JDubs Dual Motor Tow Boogie

Made a smaller board setup. Motors much closer together and it actually worked really well. It was choppy this morning, so one of my bigger boards would have done much better, but this is a nice smaller setup. Made a new motor pod that is much better. Still tweaking it to optimize.

Love it! This is encouraging. I’m interested in building a small setup, though I had previously read somewhere that they didn’t function well. I’m happy to trade off some stabillity for a more compact setup. I’m encouraged to give it a try.

@Jesserosco …how far apart did you put your motors on this version ?..looks.good.

About 7 1/2 inches apart.

Small single motor tow boogies don’t work well. Dual motors with counter rotating props should be possible to make a lot smaller.

The small boards work great, but of all my boards the CBC Sushi 5’ 8” is by far the best for all conditions.

This is good feedback to know. Nose rocker seems quite critical and the Sushi has a good amount. I’m using a 4’6 inch soft top (similar if not identical to @Etiennebzh Wave Power Softy 4’6) with very little rocker, and on first testing this weekend, had to give it a really good burst on startup to get the nose up, otherwise it would just bog. I might try the pool noodle bow like @Strongarm used on his original Boogie, and also keep an eye out for something with more nose rocker.

I tried this stuff and it works good on my 48 inch boogie

@Jesserosco Looks like you might have bent the nose up on your Sushi board in these images, was that intentional or did you hit a wall at speed by mistake? :sweat_smile:

I totally agree with having more rocker. I wonder if I could heat the nose up and bend it.

It was like that. Used board

I never tried but in reshaping your nose, maybe cut some thin v slot relief lines across width of the nose where adhesive can be applied to help keep new rocker shape after it cools

I’ve made a lot of changes to my boogies and will post some updates when I can get some pictures together, but basically I found the 4mm bullet connectors with 12 awg wire inside my box for the motor wires were getting way too toasty for my comfort. The heat deformed some PC and ASA spacers I made for the connection point and also melted some of the foam inside my box. I am swapping all my connections for 8mm and using 10awg for the motors. I’ve already swapped one over and it is a lot less heat. I made some new motor pods that require modifying the front of the Ali 6384, but are much easier to run the wires and the pod is much stronger. I changed the thru box connectors and do not use threads anymore to secure them like the ones I modified using @hangloose. I use a little dielectric grease to seal the connection and have had great success.

I have also found putting the motors as close together as possible is a great improvement. It still steers great, but is so much more stabile in the roll axis, especially during turns.

I did wanna give a big shoutout to the APD speed controllers. They work phenomenal and their customer support is the best. I actually had one explode… haven’t figure out why, but it appears a capacitor decided to self detonate. It happened when it wasn’t under any load and I’ve been running them 3-4 times a week for over 6 months. I contacted APD with pics to see what they thought and they didn’t know exactly, just speculation, but have sent a new one under warranty. I bought a few more to convert all my boogies and highly recommend any of their products if you are looking for a non-VESC based controller. A little pricier, but much better quality.

Great update. It sounds like your boogies are getting very refined now. It would be great to see some photos when you have the time.

I see there are a few different models. What APD speed controller do you use?

Fantastic work Jesse. The video popped up in my feed before I saw your post. Watched it straight away. It’s amazing how refined this boogie is now looking. Well done. It’s an awesome machine.

It’s definitely come a long way from the first one. I have a ton of great footage using it that I need to edit down… hopefully soon.

Link for antenna please :slight_smile: I don’t know what ‘NRF Board’ is but if I see the link maybe it will make more sense and would include an adapter for the IPEX connection?

I got the mini with antennae. It’s the NRF module that the BREmote uses.

I just found this on AliExpress: $3.57 | GT-24 Wireless Module 2.4G NRF24L01+PA+LNA With Antenna Industrial Grade Digital Transmission 1100M Distance SMD/DIP/Mini
