Default RC10B4.2 - Which 11.1 v fits ?

Hey folks new to this forum, just bought an RTR RC10B4.2 off Tower. Excited to drive this, I remember long time ago this was the RC to have. Just getting back into this now so felt this would be perfect for me.

Question - has anyone successfully installed a 11.1 volt 3S battery into this ? If so, which fits and which would you suggest ? Im looking for 5000 mah + capacity for the reedy 3300 kv motor and esc. The stock esc is rated up to 3S with a 3300 kv so should be ok. Another option later down road will be swtiching esc and motor to higher kv, but for now just looking for a good 11.1 to use with standard motor and esc.

The stock battery size is 47mm wide x 140mm long x 24mm high. Could do 25mm height if I shave the battery strap foam down. Or much higher if I figure out another battery strap altogether, provided length doesnt exceed 140mm.

Also, does anyone make a full front bumper that protects the wheels for this ? I know with how its currently built I will clip the front tires and end this thing, a front bumper would go long way toward saving it.

Thanks!

Why would you want to use 3 cells? 2 should be _more_ than enough.

But if you must, check the size for a normal 2s competition hardpack and compare it to the 3s you are looking at.

It's more than likely you'll need to mod the battery brace to accommodate a taller pack.

Well I have to buy a new battery pack anyhow to get something 5000 mah + so i figured might as well just get 11.1v to see what this can really do. I know I would have to use the 2s pack for racing but for general track practice and bashing, 3s > 2s

Anyone know of a battery strap mod for this?

Reedy 4500 11.1V 3S - Will not fit, too tall.

http://www.smc-racing.net/index.php?...product_id=182 - wont fit
http://www.smc-racing.net/index.php?...product_id=159 - wont fit



http://www.teamtrinity.com/shop/inde...product_id=381

what are dimensions on this ?


I saw some floureon packs on amazon. not hard paks but they do have 3s with the right dimensions, although only a 3000 mah capacity. I ordered 2 as they were only $40 shipped for both, have some good reviews on amazon and 1 person even said they are running in a B4.2.

Anyone know of a battery strap mod to allow a taller hard case battery ?

The esc can't handle too much of 3s. I wouldn't use it. Maybe a high discharge 2s but definitely wouldn't use too much 3s

The speed control is rated for 3s @ 3300 kv. Why wouldnt you use it at that ?

I picked up the RPM front bumper. Sadly though it doesnt even over the front tires so if you clip 1 it will destroy the front end all the same

Someone needs to make a carbon fiber strip bumper that goes all the way around the entire chassis and protects everything (like a go-cart design). Wonder why that isnt offered. The T-Bone bumper seems pretty useless. The RPM a little better but sheesh why did they leave the wheels sticking out unprotected. Thats what you are going to hit and its bye bye a-arms ect...

The t bone bumper allowed the chassis to crack in half on ours after hitting a pipe. You are better off using a 2s lipo and a de racing chassis brace. With a smc 6500 2 s...my son is tired of driving the track before lipo cuts off. While the t bone bumper stunk on our b4.2 it rocks on our b44.2 . his addition to his collection is a 44.3. The 2s 6500 smc fits perfect in his b4.2 rtr.

Also switching to 23t pinion but yeah it's really only for street and I realize only use full throttle sparingly. I'll feather throttle from start and may adjust slipper clutch.

Will give honest review once it's here

Maybe a higher kv motor would be better but I'm hoping with 23t it will calm down enough combined with light throttle on accel.

Next step is to replace speed control with better and go up to 6k+ motor to drop the torque

all i can say is WOW. The 3s batteries work great and really gives the buggy tremendous punch. Huge speed improvement. I think I will switch to a 25t now as it really has enormous torque off the line and is difficult to control. I really need to be light on throttle, but after 1st 10-20 feet you can punch it and this little buggy flies! I recommend this.

Now I need tires !
