You might contact [email protected] to see if he has a better shipping method for you.

I tried to keep the scheme simple but make it stand out. I love that fluorescent yellow. :nod:

Looking good! Won't be able to miss that on the track. Time to get dirty!

Thanks Harold. I rubbed the squeaky clean look off of it last weekend. :nod:

I opened up the fender vents yesterday. I used a 5/32" straight fluted drill bit to drill a hole at each end and then connected the holes together with an Xacto knife. It isn't perfect, but it should be functional. I figure that it removes 3 square inches of material from the body.

I know you used CFD to design the body. Did you try running it at different angles of attack? I don't see forward drag as being as much of a problem as parachuting where the truck launches with a nose high attitude. Combine that with the fact that most 2wd SCT have a 60/40 weight distribution and you can how the air getting under the front of the body can flip the trucks over.

Coming from my high power rocketry background I'd like to see a body with a longer bed and more vents in the hood. That should move the center of pressure back closer to the CG.

Chris,

We ran the body at different yaw angles (slip angles) and different angles of attack (attitudes). We also tested quite a bit to verify simulation results and ensure we had achieved the best balance. You'll really notice the extra stability in the fast corners. Have you tried running the front spoiler? That also helps with reducing the amount of air that packs up under the hood. With your rocketry background I'm sure you would appreciate some of the other things that we learned in CFD and testing. I'd be happy to discuss this further with you in confidence. We don't want to give away all of our secrets. :D Also don't want to upset the RC Tech gods with material that could be construed as advertising (our stuff was just designed to work better without cutting it into swiss cheese and we're a bit proud of that).

All the best,

Harold, Method RC

Harold,

Thanks for the offer. There's no need to spill your secrets. I was just curious.

I am going to try two things this weekend. I cut our the spoiler and attached it with velcro to the back side of the grill. It sits between 1/2" and 5/8" below the grill. That should help prevent air from getting under the body. I also drilled a second set of holes to move the body back 3/8" farther back. I'll try both methods and see which makes the biggest improvement.

Thanks again,


Chris

alex4r, if it is of any help, i wanted one of these bodies to try so i ordered it. Im in Utah and the price was.... interesting. but i wanted to try it so i did it anyways. i got a follow up email the day of shipping that stated i was being given a refund with the reason of the shipping system can sometimes over estimate shipping costs. i got quite near half the shipping cost back.

Thanks for the info!
Harold sent me a PM and hooked me up with a good deal on shipping for 2 bodies. Truly an awesome guy! :nod:

They are on the way, I can't wait to get them and start painting :D

I went and laid a straight edge across the fenders on my JC #205 Raptor - depending on where you measure it, there's about 1/4" drop down in the middle of the body compared to the edge of the fenders. The Method body is straight across, so if you leave the mounts in the same place, it's going to be lower. Closer inspection of my old JC body indicates the 2w rubbed enough to go clear through the paint in 3 of 4 fenders!

One notch up on the front body posts and it clears by enough, I think. I wish I'd known that before I trimmed it, else I'd of left another 1/4" of apron in the front. Next time.

Cameron Kellogg 03-23-2012 08:26 PM

I raised the front of mine up one hole too on my SC 4w.

:eek: Wow I bet that will look pretty cool all mounted up.

J_Bone 03-25-2012 09:03 PM

These look nice. I'm going to see if I can cancel my current I ordered 3 weeks ago at my LHS.
I wouldn't trying these if shipping isn't too much.

apriliamille 03-25-2012 10:18 PM

did you see my post a few above? im just a little north of you just in utah. wouldnt think shipping in the end would be that much
