I have my 3.3 installed and running, I want to run some bigger wheels i have on order. will i need to redo or install anything to run wheels 1 inch bigger? I am geared 64/24 right now. will that work ok with bigger wheels?

One inch bigger than what? It'd be better if you just said what wheels you were running (i.e. Big Joe's, Bow Tie 40's).

If you still have stock driveline parts, say goodbye. Putting more power to the ground is one thing, but adding a bunch more rotating mass is going to put some serious strain on parts. Be careful.
OK, so you have factory rims and tires on there now. How about telling us what you are wanting to put on there and again, be more descriptive rather than 7" tires. Who makes them, what are they, etc.
.21RC has a good point and he probably is right, but a narrow, 7" tire really won't harm anything, but no one knows what 7" tire you are wanting to run. See what I mean?
Think Jerry Macguire, "help me help you!"

I'd have to disagree with that statement MW....you are increasing the Centripital force exerted on the hub/driveline (yeah I'm gonna hear some mr. wizard wiseass comments for using a 10 dollah werd, but screw you MW...LOL) and this is what RC was talking about....ANY imballance in the tire will be magnified that much more and tear your stuff up quick......why do want bigger tires? is it an asthetic reason? if so just keep em for the shelf showing, because they will ultimately ruin your rig.....tires should be selected for the type of driving you are doing and not for the look.....

You may be right, Plaid (and it's centrifugal force, for those of you keeping score at home!)
My hypothesis, which may be proven untrue, is that a wide tire with a short sidewall will exert the same centrifugal force as a narrow tire with a tall sidewall. I may be absolutely wrong (as I am in no way a physics guru) but relationally, it makes sense.
I believe the underlying advice to all of this, however, is that should you upgrade to bigger, meatier tires it is worth considering an upgrade to your drivetrain to compensate for the added mass. That being said, if the Maxx you have is the 3.3 version, I believe those come stock with the Revo drivetrain components, which are actually quite tough in their own right.
Of course, I could be totally wrong, and in that case, it's Plaid's fault!

well I can say this...centripital is the external force required to rotate the mass.....centrifugal is the force that is thrown away from teh center of the object....that being the case I'd say it's the force exerted on the object creating the movement....if you want I can calc the moment of inertia created by each tread on your wheel...
.......alot of boring crap...but anywho...your logic is sound with the exception of the weight issue affecting the mass exponentially not linear as is gets further from the center of the wheel...meaning yes a wide and narrow set of wheels may have a static weight that is identical but the narrower/taller set will create more centrifugal force as it rotates...the centrifugal force is not so much the factor as the centripical force is....as your need to increase the centripical force (to generate your acceleration) goes up so does the wear and tear on your driveline...gearing can help recuce this wear on the driveline but then you are just over working (revving) your mill to compensate...man I feel like I'm useful to someone just having spouted all that.....I need a job dammit, my brain is just getting cramps and needs some excersise....LOL...
but yes MW is right the 3.3 drivetrain is A LOT stronger than the older 2.5 setup I was thinking about when I responded to this....

Man, that hurt. Just follow Plaid's suggestions and advice, my man! I gotta get a beer and slow my brain down!

dang.
LoL well they are some Hotbodies wheels i got from towerhobby and yes I have upgraded my rig so it IS 2.5 drivetrain. But check the wheels out:

They are for looks and a little bit of clearance. I got a trail out here i like to run and it being a lil bit rocky i wanted a lil bit of lift and this is easy.
