I have looked at the Hacker look-alikes on HobbyKing but was worried about the comments about dependability and the real ones are above my pocketbook. Man, if they even come close to your experience they would be great motors. They are only rated for about a pound thrust. I have a 3.5 oz ($35) and a 8.5 oz ($200) camera Im considering but want to get real confident with the plane before I try them as I will be photographing in an area where retrieval from mistakes will be nearly impossible. I guess your motor to be the 20-22L. I might have to try one of those.
Sorry about the thumb thing-it is a constant factor with my flying/crashing. I'm really good at it!

I hope so I kinda ordered it already, lol.
Let me know how that motor turns out. The power is fine. I have similar but at only half the weight. I has trouble balancing on cg so this motor would be better.

An experiment on different monobloc material. I laminated 4 layers of polyolefin foam, the camping mattress material, with 3M77 contact cement. Here is the result. An almost indestructible and yet flexible monobloc.

Without completely cutting out the voids it is heavier. .4 oz for the pink foam and .7 oz for the polyolefin. I'll compare them when they are comparably finished.

A little extra weight might not be so bad anyhow as these can come out a little tail heavy

BBAP1 Flies!!


Well, I can now report IT FLIES!!

Quite nicely I might add. I put all electronics in very front and battery (3 cell 1300) in front under the wing and it is about right. It leaped off the rough field and the O-ring broke on first flight about 5 off the ground
The plane glided nicely to the field.

I tried it with a 2 cell but it would not taxi and take off might be strong enough to hand launch but would be marginal at that. It will be a 3 cell plane. Great power with 3 climbs at throttle - cruses at less. It got a little ugly a couple times but probably me fooling with flaps/rudder/stuff. It is a smooth flying, SLOW flying, stable craft. I think as I get used to it, it will be just what I will need for a camera. I think there is plenty of power to carry the light one and maybe the heavy one as well. Ill have to rig them to take snapshots but can just turn thee video on and let it run. It was cold this morning (28 deg f and still air) so I only did about 5-10 min and then went on to work satisfied. Ill probably change from flaperons to ailerons. More testing later . . .

True. This is just an experiment. I have two or three BBs cut and thought I would try something different. This stuff is really tough, flexible, and shock absorbent. Amazing material. Picked up one of those camper mattresses from Walmart and just cut pieces then laminate them with 3M77. I think it has great potential for building airplanes.

Congratulations to Old Builder!

Did you use the GWS EP-1147 (11 x 4.7 slow fly) for both the 2S and 3S? If so I'd guess you would have had about 200 full throttle Watts on the 3S. But throttled back you were probably cruising around at 50-75 Watts.

Did you get a finished weight on that? Like ready to fly?
