There are many choices on the market for people who want to get into truggy racing. Some buyers prefer to buy a kit and build their truggy themselves. Many new comers choose the easy route to get into racing and they buy a Ready-to-Run vehicle. Losi has understood that many of those newcomers will quickly turn into racers and this is why Losi offers them this extremely valuable package. The Losi 8IGHT-T 2.0 RTR comes with high quality transmitter, telemetry and a starter box. Yes you read it well, a starter box is included. The Losi 8IGHT-T 2.0 RTR is certainly the most race oriented ready to run truggy on the market.
WOW is the first word that came to my mind when I opened the box. Losi didn’t skimp on quality for the transmitter. A Spektrum DX3S 3-channel radio is included with the truck. This nice looking radio uses 2.4GHz DSM technology for precise control but also for telemetry. Right on the transmitter’s large LCD display, you can quickly know real-time information about your vehicle such as engine temperature, speed, RPM and voltage. The binding process between the transmitter and the receiver has been done at the factory. The DX3S has some nice features like 10-model memory, a 128×64 hires LCD screen and all the trims and miscellaneous features usually found on 400$+ transmitters. The transmitter only uses four AAs batteries, this will make you save money on the long run. That’s a really nice transmitter. A 1400mAh NiMH receiver pack is also included in the box. I had to fine-tuned the radio’s trims and adjustments to center the steering and adjust the break end-point.
Losi has included extra high-torque digital servos for the steering and for the brake/throttle. The 80812 servos have metal gears and they produce 140 oz-in of torque with a transit time of .18 sec @ 6.0v. This is a little short in term of speed and torque for the steering. This is not a bad idea to start running the truggy with the stock servos and once you are familiarized with the truck, replace the steering servo with a faster and stronger servo.
Ready-to-Run vehicles must be easy to use because they are mainly designed for newcomers or for people who don’t want to waste a lot of time before running their vehicles. That’s exactly what the Losi 454 nitro engine is. This .28 ci engine is certainly one if the easiest engine to break in on the market, great for newcomers. The engine is topped by a huge and effective 9-fin cooling head and has a throttle return spring already installed. What is a throttle return spring? It is a little spring installed on the carburetor to force the carb to fully close in case of a death receiver pack or throttle linkage failure. This prevents runaway and will save your engine and vehicle. All engines should have one. A well designed air filter keeps dirt and debris outside the engine. I suggest you to oil the outer air filter before starting the engine. The tuned pipe does well, it is an all-around tuned pipe and produces good bottom and top speed.
The engine break in was a charm. I recommend loosening the glow plug 1.5 turn before trying to start the engine. This reduces compression and it helps to the initial start. Heating the engine with a heat gun will also greatly help the initial starts. In my case, this is exactly what I’ve done. I pre-heated the engine and loosen the glow plug. I have disconnected the fuel line from the tuned pipe and gently blow air in the line until fuel reached the carburetor and then I’ve reconnected the fuel line to the tuned pipe. It is important to stop when the fuel reaches the carburetor inlet fitting and to not force fuel into the carb. You can easily flood your engine. Once the engine is started, don’t forget to tight the glow plug.
The engine fired up almost immediately and I’ve used a little throttle to keep it running. The base settings were a little too rich for my climate so I had to lean the carb a little bit, maybe ¼ of a turn. With a leaned setting, the engine kept running rich and only required few throttle blips once and a while to clear excess fuel. During the break in process, the engine temp stayed between 195F and 205F. I’ve let the truggy ran on the starter box for a full tank. Before the first tank got empty, I’ve stopped the engine by blocking the exhaust pipe. I have put the piston all the way down in the cylinder and I’ve let the engine cool down for 15 minutes. For the second tank, I’ve heated the engine with my heat gun and I’ve drove the truck on the ground with very light throttle inputs. I’ve repeated these steps for the next 5 tanks by lightly leaning the engine out and by giving a little more throttle. After 6-7 tanks, the engine was ready to run harder.
Now let’s talk about the starter box. First, the included starter box is perfect, all the pegs are already adjusted for the truggy. All I had to do was to put the truggy on the starter box and push down to start the engine. The starter box uses a powerful 775-sized motor which has more than enough power to spin any engines.
