just ran my buggy for the first time! Box set up was great! Is there a fix for the rubbing spring issue?

*Does it comes with shock oil?

*I'm on a budget and a local club racer, what will be a cheap servo to use?

Thanks.
I picked up the aluminum servo saver arm. Really the only thing i was told to buy right out of the box

right away ! quality is very good overall. many nice details

some points i noticed :
- I had to drill the arms to have a perfectly free suspension.
- the manual missed some point to thread lock : the 4mm Under the aluminium motor mounts, the steering posts ( up and down ). those are places that will surely fall apart without threadlock !
- I wished that the bevel pinion and the conical ring gear worked softer together. i didn't even put the shims ! perhaps it will get better after a few packs !
- the steering doesn't allow much droop.
Anything that is metal, pretty much assume your putting loctite on.
You might wanna make sure you have everything together correctly. This buggy has quite a lot of droop. Its more then i usually run

aparently Mugen did not update the spring diameter for the 7r, since the 7 used 15mm shock bodies and the 7r uses 16mm shock bodies, it will rub. One thing I saw yesterday on my local track, is that most guys are using Kyosho springs

Default Did I choose the wrong category?

I just bought an e-buggy (MBX7r Eco), but now looking for setup ups and videos
etc, I found that there is not much of a following from Pro-Racers or many 'Big' races. Mostly everything I found are for Nitro Buggy, even Mugens own Adam Drake does not race his Eco at all (I have not found a single video of Adam racing the eco on a big race). So now I'm kind of disappointed and might be looking at selling the Eco and get a Nitro.

What you guys think?
