66tbird...I got the AUW of the bomber. With a 1000mAh 3s LiPo the all-up-weight is between 14 and 15 ounces. The plane is 6mm Depron and I do not know how that compares in weight to FFF. Richard Stultz who scaled the plane down to this size and owns and flys a full size 8'ws) Bomber thinks this small plane performs exceptionally well and has a really decent glide ratio. Needless to say, a smaller battery will fly it fine and save some weight. Maybe 5gm servos will save a little weight also. Hope this information will help you. Oh...the battery was "charged" so the plane will become lighter as the battery discharges .
I am nearly ready with another little Bomber so we will see what this one weighs and how it does.

We flew the Bomber today. There was a rare thermal in this part of Indiana and the little Bomber got very, very high and stayed up there with the power off. As a matter of fact, Richard was about ready to apply power and a lot of "down" to get it back. We have not decided on the best battery size yet, overall lighter would certainly be nice and I am wondering how a 2s lipo would do as opposed to a 3. It might take it a bit longer to gain altitude but other than that I dont know. I'd love to see that video!

Okay, finished my Lanzo Bomber. Used white 6mm depron and colored packing tape for the limited graphics. Power is your basic 24gm blue wonder type outrunner, a 30A esp (overkill, but Ihad it lying around) and a1000 mAh 3s LiPo. Cg ends up right where it should be, in the center of the wing. I was going to use Spektrum 2.4 but only have a park flyer RX and they have limited range. I KNOW this bomber will get higher than 1000 ft so am using a small HiTec RX with 5000 ft range. Maiden will be tomorrow weather permitting but no anxiety here, this thing will fly! Here's a couple of photos and thanks again to Crash for his work on setting up the cutting codes for this little plane. Thanks Crash!

Oh...all up weight is between 14 and 15 ounces.

I'll bet it's just nose-heavy, and it takes a lot of up elevator to keep it level under power. Try shifting the CG back about 1/2 inch and try it again. Or shift it only 1/4"back and expect to move it back more, after you fly it again.
It sure looks good, anyway.

 

66tbird - saw bits and pieces of your video and it looks like the little bomber flys pretty good. I can see what you are talking about insofar as glide ratio goes. I will see what mine does tomorrow. I never really looked at it this way because when we fly old timers we climb them very high and then look around for some "lift" somewhere. It is possible that mine will sink as fast as yours at lower altitudes but I have not flown one around like that. Maybe I will find there is a need for some improvements to get a little (or a lot) more lift. I guess I am just used to flat wing foamies and am getting what I expect. If I get the chance I will get someone to get a video of what mine does. Oh...I did not know noisy motors were last leg motors. All of mine sound that way. I thought that was normal too
Thanks for the compliment on my Bomber. It looks okay now but hangar rash will take its toll in short time (if sudden impact doesn't).

66tbird...Update...Maidened the little Bomber this morning. The wind was a little fickle, but the Bomber handled it well and climed like crazy. After flying it, I agree, closer to the ground it will sink pretty quickly when the power is cut. This could be a design flaw or it could be characteristic of flat wing foam planes. I am not sure the KF doublers are doing their job but I have no complaints as this is a fun-to-fly little airplane. Need a lawn chair though as stiff necks are part of the event. It does better with a lighter battery but that can create balance issues. I would rather have extra weight as a battery than dead weight such as lead. Overall I am happy with it and will enjoy it. As Crash set it up, it cuts out nicely and goes together straight and easy. If you do the 50 percent KF thing, let me know how it does. If it is an improvement somebody can modify the cut file to made the parts a little larger. I am on dial up, so catching all of your video is rough. I missed the landing and the second half.

Thanks for your interest in the Bomber.

I hear you on the 15' runway! Funny! Mine has LG, quite long and "springy" so it lands a little bouncy. It glides in nice and a little headwind would be welcome here I think. Overall, a fun little airplane to fly if you have a lawn chair with you. It will climb pretty high. I shut the motor down the other day and had some winds up high and it just stayed up there so I flew for about 15 minutes or so. In any case, it's a keeper. I appreciate your feedback on this plane. Maybe I can get someone to alter the Phlatcode to cut the doubler a little larger to make it 50 percent. If I get that done, I will build another and see how it does. Have a great week-end!
