As the title says, I'm trying to find out if the OEM Nytro muffler is also a spark arrestor?
I don't see any sort of indication that it is and I MUST have a spark arrestor on my vehicle (live in the desert - look at the grass funny and it goes poof).
If it's not, does anyone know of a slip on other than the Supertrapp or EMPI stacked plate setup? Looking for a screen insert.
MPI supercharged Nytro powered driving Polaris XP1000 drive train on a completely one off chassis. Scaled down four wheel drive Trophy Truck front suspension, scaled up Can-Am X3 rear suspension.
Honey, I shrunk the Trophy Truck!

Zero answer on the sparks but love your hobby garage and the P51 RC plane! Does it fly? I am building one now... Love the air hose reels too... Oh and the scale truck! Is a Nytro engine enough for that? Looks fun.

Lol. Yes, it’s a Dynam P51B that I fly often.
Engine will be making just north of 200 hp on pump gas and weighs in right at 2,000 lbs. It’ll rip.

No, no spark arrestor on sleds.

Definitely! The tune is way off as is the clutching and a couple sensors aren't reporting (RPM, boost pressure - AiM dash programming issues I'm sure). Check the speedo change when I step on the fun pedal:Hooray! said:Is a Nytro engine enough for that?
Cool, thanks.74Nitro said:No, no spark arrestor on sleds.
Kinda what I thought/expected. Fire's not an issue in snow covered lands unlike here in the desert.

Yeah, that looks like the route I may have to head down. I was trying to avoid disc style and stick with screen.might get away with a supertrapp for a tripple street bike.
Probably gonna end up making my own and hoping that AZDOT lets it slide.
