Sorry srg-bz standard size servos! The bls are those I want to install.

Honestly don't. You'll regret the loss of power going from the BZ's. Have you tried putting the car on scales on all 4 wheels? What's the readings?

My 977 is pretty balanced L/R running Sanwa ERS-962 servos and a xceed rx lipo.
Any thoughts on the Ko Propo BSX2 low profile line? They have up to 18kg of holding torque and are only 48grams...

I would tend to think that this would be an interesting option for those wanting to shave some weight.

Thoughts?

I'd still be dubious. Your putting an awful lot of stress on a servo that was ultimately designed for an electric touring car! I'll be sticking with servo's designed for the job in standard size but hey you guys can do what you want to experiment but its a heck of an investment if it doesn't work. At that torque I would consider using one on the throttle/brake but certainly not steering.

To be honest, your gonna have a very hard time getting perfect chassis balance L/R. Balance will ultimatly be achived by adjusting the preload on the shock collars. Always chose your servos based on application, not weight. At the end of the day, those few grams are not going to keep you out of the winner's circle.

Anyone know if you can use the same starter box mounts/guides for the 748 and 977?

Just ordered both cars but don't really want to buy/carry two lots of starter boxes if I run both cars on the same day.

Also, are the springs between both cars the same?

No you'll need to adjust the starter box each time you change cars. It's not really that difficult once you know what the change is.

The front springs are 23mm long on the 977 which is the same as the 748 front and rear. The 977 has 27mm rear springs but you can use 23mm springs on the rear as well. You'll usually run softer springs on the 748 than the 977.

Finally got to run mine on Saturday, loved it to bits, such a good car, most everything on it is flawless, two speed and clutch never drifted on me once set, was so composed to drive in general.

To be fair I was not pushing it to any limit, new scale to me, entry level Nova Brave, and I ran 16%, but overall the package worked great for my first time out in 8th scale.

There is nothing like a 1/8th nitro car at full chat!!!

There certainly has an epic quality about them, and Serpent created a damn good bit of gear with the Viper, mine is used and has some miles on it, but nothing on it seemed to wear to the point you'd notice within a single meet.

Bugger me though if they don't half chew through tyres fast though.

Depends a lot on the track surface and the shore of tyre used. Throttle control contributes a lot too as an 1/8th car can wheel spin significantly if your a bit of a throttle jammer

my 977 is very good on tire ware at my local track. and goes through tires fast at another track that I race at. so track surface plays a big role on tire ware.

Yeah our track can be fairly high tyre wear right now, it was fine though, I knew going into 8th scale tyre wear was going to be higher than 200mm, or my electric (which also runs foams).

For the 20min final I ran some 37s all around, it was good to drive, and I was getting easier on the throttle by the end of the day/night, so there was enough left on the rims to probably run a qual heat next meeting on them.

I'm saving money on fuel though, 16% through a Nova Brave, two fuel stops in the 20min final, I was getting 7+mins run time.
(I'll be trying the 9mm insert I think based off that)

Tyre wear should be lower in 8th compared to 10th, the down force in 8th means the car should look after the tyres more.

32/35 shore tyres on a 200mm wouldn't last where as they do on 8th no problem.
