OCTURA’S ELECTRIC FRIENDLY PROPS

The Electric Friendly Props chart is essential reading. It provides you with the props and motors used in finals competition at state and national level.

The Speed chart tells you the speed at 10% (rigger), 15% (tunnel) and 20% (mono) for each prop in the Octura range at 20,000 rpm.

The Octura Propeller Definition Table will help explain what each propeller type is best suited for.

Finally, To purchase a propeller, email your request to andrew@fastelectrics.com we can arrange delivery and payment via Paypal, money order, money transfer or cheque.

OCTURA PROPELLERS DIAMETER & PRICE x BLADES (2 & 3); PITCH RATIO (1.6 = 1600); TYPE (P,M,X,Y, 00's); NORMAL & REVERSE ROTATION (R) 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.

The Octura Propeller Definition Table
SERIES	USES	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
