if you are buying one of these bigger airplanes you already built one or two previously. Otherwise, I was extremely impressed with the kit and the contents. Hell, it even came with an Polished Aluminum Spinner!

Everything was there bagged and tagged. All of the parts were individually bagged and taped together for security. The instructions could use a technical rewrite to clarify some of the steps for some of the novice ARF builders. i.e., What if someone wants to change the engine type from a glow gas hog 1.60 to a gasser? Took quite a bit of thinking and engineering to get things right and to fit within the cowl enclosure when I decided that I wanted to put a RCS 1.80 on the front of this beauty.

I will report back when the first flight is completed to fill everyone in on the its characteristics...

Should be awsome! Tell us and keep us updated on it

Keep me informed
 

Yes keep me informed.I should have one coming in within the next 4 days.I have been trying to get one since June.(Patty Wagstaff).I have to save up for some servos.I already have a new engine ZDZ 40 RvL Gasser. Thanks MJ

I have assembled five World Models ARF's and the WM Patty Wagstaff Extra will be my sixth. I've had good luck with each WM kit and have always been impressed with the value World Models offers. Unlike some others I plan on using an FX 1.60 in mine as it seems as the plane was designed for this engine. Please let us know how it flies......

Guys,

The test flight/s will be done this coming Sunday the 27th of October, weather permitting... I have attached some photos of it next to my Lanier Laser 200.

I will let you guys know how things turn out...

Okay here are the results of the first flight.

A friend of mine flew the first flight for me, as I was too nervious and felt someone a little quicker on the sticks with considerably more aerobatic flight time un his belt would be better served to prove this aircraft airworthy and in case something went awry. The weather was perfect, party cloudy with just a little wind variable 5-10 mph from the north/northeast, and as it turns out right down the runway. The RCS 180 gasser was a little hard to get started and had to adjust the throttle servo travel adjust. Did the range check and I was amazed at the distance with the antenna down before things fell off (134 paces).

TAKE OFF: The WM 300S seemed to leap off of the ground within about 30 feet, adjusted the the elevator trim 6 clicks (Nose Down). That should help the leaping effect in the future.

IN THE AIR: The WM 300S need 2 clicks of left aileron trim and it flew straight and level, like it was on rails. the vertical was also stright and unlimited. The RCS 180 with a 20x10 proved to be the right combo for vertical manuvers. Unlimited! The throws given in the manual are way to aggressive for first flights and anyone learning to fly TOC or unless you are going to do 3D TOC type freestyle manuvers. I dialed out about 40 percent of the throw on all the surfaces except rudder where I left that at 100 percent. Inverted flight was virtually hands off with just a bit of 'UP" pressure on the stick/elevator. The roll rate was fine at 60 pecent of the manuals recommended rates. Slow flight was incredible... The aircraft slowed down really nice and decided it wanted to push or mush forward and slightly drop the left wing a bit during stall.

LANDING: Landings are straight forward. Keep a little gas on, 1/4 throttle, untill you hit the landing apron and then chop the throttle to a very smooth three point landing. It doesn't get any better than that.

OVERALL OPINION: The WM 300S, RCS 180 gas engine combo is perfect. A ZDZ 40 or a Brison 2.4 would also be a good choice, and perhaps would prove to be a rocketship althought it may prove to increase the wing loading and adding the extra weight. So if you want an aircraft that you can fly for penny's choose one of the gas engine options I listed, but if you want to go through a gallon of glow fuel during a visit by all means go with the 1.60 FX. As I mentioned in my earlier posts, the aircraft is built incredibly well and the fit and finish is wonderful. For an ARF I would rate this aircraft at a 9 out of a possible 10...
