![]() The Happymodel snapper7 is an excellent brushless whoop, certainly the favourite I've come across as you'll see in my review. However since URUAV UR65 was released I have lightweight envy - it's no secret that I love lightweight quads for increased agility and longer flightimes e.g. lightweight 5" floss 2 racer, lightweight komori 3", lightweight leader 2.5", lightweight 2" 2s etc. It's good then that there is a new frame available called the BWhoop75 from Bangood. It's less than $4 and weighs 4g less than the standard snapper7 frame. Additionally it is made out of a flexible plastic that should hopefully be more robust - I have heard complaints of people bending aluminium prop gaurds. You can just buy the UR65 frame which is 1g lighter than the BWhoop frame again but I prefer the 40mm props of the 75 frame over the 31mm props on the 65mm frame. It was a bit disappointing when the frame turned up a bit deformed from damage in transit but with a heatgun it was easy to get the shape back. It's still a pretty marginal frame (check out the prop duct strut orientation below - not even) but I was determined to go ahead. The swap over was really simple given the awesome AIO crazybee board and plug in motors. It was certainly relieving finding out that the frame was branded HappyModel as well so everything is a perfect fit. See my gallery below for pics during install. The only hardware I needed that was not included was 2 self tapping screws that are typically used to hold the main board down in a chinese whoop clone. These were used to hold the canopy down after giving it a minor trim (again, see below). For final weight you can see I was able to drop nearly 4g which is huge on these tiny quads with a relatively low power to weight ratio. No it's not as light as the UR65 but it does have higher kV motors (19000kV vs 17000kV) and larger props which make for better performance. It seems to be standing up to crashed pretty well so far but I will report back on longer term performance. I can still fly outdoors on a reasonably calm day but with the lighter frame it feels more responsive with more pop and can get around corners more quickly without blowing out. A definite improvement and a great upgrade so far for only $4.

Very nice, Thanks! I think I'll do something like this to mine. Any idea where to get those tiny nuts that hold the canopy on the snapper7?

Hey Chris. They are an M2 nylon nut. Most hobbystores physical and online should carry but here is a BG link if you need https://www.banggood.com/custlink/vvvKy9viDS
