Status: offline 		remember to add standoffs (4 oz), ignition (4 oz), muffler (10 oz), battery (5 oz), switch harness (~1 oz), prop/spinner/prop bolts (8-20 oz, depending on prop), etc, to the 2.94 lb figure. Actual weight is over 4.2 lbs.

Mike McConnville said he has flown this plane with the DA50R for most of its flights and reports it flies very well with the gas engine. I assume tthere is a "glorious abundance" of thrust in this plane with that engine. Chances are full throttle is never needed at all.

It seems to me that anything 3lbs and under is fine......since the DA 50cc is 2.94lbs.

I think that gas is the way to go and since I dont already have a 50cc gasser, I shall get the DA 50 unless proved otherwise!

I would think you would have to add all that stuff with the DA too......Right?

This is from IMAA site on what they consider giant scale >

What is Large or Giant Scale?

The concept of large or giant scale is generally considered to apply to radio controlled model aircraft with minimum wingspans of eighty (80) inches for monoplanes and sixty (60) inches for multi-wing aircraft. Ducted Fan aircraft with one hundred forty (140) inches combined length and width, measured from wing tip to wing tip at the widest point perpendicular to the fuselage and added to the length of the fuselage, excluding any protrusions. Quarter (1/4) scale replica's or larger with proper documentation (minimum 3 view drawing of an actual person carrying aircraft) which do not fit the size requirements will be permitted. However, the concept does not encompass radio controlled model aircraft so large as to have the potential of carrying a human being.

15 lbs is not heavy for the DA, but yes it is heavy for this plane. This plane only has 1134 squares which amounts to a 31 ounce wing loading. Compare that to the larger size of the EF Yak, for example (which brings up the reynolds numbers) and its 23-24 ounce wingloading. If you have ever seen a Great Planes Patty Crapstaff fly with a gasser, that's about what you can expect. If you like that, you'll like this, If you have ever seen or flown an EF 50cc Yak, I don't know why you would consider one, IMO. I have been doing some figuring and I don't even see how one could get this thing down to their advertised low of 11.5 pounds, even with a Saito 180 or YS 160...maybe 12.5.
I was excited about this plane for a lighter engine, but I just don't know now. I have My Yak and I don't see the need to downgrade...

Status: offline 		I am sure power is crazy, but the plane itself is heavy for its siz, plain and simple. It weighs almost as much (within 1/2 pound or so) as the EF Yak, yet has 9" less wingspan, and 320 less square inches. Even if you are on a budget, there are several other planes out there that will fly much lighter...remember, flight performance is equally based on power-to-weight, AS WELL AS wing loading/reynolds numbers. I cuold put a DA50 on a 12 pound ROCK and it would have killer vertical performance, but once I let off the throttle it is an instant lawn dart...get it??

Status: offline 		yup but I can come up with the money. I got $600 right now and am trying to sell my Funtana 90. Its in perfect shape and has a saito 100. Its perfectly balanced with the batteries by the firewall and hitec digitals all around on 6 volt with a JR R770 pcm reciever. Engine runs awsome now and it will hover 2 clicks above throttle with byron 20/20. I want $800 and will negotiate al little more for my 6102pcm that I use to fly it with.

Status: offline 		I'm waiting for the Showtime too, especially now. But I think they have stock on this one now. It would be very intersting with that great big Saito in it. But I feel this is just a little too big for my tastes. Sure would love to fly one though.
Thanks,
Barry

Status: offline 		The OS is probably a good choice. I had one on my Ultra Stick 120 and it had massive power. Also the new Saito 220, looks about the same weight as the OS and the new YS160. All of these engines would fly it great I'll bet. Man, I'm almost talking myself into this plane. But, I really think it's too big for me. At least this week.
Thanks,
Barry

Status: offline 		Not sure the OS will have enough power for hover pull out. I am sure the 220 will, but it weighs 42 ounces, compared to the YS160, which weighs 33 ounces, and is just as powerful. Sure, it's $150 more, but definitely the best engine for this plane...under 12 pounds would be very possible.

Status: offline 		Well I guess I will be the guinny pig and try the OS 160 it weighs a hair over 2 pounds and has alot of power. If I can keep the plane at about 12 pounds it should be a rocket. I am gonna put Hitec 5625s on aielerons and elevators a 5645 on rudder and an HS 81mg on the throttle. Plus Lipos for power so we will see if this works out should end up with less than a grand in this thing and keep the wing loading down. Has anyone figured the wing loading if the plane does come in at 11.5 pounds?

I want to see a video or somthing that will show the 3d stuff. couldn't the aifoil affect the wing loading. How do we really know that it will be a heavy flying plane.?
