RC10B4/T4 Forum

That setup is definietly different than others I have seen lately. A few questions though for everyone to discuss and give their 2 cents on.
Why the non-milled motor plate?
Why plastic hinge pin brace and plastic bulkhead?
And why back to running weight in front of transmission and in the rear triangles again?
This can not qualify as a 'light weight' setup any longer and instead is now the new standard for 'Lipo Setup' that still uses weight to better balance the car?

Before I switched everything over I had to add 1oz to the receiver side to balance things out L to R. After the switch, L to R balance is dead on without adding any weight at all.




i all new to the b4 forums but have had a b44 which i just recently sold..this forum has great tools to use and apply. i have a few questions though
i went to the track today and was running the car and noticed that the car pushes a little in the front off power.do i need to raise the ball stud to regain the steering or just leave the washers out completely? also i just put the sxx stock spec in my car and love it!! the only thing is that when i ran 25t pinion and 78 spur the car came off pretty hot after about 10 min or so. the settings are at the default on the spedo.all i did was enable the lipo cut off. any suggestions on what pinion i should be using? motor is a x12 13.5
any help would be greatly appreciated i have a big race comming up on sat and would love some input high grip track as well..
just looking for my car to hook up nicely associated b4 ft carbon chassis w/reedy 5000 2c lipo

I'm looking into purchasing the T4.1 Brushless/2.4 RTR kit, and was wondering if someone could list out the differences between a regular T4 and the T4.1?
Thanks in advance.
Thanks in advance.

Anyone running a "heavy" set up? I got a new T4 on the way and I am thinking about adding enough weight to fully make up for the lipo battery to give it an old school feel.. I am just not what impact this will have on gearing. I race on indoor clay if this makes a difference.
front of the trans, no more than that though. Works fine for me
as I have always liked a heavier feeling car. I run my T4 at minimum ROAR
weight also. Same results.

I have a T4, with a 07' sphere comp, 2S lipo, and a X-12 13.5. My motor is also running hot. I geared it at 24/81, and ran about 6 minutes. Will brushless motors get hot if you gear too low? I am a long time racer, but new to brushless technology. Speedo settings are all mild, no binding in the drivetrain, no advance timing on the motor, tranny not slipping, and slipper set correctly. What gearing do you recommend? Is there anything else I should check? Do the LRP X-12,s typically run hot? Any help would be greatly appreciated.

They can get hot if you are undergeared too.Ive use this site a million times to help with gearing.Not alot of motors to select but a real great tool.

Tony as a realative newbie. This is surprising to me. I would think that if you add weight say to the front you would get more front steering because their is more weight on the front tires? Am I wrong? Thanks

For me, if I were to add weight to the front, it will give me more off power steering and less on power steering. When you aplly the throttle, it transfers weight to the rear tires.

Adding weight to the front can add more steering off throttle to a point but usually causes a push. The Losi guys are running a TON of weight in their front ends, I tried it, didn't like it. With the heavy front the car feels dead and lazy up front to me (we're talking Losi here).
A good way to get a better understanding of how it works is to play with battery position in practice. When you move the battery back you will probably find the car steers more/rotates more off throttle. Seems backwards but it's kind of a pendulum effect that overwhealms the available side bite.

Imagine an oval car going around in circles... if you add weight to the rear you'll gain steering because inertia is pushing the weight towards the wall. Same with the front.
