Extending the wheelbase on RC cars is nothing new but I've yet to see anyone document this for the WL Toys 144001 Thus, I've written this article to show you how to do it step by step. There are a number of benefits, not least of which is straight line stability. The good news is that this requires no extra parts and it only takes about 10 minutes
Basic theory for extending wheelbase
Changing wheelbases has long been something you could do with race-spec RC cars in order to adjust for track conditions. Generally speaking short wheelbases allow for faster turning (sharp corners in particular) and longer wheel bases allow for better straight line stability. The 144001 is overpowered for such a small car (especially if you upgrade to brushless) that any increase in wheelbase is welcomed ESPECIALLY if you are looking at speed runs where straight line stability is crucial.
Extending the wheelbase on a WL Toys 144001
The good news is this is very simple on the 144001 and it's free - no new parts are needed and so far as I can tell there are no compromises to the car. In fact there are slightly more benefits than I first thought:
Easy right?! I've checked over the alignment and everything seems to be fine - the shock sits square and doesn't foul on anything and the dynamic suspension geometry remains nice and neutral. The only disadvantage I can see is that you can no longer fit an LC Racing Anti Roll Bar. This is a fairly minor disadvantage - anti roll bars are typically only used for track racing. This mod will add an extra 5 to 10 mm of extra wheelbase which is small but significant. But for a fast and free mod? I'll take it.
For those keen eyed readers you can probably figure these changes have been made for my new speed run car, however I will roll out to my other cars in time as the benefits well and truly outweigh the disadvantages on these small cars.
