HL bulldog, how much weight to add?
 
just curious if someone could tell me how much weight to add to my walker bulldog. all my electronics are in the turret now, and i added a larger somewhat heavier speaker to it that located in the front. i am noticing that when i try to climb up anything that is around 2 inches high the front of the tank points nearly straight up and the tank just sits there spinning the track. id like for it to tip down on the front and be able to get up onto what im climbing. is there a specific weight that i should add to get it to tip down without overloading it?

How large is the speaker exactly?

at best guess its 2.5" across the cone, 2" tall from magnet to the top. i sealed it into a section of a pringles can as a bax and it just barely slid into the pringles can. the bass it produces is amazing. the machine gun sounds awesome, along with the cannon and motor start up. the higher pitch of the running motor isnt as loud but it does sound better than the stock speaker. it is a JBL speaker that i took out of a old computer speaker. it was from a compaq presario desktop computer and the speakers were made to lock onto the sides of the monitor. ill see if i can find a pic of the original computer speaker i am refering to

If you have metal gears in the back, you're looking at about 16 oz.  Best way to get it right without a scale is to use 1 oz lead fishing weights.  I would also get a piece of 1/2" x 1" wood and set the tank on its center roadwheel.  Work the center of mass from there.  You want it to either balance or just tip to the front based on what you've described.

Not sure what kind of set-up your running but 16oz is almost twice what I'm running at 9oz.....I balanced mine just a tad front-heavy of perfectly balanced. I just went to my buddies tire-shop and got some adhesive stick-on wheel weights which were real nice as they were stamped in 1/4oz increments and icould just break off what I didn't need and also trim them to fit.

***remember***...the further forward you place the weights the less you'll need, thats why mine are all stuck to the very front of the tank..
