"I may not have gone where I intended to go, but I think I have ended up where I needed to be."
Quote from Douglas Adams, The Long Dark Tea-Time of the Soul
We added a second, stock, new Pro Boat Stealthwake in the Summer of 2021
Be sure to check out the dedicated, original Stealthwake #1 page for different upgrades and changes
You will find videos and information on the upgrades here. For many more videos, check out our YouTube channel: Handful Of Hobbies (formerly Generation of Gaming) (also linked above)
Below are videos and pictures of the upgrades
After the Prop Test results chart is the list of components and upgrades specific to Stealthwake #2
This first list of videos are specifically related to the upgrades. They are posted in chronological order with the newest upgrades at the top of the list.
If you want to see details of the upgrades with tons of pictures, measurements and test results, you can download the full document in PDF format. You will need a PDF viewer to see the file.

Suggested upgrade order for a Stealthwake:
Continue below to see the items we used on our Stealthwake #2 including where we bought them and the actual component numbers.
A 2-cell (2S) Lithium Polymer (LiPo) battery
The higher the mAh, the longer the run time but the heavier the battery
The "C" rating should be as high as you can afford. It's a 'measure' of how quickly the battery can dump 'juice' to the ESC and motor
Brushless Upgrade
Brushless Motor with a KV rating to stay between 25,000 and 30,000 RPM (KV x VOLTS = RPM)
4000KV or less if only using a 6 cell, 7.2 volt NiMh battery or 2-cell, 7.4 volt LiPo (4000KV x 7.4V = 29,600rpm)
2700KV or less if using a 3-cell, 11.1 volt LiPo (2700KV x 11.1V = 29,970rpm) (also works well with 2-cell LiPo = 19,980rpm)
Brushless ESC (absolute minimum: 60 Amp, recommended is 90 Amp or higher)
Motor to prop shaft coupler if the motor isn't 3mm or 1/8" motor shaft
Longer aluminum rudder
The added 1-1/4" of rudder in the water dramatically improved control of the boat
See the section "Fiberglass ABS boat hulls" in my Other R/C Info page for more details on applying fiberglass to the ABS hull.
Wire Drive system to replace the stock prop shaft and stuffing tube
Wire drive assembly with 3/16" prop shaft - .062" or .078" wire
Motor to wire coupler
Brass tube for stuffing tube
New prop(s)
Trim tabs
Turn fins
Additional components at any time if desired (optional): water line inlet and outlet, tow hook, stickers, etc.
Items we purchased to upgrade our Stealthwake:
Items below are listed in the same order as the "Suggested upgrade order" above.
Most items below are from Offshore Electrics
And no, we do not get anything for promoting Offshore Electrics (OSE), or anyone else; no free product, no kick-backs, etc.
OSE is a trusted seller who has pretty much everything you need for your R/C boat, primarily fast electrics (FE). And Steven is great at helping set up your boat. He helped me with my Invincible Razor build.
And the OSE forum is an outstanding source of information from other FE R/C boaters.
Dynamite Reaction 2S (7.4V) 5000mAh 30C Hard Case LiPo Battery w/EC3 plug from HobbyTown
Brushless motor & ESC components:
Leopard 3650 2750KV 5D with 6mm bullets : leo-3650
