What are you putting it in? I'm assuming a maxx? Since this is in general nitro, it's hard to say...
If it is a maxx and if you got this engine:
Wasp With Slide
It will also depend on what engine is currently on your maxx. If you have to 2.5, then you already have the slide carb setup. If not, then your going to have to do some figuring to get it to work. Also, if you have the 2.5, your going to need this to put the wasp into your truck:
Clutch Adapter
If you have the older maxx and the engine had a rotory carb vs a slide, then your going to need to do some figuring again.
I have more info if you need it. I just put the same engine into my 2.5 maxx, but I did a lot of remanufacturing to get the truck the way I wanted it. The 2.5 slide carb setup is crap. For me, it made the carb bind up no matter how I bent the throttle wire, so I moved the servo by the engine, put an OFNA buggy tank up front, mounted the receiver over the steering servo and put the battery pack ziptied to the chassis where the battery pack originally went.
I can post pics if you want. It's not pretty, but I got 2 hours of playtime out of it today and had a shiteload of fun. The only thing that happened was I lost a rear turnbuckle screw near the end of my outing.
