Is the start gate for the Big Rig track in its normal position for a Best track with the start end extended to accommodate the longer truck or is the start gate moved down the track and the start end is still at its normal height of about 4 feet ?
What is the maximum weight a stock BSA Pinewood Derby wheel can carry before the weight starts working against you ?
Thank you so much for your assistance.

It is an extension that is mounted to the back end of the track. Start gate remains in its normal position.
Awana Grand Prix and Pinewood Derby racing - Where a child, an adult and a small block of wood combine for a lot of fun and memories.
That means a lot of weight can be placed 19 inches behind the pin. The total weight of the truck is limited to 25 ounces. A truck can be built very light. It looks like a lot of testing is in my future.
Always open for suggestions.
Per The Best track web site..
The Best Track Big Rig Extension is 12" long .
The normal Best Track ( setup for the cars ) from the back end of the track to the start pen is 8".
So with the big rig extension on the track you would be 20" from the back end of the track to the start gate.
My ignorance is showing. I should have checked with Best track, I'll get one ordered. That additional height should make considerable difference in speed.
Think of where that 12" extension is going to put my COM. The rules for the Class "B" truck are very lenient. Balsa wood is very light. Remember when Doc Jobe explained the "Center of Mass Effect"? It is illustrated on Page 40 of Doc Jobe's Big Green Book, The Physics of the Pinewood Derby. It is explained using two Perfect cars. We are racing our COM's. Probably when you start slowing down I'm still increasing speed. The track is giving me 36'10" for science to help me. What would happen in a race against your car if my truck was limited to 5 ounces? Science would give me the advantage. Following the rules, I will be able to use an amount of weight and place it anywhere on the truck. The timer will tell me what weight position and amount of weight is the Best for speed.
One more thing. The rules do not require you use a Diesel engine or be Road legal. I have ordered a "Blown" Big Block Top Fuel Dragster engine. Money is no object here.
I have no belief I will win this race. The one who will win is the one who follows science the Best and walks into the race the morning of the race and is using oil for lube. I am interested how graphite will do against the oil vehicles.
I hope lots of folks build a Class "B" Big Rig and comes to the race. Maybe we can help the Class "B" truck group grow in number.
