With the very good support from Jens (Kappel – nowind in this board) I was able to build my Trampa E-Mountainboard within the last few days.
My setup:
35º HOLYPRO TRAMPA deck (16ply)
VERTIGO Trucks
SUPERSTAR Wheels
RATCHET Bindings
YELLOW DAMPA’s
TITANIUM kingpin
Heel Straps
2x Turnigy SK3 6374 192KV Motors
2x Roxxy 9120 ESC
Mini Remote from Hobbytech
YEP 12S SBEC from Hobbyking
E-TOXX Chain drive (gear ratio 1:6)
6S / 12S Turnigy Lipo (4000 – 4500 mAh)
Weight: 10,9kg without Lipo (12,2 kg with 2 6S 4000mAh Turnigy Packs)
Since I am new to riding a Mountainboard (I started with a Mobo 800 this year) I am still riding on 6S with the setup. This leads to a VMax of 26,5 km/h on the straight and I habe a range of est. 8 km for 2 6S packs in parallel. (in sum 8000mAh, rest voltage 3,7V per cell)).
I finished my build last week and rode it for 50km by now. Big fun!! Thanks to Jens for the parts and the very good support during the selection of parts as well as during the building!!
In the meantime I added an Antispark device into my power contacts by soldering in two 33 Ohm Resistors in Row (see pictures), because the spark while connecting the 12s Lipo was a little bit scaring.
Further more I added in sum 5 low ESR Capacitors 63V in order to protect my ESCs against Voltage spikes.
Rear axle seems a bit loose on high speed or acceleration… Do you screwed in the adjusters a bit?
It improves the stability a lot because the “dampa” is then in contact with springplate.
