Whats up Nitro Addicts......Im sure your Classic Pro.15 or 2.5 model 4910 T Maxx can use a new powerplant and attitude.....Mine did...First I tried taking a dremel and making the Pro.15 engine a turbo engine to increase its power and revs.....That went well but the truck became like a streetracer now with a powerband too high of an rpm for any type of control on dirt so I stuck it in my on-road car and put an OS .18 CV-R engine in it...The OS engine had some power but not as much as the 3.3...Im not a 3.3 engine fan and neither was my 4908 extended T-Maxx...The 4908 truck even stock was a little too heavy for the power of the 3.3 engine and it ran hot and was hard to tune...the 3.3 in the 4908 T-Maxx made way for Sirio .27....The 3.3 soon became transplanted into the 4910 model with great success and a little cash I might add...The lighter truck makes the 3.3 engines power feel endless plus its now running alot cooler and is also alot easier to keep in tune...The only problem I have with it is keeping all 4 wheels on the ground at top rev because it likes to backflip over alot....
Some say putting a 3.3 into a classic body style T-Maxx is pretty hard....I found it rather easy and the black case transmission has been holding up very well and gives the truck a slightly overall better controlling ride compared to my 4909 model with opti-drive before converting that to twin 3.3's....Thats for another thread...Alot think the 3.3 trans is better bigger and the way to go....It just adds to the project costs and adds to the loss in useage time...
I used the 3.3 engine with exhaust manifold,black case trans,22t bell and 72t spur gears for the primary drive....The rear/front centershafts were beefed up using the 4908 centershafts but I had to use the 4910 ends at the trans output shaft connects so theyd fit onto the output shaft ends seeings the classic maxx trans output shafts are smaller than the grey case trans plus it still gives me the ability to still use the fiberglass disc brake with the thicker shafts too....I had to add an extra 6 pegs to the slipper clutch gear also for a total of 12 pegs to control the slip...For added insurance I went with a RRP hardened spur/bell set........
To keep the slider end of the carb from hitting the spurgear shaft I flipped the carb and moved the fuel inlet into the other inlet option hole.....For the throttle linkage I converted an extra 4909 model type into a Revo style throttle mechanism and it works better than expected..
From the start of the project to the end of it took approximately 2 1/2 hours to do the whole retro-fit..The first time I fit it for test I used a tiger drive setup to test out how it was gonna handle and run......The narrow classic Maxx profile wasnt cutting it for the handling so I widened it with a set of 4908 a-arms/knuckles and driveshafts...after that my mini maxx was a mighty maxx...After getting impressive results from my overhaul I stuck in the ez-starter unit and now its been back in the line-up of bashers...:thumbs:
