Just built my 05 for this weekend's big race in stock, on carpet using rubber tires. My friend built on at the same time for the same race.
My first reaction is this thing is quiet! It is even quieter than my 415.
You had to strin hard to hear my car running even if i was the only car on the track.
Second reaction is this car is smooth and carries corner speed well.
We were on pace most of the weekend to carry TQ but there are some problems with the car. The plastic diff outdrives do not take punishment well.
The fix is to dremel slots and add a ring around the outdrives.
The cars were built basically stock except for the lightweight suspension. I used all steel screws, and even used the plastic shocks.
The final result for me did not bo as well as I liked but my friend's 05 finished 1st. Agains all commers such as TC4, Pro 4, X-rays and even a 415MSX.
Some people could not believe the car is a tub Tamiya.
I am very impressed with this car's potential and cannot wait to see what it can do if I put this thing on a little diet, stiffen it a little(not necessary for stock), and do battle in 19T class.
