Hi Ming,
The winglets were a modification to reduce the tip vortices.This was not done to improve handling.but did markedly improve long range fuel efficiency.I worked as a mechanic on 737-700's and 800's for a bit and this info comes from Boeing.Here's a couple birds I worked on.

Thank you!
I understand the winglet is for improve long range fuel efficiency.
But I also want to ask the question to 737 pilot Mike, is it any difference on handling on the real one.

Hi Ming
I really donít remember any difference in the way the 737 flew with or without the winglets. Some of our -700ís had winglets, and some didnít, and from what I remember they handled about the same. Also, all swept wing commercial aircraft have yaw dampers, which control the rudder to prevent adverse yaw, and so most differences in the way the airplane might feel in role would be masked by the yaw damper. I hope this helps.

+1 for winglets on the model.

Im glad to see you are making more airliners, definately a sector of the EDF market that is under explored.

When I worked as an aerospace engineer one of the last projects I worked on was the winglets for the 737. Actually, I had done stress analysis at Boeing early in my career. Then, at the end of my aerospace career I was working in marketing for a company that built aerospace structures for many different aircraft and satelite manufacturers. When in that last role I approached Aviation Partners regarding those winglets. They had a small staff of retired Boeing aeronautical guys and had come up with this great shape. I stood at their whiteboard one afternoon and, through sketches and blabbing, described how they could go about getting those attached to existing aircraft. My company, as was often the case, priced themselves out of the competition so that was the end of my involvement. It was an interesting addition to a great airplane.

Right after that I left aerospace to make more money designing HVAC, plumbing, and fire sprinkler systems. Aerospace is a lot of fun, but I've got bills to pay.

You guys are ALL wrong....winglets were added so the 737 could fly knife-edge better!

Absolutely agree that this is a market that is under explored. Good to see Ming developing airliners at an affordable price.

NO....... when flying over the equator and both forward and aft lavs are flushed the winglets prevent the plane from entering a flat spin.
