Top Cat Runner with Mods!!!!!

Post by Mad Racer »

I have been track testing this for a while now with some very pleasing results so far. On its first run i was surprised how good it feelt to drive. Very smooth with fairly good steering. The 13t brushless was so good with strong acceleration and a healthy top end. ( close to a good 19t brushed) Unfortunately i had a tumble on the back straight and herd a loud snap. That was game over for that test session.

I quickly rang Jason ( Bormac) to tell him and he sent up some spares and a few lower hinge pin blocks that broke. He explained to me that this was not a standard Top Cat with a few updates and some of his own mods thrown in when he built it up for me. I metioned to him that it had a little too much on power push (understeer) and a rear anti roll bar might be the ticket . So he also included a new Roll bar kit as well (Thanks).

I have now fitted the new rear roll bar using Tamiya adj ball ends. The rear bulk head was of a Cougar so i had to cut out some of the webbing to clear the bar. Another track test will be scheduled this coming Sat with the other vintage runners. My little track test (at Home) is proving to be alot better with on power steering.

The Mods so far to date are:

Up dated castor blocks (more steering)
Updated Steering links ( more throw)
updated Rocker Arms ( stronger )
updated Rocker leavers ( stronger )
Different rear arms or flipped ( shorter wheel base = More steering)
Rear Anti Roll bar. ( more on power steering)
Gpm rear shocks with losi springs.
Yeah racing front shocks.
Re located steering servo ( just Slightly)
JC Racing Wheels.
Losi Rib front tires in super sticky red compound.
Pro line rear Bowties in M3.

Great Topcat Mark!

My Topcat is very similar. It has been a minor obsession of mine for a few years. Like yours mine also has the steering kit, JC Wheels and new shocks. I chose to go with the Schumacher ultra shocks and a works transmission.

I was all ready to hit the track in August only to see the track get bulldozed the week before and now winter is almost here so it will have to wait till spring:(

Love to see some action shots!

Have you tried moving the battery sideway's? I get good traction and it jumps with no problems. I run a brushless 3.7 with a 5000 lipo battery.
