Rebuilding my serpent 720 radio controlled car


Ok so decided to dig out my r/c car a few years ago i raced these at club level and at national level and the highest i finished was 9th nationally and 4th in club level.. It was very tough due to work and cost to run them for a season to be competetive. Putting this aside i said id give it a bash this season which should start in april or so. The club and track i was at is the only onroad track in dublin. Www.orcaireland.ie .above is a picture of the car stripped down its a serpent 720 1/10th scale

This is a picture of the front and rear differential the one open gives you an idea of the internals of a diff it uses 30,000 wt oil. I found a leak on this so i had to fix it. The seal is a rubber o ring and was pinced so fluid was leaking out. Takes about 20mins to clean and refill then seal up.

Next this picture is a picture of the shocks on the car they need to be maintained alot. I use 40,000 wt in the rear and 30,000 wt in the front they are fairly simple to break down and fix. I have a tool that when the shick is open and old oil removed and new oil installed you put the four shocks in a vacuum chamber remove all air and in doing this the air is drawn out of the oil due to the negative pressure to give you the best performance when re-assembled.

This is the rear diff and belt re-installed in the car.
