My standard on all my 32" foamies is the 1500Kv BW, 9 x 4.7 prop, Turnigy Plush 10A, 2S 325-450 battery.

When the BW were first introduced, the 1300Kv was the only one available and we routinely flew those on the 10x4.7 on 2S, but the torque of the 10" prop could be a problem, it was sometimes difficult to stop the roll in a hover.

For me, the 1700kv motor requires too small a prop for fun 3D. YMMV.

Build #1 (Orange/Yellow/Blue)
18.5" wingspan. 3mm EPP foam. 8.5mm brushed motor running off 1s 250mah batteries. AUW w/batt is 44g. This will barely hover at full throttle. the foam I used for it was a heavier sheet, that I believe was probably 1.9lb. I have since built another frame from lighter foam that weighs half as much. Original frame weight (pictured) is 15g. New frame (not pictured) is 7.5g. Hoping the new frame will pull vertical.

Second build is a "Skinny Yak" from 1.3lb EPP. (Blue/Green. Woo Seahawks. )
1 hxt900 servo
FRSKY 4 channel receiver
Turnigy 2204-14 motor (WOW this thing is so smooth and quiet!)
2s 450mah batteries (32g)
AUW of 165g (133g without battery)
The motor/weight combo seems just fine. Running a 9047 prop, it will pull vertical at just over half throttle (with a 2s battery at 7.4v) It was too dark to fly more with fully charged batteries. Will report back. So far very pleased!

Were these scratch built? Or from kits? If kits, what brand kits were they?

Nice paint work!

Some are scratch, some kits....

Two outfits that I know that sell these, RACores and West Michigan Park Flyers..

Both are excellent vendors...

Fancyfoam sells them too, and you can get them kitted both with and without an airfoiled wing. I have an airfoiled version, it handles wind a touch better than the flat wing planes.

Thanks!

Both of those were scratch built and painted by me. Easy enough builds for a first timer (me!) with the plans and advice available here.
