World Models Extra 300S (Patty Wagstaff)`
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...
