The motor plate and lay-shaft mounts being separate pieces, if the motor plate is not screwed into the top deck, the chassis flex will make it move independently from the lay-shaft, changing the gear mesh. I had a 64 pitch RW gear strip going through a high speed sweeper at SoCal once because of this. Even if the screws are not good and tight, the flex can cause this to happen.

As for what brand of spur gears, I like the RW gears and the PRS gears. If you're using anything other than the stock gear, make sure you notch the pulley where the screws go so that you can mount the screws in the inner holes on the adapter.

Thanks for replying Jon. I have checked that and they are all tight and sqyare. Plus the spur is spinning out of round when on the bench!!! It is soooo frustrating!!!

By the way, do you guys use the 64dp gears or do you stick with 48dp gears???

Clint- hehe, that's where I had some Rit Dye drip off some parts on the towel.

Dirtydog- if the spur is spinning out of round, the only other thing I can think of is that the alloy adapter is bent if your layshaft is straight. I prefer 64p gears. My cars are so quiet running 64 pitch and you have a much finer control over your gearing.

What are the main differences between the two car setups (foam vs rubber)?
Foam tyres on tourers are'nt so popular in the UK.

just an idea on my part.. if the 3800's simply wont fit, try using a dremel to slightly enlarge the slots. I took my time and got them to fit an older bmi chassis. I also took a different route than the strap: since I still use a variety of batteries(3300, 3700,3800), I found that cutting a length of velcro tape has made it easy to use different batteries. It comes in a roll and you just cut the lenghth you need. Pull it tight over the batteries, then slide it so it is angled in the slots of the bmi (just as the stock strap has a slight angle). So far it has worked without issues. Ofcourse strapping tape works well, and like the velcro wont give any tweeking issues.

My setup up on my Foam spec car isn't for foam tires. I run that car at SoCal (indoor asphalt with rubber tires) because it's really high grip and the stiffer chassis seems to work better and be much more responsive. There are quite a few differences between the two cars. Thicker chassis and stiffer, thicker top deck, lower roll centers, no riser plates under the diffs, different shock towers with different shock and camber link locations, different rear toe, etc...

Foam tire cars usually are very stiff. Stiff chassis and suspension. The cars usually have so much grip that they usually are trying to take grip away to get the car to flow through the corners.

roadrash: The original BMI chassis was cut for 3300's. Also there are different battery straps from the 3300 era to the larger cells. How old are your chassis and strap?
I'm not sure, they fit with straping tape. I am just going to run my 3300s.

Is the pack hitting the posts? That'll happen no matter what chassis or strap you have. Take a dremal and put a small notch in the post where the cells touch. This will allow them to sit nicely in there.

PW is at Superior testing for the state race right now. Check in with us early tomorrow. There are a few very small changes that you could do in 10 min to get your EC dialed for Corally Land.

Is Superior infested with Corally's like SoCal is? Well, Corally's and T2's.

The kit bearings aren't ceramic but they're a new design over the old blue seal ones. Much smoother and much tighter tolerance so they don't build up slop so fast. Ceramics are or will be (not sure if they have them yet) available for the EC through Schumacher though.

Nemesis - The kit bearings are high grade stainless. We have full EC ceramic kits and individual ceramic pairs of bearings in all necessary sizes.

Jon - Superior Hobbies is the home of Specialized R/C the Corally USA importer. Its all good though. We are all really good friends since we have been racing together for over 10 years.

Its going to be a good race. Tosso is there and so is Jared Scott from Xray.

Ah. I see. The Corally guys around here are all pretty cool too. I was trying some different stuff at SoCal last week and Edgar Fialos helped me out a bunch to get things working right.
