| New driver, help needed (Turnigy Trooper SCT)
Hello everyone! First post, I am a newb at cars (3D flyer). I bought my first truck, a Turnigy Trooper - just kidding around and making some mods. I am IN LOVE with FOFF...what do you think, can I make a budget build out of this? I know to use tools and have access to a nice production facility (Rimac Automobili, Croatia) |

Get some paddle tyres and wheels, fit them and see what happens. I don't know anything about the Turnigy trooper, so difficult to give any advice. Experimenting is fun anyway.

best advice...sell it and get something more suited to high power gear and has a better back up of parts...

Yeah, nah, more like... advice. Zedooo said 'can I make a budget build out of this?' The answer is yes. You can make a FOFF rig out of most 4WD RCs. If I were you Zedoo (I'm presuming you bought it new, if not then I'd roll with skidtoy's idea cause you won't lose quite as much $$$$) then I'd go with what you've got. I'd get a 3S lipo for it, chuck a set of mounted Proline Sandpaw 2.8 paddles, a heatsink with fan for the motor, ESC fan, and fiddle round with the gearing. You may also want a faster servo, but after getting the gearing right it should run fine. If you do go this way make sure you pick up a infrared temp gauge so you can find the highest gearing you can get without overheating the motor and if you have spare $$$$, then I'd get a new body cause those SC bodies can 'balloon' when you get going quick. Lastly a undertray to slip under your chassis would be good to keep water spray from wetting the servo, ESC and motor, plus it'll keep junk from filling your chassis. If you can't find a undertray then, go by this rule: If it wont stay out, once it's in, let it out! Pretty much just drill a small (say 2-3mm) hole in the tub of the chassis in anywhere that water or sand could hold. Then, go for it!!!! Last edited by TrilloThrillo110; 11-07-2014 at 12:36 AM.

Others, remind yourself of your first RC truck..I'm sure you didn't know much and needed help but still just wanted to drive the heck out of it ATM I'm waiting for the pinion because it worn out really quickly (bad meshing from the factory I guess) I already have the 3S lipo from my planes, the truck goes really nice with it. Can you give me some links for the undertray? As I've said, I'm a complete newb so bear with me :P | |

Hey Zedoo, Just spent about two hours getting a huge answer (videos, pictures, links) and I just lost all of it cause of Auto-Log Out. Will make a new (and better) answer soon but GTG now. Sorry |

Oh no, hate it when that happens I have a Turnigy Trooper, I locked the center diff the other day because I hate it and now I'm just waiting for the 14T pinion to get back on track...then we will see. |

Right, so now that we have that out of our way, the answer truly begins. So, Proline used to make undertrays for Traxxas Slashs, but they're now discontinued. But, JConcepts make overtrays, and not just for Traxxas either. Seeing as you Trooper is going to be different than a run of the mill Slash or Sc10 is chassis design, the overtray is probably going to need slight modification. Now, I looked on Google for photos of a Trooper chassis but couldn't find ones with enough detail and different angles to be able to suggest what tray to start out with so, you'll have to figure this out yourself. JC make trays for Traxxas Slash and AE SC10 so you'll want to start out with the tray that suits your chassis closest. My guess is that the AE Sc10 will have a closer design to your Trooper rather than the Slash's high COG design. Here's a few photos. The Team Associated SC10 The Traxxas Slash It'll obviously need trimming and stuff but as long as you order the 4WD overtray, it should be modified reasonably easily (famous last words ) To mount it I'd recommend using double sided foam tape (it's what I use to mount my undertray on my buggy). To stop the paint coming of your body when the overtray rubs after FOFF sized air, you'll want to mount single sided foan tape on all the pionts where the body may contact. It doesn't have to look pretty, just has to work. Now, in my last answer, there were some things I couldn't believe I forgot to mention, and most of it revolves around suspension 1.) Diff Oil Now, I'm glad to hear that you've locked the centre diff, but you'll also want to tighten up your other diffs. You'll need to fill the with much thicker oil due to the traction 2.8 paddles will give you, ans also to make driving FOFF easier. Changing diff oil isn't too hard but if you cna't figure it out you can Google it or look it up on RCC. I'd recommend starting out with about 500k weight oil and go from there. 2.) Shock Oil With the huge jumps and high speeds you'll be going at you current dampening set-up probably won't last that long. Thicker weight fluid will be required. Look around the FOFF forum here and ask guys what they run, no doubt they'd be happy to help. Then, take an educated punt at the weight you want to run and try it. Not working? Change it for softer or harder or much about with the pre-load. Here's a video on how to change shock fluid. (Cause everyone likes videos ) 3.) Shock Bodies This upgrade is nearly a MUST. The bodies of the shocks that come standard are thin and wimpy so an upgrade is required. Aluminium shock bodies are available for sub $25 and it'll take the punishing so much better. These upgrades are available straight from HobbyKing and are designed for Troopers so they should work well. There are the standard Electric upgrade or you can pick up the Big Bore Aluminium shocks for the Nitro Trooper which will have stronger shocks (which may actually be too strong), so you take your gamble . 4.) Springs Now, even though your new shocks with tuned oil in it will be good, the probably won't be perfect without spring adjustment. Start of by mucking round with the preload, and see how you like it. If you're unable to get adjustment far enough then stiffer or softer (which is unlikely) springs will be required. Springs are simple to change and you see how in the video on how to change the shock oil, so no instruction here 5.) Shock Towers The shock towers on your Trooper will no doubt be plastic, which bends. This upgrade is not a high priority but I'd recommend it. You say you have access to tools but what are these tools, and how specialised? Because I don't know of any upgraded shock towers for these I'm supposing you'd have to make them. This would probably require a CNC machine or a person with fabrication skills to do this. Extra shock adjustment points could be helpful too . Note: This really is NOT required, just something that will make your rig handle better Ok that's all from me, but one thing I'd like to know, what's your motor's diamteter (I need to know this for the motor fan) That's all from me, Cheers, Trillo ------------------------------ JConcepts Overtrays: https://www.jconcepts.net/shop/search?terms=tray (Make sure you order 4WD) Shocks: Aluminium: https://www.hobbyking.com/hobbyking/...r_SCT_4X4.html Aluminium Big Bore: https://www.hobbyking.com/hobbyking/...r_SCT_4X4.html ESC Fan: https://www.hobbyking.com/hobbyking/...Turbo_ESC.html Mounted 2.8 Proline Sand Paws: TowerHobbies.com | Pro-Line Sand Paw 2.8" All Terrain Tires Mounted (2) ------------------------------------------ Note; When ordering through HobbyKing, you can get some money off the item you want to purchase through a one time offer, all you have to do is stay on the page of the item you want for quite a while, so leave a tab running with your item you want to purchase on and you can come back a while later and they'll be offering a few $$$$ off your order Last edited by TrilloThrillo110; 11-14-2014 at 09:30 PM. | ||

