38mm diameter alloy spinner for folding prop, comes with adapters for 2.3mm, 3mm & 3.17mm motor shafts.
Prop Mount Bolts: 2.2mm
Excellent quality spinner, perfectly balanced. Gave it 4 stars because I purchased this to fit a 3.17mm motor shaft, the included 3.17mm adapter was infact 4mmNot so nice like the other spinners from HK.
The two bolts are a little short and 2.4 mm diameter for prop blades.
Luckily I have a lathe to make the needed parts ;-)
EsEste spinner muito bom. Tem uma boa fixao e proteo aerodinamica. Achei um pouco pesadinho e seu acabamento poderia ser melhor.Very good value for money. This is a nicely machined piece. Mine arrived as pictured except the center screw is black and takes a small hex wrench (wish I could tell the size) rather than a philips head screwdriver. Fits the HK TGS 10x6 precision folding prop.
