I’m planning to build my own Trampa DIY, but before i will buy all the stuff (new or used) I want to check with you if everything is ok.
And also some question to make my build good en compleet.
My big inspiration for this build is: @Daniloquacquarelli . Thanks for the good ideas
Drive: Dual Direct Drive MTB Trampa (1:5 Gearing) @Nowind
BMS: FPM (FPML12S150F873)
Charger: ?
I think i have all the necessary stuff in the list.
But if you can see, i’m still looking for a good BMS and a charger to charge this beast.
I have a charger for my RC, maybe i can use this one, but i’m not sure.
The charger what i have now is a HTRC T240 DUO.
If I have something wrong in this build, please let me know. I am new to this and want to learn.
So, any advice is welcome
If you plan to go off road and ride on trails I would not go for a under board tray. Impacts are happening all the time and the ride is half the fun if you always worry about the impacts.
Think about it for a while before making your final decision.
Thanks Trampa for the tip.
My planning is not to go off road for jumps or other pro stuff.
I would usually be on the road or on a gravel path or a forest path.
Or enjoy touring through the city.
Gravel and forest is already impact prone terrain. Gravel is thrown up by the wheels, forest roads are full of sticks, rocks, potholes, puddles etc. Top mount is simply worry free.
Part choice seems all right. Something to look out for: Deck ply. How heavy are you? I am ~70kg and have the HS11 16ply. In my opinion it has more than enough flex. But that may be a matter of taste. If you have an under board enclosure more ply is definitely safer.
That being said, if you don’t do jumps or ride straight through the woods, an under board enclosure will be fine, the bottom of my deck is the only part that isn’t covered in mud.
@Benjo, i’m around 75/80kg and i have check Trampa website for the ply on the HS11, so I don’t know if this is good or to light.
I don’t want to flex, but also not to stiff.
I will do more speed then off road, so I don’t want to have a wobble by high speed, but I like the comfort of the flex.
All I can say is that if I am standing on my board with my 70kg I can make it flex a few centimeters up and down by bending my knees and extending them again (no idea how you call this. Like jumping up and down, but not really going into the air and also only very gently) that’s the right amount for me, might be different for you. Search a bit for different plys on the forum and also on to see what others have. Good luck with your build anyway.
@itsrow; do you have bad experiences with Flipsky ESC?
Normally I like to keep the brand close to each other for the best communication between the components. Please let me know your experience.
I have chosen Flipsky because I think this is the best value for money, but I can be wrong.
@Benjo; Thanks for the tip. On the form it is hard to find this kind of info, everybody is using the board different. But i also think the 16 ply would be better.
Maybe @trampa can help with this? just to be sure!.
@Fosterqc; can you tell me what you mean? My idea is to make the enclosure waterproof and the motors are also waterproof (I read this somewhere).
I’m still looking for the best BMS and charger…
I have now for my RC the HTRC T240 DUO charger, but don’t know if this works.
for the BMS i’m thinking on a Deligreen 12s or a Balance Protect Circuit PCM BMS, see below:
Also i don’t know how much amp i need for the BMS? can somebody help me with this?
