The saw props have AR of 2.3 and 2.4 they have a BAR of .38 and a 23 degree rake.

Spruce and glue is coming soon enuf!

Thanks,

Here s some theory with the prop and my hand wound motor. Specifically wound in a Kv suitable for 10 s lipo in a boat.







Here is the Plot data based on the motors measured constants size type and weight:
33,940 rpm
153 amps
Pin 6.394 kilowatts
Pout 6.125 kilowatts
Run time 3.85 minutes
Est speed 90.12 mph or 145.03408 km/h
Eff. 95.80 %

Rm .oo5 Ohm
Kv 824
Io 3,27 Ampere @ 22,5 Volt einschließlich Radiallüfterlast.
Gewicht 448,8 Grammut

They are here also to put into you own calculators but here is the straight math on the motor for peak Eta....





Should be an excellent T or S sport hydro motor. It will power an 1/8th scale beautifully though not approved in a sanctioned 1/8th scale class. Its only 448 grams!

Regards,
Hubert

Tell TSDAVIS he can come here if he wants to see the high current motor rewinds in the boats!

Thank you
Hubert

90,000 RPM she has a stainless steel sleve





Thanks

My other new toy

Thanks
Hubert

10 channels of Futaba. Ordered and on the way....

And this should make for a pretty good prop at 30,000 rpm

I know you've all seen the marine vesrion. due in late this month! RIGHT???




AVAILABLE FOR PREORDER, ESTIMATED SHIP DATE: LATE AUGUST

Castle is excited to return to the boat market after a decade long hiatus. We are pleased to present the Hydra XLX2!

The Hydra XLX2 is based on our popular and powerful Mamba XLX2 ESC. We've removed the air cooled heatsink and added a watercooled heatsink. It is finished off with an aluminum top plate for a clean look. Attached to the top plate are two aluminum, water fittings for 1/8" tubing and uses standard 10-32 UNF threads; package includes optional .17" fittings.

CRYO-DRIVE™, Castle’s proprietary breakthrough technology integrates unique software and dedicated hardware to reduce heat and dramatically increase performance. Thousands of times per second, the XLX2 software minimizes the amount of time the electrical components spend generating heat. These software advancements work in parallel with an open housing design which enables increased directional airflow to cool critical components. With the combination of a new 50mm fan and forged elliptical fin heatsink, the XLX2 maximizes airflow throughout the system, taking thermal performance to a whole new level. The results are more power handling, cooler ESC temperatures and longer runtimes and for ultra-high performance.

NOTE: Due to the high power nature of the XLX2, you must use appropriately sized batteries and connectors. We recommend a minimum 150 amp connector for the Hydra XLX2; examples include Castle 6.5mm polarized, EC8 and QS8. DO NOT USE XT90, Traxxas, EC5/IC5 or any other connectors rated below 150 amps continuous.You can easily optimize the ESC for any running conditions. Create, save and download setup profiles through the Castle Link Programming Suite on your Windows™ PC, or wirelessly with the convenience of the new B-Link™ Bluetooth™ Adapter and Castle Link app for Android or iOS.

Additional tuning flexibility awaits you with on-the-fly adjustments from your transmitter via the Auxiliary wire. Simply connect the white signal wire to an open radio channel, and enable the feature in Castle Link by selecting what Auxiliary function you would like to use. Access programming parameters such as Torque Control, Max Brake or Max Throttle.
HYDRA XLX 2 FEATURES:

• Input Voltage Range 3S-8S LiPo (33.6v max)
• Sensorless, SmartSense™ and Brushed Running Modes
• Powerful Integrated 20A Peak Adjustable BEC (5.25V-8.0V)
• CRYO-DRIVE™ Technology minimizes the amount of time the ESC’s electrical components spend generating heat, resulting in improved thermal performance during partial throttle operation where the majority of driving occurs
• ESC is housed in a rugged CNC aluminum case and potted in waterproof epoxy to protect the electronics and promote efficient heat transfer
• Machined water-cooled heatsink with water fittings for 1/8" tubing.
• Compatible with S.BUS2 Telemetry Link and Futaba T4PX, T7PX and T7PXR transmitters
• Mounting holes located in bottom of aluminum case for affixing to your vehicle

• Data logging capability to capture and record performance data from your vehicle
• Auxiliary wire functionality for "on-the-fly" adjustments using your transmitter
• Audible alerts for easy diagnosis of common issues such as motor-over-temperature and low-voltage cutoff
• Convenient transmitter programming for six common adjustable settings including cutoff voltage and drag brake
• Castle Link USB programming kit (coupon included with purchase)
• Optional smartphone-based programming with the B-LINK™ Bluetooth Adapter (sold separately) and Castle Link all available on Google Play or Apple App Store)
• Proudly designed and manufactured in Olathe, KS USA and backed by Castle Creations' 1-year warranty

Hydra XLX2 ESC COMES WITH:

• Hydra XLX2 ESC
• Castle Creations Decals

• Coupon for free Castle Link USB
• Hydra XLX2 Quick Start Guide

The 10 channel Futaba was 811.00 to the door... One of the boats powered with the APD may end iup with a beta flight capable flight card for self leveling options and low pass filtering on a single layer motor for lower motor THD and noise.


The APD inverter is capable of 40 kW!! Its 20S lipo....

It cost me $1200.00

Regards
Hubert


U can never have enuf options.....

Tell TS Davis and all the advanced boaters that actually know something about mathematics physics and electronics from IMPBA and NAMBA interested I'm here with my high pitched propellors, high current motors, and inverters for the electric boats. Here we will put theory to test.

Talk is cheap....and a castle inverter will run a Plettenburg tetras with no issue!

You all probably know about this but here is the theory behind such an unlimited for those they may not know.. I think it still applies and would like to expand upon it by making the surfaces truly active .

– Integrated rate gyro, compact size, and light weight
– 3-Axis Gyro plus 3-Axis Accelerometer
– Auto recovery
– Four flight modes: (Auto recovery/Normal/AVCS/Gyro OFF)
– Supports 2 ailerons, 2 elevators and 2 rudders types

If you got 35 minutes enjoy the history and the history of the blowover!

Running a 180 MHz 32-Bit processor these will deliver maximum smoothness, unmatched linearity, with ultra-fast throttle response for unsurpassed flight control. With peak power ratings up to 30kWs, these ESCs will have no trouble powering your craft.

The APD developed (proprietary) firmware ensures unmatched low-throttle and starting characteristics. Ultra-smooth starting and ramp-up characteristics ensure your drive-train is safe. Features include PWM-frequency dithering to avoid PWM-commutation synchronisation, adaptive motor timing advance and proprietary developed Active Phase-Current De-magnetisation (APCD). APCD along with Synchronous rectification ensure maximum ESC efficiency is achieved.

Designed and manufactured in Australia using only the highest quality components, ensuring no sacrifice in reliability.

Aerospace grade ceramic capacitor bank for lowest possible ESR and maximum reliability, no more dried up electrolytic failures!

Multiple operation modes:

This is not a sea king 180 it is the lightest most power dense and advanced hobby inverter in the world.

Im starting out with a 1/8 in wire drive setup but I have the plans and procedure from Jimmy for the ball pin universal cutting tool that can withstand the torque. These can be turned, with this tool. in O-1 tool steel.

The wire is a very nice manufactured piece setup for a 1/4 inch strut with a stepped down to .187 for the prop bores I'm running. I also keep an assortment of K&S scratchbuilt 1/8th inch wire drive stock on hand. Now that i have the lathe turning the ferrules is no issue.
