To take it out the box and fly it in less than 1 hour you are not going to get much in the way of look's, when these b777 get some color and detail they will look just as nice as the b737, difference is they don't come with retracts but that does not mean they cannot be added by the builder, the E-flight b777 of the same size does not come with retracts though a lot of builders have added them

Full Scale Pilots...


Fotor, Pulsery, Ben_E, I know there are more of you guys.... I suppose I could do some math but Mings 737 is as we know approx. 1:18th scale... But from the variable weights of our models anywhere from 7 through 10 lbs... What scale are these models in weight to the 1:1 gross curb weight? Name: 737 002.jpg

Full scale empty is approx 84,100lbs.....our 737-700 "should" weigh over 4,000lbs! for scale weight! Try and fly that baby See: http://www.airliners.net/aircraft-data/stats.main?id=95

Bamaguy.... 'preciate the reply but there is some funkie math more than just dividing out by 18.. Its more than that... Figure .. It can't be 4000lbs. I was thinking one would "half" it down..... 84,100 divided in half then in half again... 18 times...Then it would bring it down to about 3/4s of a pound.. but looking at some Google stuff... Yghh.. There is cubic formulas etc.. At an 8 lb. model ..x2 just 16 times is 524000 lbs.. Seems a bit fat too..

Guess what I would wonder if we were giants and lifted a real 737 off the ground, how would it feel compared to what we feel in reality with our models.. Maybe I'm silly.. Still curious though..

Yeah, it's very interesting, indeed. Not being any type of an engineer, the real answer is way above my level! I know the reason the flying weight to size ratio will not hold true down to the "model" size has something to do with the size of air molecules (the constant) and the amount of surface area dedicated to lift, (the variables, area and weight).
I now have drained my brain.

We talk here of "scale air" too... Please forgive... No intentions of draining brains..!!

Almost done I got to do some ground tracking tests today. Still need some minor tweeking to do and clean up some wiring. The 2x HET 2w-18s + WeMotec mini pro EDFs sound awesome with lots of power to spare!! Maiden is still TBD

NiCd + Mabuchi 550 was da bomb
You have to scale volume 3 dimensionally. So 18^3 x 8lb = 46656lb 1:1 scale weight.

Boom... Appears closer and familiar.. Thank you.. So, seems as if "scale" at 8lbs is light for the full size is empty at 84000!
Me... Math wizard no... What would 10lbs. equalize at? (133000 max 1:1 take off)

Cocg thanks for the compliments this is my first ever Foam/ EDF project and I used vinyl (Oracal 651 White) for the fuse. I'm a newbie when compared to a lot of the super talented builders on this thread and I couldn't have done it without their help on lessons learned. I also couldn't have covered that huge fuse without my wife's help I cut out 8-10 sections of vinyl to cover the whole fuse. Happy building

Cheers!

18^3 x 10 gives you 58320lb 100% scale weight.
