The Happymodel Snapper6 toothpick quad was fun but its power is lacking and the frame has been abused more times than I care to admit. With the Mobula 7 and 8 out also running a similar board with a lower amp rating meant it's possible to use the newest generation motors on the Snapper6 board. So that's exactly what I did.

3D printed 68mm custom frame
Happymodel RS0802 / 20,000KV motors
Gemfan 1610 - 40mm props
450mAh 40-90c 1S lipo
Stock Snapper6 control board / camera (for now..)

The frame is printed in PLA+ and is 2mm thick with propeller guards to boot. This very solid rigid frame is only 6 grams.

/theme/snapper6/2-generations-view-frame-evolution-fatedev

My version history of frame designs from the stock replacement I made a while ago to a more compact version and finally the Mk3 68mm frame, the most compact frame that is both extremely durable and light.

/theme/snapper6/3-new-motors-fitted-fatedev

With motors on and tri-blade propellers comes in at 16g, but these are not the correct propellers for performance.

/theme/snapper6/4-snapper6-all-electronics-fitted-fatedev

25.5g now with the original Snapper6 control board and camera / VTX installed.

/theme/snapper6/5-half-gram-lipo-caddy-fatedev

These 1s lipo mounts come in at little under half a gram and are way better than an elastic band or similar.

/theme/snapper6/6-26g-with-tri-props-fatedev

Final benchmark of 26g but again, not the correct propellers.

/theme/snapper6/7-snapper6-3d-printed-frame-bottom-fatedev

You can see how the lipo mounts just CA glue in place and will fit 450/550 and even 650mAh 1s.

/theme/snapper6/8-steel-plate-prop-removal-tools-fatedev

The original Snapper propeller removal tools are not super and broke. I got some 0.75mm shim stock steel metal plate and fabricated my own. Much stronger and a couple for friends.

/theme/snapper6/9-40mm-gemfan-props-fitted-fatedev

Finally the Gemfan 1610 propellers arrive. Now we can really test.

/theme/snapper6/10-25g-gemfans-ready-fatedev

The new props also drop the weight by 1g so now its 25g minus lipo.

/theme/snapper6/11-snapper6-upgrade-37g-auw-fatedev

Ready to Fly - 37.5g with a 450mAh 1S. Kept well below the 40g mark of the Mobula 7/8 with the same motors, smaller more agile frame. This will put the stock Snapper6 to absolute shame now :)
