I have a hpi 4.6 trophy truggy and I would say this is a superior unit based on the 3 videos of yours. It clearly likes the bigger tires for the ramp jumping, otherwise it looks like a well planted little ripper.
cut my oem mounts down box works great now as i hate pull starter engine was finiky for few tanks after break in but now shes flying, going to go race it few weeks, got few 4.0 upgrades for it
I’m sorry I thought you said 30% amsoil nitro fuel. If that wasn’t a mistake do you mind putting a link up I have never heard of it or can I find it on line. Unless you are mixing it yourself
