Oh, ok. As I said, cardboard ramps aren't for things like Xmaxxs, unless you re-inforce the ramp with metal or wood strips. My R/Cs are both less than 2.5 pounds each (my buggy is the heaviest of the two at ~2.2lbs), and I like to really cover the ramps, strengthen, and protect the surface with Gorilla (and other tapes) tape. I also don't use them frequently (that reminds me, I should get the ramps out soon). I haven't bought the TBR ramps either, too expensive and overkill, plus I have ramps already. Exposed screw heads are just stupid, use countersunk flush screws TBR! Seems their ramps aren't on the same level as their bumpers (I have one of their front bumpers on my 144001, very good quality and finish!).
Whaaat?! $350 for a wood ramp? That better be a revolutionary ramp design! Are you using top end treated wood, assembled by a professional craftsman! I'd recommend go to Home Depot or Lowes or somewhere, buy the wood yourself for $50, and build it your self. If you need directions, search on YT "Wood MTB ramp" or "DIY small mountain bike ramp", and you'll get some helpful videos. If you go by their ramp dimensions, remember to like double the width of the ramp, as bike ramps are a bit narrower than RC ramps (you have more control of a bike than an RC at high speed). Be sure to search for smaller, portable ramps, or you'll find videos of people building full size dirt jump or slope style wood ramps 8 feet high!
