Basic advice for construction and maintenance of TRF414 series chassis

Basic advice for construction and maintenance of TRF414M chassis

Changing even just one setting for the TRF414M chassis can completely alter drive performance. To get the best enjoyment, it is essential to strictly follow recommended building and maintenance procedures. The following information will present you with particular modifications to be made on spacers and offer basic rules for maintenance. Make use of this guide when making chassis alterations.

Pay attention to following points during assembly

Attaching screws
When assembling lower deck, on a flat surface, put screws one by one in place and attach them uniformly a little at a time. Make sure to tighten uniformly as completely tightening one screw before attaching other screws may cause chassis to become twisted.

Making it fit like clockwork
When there is a bit of play between parts, you can use spacers sold on the market to make a tighter fit. However, be wary that making the fit too tight can cause hindered movement and make settings difficult. Removing just enough play to create a tight fit while ensuring enough room for setting modifications is the way to go.

Changing position of spacers will change drive settings

Spacers on Lower Suspension Arms
Placing spacers between lower arm and suspension block will affect wheel-base and center of gravity.

Front side of front arm + front side of rear arm: Will transfer center of gravity forward, resulting in tendency for over-steering (standard spacer setting used by TRF).

Rear side of front arm + rear side of rear arm: Will transfer center of gravity backward resulting in tendency for under-steering.

Front side of front arm + rear side of rear arm: Shortened wheel-base (255mm), will result in tendency for over-steering.

Rear side of front arm + front side of rear arm: Elongated wheel-base (265mm), will result in under-steering.

Attaching Spacers to Upper Arms
Despite the fact that spacers are thin, they increase camber angle when attached to upper arms for realizing more grip. Increasing camber angle will also increase roll. Please adjust camber angle as you see fit.

Maintenance

Sustaining a heavy crash or running for extended periods of time may cause your machine to run strangely. Here we introduce convenient methods of maintenance perfect for those times when cornering becomes impaired or when your chassis won't run straight.
1. How to fix warping
The most common problem encountered amongst R/C enthusiasts is warping of the chassis. Place the chassis on a block so that wheels are not touching the ground and shake chassis. A rickety sound denotes warping of the chassis. Fix upper deck while loosening all screws. Then tighten screws uniformly, little by little.
If this doesn't solve the problem, there's the possibility that the bulkhead is twisted. Loosen all screws attaching bulkhead to chassis and re-tighten.

2. Adjusting Tires
After re-affixing screws place the machine on the block once again and look at tire height. Are the left and right tires at different heights? If so, you may have problems running your machine in a straight line, or turning as you want to. Find the left and right 3x12 screws used for adjusting rebound stroke and adjust tightness so that left and right tires are the same height.

3. Re-check clearance
Place your machine on the ground once again and re-check clearance, rebound stroke and camber angle. Re-adjust if necessary. If abnormal running persists, there may be a problem with parts. These parts may need to be replaced.
