Custom Trail Finder 2 Chassis based on SCX10 Carbon Rails / Wheelbase 11,2" (284mm)

general description

• The chassis geometry is 100% identical to the original RC4WD Trailfinder 2 (11.2").

• All mounting points, bumper mounts, body mounts, shock mounts, and leaf spring hangers are 100% RC4WD compatible.

• The Gearbox. Only difference is that I'm not using an R3 gearbox, but an LCG gearbox with an Axial SCX10 bolt pattern.

• I use the one from INJORA, but there are countless alternatives (DLUX FAB clone with AXIAL hole pattern) on Amazon, AliExpress, Temu, etc.

• The free space at the front of the chassis is used for batteries or additional servos.

• If you use a 540 engine, you don't have to cut into the interior.

• The leaf spring kit is also available from Far East shops. It's labeled for Tamiya or D90. You only need to modify the hangers minimally to get them to the RC4WD length (see picture).

• The axles are very high-quality alternatives, much better (cheaper) than the originals. Build quality and appearance are better than RC4WD. You can also find them in Far Eastern shops.

• The Rails are original TFL Racing parts, belonging to the T10 Pro chassis, a very high-quality SCX10 Gen1 clone. Now they are available as knockoffs in the usual Far East shops for around €15.

• Almost all holes are designed for M3 screws.

• Many screws are screwed directly into the plastic. Some require nuts.

• Everything was printed in PLA+ with 25% infill and 3 border lines. Using PETG or ASA will make it much more stable.

• L and R mean left and right.

• skid / Various mounting points for the gearbox. Depending on axles, gearbox size and motor orientation.

• akku_servo / The right-hand space is the original RC4WD servo mounting location, the left one is optional.

• shocktower / The front allows the shock absorber to be mounted in front of or behind the axle. The rear shock absorbers can be mounted the same way; you just need to rotate the rear shock tower.  Attention, the optimal size for shock absorbers is 90mm.

• support / For reinforcing the bumper mounts. The rear one is also the original body mounting point.

• shackle_under / The original rails are wider, therefore the parts must be placed under the steel leaf spring holders. The dots must point forward. 1 is the front chassis, 2 the rear.

• hanger / Mounting points for the leaf spring hanger (I use M3 screws with 4mm sleeves over them, but M4 screws or M4 shaft screws also work).

parts description - drilling_templates

• drill_front & rear / For the steel leaf spring mounts, M3 holes need to be drilled into the chassis; these drilling templates are for that purpose. I've included templates for the front and rear. Attach them to the rails with M3 screws and drill through.

parts description - body_mounts

• Body mounts for all RC4WD bodies that fit the 11.2" Trail Finder 2 chassis.

• There are also versions with an offset of -6mm (minus6) to make the look more scale.

parts description - bumper_mounts

• All three variants of the RC4WD bumper mounts. Naturally, they are not as stable as the originals. Therefore, they are additionally secured to the support chassis parts with three M3 screws.
