I bet it is a et410.2, with a longer chassis and different body mounts and bumpers. It should share 95% with the eb410.2 and et410.2. It will be a lot light lighter then the sct410.3. This is what we did with the Cobra chassis, then later with Prostar. Prostar stuff should be better. But with official body mounts, that is cool. Took them long enough.
