You guys got us up to #38 on trending last week! Let’s go for top 20 this time! So far this video is already out performing the last! Let’s go thank you guys so much for your support on this series! Every like, comment and share helps us get closer and closer to that goal!

Pssssssst...........Invite thee awesome Sam Pilgrim to your place, and make an episode. He's in Vancouver right now, for a month. Act quick. You guys can find a lot of each others subscribers. You're both at the same level, on KZbin. Sam's a really great guy, and he won't be afraid to ride ANY of your machines.

[@markpeterson8978]

Great job on the mini-jetboat and on everything you guys do. Weird question, in the video there is a beautiful shot of the wind blowing through the trees on the property with the tree house. My question is what is it like up in the treehouse in wind like that? It must be moving around a bunch. It would be wicked cool if you got a shot from the treehouse in the wind. Keep up the Awesomeness and Cheers! \m/,

[@rexsterlingbuchanan2929]

I kind of quit watching your videos for a while after like last year or the year before that when you guys went on the Overland trip and your third person can't remember his name started destroying everybody's Vehicles out in the middle of nowhere. I mean how disrespectful is that even though somebody says yeah jump on it give it hell oh, you are still in the middle of nowhere with no way to repair any of the damages that your third person would have done. And yet he still decided to get on there and tear up if I remember right to people's equipment that wasn't even his own. So I have been checking in on your videos because I like your content and notice you have a new guy. Hopefully this new guy is not as disrespectful to other people's property as your last guy was. Hopefully I'm not going crazy and talking crap and it's still the same guy LOL but I'm pretty sure just putting a mustache on the old guy would not make him a different person hahahahaha. So as long as content keeps going towards the creation side and not towards destroying other people's property in the middle of nowhere I am all!

It seems like the trim level is pointing the nose up a little too high-- so it's constantly wanting put "pop a wheelie" and jump out of the water when you try to go fast. I'm not sure if that's adjustable or not on this thing.

[@rsharney1111]

Bro, order a vtx and maybe even a camera. The water shorts vtxs out instantly and water marks on your sensor are a pain to clean off. Idk if your running digital or analog, but I'm only speaking from analog xp. So many tiny whoops and micros lost to neighborhood pools and things.

maybe put in silica gel, because it can take way more water from the air than rice. hope you´ll get it working

This is an amazing build to watch but word of advice, waverunners suck up around a 3x3 area in the water and do not take kindly to shallow waters so it is suggested that you push it out farther before starting. Love the videos though and I look forward to the next project!!

A tip for when your drone ends up under water, unplug it before you take it out of the water. It greatly increases the chance of the components not burning out.

[@fluiditynz]

That's pretty flippin good. I think you need to smooth the insides of the intake a bit more where there are still angular transitions but you will need some rear anti-wheelie plates first. Out a bit from the back but not too much area.

[@dwdodgelover]

"I'm going to smooth this out and polish it with the die grinder" Immediately proceeds to use the 4" death wheel 🤣 Amazing stuff as always bois!

[@Woodman486]

This thing turned out pretty rad man! One thing I see when you get on the throttle the bow bounces because the pump coming out of water. I used to work Chris Hagest the designer and manufacturer of the ProForce hull, one thing I learned from him to counter that nose bounce it to extend the ride plate, the purple plate you reinforced, it essentially give the boat extra length to balance and plane on. Awesome work on the intake grate and pump stuffer, making that intake as smooth as possible! Awesome build man

[@elicarter1356]

Also with my experience with stand up skis, top loader grates loooove to porpoise on flat water. They kinda suck in anything but super chop or surf

cant be too sealed motors gotta breathe! perhaps copying or getting a 750sx snorkel/intake to put up on the bow would be wise. then you can seal it all you want, and the faster it goes the more air it gets if its done right.