| Re: New driver, help needed (Turnigy Trooper SCT) I spent a looong time getting the old tires down with cooking (I just wanted to put in a good foam insert, HobbyKing decided that 1 is enough ) Got that sorted, repaired the shocks and filled them with thicker oil. That went extremely well, much stiffer now. Did some adjustments, have to test that out because I'm still waiting for the damn pinion to arrive My electronics are now fully waterproof, I coated them with polyurethane lacquer. Still working on the undertray overtray thingie. We can manufacture almost anything when the machines are not at 100% Even got a idea to CNC out a chassis maybe, just need to find a nice plan. |

| Re: New driver, help needed (Turnigy Trooper SCT)
It's lookin like your off to a solid start. Locked center diff, 3s Lipo etc. You also want to lock up the rear diff and put in some serious thick silicon in the front diff or even lock that up too. (if you want to turn it into a dedicated foff rig). Paddle tires or really aggressive oversized tires should be your next investment. Besides those items, testing, tuning, tweaking the shocks and gearing will be a fun process!! My slash 4x4 has become a dedicated foff rig and I'm lovin it. Your gonna love yours! Happy thrashing!! |

Zedooo, about the 2.8 paddles I mentioned, I recommend them, but bear in mind, a lot of body will be needed to be cut. If you want to keep the body straighter, and keep the similar gearing then 2.2 Sand Paws may be the way to go. One thing I forgot to mention, beadlocks. They are a definite must for the bashing a FOFF rig'll get |

| Re: New driver, help needed (Turnigy Trooper SCT)
Thanks very much guys nice to see the thread going...really hard for a newbie to start with this I'm guessing we need a high wheel speed for FOFF? I am having a real problem getting the pinions for testing for the stock setup so that we'll have to change also. What is the "normal" setup for FOFF? How much kV on how much cells via how much teeth? Anyone have any plans for a rig that I can make i the future maybe? |

Your running 3s on your rig now, so that's a solid starting point. Does your truck have adjustable motor mounts? Can you run a bigger pinion? If 14t is stock, look at stepping it up a few teeth and then start keeping an eye on your motor temps. See how far you can push your stock system before you look at replacing it. | |

I was just asking for a ballpark figure so I know where I'm at Now it's 3S@2050 or 2080kV, 14T M1 3,125mm pinion (impossible to get in EU), 45A cooled ESC. Will upgrade to 60A, another tires, motor cooling. Off to look for the 15 or 16 tooth pinion then |

When your lookin to upgrade your esc, look for the 80+ amp range. Those will handle the higher kv motors on 3s and bigger tires. |

Seems that it would be better to start out a real budget build and leave the Trooper like it is, with this small upgrades. It's my only truck, I need to leave something for my GF to enjoy also | |

| Re: New driver, help needed (Turnigy Trooper SCT)
So guys, do you think 2.2 tires are better for my setup then 2.8? ATM the setup is cold at 2S, warm at 3S, I think I could go for a bigger pinion/wheel diameter...what do you think? |
