This my first build topic. I took me almost 2 years to built this MTB haha.
I made a lot of changes during the build. From undertray to toptray battery, 6374 to 6384 motors. Trampa to MBS trucks. Belt drive to geardrive. Trampa bindings to MBS and so on.
Last weekend was my first drive ever on a MTB/ pneumatics. WOW! this completely different.
I really enjoyed shredding over pavement, dirt, grass, hills. etc… I’m quite surprised how fast I got used to stay in balance, drifting into corners, going up hills.
I really like this new way of boarding
Anyhow this is the list.
Trampa E-deck
Trampa 8’Superstar wheel with Innova Tyres
MBS Matrix II trucks with metal base plate, -5 degree Rear Red/ Front Yellow
TPU bottom rear cable channnel with side entry for motor connections
TPU bottom front cable channel
TPU -5 degree dewedge rear truck
TPU 5mm front riser
PLA TOP front & rear cable channel covers
PLA 6mm spacer monsterbox
PLA Backplane Escape Monterbox V2
PLA Lighting bracket front
PLA Lighting bracket rear
PLA 6mm hole caps Trampa deck
PLA "in da loop"key from Dani
Things to
Find a name for the board
Currently working on fenders/ wheel guards for the wheels
Griptape is not sticking properly to TPU concave pads. Redesigning the pads to get rid of the griptape.
Would prefer to have some more low end torque. Maybe I can increase batt current a little bit but need to monitor temperature of the batt better. Currently after hard pushing already 47 degrees
This is done by trampa. To be honest I would only purchase it as a complete board.
I expected a top finished product but still had to do some quality finish/ improvements/ tinkering etc. which I didn;t expect for the pricetag/ trampa brand.
Yes, defiantly depends on the batch.
I would non the less always upgrade the motors before use. When the magnets first broken it’s a pain to change them.
yes I know… haha. We will see how it goes. I’m not in a rush atm.
I thought about the encoders. But then I have to modify my gearbox probably and to get a good signal, cable need to be short as possible, no extra jst connectors int between, get rid of the trampa sensor pcb etc. This means I need to modify quite bit in the cable channel. And than still all cables are running parallel with the high inductance motor cables. I’m not sure if I can get clean signal vs. benefits.
Had my first crash on my MTB this weekend. My front lifted unexpected at around 30km/u, lost a bit of balance, when the front touched the ground again the pressure on left wheel was much higher. Massive wobble and crashed onto the pavement with my board strapped to my feet… Impact was quite hard. Overstretched some muscles in my legs, arm towards my neck. Almost now road rash since I was wearing protection.
Stupid lesson learned. Made too many changes at once:
Increased motor current from 75 to 90
Increased battery current from 80 to 120
Increased PPM positive ramping time from 0.3 to 0.2
Loosened rear shock blocks at bit
The board was much more aggressive than expected while rear the was to loose. Basically recipe for disaster. Especially since I was pushing the board hard last time without any issue I had a lot of confidence from the start.
I first need to recover a few days before I can get back on the board…
Glad you ok more or less!
Did you run the 120A battery max on one vesc or is it the value for both together?
Edit: just went through your thread and realized that you want to upgrade to a bigger motor when you even didn’t max out the ones you have? I think the thing which limits your torque is not the motor, but the battery and the settings. With the 1:5 gear drive at 170kV with 80A bat Max and 90A motor max, positive ramping at 0.1sec and throttle curve at 15% you should take off each time you pull the trigger
Maybe you are right…
I lost a few recordings. But looking at this one. My motors are maxing out most of the time. (old settings)
In grass I can power drift, but it’s not eating grass like…(i don’t know)
Also going up steep hills with speed, at the end i’m loosing rpm/torque…
Since motors are maxing out, I thought I need bigger motors. Ordered them and then changed the settings and was surprised how it’s changed. Since I only drove to 500mtrs. Never reached the grass I still need to see if it’s really more powerfull.
a real beast, good tame !
I still need to see if it’s really more powerfull.
