Anyone can turn a wheel on their radio faster then their servo, our hands are much quicker.

BLS451 is the best for 10th steering and 8th throttle/brake, get the BLS452 for 8th steering. End of story

Our get the best servo on the market... Airtronics 94358/9 200oz in at .10 I run them in my 8th scale.

Thanks very much

I recently switched to the BLS451. Never been happier.

Futaba advertises a faster response time on their BLS series of servos than the competition. Don't confuse response time with transit time. Response time is how fast the servo can take the input from the receiver and turn the servo horn. Transit time is how fast the servo horn can get from point A to point B. The BLS451 is so much smoother than any other servo I have ever used in 13yrs of racing. Hope this helps.

Airtronics 94358/9 or 361 definitely look awesome. But they are not digital. Does that mean the Airtronics has less resolution, not as smooth, or doesn't center as well as BLS451?

Does the Airtronics servo works well with Futaba 4pk ratio and receiver?

Also, I just looked up Airtronics 94358/9 or 361 on Tower Hobbies and all 3 of them are marked as discontinued. Is that true?

I would definitely go with the 451 over the 452 if you can afford it. Being brushless, these servos last a very long time and as you improve you will definitely love the faster speed the 451 provides. I have just finished putting 451's in ALL my cars; B4, T4, B44, RC8, and SC10 and I made this decision after trying many servos from all the manufacturers. The speed is there, the torque is enough for anything but truggies, but most important is how accurate and incredibly smooth they are.

I have 3 x BLS452s and actually I think they are really great servos, even as compared with older Futabas. And they center really well without much play at idle position. The only thing is they are a little too slow. That is the reason I am considering switching to 451.

I use 8800s's in my 10th 2wd applications, AE 1313's in my B44 and RC8. All have been great servo's so far. Over a season of use on all of them. Indoor and outdoor.

Default VCS2 Shock upgrade kit

Has anyone used this upgrade kit on the B4? Any tips on installation? Was suggested by my LHS, who has yet to steer me wrong.

Actually I am also considering the Orion. The spec looks awesome, but I am not sure if it is as smooth, durable and centers as well as BLS451. Can you please share more of your experience with the Orion? Which model do you have?

I tried to turn the transmitter steering wheel faster than the S9551 servo on my friend's B4 full lock to lock, but I couldn't. But I can quite easily turn quicker than BLS451.

Default basic set-up question

Basic set-up question...

Just finished building a Factory Team B4. Stock recommendations as per instructions. Put the LiPo in the more forward position.

Not getting enough steering. Do I need to add weight forward? Adjust ride height? Oil weight? Shorten wheel base?

Running on a relatively smooth, high traction clay track.

Any suggestions would be appreciated. Thanks!!

Basic tyre theory says that less weight gives you the best traction, but a heavy sprung mass (the chassis) gives the best performance through bumps. The change from nimh (heavy) to lipo has meant that everyone has had to re-work their setups to get a good balance of handling and bump traction.

If your track is relatively smooth, run at minimum weight with Lipos if possible. The car feels much more responsive and grips better (tyre wear is better too). You will need to run a softer setup (see the latest Thielke setups on rc0.com - these are a good starting point).

Increased toe-in will make the car accelerate straighter, and the rear slide a little less in corners, but it can 'snap' a little more at the limit (basically, you are taking the tyre to the limit a little quicker). Usually, tyres need a little more slip angle with less weight, hence why the lightweight lipo setups have been using them. I have found if the track is a slippery, point and shoot track it helps; if the track is grippy and flowing, stick with the standard 3 deg.

stiffen up the back end a little bit. this will give you more steering on high traction. If using black springs in the back, then use green. If using green already, then use silver. This will also make you jump higher. Hope this helps.

Interesting, because the claimed speed of the BLS451 is faster than the S9551 (0.10 vs 0.11). Is it possible that the setup that has the 451 in it set up so that all of the servo's travel is being used while the S9551's setup only uses part of it's available travel?

I have a BLS451 in my 1/8 buggy's steering and I have never seen a servo this fast before.

57..where are you looking for steering? on power? off power? going in to the corner? coming out?
If your just looking for more steering everywhere then start looking at tires.
