Oooooh... That teaser at the end... I can‘t wait!

[@bossolo7582]

great boat, mr. voltage...unusually sober here, i was expecting like four motor per propeller 😅 until i watched the last seconds...ok, he's still him...

[@marxpeklegotechnicdesign3]

😁 trust me i tried. But it would barely float with 4 motors and 2 buwizz. But that wont stop me. Lets call this boat a test vehicle 😉 i will make a fast boat someday! And yes i had some buggy motors tied up in another moc. Soon i will post a video with another small update on it.

Woah very epic, I wish Lego made propellers like that

wow!!!!!!!!!!!! its so fast!!!!!!!!!!!!!!!!!!!!!!! the waves in the back are like on a real boat!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@chrissmarduksrccarcarnage4940]

I will try to build a boat with the new hulls from the 42105...

[@friedls]

Wow! Great work!

[@LucasDynamics]

Did you mesure the speed?

[@ZEROBRICKS]

Well done! Mind sharing the 3D components files?

[@marxpeklegotechnicdesign3]

I will make a short instructional video on it soon. I will put the files on thingyverse for download at the same time.

[@legolas7470]

Yes

[@legolas7470]

Are the two boat parts real Lego parts and if yes in which set do they appear? Great job know how hard it is to make a legoboat fast 👍

[@marxpeklegotechnicdesign3]

The hulls are from the 7244 set. And thanks!

Fan Question - How many Buggy Motors do you own?

[@marxpeklegotechnicdesign3]

How can i refuse a fan? 😁 18 useable ones. 2 that need revision. And 2 fake chinese.

[@jordansharwood]

@@marxpeklegotechnicdesign3 Wow that’s insane! A total of 20 genuine Buggy Motors is awesome!!! 😎🤩

[@marxpeklegotechnicdesign3]

@@jordansharwood yeah ive been actively chasing them for a few years now. But soon buwizz will release better and cheaper new versions of it. Preordered a few myself maybe more later.. if you are interested: please use my affiliate link in the description. That really helps me out as well!

[@jordansharwood]

@@marxpeklegotechnicdesign3 Very nice! And yeah I know about the BuWizz Motors in fact I’ve already got some on order! And I can’t wait to use them!

[@WilliamChanter-ee7jk]

could u put a download for the propeller in the description, id like to make it

[@marxpeklegotechnicdesign3]

[@MegaMike1]

Can you use L motors instead of the buggy motors?

[@marxpeklegotechnicdesign3]

I suppose you can, but it would need at least 6 L motors plus gearing to get the same power, and that would need more hulls to keep it floating i guess.

[@MegaMike1]

@@marxpeklegotechnicdesign3 ok I acquired 5 buggy motors for now from my racers. Can I use RC unit instead of buwizz

[@marxpeklegotechnicdesign3]

@@MegaMike1 the old rc unit can power 2 motors max. But they run off a single port and cannot be controlled separately. But it does have a built in servo you could use for a rudder for a boat. Requires a complete different design but surely doable

[@thisisaduck]

I noticed it seem to accelerate to its top speed almost instantly. I was wondering g if you could design a propeller that could enable much higher speeds and has a more gradual increase. A bit like a bike with big wheels vs one with small ones. I don’t know if you could just make the propeller bigger or longer.

[@adrian_zombturtle148]

Since it accelerates so fast I bet he could put in a gearing increase to make it faster Edit: oh sorry I forgot to press read more lol

[@marxpeklegotechnicdesign3]

You are right speed can be improved. However i made and tested 5 different props. With this prop lud. mode can trigger the protection sometimes, id like to avoid that when my boat is on a lake.. so i was carefull here not to trip it and loose connection. But yes.. i will make something faster someday.

[@thisisaduck]

@@marxpeklegotechnicdesign3 it is still very fast as is. I wish I could get my hands on props like yours. The Lego ones are a bit small and don’t work well for larger boats.

[@marxpeklegotechnicdesign3]

@@thisisaduck i will make the 3d files for them available. If you know someone with a printer you could make them yourself. I would also be glad to sell them but i fear the shipping costs will be out of proportion..

[@legolas7470]

@@marxpeklegotechnicdesign3 I nethertheless I would buy it

Max speed?
