How do you add a second motor to the T Maxx? It already has the Picco .21 but I want more power out of it, would it be smarter to just add a bigger motor or buy a whole new truck to start a new project with?

dont do two motors...get a picco .26 max or a Rb 523 would be even faster.

Yeah, go with a Picco or the RB.....However, adding a second motor to a Maxx is pretty straightforward. Since the chassis is flat, there's plenty of room for the second mill if you relocate the fuel tank and ditch the EZStart. Carb linkage is easy enough, and radius exhaust headers make the exhaust a snap. There's several threads on multiple engine Maxx's on this forum.

l have to agree with the above LOLs, the two motor thing has been done a thousand times, what people just dont understand is the main gains are torque, but when you incorperate your power to weight ratio, the two motor set up looses every time, the picco owns it, two motors running side by side gives you two pistons going up and down together, not like a twin cylinder engine where one piston fires and then the other fires while the first is at bottom of its stroke, thats a power twin cylinder motor, two of these nitro things next to eachother is a torque power house, nothing more, your truck will never match a true twin cylinder or a single cylinder picco .26 or .28........dont waste u r time basicly.....

i am personally still waiting and anticipating a v-twin for our trucks. but i have seen on here about a year and a half ago where a guy put 3 traxxas 2.5 motors on a t-maxx. the only thing i could think of is how hard it was to keep a good tune on all three. also you will have one that will have a better stronger tune then the other (s) and will be your main drive while the others will just idle more.

Are these motors worth buying or should I just buy a regular one? Also, I didn't even think about it that the two motors wouldn't be in sync with eachother..

whoops, forgot to add the link.. I was busy, i won 4 monster GT shocks on ebay for $18.00 shipped..

forgot again lol.. I must be really tired..

rcboyz has awesome shipping and customer service. you gott realize if you take two 2.5 traxxas motors they are both .15's if you take one os .30 you have the same displacement. ok now you got one motor on the spurr gear and one motor to tune you will have more power. the reason people put 2 or 3 motors on a truck is the presige of saying they do. still waiting for v-2 power

So do turbo motors make much of a difference over the non turbo ones? I will go with only 1 motor unless I buy a savage x or the Monster GT then I am sure I will have to mod that a bit to get it to move like the Maxx does with the picco .21 in it..

turbos, boost bottles, and superchargers dont work on these kinds of 2 stroke motors.

actually when he is referring to Turbo motors he means engines that use a turbo button head and a turbo plug.........some of the guys at he local track swear by them....I will reserve judgement cause I have never tried one yet...

Yea one day someone with there own lathe will make there own crank, mill and mod two engine blocks to fit together and have two pistons on one crank, a true twin piston motor, that day will be the start of twin cylinder power for nitro engines.A backyard [ so to speak ] job of this type would most likely see a twin straight line config design, reason being one piston being TDC and one being BDC is easier geometry to work out than a V config to get an even power output from both cylinders , alot of people would have heard a whiny motor that lacks compression on one or two cylinders, not getting the piston position correct in a V config will have that same whiny effect, uneven power through its power/torque curve. Its especially important to get this right, and is part of the reason we have not yet seen V nitro engines, expence of reaserch and design, anyways a back yard magyver, one day some where will do it some day, l have toyed with the idea, but lack a decent lathe and mill [ ppft like most ] hahaha, has stopped me...anyways the digger that does finnally do it will be a living ledgend in the eyes of some ! From there they will design a new manifold for a bigger carb to feed two inlets [ two cylinders ] and the same for exhaust.
Putting two nitro engines together now is less power than a picco .26 or .28.
Imagine a true twin stright or V config picco .26 , eye watering stuff.

That RB523 kit looks good too, never used them before but they look alright.

that would be awesome if someone would mill their own crankshaft and crankcase and taking the stock rods and engine blocks and carbs off of an os .21 or something and bam v-twin power.
