I was told that the 705 is a foam only car. I run the impulse pro with rubber slicks now. I have no problems with gettting parts. My LHS has tons of serpent parts. I also run the vteq 2002. Matter a fact my LHS brings an enclosed trailer full of serpent parts to the track.

It's not so much that it's a "foam only" car... The suspension changes that have been made to the 705 (and the Pro before it) were designed to optimize the car's handling with foams. You could still put rubber tires on it, but you'd probably have to alter your setup significantly to optimize handling. For sure, you'd probably want to replace the 705's one-way with the Impulse's diff, and either soften or remove the anti-roll bars, depending on the traction available at your track. I know that when I first started using foams on my Impulse, I HAD to install the anti-roll bars. My car felt on the edge of traction rolling !!!

Unhappy Solid diff probelms

Hi Guys,

I'm trying to fit the solid front diff 801240 and the geardiff adaptor 801393, but the width of the solid diff + adaptors is significantly smaller (4-5mm) than the standard one-way diff. And as I'm using the FC blocks, my drive shafts fall out It was already quite tight with the one-way diff, but not it doesn't work at all.

Does anyone else run the solid diff with the FC steering blocks? If so, do you have a solution to this problem?

Cheers, Mark.

If I'm not mistaken, I believe you have to use the Impact/835 front driveshafts (808220), which are a little bit longer than the Impulse/705 driveshafts(801220)... Anyone correct me if I'm wrong

Just take a driveshaft to your LHS and compare your drive shaft with the Impact one just to be sure... Yes, I know - Serpent really needs to improve their cross-references when it comes to what parts are interchangeable or not.

Thats correct!
Impact driveshafts are longer then Impulse/705 drive shaft.

Yes, I am using it at the moment. Nizee, Punisher and I believe Pit-racer is also using them.

Yes, the punch is tremendous. Set the end float about 0.4 to 0.5mm for smoother transition of the clutch and easier on your thrust bearings too. Set the spring to tighten down hard and loosen the spring tensioner nut on the track until the car engages nicely.

Like what TurnNburn mentioned, you need to reset the settings. Rubber tires will require you to set the springs and suspension very soft. The car needs to roll a little to get traction. So the shocks should be at the lowest possible angle (bearing blocks) and no 7 mm aluminum spacers on the rear uprights. A low roll center in the rear will make the car roll more.

Ask Proficar403 (Arun Misra). I believe he posted quite a good setup on mytsn for rubber tires.

You caught me off guard on this one Mark. I mentioned that I have not used front solid axle before in my car or front diffs for that matter. What TurnNburn has suggested is pretty neat in using Impact front doggies. But I believe there should be other methods. Could you space the diff adapters out a little and lock it further out?

I might try and ask a buddy of mine how he installs his front gear diff + pro diff adapters (I would assume that the assembly is of the same length as the solid front axle with the diff adapter) with the FC steering block. I think pokemon also uses the same setup (front gear diff with FC steering block).

Sort of, but there is a grub screw in the diff adaptor and when I place the diff adaptors further out, then the grub screw doesn't have contact on the full length of the diff's shaft anymore - I'm afraid that the diff adaptor may damage the diff or come loose.

I would be interesting to hear how others have dealt with this - I'm ordering some impact drive shafts to see if this'll cure the problem.

Thanks for the help, Mark.

I cured mine the easier way. I just changed to the Yokomo front hubs and use Yokomo axles and UJ's in the front. The standard Yokomo hubs are the equivilent of the Serpent FC hubs and Yokomo have still have an FC hub in reserve again. Tons of steering, 1mm higher rollcenter and no doggies falling out all in one package. What more can you ask for at a fraction the cost of the Serpent stuff for the same job.

You do still have to use the Yokomo servo saver and 190mm pivotballs though. But it works great and is a lot lighter.

Do you have the part numbers for those bits? I'll keep a note of this just in case the longer impact drive shafts don't cut it.

Cheers, Mark.

Yokomo part Nos for conversion

2x ZE-008B (2 sets of 190mm pivot balls) $12
ZE-415F (set of front hub carriers $8
ZE-542 (front one-way drive cups) $11.50
ZE-200 (Servo saver parts) *$12
ZE-006W (200mm Wide Steering Tie-Rod Set) *$7
ZE-010BW (200mm Wide Dogbones $9
ZE-010AF (Front axles) $16.50

Also require 4 off 10x15x4mm Bearings for hubs

*You should be able to drill out the hubs to accept the Serpent Steering arms and servo saver. This will save you a bit.

These are YokomoUSA prices which are normally 15% or more higher than shops to force people to promote the local shop.
