That is the way to do a prototype... one piece at a time. When you get all the geometry right let me know. Maybe I can machine the part for your from Carbon Fiber and Delrin.

Haha, I actually told him about you. I want you to make a motor mount for me.

Thats a good idea too, even vent holes in the tires can help if you do it right.

Badassrevo- Eh he's on my ignore list now lol Since he has been posting alot of wierd stuff. I don't really have a way to convert the axles and such to be able to mount 1/8th buggy rims.

Matt,
Yep thats what I have been doing for the last 6 years. It all started when we did a eletric unit with motors in 2nd grade after that I went to goodwill and garage sales on a hunt for anything that I could take apart and rebuild or simply SMASH lol

First of thank you for your long post,opinion,and help! I do agree that the tires I have now are pretty heavy and big. Though I find them pretty soft . I choose these tires because they are what I have lol Plus I heard they are great basher tires. I would probaly have to agree. Yes they are a bit big and thats why I ordered some Proline Step Pins. How do thoughs tamiya's do for traction? They look like they have pretty shallow tred. I will definatly look into thoughs next time I need tires. Oh yes, I do have vent holes they are just a little hidden


I just ordered everything I need except the g10 and some small parts. I will order the G10 today. Stuff should be here in a week.

You can get some 14mm hexes from www.rcproductdesigns.com and some 14mm to 17mm adapters from www.crazynutracing.com

Thanks for the links. Yea I guess I could get some custom made or just make some myself. Not sure how it would look with them on though. I will think about it next time I need some tires and wheels. It not my main concern right now since at the moment I have the tires and wheels figued out. Peace Ethan

Cool. Well I got the suspension parts in yesterday along with tires ,and some random parts and my top secret surprise lol . I have the suspension all planned out. I also finished the a-arms and painted them. They look good. The bad news is that I had to purchase a book for school so I wasn't able to order the G10 though I ordered it today.

Well here's the story about the g10. I ordered some .125" (1/8th" or 3mm) sheet 12"x18" I wait a week and pay $18 for shipping which was a bit crazy. It gets here and its .188" (5mm) thick. Way too heavy and thick for a double deck chassis. So I call them and they said they would send me another sheet. So I waited another week and it came today. I soon was faced with the reality of how hard this stuff is to cut. I put in my thicker blades on the scroll saw and I start cutting it. I get about 1 or 2 inchs in and the blade becomes dull enough where it won't cut anymore... errr. I exspected this but I didn't think it would be this bad. I thought maybe every 6 inchs I would have to switch blades. So I started cutting with a circular saw and that is not very easy to cut with at all. But I think for most of the bottom chassis I can use it. Its going to be hard but Idk how else to cut it. The problem is ,is that I have no clue how I will be able to cut the upper deck.. becuase I can't use the circular saw much. Any ideas??

cutting oil will work wonders in most situations, it makes a surprising difference. im not sure how effective that would be on G10, did you try using super fine teeth count blades with the scroll saw?

I tried some finer teeth and it worked alittle better. I will experiment tomarrow and look into cutting oil. Thanks

Try getting a REMGRIT GJ-2 sabre saw blade (or something similar to fit your scroll saw). These have tungsten carbide grit brazed to the cutting edge of the saw blade. Here is a link to a catalog where they are listed:

Go to page 19.

Thanks for the link..
Haven't updated much though I have been working alot on it. I cut a lower chassis out and spent alot of time sanded it all down all to find out that in the rear where the spur gear goes through it I cut it too thin. After some thinking time I decided to take a chance and use the rest of my G10 to make another chassis. I made that today and it came out great. I have offically fallen in love with my Jigsaw. The blades last FOREVER. I mean I cut 2 whole chassis's and a upper deck with one blade. I also never knew it could cut so well and easily. I also cut a top deck for it today and I barely touched my scroll saw. I gave the upper deck a sorta sharp gothic look. Right now I have the diffs mounted on the chassis and the upper deck on.



I am far from done and the list of to do's stands

-Make Chassis Stand offs
-Make motor mount
-Make new a-arm mounts
-Drill holes
-Finish battery strap system and slots and standoffs.
-Make Rocker mounts
-Make shock mounts
-Buy and install Push Rods
-Make Bumper mount
-Make Body mounts
-Mount everything
-Paint lexan
-Dye wheels?
-Take Pics
-Install Electronics
-Take Pics
-Make Video

Wow I have alot to do and school starts this week and I have soccer everyday. Hopefully by the end of the week I will have it all finished. Maybe by next sunday and not sure when I will get the video done. But I will keep you all updated.

Also I have a clue for the surprise I have for you all:

"I like it inside out,not outside in"



Peace Ethan

That looks great. Looks like you need to sand the top deck though right?..
