I wonder about impeller for torque roll? does anyone know if the physics meaningfully change when using an jet?
For rough conditions another track to study is to carry weight.
Takuma etow was 75kg, at first I thought it was a bit silly for transportation.
BUT for sure the weight is your best friend to sail in wind chop for those who never have clean conditions.
Long time ago I was planning to design an epoxy hull with areas inside to add seawater or sandbags just before launching the device.

Our Boogie does handle a bit better with dual batteries in rough water (+15kg), seems more planted and less jumpy. The down sides are that energy consumption increases, and it doesnāt self right as easily.

Hey guys, I am attracted to the single motor pivot set up - does anyone know where I can buy a motor that pivots? Flipsky? surely this would be cheaper than building a dual motor setup?

way way cool design ideas guysā¦ my own build stalled soo many times with the torque roll problem till i went to twin counter rotating inline motorsā¦
whike the twin inkine design worked really well - ive een back at it messing around with singles tomincrease range / reduce power consumptionā¦

been thinking the same thingā¦
im back working on single motor set uos againā¦
ive put the motor right backnon the hull the prop itself is just 160mm from the tail.
im shortening the motor pod next - and angling the motor down 5 degrees -
the jets from what i can learn need to be sitting right at the water surfaceā¦ thats going to create spray
(and probably be noisy)ā¦ But im keen to test itā¦ i asked Flioski for a motor to test and oublish results but they were t interested ā¦ with that lack of confidence ive dropped it
Hello boogie riders,
I use FD clone prop since a while and I have to say that there are perfect except the fact that a foldable blade retracts when turning the boogie with steering toggle and doesnāt deploy perfectly.
Is someone motivated to create a prop file with fixed FD designed blades for 63mm outrunners and inrunners ?
This thin blades are very good for thrust, consumption and avoiding ventilation on choppy waters.
FD finally released a kind of @Strongarm mini pod so donāt be guilty 
Blades scan in PM if interested

I made it a long time ago, but havenāt tested it.
I started to doubt whether this was a good idea and whether it wouldnāt be easier to make removable inserts that hold the blades in place.
Anyone using FD props on a dual motor differential steering setup? given they arenāt mirrored, how do you avoid torque issues?
Itās probably better to have individual blades and sandwich them between a two piece hub so that they cannot close?
I used a 3D print slicer software to mirror before sending it off for 3D aluminium printing. 3 original, 3 mirrored.

I can say slightly longer foil drive props worked with my boogie with less cavitation and better top speed but folders would cause boogie to slightly lock into turn after steering. But my props blew apart after 20mins use.
Today I went out with brand new Kparts 3bladed props and one of the motor housings flew off. Iāve been having non stop dramas with the bearings on my motors. After todayās incident Iām going to change to fully sealed maytech 62161 motors does anyone have a prop design to suit these motors preferably Aluminium or nylon?
I will stick to 160amp speedies yet
I feel your pain with fixed props. On my first outing with my v3 tow boogie I went out with a fixed 3 blade prop on the two 6384 motors. Performance was great but I lost both my motor cans and props. In hindsight I guess it is to be expected with the circle clips removed for easy maintenance as the boogie has a lot of momentum and mass and when it stops suddenly, the force exceeds the magnetic force holding on the motor cans.
Iāve since switched back to folding props and these have been fine as they will collapse in the same situation and the magnetic hold is enough to keep them on. Top end performance is not as good though which makes me want to find a solution. Iām happy with the 6384 motors generally, especially the value for money but would like to try fixed props again.
Is there a way to hold the motor cans on without fiddly spacers and circle? I can use them again but maintaining the cheap motors with a fresh water rinse etc becomes a pain.
I did have the hard brake on so maybe thatās whatās happened. Anyway Iām not investing any more money and time on these motors the conditions are to harsh so sealed 65162 will be better option but only if I can get props for them counter rotating ones . AI has said to go with 155mm diameter with a 160 pitch 20 to 25% blade skew and 10 to 15% blade rake.
I never had any issues with the cheap motors and folding props (alu). Only using them in seawater.
I just spray a bit water on the stator and rinse the rotor.
And then dry both immediately.
Not really getting the stearing issues mentioned.
Do you try differential steering under load?
For simple non loaded stearing I never had a problem.
For general design - what was holding me back was weight.
I wanted a lightweight system so make in easy to carry.
Now I added additional weight with battery capacity and some counter weight to balance and it works 150% as well.
I donāt have a problem with the folding props either. It is the fixed props that i had problems with. I designed a 3 blade prop which was basically the same as the same as my 3 blade aluminium folding prop when fully folded out and it ran great. Better than folding but turned out to be no good without the c clip holding the can in place.
