配置嘛就是便宜！:em17:
淘X网购的无刷电机2415-7T 3850KV 、40A的电调、9G舵机、暂时用个430二叶胶桨、
还用个郁闷的怀孕锂电

还有用了个很坚的老虎轴系舵系:em15:

換個60A電調..試試432的槳

手工不是我看见最精的，但绝对是有想法的。顶你。

请问LZ:你的虾用的碳杆啥规格?管子还是棒?

想试个430三叶胶桨如何?

:loveliness::em00: ，反正便宜有便宜的玩法，贵有贵的玩法，平时拿它来娱乐娱乐也是值得的:em15: 。

管子长30CM，可以用碳杆或玻杆，甚至可以用废渔竿，用直径6MM或8MM都可以，我就用了6MM的玻杆:em19: 。

嗯…三叶比大尺寸效率还要高一点…但电流可能稍大一些

玩蝦一般用二叶桨,
可试用同一直径但螺距大一点的和金钃桨(如octura的1630/2叶)效果会好多了:loveliness:

:em15: 哇！大师也来了！
金属桨效果要比胶桨好点，
如果螺距大点，电调的电流也就大点，发热量也会大了，不知我的40A电调受唔受到？
可唔可以将432二叶胶桨DIY成直径30MM的半浸桨用呢？貌似螺距会大点？

螺距(Picth)就是推水角度,不同直径:em19:
上些不同Picth的桨型你看!
其实沒可能將一些幾十年來船桨变化出來的桨型一一導出來讨論的,但其螺距和主力用途一般廠家都会有分類的.

The Octura Propeller Definition Table
SERIES螺距型号	USES可用船型	CHARACTERISTICS	NOTES
0900	Scale boats. Submerged drive	Low pitch prop. Blade area loaded toward the tip of the blade	0937/3 has 1/8" shaft. Electric scale – e.g. 40" Dumas ChrisCraft w/700bb & 0937/3
1200	Submerged, electric, heavy hull
1300	3.5cc mono. Submerged drive	Low lift. Blade area loaded toward the tip of the blade	Nitro
1400	Surface drive	Medium levels of lift. Blade area weighted toward the tip of the blade.	Nitro Suits heavier hulls.
X400	General purpose prop mono tunnel hydro	Low lift Light loading at the tip of the blade	.125" shaft for DD 05’s. To 47mm in geared/large electrics. The mono/tunnel prop. Also on hydros
X600	General purpose mono tunnel hydro	Tip squared to increase loading across the outer blade	As for X400’s
M-Series	General purpose lighter running hulls	The x series with a trimmed tongue	47mm popular with Aveox 1412 & 12 cells
Y series	As for x series, monos, tunnels	The x-series with 10% extra pitch through the blade	35mm on neodymium motors 6 cells
1500	A do-it-yourself prop	Low lift/high rake prop. Large blade area. Limited diameters. Designed to be customised	A rarity in electrics
1600/1800	Riggers, hydros	A medium-high lift prop. 1800 has higher pitch ratio	Mainly nitro
1700, 1.25 1.6, 1.8, 2.0, 2.4	Outboard riggers, hydros, 4 cell hydros	Highest levels of lift in Octura range No rake on trailing edge	1/8" shaft for direct drive electrics, Larger sizes on geared 8 cell plus hydros. Popular for Saw’s
P-series	Riggers hydros	A 1700 with less lift due to increased rake in trailing edge	P747 popular for 12 cells
1900./2200	Riggers Hydros	Medium lift. Offset blades.	Gear driven – high torque motors - rare
V900	Outrigger/hydro – SAW	Medium lift Very low loading at the tip of the blade	Suited to light boats and high revving motors. 3 blades provide adequate area for thrust Popular at saw particularly with geared or neodymium magnet motors
2000/2100	Outrigger/hydro	High lift props Originally designed for geared electrics	1/8" shafts on 2132 and 2135 for direct drive car motors. Used successfully in 4 cell SAW

以方便大约计算出船速來.

OCTURA                   PROPELLER SPEED AT 20,000 RPM 10%                   SLIP/RIGGER (ESTIMATED)
                  Props                   27 to 35 mm take a 0.125" shaft.  Props 36 to 62                   mm take a 0.187" shaft with exception of the 0937/3                   which takes a 0.125" shaft.  Props 62 to 82mm                   diameter take a 0.250" shaft.

OCTURA                   PROPELLER SPEED AT 20,000 RPM 15%                   SLIP/TUNNEL (ESTIMATED)
                  Props                   27 to 35 mm take a 0.125" shaft.  Props 36 to 62                   mm take a 0.187" shaft with exception of the 0937/3                   which takes a 0.125" shaft.  Props 62 to 82mm                   diameter take a 0.250" shaft.

OCTURA                   PROPELLER SPEED AT 20,000 RPM 20%                   SLIP/MONO (ESTIMATED)
Props 27 to 35 mm take a                   0.125" shaft.  Props 36 to 62 mm take a                   0.187" shaft with exception of the 0937/3 which takes                   a 0.125" shaft.  Props 62 to 82mm diameter take                   a 0.250" shaft.

我的快速计算方式;
PICTH(螺距)乘以RPM(轉速)X60(分钟)除以63360FT(英呎)再減去?%水阻=MPH英里時速(公里自己再換算)
