Redcat Ascent Fusion Upgrade you didn’t know about! And Things to know!

[@PopShot76]

I always thought bump steer was when the front suspension is compressed, it causes the steering to move left or right

[@chainsaw7887]

Yes you are right. this happens when the panhard and drag link angles don't match

[@2fmrc]

I’m not sure what it’s called but I’ve always considered it when the truck would rock back and forth when turning period lol

[@AnySumptionBanter]

@@2fmrc thats more just a twist as you're changing the weight distribution through the chassis. a better chassis wouldn't do that and better link and geometry would not do that... ascent is not known for having good weight balance and geometry. imagine a hard body, you're on at a gate with one wheel under weight, you turn the wheel and hard body tilts and down you go. test it on your 24s as well, see which ones do it and check the links and see if you find a pattern; this is an interesting topic would love to hear more

[@chrispearce9224]

LoL. Yea bump steer is an affect which happens during compression of the shocks when going over 'bumps'. So the front axle must travel up and down to experience bump steer.

[@TheAmerican1963]

Great video !!!! Thank you !!!! I just bought mine on 11/25 and there are a few changes. The front u-joints no longer have set screws. They are the "non-rebuildable" type. The front pinion is now fully thread locked and you are right, the mount is "beefed" up for steering. I love this car as I am a noob and I learn from folks like you everyday. Thank you for what you do !!!!!! 🙂 edit: What dual stage foams would you recommend for Ruptures ? My car weighs 6.9 lbs. . I am using the single stage foam that came with the tires (they seem to work ok) because the large soft silicons seem too undersized. (green, Blue is same diameter) .... again, thank you !!!!

[@thomasmontgomery4382]

That is not checking bump steer, it is just setting end points.Bump steer is change of steering angle when axle goes through full stroke and articulation.It will bump steer and your end points will change and introduce servo overload unless you set end points at this point and accept reduced steering angle at some point in the flex.

[@2fmrc]

Yeah that’s what others have said. I’ve always called that bump steer and what you guys are talking about track shift (front shifts to one side when compressed) I’m definitely wrong on my terminology though lol

[@NFGRC]

Man I can’t wait to get my hands on one!!! Thing looks epic!!!

[@AnySumptionBanter]

on the bump steer can you also test the following: turn off rig, turn wheels to furthermost end, and compress and let it decompress then turn wheels fully the other way and do it again does the wheels wobble or toe in/out when you press down on the front as you compress and letting it decompress?

Ic3 fits ec3 but not xt60. At least mine don’t lol. Maybe you can cram them together but I’ve never really tried. I honestly don’t use spektrum smart crap so never really use that battery 😆

Yep. It fits like it was made to. I use my spektrum smart crap batteries in everything from my 8s Outcast exb, SCX6, to Gorgon and TRX6. What do I know though, I have always thought bump steer was the tires turning, or steering, when the suspension cycles through its travel. Boy do I feel silly!

Hey great video and thanks for all of the help lately. This my first 1/10th scale and I noticed you linked a Spektrum battery that is rated at 30c. Is 30c adequate for this setup or would >50C be recommended? Thanks again!

[@CraigAHaskell]

I was really looking forward to an upgrade build. Some portals, HW fusion, lcg fiberglass chassis etc. I'm struggling to see how I can build anything as good as this seems without spending more than it costs.

[@dezfan]

Looks like a little weight in the rear, and you’d nail it regularly! 😎

[@Justin_Newman]

Bump steer is caused by axle movement up and down causing the wheels to turn at full drop or full bump. If the chassis is moving when steering that means the servo is maxing out on the steering and causing the chassis to twist. Turn down the end points and fix it for sure.

[@Casitascrawlers]

I use almost all Gens Ace batteries I’ve had nothing but good luck & also the Amazon Zee batteries have been good as well.

[@whatfreedom7]

They are suppose to have a 60/40 weight distribution. So it looks like downhill isn’t its thing but uphill is great.

[@167switchback]

Have you ever try the dsm link rizer ???

[@2fmrc]

I’m running the one from 1tenth Rc on my other ascent. It works well. Don’t know that I notice any difference really but it fit well.

[@167switchback]

[@trialnterror]

Did you lengthen the rear axle location on the fusion? I have seen a couple peps do that and have good success.

Imo it’s the best rtr you can get for performance atm. Does it have flaws? Sure. They all do. Mostly just loctite the pins in the front axle and the screw that goes into the pinion gear in the axle. Besides those couple screws backing out I really haven’t had any issues! I really appreciate the sub!

[@Senditjp247]

I find these so helpful man 2 questions man im new to the rc world Awesome content man im loving it 🤙🏼 I just bought the new ascent fusion gonna get injora turbine 1.9 beadlock wheels they are -10 offset and gonna keep the awesome stock tires that come on the ascent u reccomend the blue silicone inserts from injora or red im in south Florida its hot year round jajaja And u think i will have any issues running that particular wheel, tire combination Does the -10 offset affect the performance much besides pushing the wheel outward ?? Because i know stock offset i believe is 0 on the stock beadlock wheels that come on the ascent fusion ?? And i actually went with the 1500 lipo 3s u recommended the zee brand Now im debating what charger -Spektrum S155 G2 1x55W AC Smart Charger, SPMXC2050 Or -OVONIC Mate1 Lipo Battery Charger 1s-6s 100W 10A Your opinion would be great man Now i know with the spectrum one i have to buy xt adapters With the ovonic would ibhave to do that as well Since im new i just want to plug in charge and “crawl” a buddy reccomended the spectrum because he said it literally plug n play no messing around with currents and stuff ?? Your opinion super appreciated man

[@Senditjp247]

Excuse me I meant to say blue or green inserts not red

[@2fmrc]

If you go spektrum with spektrum batteries you don’t have to worry about the amps you charge etc. It’s pretty simple to keep track of though. If it’s a 1500mah pack I usually charge at 1.5amps, 2000mah pack charge at 2amps etc. You can go as low as you want it’ll just take longer to charge and you can actually go really high on amps to charge faster but it’s harder on your batteries over time etc. I think those wheels and tires will work fine. I haven’t been a huge fan of the silicone inserts on 1.9s to be honest. A good dual stage foam like proline or crawler innovations work better for me but the silicones are cheap and will work. The stock tires are pretty good but you can definitely get better once you’re ready to upgrade those as well. Jconcepts has some really good tires. Megalithic,ruptures etc. proline bfgoodrich Krawler ta are good also. The wheel offset will just widen the truck which may cut down on your turning a bit but should make it a bit more stable on side hill. Should work I would think.

[@2fmrc]

You can also cram the xt60 connector into the spektrum ic3. I didn’t realize you could make them fit myself but someone else mentioned they used the two together all the time. You can also use a spektrum charger with any battery if you get the correct adapters etc. I have an S2100 smart charger I use and I never really use spektrum batteries besides that one 3s I showed and a couple 2s for the losi promoto.

[@Bonitacreekrc2]

front end geometry is poorly designed and dosn't allow for a normal amount of droop, the panhard holds the axle too far away from the chassis

[@thindigital]

@@Bonitacreekrc2 is that why the shocks aren't mounted in the top most holes (to get lowest cog). The front shocks tower position options look weird as many of them look forward of the axle. It is good to see them trying but there's still a lack of refinement to the design that they need to work on imho
