View Full Version : A few quesions about the MP
High there, i'm lookin at a few models right now and i usually dont clutter up the boards with my useless garbage but in this case, being a shortage of MP information and all i feel as if i dont have any option.
I am just wondering how good the suspension on the MP is, i've heard rumor's that its rubbish but it can be made brilliant with small modification, how is this done and is it really a rubbish suspension stock?. Also those tires are SURE BIG and i was wondering if a Hitec 645 will do for the steering and a Standard Ball raced Hitec Servo for the throttle. Will the 645 be enough for the steering and will the standard ballraced hitec servo be enough for throttle duty?. Thanks in Advance

Here's good thread on the MP
http://www.radiocontrolzone.com/forums/showthread.php?s=&threadid=57585
To make mine better I enlarged the holes in the piston, put a heavery oil (100wt), replaced the stock springs with a hard set from Ofna and drilled holes in the rims.

my friend put pro-line t-maxx tires on his MP, and he replaced some of his shocks(which really don't need replacing) from an old TTR buggy. I used my friend's MP with everything stock and it was great. He had a USA-1, but sold it for the MP. The MP is just a modified buggy, so it handles great, but it doesn't do as well on teh jumps as a T-Maxx. There's some good info about the MP in the November issue of RC Car Action - it's the RTR T-Maxx vs. the RTR MP. MP handles better, and it goes faster!

Even stock, the MP is a kick butt Monster Truck. It is huge and a blast to drive. As with most RCs, hop-ups and mods are part of improving performance and durability. The 645MG is basically equivalent to the steering servo that comes in the Ready to Run MP. It will work OK, but with those huge tires, the more torque the better. I would recommend running a 6v rechargeable onboard battery to get to most out of the servos. The stock servo for throttle/brake will be OK, but it isn't very strong for applying the brake. The truck weighs around 11lbs and I think eventually, that will take it's toll on a stock servo. You can always upgrade the throttle/brake servo in the future. Again, this truck is a blast. You won't be disappointed. Good Luck
after reading up on some stuff i get more and more interested but i want something that jumps well and is fairly user friendly. I know about R/C and Nitro a fair bit but i've been on and off the hobby for ages now so i am still fairly new.

The T-Maxx would be a great truck to get. Even with the .15, the thing has good bottom end, and great top end. The thing jumps like a plane flies, and takes the landings like it is landing on marshmellows. It is also a great climber.
The only thing really wrong with it stock is, it flips easy, because of the high ground clearence.
i know a T-Maxx would be a obvious choice but i don't like it, not THAT strong, under-powered, epensive and needs cash putting into it which i aint got.

Suprisingly, it is strong. It really isn't underpowered, that is just what people who haven't driven it, say. If you want a truck with .21, that really doesn't jump as well, go with the Thunder Quake.
i have no idea how much i want a TQ but they cost $750

i think the mp is dope! you should get it, it looks really good. From what i have hear it performs nicely stock (all you need to do is drill 1/16 holes in the shock piston). if you get a tmaxx youll spend way too much money on hop ups and eye candy, when in contrast the mp will need almost no hopups to perform nicely (not trying to say the tmaxx performs poorly). but alum. gear casing is a good hop up, almost a neccesity. SaBr makes all the stuff you will need for the mp, at low prices. I have looked into the tmaxx vs. mp issue myself, and I have concluded the mp is a better choice (for me at least).

1.dragg, face it, the Tmaxx is way underowered for its size, thats its main drawback you cant fight it no matter what, just like i cant fight that my MPs stock suspension bites
2. dont waste your money on a TQ, they arent even worth it, an MP with no shocks could outclass one of those things....the TQ is just an NQ with some decent tires and flash A-arms to make the newbs ooohh and ahhh :)
3. if your gonna use the 645....do not use a 4.8v pack, its makes steering unbearable. im usinga 4.8v and a 645 right now and it doesnt cut it for me...or anyone else who likes turn in the corners whil going fast

Andrew, it really is not underpowered with the 2 speed. When tuned correctly, the thing has good acceleration, and great top end.
Andrew the RC man

drag-its unerpowered compared everyother big monster truck of ts size, ya the 2-speed helps, but not much. good acceleration and speed huh??? personally i think its rather slow acceleration and speed. in thespeed and acceleration, it has nothing on anyother MT...excluding those kyosho QRC things...i dont even know what you classify those ugly things as...
draggerman11
12-15-2001, 06:38 PM
Andrew, those "things" are 2 wheel drive, and smaller, so the acceleration in theory should be higher.
In my oppinion, the acceleration, and top speed is great. It may not be on par with the other .21 monsters, but with few modifications, it is right up there(Those being TRX being bored out, AE Tuned Pipe, and The Hobby Shop Big Tube Header).

*BUUZZZZZ* wrong! the little QRC things are 4wd
honestly how many people know how to port a TRX, i hear it is very complicated. also even then i dont think it could do as well as a .21 MT, the truck would be bearable....but still not up to par with the others
draggerman11
12-15-2001, 07:09 PM
Yep, they are 4wd. Just wondering, have you seen one ran? They only top out at 25 mph, so the stock engine isn't any powerhouse.... Also, it is still smaller, and lighter, so it should have better acceleration.
As for the porting, there is a guy that does everything for 35 bucks.

whats porting? (as you can tell im not a big nitro guy, but i am learning)

The piston sleeve in an engine has holes or ports for intake (incoming fuel mixture) and exhaust gases. I have also seen modifications of the exhaust manifold port. These holes are of a certain shape, size and position when the engine is stock. Porting an engine means carefully and precisely changing the size and/or shape of the ports to increase engine power and performance.

inferno- do i dare ask at the risk of being wrong, why would you want to port your exhaust?? wouldnt that decrease your power.
draggerman11
12-17-2001, 12:11 AM
I believe the logic behind it is, the bigger the opening, the more exhaust gases that can leave, which should increase power.
Andrew the RC man
12-17-2001, 03:27 PM
ya, but the way im thinking is, if it is a smaller whole, then you engine will push more to get the gases out...hmmm maybes it one of those rpm/torque ratios

why dont companys just port thier engines right off the bat? It seems like an easy way for them to make an engine perform better- effectively.

It think it has to do with shaping the exhaust port for maximum performance and more efficient flow. Identical stock engines can be very different from one another. The way parts are manufactured, assembled, or seal will differ slightly. For hard core racers looking for every edge, I guess those little mods can add up to better performance and an advantage. For the average Joe I think it's a bit complicated.