Second, If you don’t own 7.2v NiMh batteries, I recommend that you buy LiPo starter box battery to use with the starter box. Losi recommends 2 NiMh 7.2 packs but it can be cheaper to buy a 4S LiPo battery and LiPo charger. The NiMh batteries are nice but they will never last as long as the LiPo pack and they will take twice the time to charge since you have two batteries to charge. If you go LiPo, replace to Tamiya style connector with something a little more heavy duty that will handle to the extra voltage.
Another important note about nitro engines and starter boxes. Starter boxes use at least 14v to operate and many of them use “el cheapo” wires and connectors. Don’t try to start your engine like an idiot. If your engine has not started after 3-4 seconds, stop, let your starter box relax for 5-6 seconds and then retry. The same is also true if your engine is flooded. Never try to start a flooded engine. In some cases, there is so much fuel inside the engine that the piston can’t even move up or down. This may result in melted wires or connectors causing short circuit to your NiMh or LiPo batteries, broken belt and rubber wheel wear.
This is easy to recognize the Losi 8IGHT-T 2.0 RTR with its red anodized 4mm thick extended chassis. All components are mounted very close to the center line for optimal weight distribution and handling. The shock towers also got a redish treatment just like the wheel nuts and the wheel hexes. I’m not a big fan of red anodized aluminum parts but in this case, it adds a little “cool” factor to the truck. The shock towers are thick and have many optional shock mounting positions to fine tune the suspension.
The radio tray is compact and made of composite plastic. Two different battery covers are included depending if you use hump pack style or smaller receiver batteries. The receiver compartment is also very compact which may be a problem if you need more place for your receiver.
Good points for the tires, without being high performance race tires, they are quite good enough for racing on a multitude surfaces. The compound is a little hard but we should keep in mind that they are made for the average Joe’s. Anyway, the tires have good forward and side tractions and that what’s important. On my test 8IGHT-T 2.0 RTR truck, they were perfectly glues to the wheels.
The red, white and black “forwarded cab” body looks really nice and has excellent airflow to cool down the engine. It comes pre-painted and extra stickers are included in the box. It is made of thick lexan and should resist to many rollovers and crashes. Unfortunately, there is no venting hole in the windshield, I suggest you to make one. Two body clips held the rear wing in place, I prefer screws but the body clips make wing removal much simpler.
Now let’s talk about the drive train. The truck uses a typical three diff design and all three diffs are filled with silicone fluid compared to grease usually found with some others brands. According to the user manual, the front diff uses 7k, the center 10k and the rear diff is filled with 3k fluid. This is a good basic setup to start with. The diff cases use metal inserts to hold the spider gears for extra strength and durability. Nice rubber dust covers protect the front and rear drive shafts’ joints. All the drive train rides on smooth rubber sealed bearings. Today’s all drive train are smooth but the 8IGHT-T 2.0 RTR’s drive train was particularly smooth.
Under the 13T clutch bell, four aluminum clutch shoes are found. This allows super quick and strong clutch engagement. A 50T spur gear is attached to the center diff and is protected from debris and dirt by a large plastic cover. Two thick and massive disk brake are in place to quickly stop the truggy.
The suspension is superb and very plush. All four shocks use threaded aluminum shock bodies with plastic cap and yes, they are big bore shocks. They come prefilled with Losi 35wt shock oil. All the suspension components are beefy and made for abuse. The turnbuckles are massive and they will resist the abuse of racing or bashing. Absolutely no problem here. Front and rear sway bars are installed to stabilize the truck when cornering. The bar’s thickness is engraved on the bars for quick identification.
The suspension arms have been lengthened but they still big and thick enough to handle big impacts and crashes. They make the 8IGHT-T 2.0 RTR wider and this greatly increases stability.
- GREAT transmitter
- The most “race-ready” RTR truggy on the market
- Telemetry is cool
- Start box included
- No glow starter included
- Needs stronger and faster servos
The Losi 8IGHT-T 2.0 RTR is one of the last Ready-To-Run truggy available on the market and by chance, this is one of the best, if not the best RTR truggy. It comes with a high level radio and included a starter box. It is a little expensive but when considering what comes included with the truck, it is a good deal. I wish Losi includes a glow starter, this would have been nice considering the price tag. The Losi 8IGHT-T 2.0 RTR is an excellent choice for anyone who would like to get into truggy racing or just for bashing.
The servos are the only negative point. They are good to start with and to get familiar with the truck. The truck’s handling could be greatly increased with faster and stronger servos, especially for the steering.
