Hi,
Im going to get a FLM bb conversion for my tmaxx and I can't decide what engine to get?
I dont want to go over $200. I was thinking about a mach 427 or a axial .28?
Any info would help.

What will i need to do to have a big block?

i dont know much about the mach but i have run my buddys savage which has an axial.28 in it,it screams,it has great power bottom to top end,and it holds a tune pretty well

megamaxx

another engine that you might want to take a look at is the xtm 24.7,this engine is inexpensive,is often overlooked as an option,i have one in my.21 conv. t-maxx,its a good solid engine,pulls wheelies out of the hole,great top end,and its almost as hassle free as my o.s. it holds a great tune

I run an Orion Wasp .28 in mine.Its cheap has lots of power and easy to tune.But if u r gonna run a big block u r gonna need to upgrade your tranny and your diffs.Otherwise you'll be replacing gears every run.I have robinson racing gears with forward only in my tranny and FLM hybrid bulks with Hot Bodies Lightning diffs and i dont have to worry about stripping anything.If u have a 3.3 tranny u might get away with just a forward only conversion for a little while but your stock diffs wont handle it.I would get the FLM diff set with aluminum cups if u r on a budget

DelimaPhobia

So can i get by with a 3.3 tranny or should i just go with steel gears?

I put a Sirio .23 in my TMaxx 2 years ago. The only think I've had to change so far was Robinson steel gear in the rear diff. Every once in a while the axle shafts wold break but that was every few months. You shouldn't need to upgrade the tranny or gears in the tranny. You will have to upgrade to a big block chassis. Dynamite makes a good conversion kit for almost $300 with a very nice Mach .26 That will probably be the cheapest route to take if you don't already have the chassis. here's the link:

I've stripped my tranny gears with a .21 picco drop in motor.And that was only after 2 runs after breaking the motor in.I say run what u got now and upgrade it as it breaks.U will definately find the weak spots with a BB.So dont be disappointed when your Maxx breaks and u have down time with it.The stock componets r not made the handle the torque of a BB

But should I go with a axial .28, mach 427, or a xtm 24.7?

Josh

I would say Mach .457 unless you look into the Axial .28RR. I have an STS .30 which I paid $140 for and should spank both of them.

If u r looking for something really cheap i heard some good things about these Go Racing Engines over on the UE forum.Might be something to check outhttp://www.rccompound.com/Engines-.26+/c23_28/p2433/Go-Racing-.28-Sport-Engine-w/Pullstart/product_info.html

DelimaPhobia

What about the axial .28rr?
any good?

Josh

I haven't seen one but it's supposed to be a much better version of the original .28.

firebird02,
What drive shafts are you running?
I was planning on getting flm hybrid bulks and some mugen mbx5 diffs in it.
But can you use those with the stock drive shafts?

Josh

Check out the LRP engines, they are super affordable and really powerful.

firebird02

I could be wrong but i dont think the Mugen diffs fit in the hybrid bulks.Hot Bodies Lightning diffs and Ofna diffs i know fit for sure.As far as the centers im using the rear dogbone that came with my FLM chassis and im using a UE titanium front dogbone.U cant use the stock center driveshafts with 1/8 buggy gears because the pinion shaft is larger.And besides the stock centers will twist like a pretzel from the torque of a BB.And as far as driveshafts going to the wheels you need to use a good set of cvds or i believe FLM makes a center shaft for the buggy gears that allow u to use stock shafts.Hope that helps and makes sense

DelimaPhobia

But Flm says "Uses 1/8 scale buggy gears" and the Mugen is a 1/8 scale buggy.
And what excactly is Ofna gears? So I can use cvds?
And if anyone has mugen gears in their Maxx, PLEASE post!!!

Josh

firebird02

heres a couple crappy pics of my FLM Maxx

firebird02

All 1/8 buggy gears are not the same.And only certain diffs will fit in the bulks.Your best bet would be to go here http://fastlanemachine.com/PublicPor...5/Default.aspx and get the awnser straight from the source

What Spur/CB combo are you guys using on your BB maxxes?

firebird02

Im using a Strobe slipper with a 51 tooth Ofna gear and im using a Mugen clutch setup.Not sure on the tooth count on the bell.I'll get back to ya on that

Thunderbird93

I have the Traxxas 24 tooth CB and 64 tooth spur gear.
