Testing Carbon Parts, LCG Shorty & New Mid-Profile Servo - B7 Series - Part 4

Today we start by fixing our bent aluminum chassis, then we test the carbon suspension arms and side rails, a lightweight LCG shorty vs normal shorty, and install a brand new prototype servo, the ProTek 815, the newest mid-profile servo to fill the gap between a low-profile and full size servo case.

Great series. I’m glad you recognize some placebo effects and are real about it. Most of us mortals can’t tell a difference in a lot of these mods but the battery and servo are two I think a lot of us could, very helpful.

[@3Dsinyourender]

Man I wish you all had this layout for regionals. That big jump on drivers right was killer but still fun!

[@88davidw]

Really love this series. I have a B7 so it’s very interesting to see how you guys get on with the changes. Brett is awesome as always 👍🏼

[@a1racer441]

It’s crazy how fast those front tires wear out. Nice series overall I liked seeing the upgrades and what worked and what seemed like it was placebo.

[@Chris_Love]

loving this series! Im running B7 this season and had my first track outing last weekend and just love the car, now it´s a matter of getting to know the car more and get faster

[@voodooreptiles3553]

Thanks for the great videos. Im making a b7d over the holidays so ill be referring back.

[@peterkarv2845]

You do such a great job explaining in and outs..👌.been watching the last 5yrs or so.

[@qtmblur6193]

im loving the videos so far, cant wait for part 5

[@MatMabee]

Good driving cool track

[@SeanLewisMedia]

Awesome video guys!

[@odiewan67]

FWIW, in the vehicle dynamics part of my mechanical engineering education they do talk about the advantages of bigger unsprung weight vs sprung weight...

[@BenHalverson]

1474g is the min weight for stock racing. Looks like you would need some additional weights in that buggy if you use the LCG battery 3:57.

[@Miguel.herrera.71]

Great video 💯

[@trevorfurlotte]

Also, pick a color yellow (not yellow) or white (always white) you cannot mix the two, or a kitten fails to get adopted at the local animal shelter.

[@TastierBackInThe80s]

It's a freaking rocket ship.

[@TroyAndersonrc]

Great video 👍 I wish we had large hobby shops in Australia like A Main hobbies. It's hard to get stuff for nitro like actual nitro, parts, hop up parts, nitro engines, fuel etc. we tend to have to resort to places like eBay etc. the internet destroyed our local hobby shops 4:29

[@gavinvucina]

You should give the promotion vipers a try. They have a harder and softer compound too so you can get some more life out of them if you need with the harder compound.

[@enzoquilici2994]

Hey enzo here Just got the new futaba 4pm plus

[@robotboot]

did you race though underweight with the LCG or put in a battery weight?

[@93jdmmike]

Love the video buddy

[@LyroLife]

Only upgrades noticeable to average humans are mainly tires tires and tires. Other than that, shock positioning, ride height and body/wing make noticeable differences.

[@danielmiecz909]

Buy all the r1 upgrades

[@virtualreality4me544]

Lol, I have every single R1 upgrade except the rear hub weight. They were out of stock at the time of my last purchase

[@StevenRasmussen-p2o]

Please do this series, but Stadium Truck

[@V8chump]

Please do a similar series with the new GROMs. A similar sized dirt track would be incredible with the Mojave or typhon grom

[@voodooreptiles3553]

Grom doesn't need a series. It's prebuilt and made for fun not racing. You can cover the info In about ten minutes.

[@trevorfurlotte]

I'm confident that a lot of B7 owners would be very surprised to find their chassis has the same bend if they took a close look regardless of whether or not they've had a major crash or not.

[@trevorfurlotte]

@voodooreptiles3553 nope they wouldn't be surprised?

[@Ultegra10SPD]

Are there any stock parts left on the car? What a joke. -U10

[@rccars4all]

whats the name of the guy doing the videos was he a pro racer b4 he looks like someone but cannot put finger on it

[@UnrivaledPiercer]

"Saving pennies that adds up to some real money in the end." I agree with the statement, but we all know in RC it works the opposite. It's more like "Spending pennies that adds up to some real money in the end." Next thing you know, you've got an expensive tuned rig and an empty wallet. Oops. I don't even want to know how much I've spent on my B6.4 over the years, more than I care to admit that's for sure.

[@adrastos123]

Thats overkill 4 an 8scale servo lol

[@paulfreimanis2202]

Seems like you've nailed the weight loss (in your wallet!). How much have you spent on this B7...??!!

[@Dav5049915]

A lot of tracks use the ROAR weight limit of 1474. Also, the LCG pack will have lower resistance, so that's why you probably saw the peak at 120A.
