If you are looking to get the new Team Raffee Co. Defender bodies, getting the TRC Chassis Set (TRC/302216) is a must. Here's why.
The Team Raffee Co. bodies are slightly wider and longer than the RC4WD body, and is too big to directly fit onto D110 chassis (RC4WD or Boom Racing). This new TRC chassis set directly bolts onto the D110 chassis to extend the rails and match with the wider front and rear bumpers, as well as wider body posts. They include the following:
To fit the Team Raffee Co. Defender Station Wagon #TRC/302214 and Defender Pickup Truck #TRC/302215 onto existing D110 rigs, this chassis set which includes rails, front and rear bumpers and body posts is a must.
This is a direct bolt on for D110 rigs.
To demostrate, the above photos shows a Boom Racing D110 and installed the TRC Chassis Extension set to fit the body.
To conclude, the Team Raffee Co. Defender bodies are wider and longer than the RC4WD D110 body. If you already have a D110, getting this chassis set means you can directly swap your exisiting parts out and replace with the longer rails, the wider front and rear bumpers and body posts.
