Hyper 8 Buggy on 6s

[bdebde]

how are temps? I have been considering going 6s on my buggy for cooler temps.

Thanks Mike, could not have made these trays without your help!

bdebde, I have only run for about 12 mins or so, but nothing was very hot. The motor was around 100f, batteries and esc were cooler. I need to get everything mounted properly and put a body on it. Then I can beat it up and let you know how it does. Considering how much I pulled from the batteries, I suspect it will run reasonably cool.

Made some al mounts for the battery tray. Used 1/4 inch al bar stock and trimmed it to fit, drilled and tapped it as well. Mounted them to the chassis using the gas tank holes. Still need to fab up an esc mount, but ran out of time.

Hey James, i've a pair of 2170mAh, 3s flightpower too, do you think i can run it in serie in a buggy with my Neu 1515, 1Y???
And what run time do you think i'll have aproximatively?


thank you

Missed this post, sorry David!

The 1515 may draw too much, what is the kv on that motor? A 1512 with kv around 1600 should be fine in a buggy with these batts.

I am very impressed with this setup, just need to get a body on her and run few packs. Plus I just bought a medusa v3 60mm 1500kv motor to test out with this setup. And I have a hacker b50 15l, and a c50 14l to try out.

Went ahead and put the medusa in the hyper8.

I will have to say that it is very powerful. It is rated at 1500kv, but puts out the same rpm and runs the same speed as the align 600l. It is rated at 1620kv and I used the same gearing. Plus it spools up faster and runs cooler too.

Ran the buggy for about 15min and temps were very good. Motor was around 130f and the batteries and esc were not much over 110f.

Had a small issue with the quark 65, it exploded. Smoke went everywhere and all of the solder melted off the board. Luckily nothing else was damaged. I guess that I overdrew the esc? It was not warm, maybe something came loose? So I replaced it with a quark 125 and it worked fine during the 15min run. I have no idea why the quark 65 let go, but it sure was cool when it puffed!

I weighed the buggy, with the batteries it weighs 3449.2 grams, and without batteries it weighs 3097.6 grams. So that is 7.6 pounds with batteries and 6.8 pounds without.
