so why do they refer to the 5309 as the new model that is larger then the previous revo ? and the 5309 is the 2009 model?
further supports that 5309 is the newest model of the revo--

this link shows the 5308 --- in 2008 release date?
Yeah, the 5309 was released before the 5308 originally. You'd think they would go down to 5307.
Revo Family
The Revo family consists of several models originally based around the Revo.
[edit] Revo
The Revo was introduced in 2004 as a complete redesign of a monster truck chassis with a more advanced and reliable design than the T-Maxx. The Revo has become popular in racing, and is also well suited to "bashing" environments such as a backyard or a construction site. Notable characteristics include the inboard pushrod suspension system with new "GTR" shocks and springs, a complex "monocoque"-type aluminum chassis which lowers the vehicle's center of gravity, a stronger transmission that features electronically controlled reverse, sealed limited slip differentials, rubber sealed pivot balls, drive shafts and ball bearings, 3.8 inch wheels and all-terrain style "Talon" tires, and an updated version of Traxxas'
TRX 2.5 engine, the TRX 2.5R. It has a claimed top speed of 40+MPH.[8]
A new Revo version was launched alongside the T-Maxx 3.3 in 2006, with Traxxas' new, more powerful
TRX 3.3 engine. Because of the demands of Revo owners, the chassis was lengthened 30 mm for more stability, and the motor mount area was braced to prevent it from bending. Other minor changes included a longer version of the body with a new paint scheme to accompany the wheelbase stretch, and new wheels. New add-on upgrades were released, including a center differential, that helps transfer power between the front and rear differentials to increase handling, and a rear-braking module that must be used with the center-differential. It has claimed top speed of 45+MPH.[9]
In April 2008 Traxxas released the limited edition Revo Platinum. It came stock with most of Traxxas upgrades and tuning parts normally available as accessories for the standard Revo 3.3. It was intended as a factory racing version of the standard Revo 3.3.
Later in 2008 Traxxas released a revised version of the Revo 3.3. It incorporated some of the features seen on the Revo platinum, including a polished "Resonator" dual chamber exhaust pipe, dual stage air filter, larger 150cc fuel tank, teflon coated aluminum "GTR" shocks with titanium nitride shafts, 17 mm splined wheel hubs. As is typical of a new Traxxas model, the revised Revo 3.3 received a new paint scheme.[10] #5308
In July 2009 Traxxas introduced a further revised Revo 3.3. Changes included a new body with new paint and graphics, new dual waterproof digital high torque steering servos, Traxxas' new 2.4 gHz radio system, an improved "Optidrive" two speed reversing transmission, and new progressive 2 suspension rocker arms. Also, new deeper offset 3.8 inch "Geode" wheels increase overall width by 1 inch and new 6.3 inch "Monster Maxx" tires (lifted from the current T-Maxx) increase ground clearance by .25 inches to 4.25 inches and overall height by .9 inches to 11.02 inches.[11] #5309
