Features & Specifications
Schumacher makes two versions of the Havoc the RTR and the ARR. The version I am reviewing is the RTR model that includes the radio and electronics needed to run, plus is pre-built. Whether you choose the RTR or ARR version your can choose from the same three body colors, yellow, blue and black and my Havoc was a yellow version. The body of the Havoc is quite detailed and has nice graphics pre-applied. A sheet of stickers you cut out and apply to the body comes with the truck for those wanting to customize.
The radio and electronics used in the RTR Schumacher Havoc is by Airtronics and uses a Blazer Sport radio which offers throttle trim adjustment, steering trim adjustment and steering dual rate. Three LED lights on the side of the radio show the amount of charge the radio batteries hold. While you can power the radio with eight AA batteries there is a built-in charge port for those wanting to use rechargeable dry battery packs. Reverse switches for steering and throttle are built-in and the trigger is adjustable. The servo and radio box on the Havoc are sealed to prevent water from getting inside and causing damage to the electronics.
The engine Schumacher uses for the Havoc is a E-Start ABC Pro Engine with a 4.6cc displacement. Calling the engine powerful is an understatement and at full throttle you can push the Schumacher Havoc to 50 MPH. Unlike the side exhaust pipes that the cars from Kyosho I have tested use, Schumacher uses a twin exit exhaust pipe that directs exhaust flow out of the rear of the truck. When a truck can hit speeds of 50 MPH brakes are important and Schumacher used a disc brake unit with twin steel pads.
Stunts with the Schumacher Havoc will put a lot of stress on the chassis and to prevent damage Schumacher used a 4mm alloy with a purple color that is very strong. Other RC cars that from Kyosho I have tested used a two speed transmission. Schumacher kept things simple with the Havoc with a single speed transmission and the truck utilized 2WD rather than 4WD. Two wheel drive is more durable and makes it easier to spin the truck around for stunts than a 4WD model.
Schumacher went all out on the suspension for the Havoc with tough shocks that have 70mm of travel. This truck can take huge jumps and so long as you land right keep right on running without problems. The large diameter chrome wheels have pre-glued tires for improved traction and durability as well. Under the durable body you will also find a large chrome roll bar that doubles as a carry handle for the truck. Overall truck dimensions are 450mm long x 300mm wide.
Tuning & Driving
After unpacking the Schumacher Havoc from the package it ships in all you need to add to the RTR version to get running is nitro fuel and batteries. Unlike the Kyosho vehicles I tested previously Schumacher doesn’t use pull start. Starting the large 4.6cc E-Start motor requires a cordless torque drill. The long drill bit needed to start the engine is included with the Havoc. Once fueled up you plug the twin exhaust exits and turn the motor over with the drill for a few seconds to prime the engine and get fuel to the carburetor. Then a simple and quick blip of the drill fires the motor up without fuss.
Tuning the Schumacher engine is a bit more involved than tuning the Kyosho engines because the Schumacher has three adjustment settings rather than the two that the Kyosho engine uses. That’s not saying tuning is hard, I had the nitro motor tuned for optimum performance in about 15 minutes. Once the engine was tuned it was ready for some serious fun. If I had to describe the Schumacher Havoc in two words they would be fast and tough. This truck is a rocket! The speeds it can hit on straights is very impressive.
The large tires can gobble up most road imperfections without upsetting the truck. Acceleration is very impressive and the only bad part of having all this power on tap is the truck can be hard launch without spinning if you aren’t careful. All that power also means that it can be hard to line up jumps if you use full power, though with so much power you don’t rally need full throttle for serious air. Schumacher designed the Havoc for stunts and the truck excels at that task. I jumped this truck more times than I can count and subsequently crashed it lots of times as well. Never once did the truck break.
I jumped tree roots wide open sending the truck 5 feet into the air and subsequently rolled the truck 57 times. Well maybe not 57 times, but the crash was much more impressive than the jump. I expected to see pieces fly off the Havoc and be done running for the day (maybe forever). What I found when I got to the Havoc was not only was the truck absolutely fine, the dang thing was still running. I kicked it back onto its wheels with my foot and off we went for some more fun with the only sign that I had flipped the thing over was that the impact was hard enough to send one of the body retention pins flying and a few minor scratches on the body shell.
I continued to pound the Schumacher Havoc for weeks, and still do on almost a daily basis. While the stickers are scratched and the body is not as shiny as it once was the thing just doesn’t stop. I jump it and consequently roll the truck each time I drive it, often several times per session. I once hit a tree at nearly wide open throttle and cause no more damage than another missing body retention pin. I rolled the car at full speed when a large bump threw the Havoc into the air and the truck still runs like new. The Schumacher Havoc is the epitome of tough and fun when you think about RC vehicles. The only problem I had with the Schumacher Havoc was that after the first high speed session (resulting in the big roll over crash) the screws that secure the roll bar loosened up and required retightening. A bit of Lock-Tight will prevent this from happening again.
If you care nothing for racing RC vehicles and simply want a nitro powered RC truck that is durable, easy to drive and seriously fast you need look no further than the Schumacher Havoc. This thing is neigh indestructible, a snap to start and just way fast. First time nitro RC car drivers will find that the Schumacher Havoc is a great place to start thanks to the ease of use and overall toughness. MSRP for the RTR version I reviewed here is $419.99 and I can’t think of more fun to be had for that much money.
The Schumacher Havoc is a superb nitro powered RC truck. Whether you are looking for a first or a fifth nitro vehicle the Schumacher Havoc is exceptionally well built, tough, fast and simply a blast to drive.
