Yeah I would be keen to see the logs for this.

I wis6h think it’s a software thing. What control mode are you using?

Current mode

You both have a metr pro right? a log with full throttle both forwards and backwards may help since we can see the PPM

and also one with the motor stalled (board against a wall with full weight on the rear so it doesn’t turn into a burnout) both forwards and backwards

Do it quickly to avoid burning something if either of you don’t have temp sensors

Mine is in pieces for upgrades at the moment, i’m sure @rich will be able to document it pretty well tho. Once mine is back together I can try then

:smile: that’s how I feel with my bro deck. Need more practice to get a smoother landing done. Riding a 15ply trampa for years is a totally different world. The first rides I was just landing like a nasser sack :joy: not the most pleasant thing for your knees so…

Nice ramp you found!
May I ask what you paid Forman’s what’s there weight?
I‘m looking for a ramp for about a year already. But not having a car and not wanting to spend 500+€ for it makes it a bit hard.
At the end of the last year the hopper ramps have been on a good sale to make space for the new collection. Might be end of this year as well. Shipping within EU seem to be pretty ok. To Russia unfortunately not, that’s why I didn’t buy one in the end.

Unfortunately not just the normal Vesc-Tool Log so no PPM data

Hmmm not sure yet if I shall risk this with the Fsesc 4.12 :fire:

:joy:
Yeah also the impact sound is loud and epic. Do you have the medium or stiff Bro? I have medium and it’s much more flexy than the MBS DWII but still quite stiff compared to Trampa. It’s hard to ollie the Bro and the DWII.

The trucks are on the Bro, just need to install bindings and mount electronics

Going with a wood plate again, double sided tape on top and velcro on bottom, not long lasting but quick and easy.

With shipping it was 67€ :stuck_out_tongue_winking_eye: I think it’s about 6kg and up to 90kg rider weight.

Mabe it needs some reinforcement in the middle because it’s hollow.

But anyway I need a construction with wheels so I can tow it because I also have no car.

Good hint :+1:

So sad they do not ship to Russia :joy:
Looks indeed like it would need some reinforcement but for that money it’s not bad.
With the hopper ramp I worry a bit about there cut outs and our small wheels. Could be a bit scatchy maybe.
The ramps okp was using last year are dope, but you need two which makes it super expensive and they are anyway sold out everywhere.

I have the stiff Bro deck, but I guess I’m also a bit more heavy than you, so should come out the same in the end :sweat_smile:

Just as a additional safety :wink:

Very old school, I’m using velcro straps :wink:

Just finished the board :metal: and go for a ride before it’s too dark for the video. Second chance for the Bro.

I was just too lazy to order velcro straps. I had it on hand. :joy:

In my case with lipos > :fire:

I just measured the board and it lost 0.4kg :sunglasses:
It’s 12.6kg (27.8lb) now with the Bro deck

Hopefully I can ride on the weekend. :pray:

Compared to the DWII deck the Bro feels promising :grin:
Did some test jumping in bmx and skate park and liked it. It seems I can achieve more air thanks to the little flex. But to ollie is still as hard as with DWII.






I did record video footage and logs but need a bit time to prepare it.

I’ve uploaded a video showing my personal problem with the Bro. I think it’s just me but I can’t do tight turns with the Bro. With the Trampa or DWII deck it is no problem. This is the reason why I switched back to Holypro deck on my regular MTB.

On the Jumpinator the Bro deck feels better and I can live with less turning ability which can even be an advantage for jumpig.

I think you get more turn on trampa because it compresses in the turns when your weight acts as centrifugal force on it. And when the trampa deck is compressed, the tip angles go up. And your turns get tighter. And this doesn’t happen as much with the stiffer decks. :grin:

I’m just thinking out loud. What do you think.? :man_shrugging:

I think you are right.

Yeah that definitely sounds right.

trampa decks have very little twist in them some when you turn it puts more force into the trucks, where as wooden decks can twist easier so when you turn, the deck won’t put as much force into the trucks. same thing happens with hammers a fibreglass handle will send shocks into your hand where as a wooden handle will absorb some of the shocks as it flexes a little.

I do not agree with you…I can twist my Trampa boards to turn like race cars…I love woooden boards, but they do not behave the same way and they change a lot under different weather situations. like high humidity or dry wheather…I trust Trampa to behave the same way always…I remmeber my first composite snowboard from Burton, very technical ridding, where flex it is always the same, so the board put some limits, not the wheather…So composite works better for technical riding, against wooden boars…othewise, F1 cars will be made of wood instead of composite fabrics…I would like to say, I love both materials, to use under different situations…Get in touch with earth = wood…winning races = composite…

Well that’s a valid point but I can do tight turns with the ultra stiff DWII wood deck, too. :man_shrugging:

My personal issue with the deck is the width of the Bro. It is comfortable to ride but I can’t transfer power to the edges because of the width. On an standard MTB deck there is an overhang of the shoes which I need. E.g. on tight backside turns I grab the edge with my toes and lean as much as I can without falling. I can feel that I put all pressure and weight exactly to the edge. On the Bro my toes are angled upward and have no overhang so it is impossible to put the pressure/weight on the edge therefore I can’t do tight turns.

I’m not sure what you mean. Trampa decks twist like a pro it could be called HolyTwist. The HolyPro is still my favourite deck for riding because it’s very flexy, comfortable and I can ollie much better compared to other decks. But there are cons as well, Trampa decks are not easy to control especially offroad at higher speed, the deck bends and twists in all directions and gets unpredictable at some point.

I was happy with my Trampa until I bought the MBS. I realized that I can ride much better and precise with the MBS. Due to the stiff deck the control is direct and very predictable. E.g. on a certain single trail I crash 8 times out of 10 with the Trampa and only 2 of 10 with MBS. That’s why I bought MatrixII trucks for the Trampa because I first thought that’s the reason for better steering. Well after installing them I instantly knew the deck is the problem not the trucks. That’s why I bought the Bro… and couldn’t steer.

That are some serious first world problems :laughing:
