Here's my 1st entry. It will be competing in the 1/25 Hot Rod class.

Used the model kit chassis. Helps to get the body properly mounted... :D

Here you can see that I hogged out where the motor is, and simply glued the motor mount to the chassis (using Goop)
You can also see that the wheelie bars are also glued to the chassis.

Here you see I attached the drop arm and the front axle tube to the chassis (Goop!!)

The 2 screws you see on the bottom of the chassis screw into the model kit interior which is glued to the body shell. This way I can remove the chassis and have access to the motor. You'll also notice lead weight stuck to the underside of the chassis. As it sits in these pics, it's 6oz (our club rules), so I can remove an ounce before sending it to Todd's... :auto-driving:
Rear wheels are H&R narrows, tires are Paul Gage narrow slicks.
Front wheels are WRP Halibrand style (part# W-06). Tires are urethane, molded from kit tires
Pirhana motor (per the rules) currently geared 9/31, but will probably lower the ratio for Todd's track (more info on that coming)
