Hey Guys,
I am planning to build a Flux board as well, I can make a thread on its own but will try my luck here first.
I have the DIY deck&enclosure combo and i am planning on fitting a 12S9P p42 battery in there but I would like to retain the possibility of upgrading to 4WD in the future. As I will not want to desolder the whole battery when the time comes, i would like to build accordingly. I would like to go with dual storm cores and if possible/necessary heatsinks through the deck but don’t know the measurements plus I would like to get your opinions on the options:
My thoughts are:
In general two escs in the same chamber without heatsinks produce more heat, sure not double the amount of a single one because there is less stress on each, but it might still be a factor on long rides.
Through the deck heatsinks might noch even be necessary as shown by The Outlaw Star
A:
If I go with heatsinks, two big holes so close to each other might make the enclosure unstable
might not fit well for the storm cores
heat build-up
B:
might fit better
the usual fins on the heatsinks are oriented differently
My original plan with the C layout was weight distribution and phase wire length. But with the new information I’ve read about inductive spikes coming from long battery wires has made me reconsider to something more like option A/B. I’m not going to cut into the enclosure to have a heatsink stick out I’m likely going to design my own tray, something like what Fredric has in the latest completes, but only to add thermal mass and ensure there’s air on all sides of the esc’s. Also holding the BMS securely above the esc’s was an initial concern so this will take care of that. If temps are to high I will work out a way to do a double heatsink through the board. I’m not concerned about fin orientation. Turbulent airflow across the fins is beneficial.
Also the reason I didn’t mention D was because it actually seems harder to work with when laid out there is less room for the phase wires and battery wire having to turn them directly up against the enclosure wall. And also having the esc edge super close to the battery.
Anybody here have any idea if this deck will take Trampa trucks without too many extra holes? Pretty sure I’d need extra ones for.the spring pre compression bolts. But does the mounting pattern line up?
Pics with a ruler of the mounting holes would be sufficient! Please and thank you
Thinking of doing this as well. Looks like the base holes line up? But holes are needed for the tensioners? Can you post some close ups ? Please and thank you
lol sorry I don’t, I have matrix on my flux and trampa on my haero which already has the holes drilled in it.
If you go with the trampa barrels and flush bolts then you shouldnt have to drill the deck
I can live with that. I run my front barrels fully non pre tensioned so I probably won’t need those for now. Just something to keep them from popping out
It think the quintessece of the long battery wire thread was that you could counter the inductive spikes by running the plus and minus cables close together or even twisted/braided… Might be worth it for the aesthetics
It’s not 100% needed I have a small 10s5p Samsung 25R mobile charger that I can hook up while riding, if I need an extra 6 to 8.
one of the dudes I ride with a lot rides a 12s10p Samsung 50e lonestar and he always had a good 10 to 20% more than me after we ride. So I get anxiety from that lol.
Honestly dude I think you are fine with this - I haven’t had any heat issues since going dual unity 4wd. I didn’t have any heat issues when I ran dual TB V6 either. I only had heat probs when I ran dual focbox no heatsink. if you are worried about heat and are going to 4wd a single piece of aluminum under the stormcores should do you just fine. I haven’t seen the need for active cooling on my build at all.
I’ve done 30 miles of hard riding straight on this setup for reference.
