I am not sure what you mean by it's difficult if it is your first crawler. I just completed my first crawler but i dont think its difficult to drive with 4WS setup. Unless you are talking just rear wheel steer...thus you have to drive it like driving the fork lift..lol IMHO, with 4WS, it improves our turning radius since clod has very litle turning radius. that is what i thing. The senior crawlers might be able to help on this.. |

| If you're going to build an unlimited class crawler (14"+ WB), then you'll want rear steer. Clods have a very limited turning radius, but that can also be helped with CVD axle shafts. Plus, most comp courses are set up with gates that require tight maneuvering. If you're gonna try and build a 2.2 size crawler (approx.12" WB), then rear steer is up to you, but most rules don't allow for it. IMO, get the rear steer, you'll never look back. Make sure you use independent rear steer, and not just a servo reverser. Get a TQ3 from http://www.thecrawlerstore.com with the rear steer toggle already installed, and you'll be half-way there. -WRM |

Rear steer makes turning so much easier, because you won't have to do a 30 point turn  The initial monetary cost is higher due to the electronics needed to run an extra servo, but you won't regret it. To use 2 servos you will either need an Electronic Speed Control with a BEC (battery eliminator circuit) with a rating of 3 amps or more OR you can use a reciever pack to power the servos. There are 3 ESC's that I know of that have good BEC's: Tekin Rebel 2 (5 amp), Novak Super Rooster (3 amp), and Novak Super Duty (3 amp). A reciever pack will cost less, but it is a hassle to deal with and it adds unnecessary weight. |
