The 1/10 offroad RC thread

[S1MMA]

So I've had a love affair with 1/10 offroad since about 1994, always had a Losi kicking about in some form or other.

Had a break for about 5 years, but I'm now back with this:





The spec: Losi 22 2.0 mid motor setup, Absima CTS10 ESC, Speed passion 6.5 turn brushless, Turnigy 4850mah 2s saddles, brushless digital servo, Spektrum DX4S tx with SRS4210 DSMR AVC ABS rx. Running 18t pinion to get used to the power, it's rapid. Schumacher yellow minipins rear, yellow cut stagger on thin wheels front for carpet/wood surface.

Ran it last week at maritime, going to take a while to tame this beast! Running tomorrow at maritime again.

I also have a new Losi XXX CR, and a vintage original Losi XX CR Kinwald Edition which I am going to rebuild in the next few months. I have been hoarding new parts for it, everything is going to be graphite/titanium/anodised aluminium. Pics to follow.

So what have you got, what are you running/racing? Pics mandatory!

So - how're you getting on with the AVC (Active Vehicle Control)? It's fantastically clever, but in my particular deployment, it didn't like the very undulating ground, & at very high speed. Very eerie also to see 'something other than you' control the vehicle (inc throttle, if so set up).

I have only briefly played with AVC, it's banned on track so I've not seen the benefit with lap times. On a lower grip surface, it definitely worked - as does the ABS. I need more time to see if I like it or not, cars these days are so fast some tech to help out for those with less skill is always good as long as you can switch it off!

Nice bit of kit there chap. I've never done off road but always fancied a go.

Your going to a club with a very good rep you should get a lot of help from lads that race there.

[theboyfold]

Arif, as per your request in the other thread, here is my HPI!






I think it's pretty much the same as yours, there are a few differences but I think most are cosmetic.

[C.A.R.]

Excellent, love all things RC...

I dabble but not in any form of competition. Current stable includes -

Tamiya CC01 with custom body, paint, decals etc. an ongoing obsession I have with all things Jurassic Park-



Tamiya FAV, custom light install, some little scale parts added, upgraded motor but kept the gearing low as this is such a detailed model I didn't want it to go too fast!


My 1/16 Turnigy Buggy which comes ARTR for £45. Unbelievable value complete with brushless setup. Sadly spends a lot of its' time being repaired!


A one-off which started life as a Tamiya Blackfoot Xtreme 2WD monster truck. This is my plaything and what comes out most often for a blast around the park. Brushless + LiPo = lots of barrel rolls and laughs...

Snap - of sorts.

I bought one for my Son who is five. I know I know I should have started him on something more user friendly but I didn't want to end up with three or four cars. Anyway he drives it and breaks it and I so the spannering - so much more pleasant than working on the real thing.

His / ours has the the following mods - Asiatees has cost me a fortune

• Ally a-arms - the circlip mounts for the plastic ones kept popping off and getting lost so I gave up and upgraded.
• RPM wheels and Proline tyres - more truggy sized now and much kinder to driveline as they're massively lighter.
• Upgraded wheel bearings as the OE metal sealed stuff was poor.
• CVDs front and rear - big benefit in reliability over the dogbone design.
• Ally steering linkage and a massively upgraded servo - always seemed to get deflected over the bumps and it doesn't.
• Uprights and hub carrier at both ends
• New dampers - ally ones with adjustable platforms. Really not worth the money TBH and the only mod I've been disapointed with.
• Ferrari FXX 1/10th scale body modified to accept the wheel movement. My son picked this after he broke the truck body. It looks like a Ferrari Dakar special:

And it came with an upgraded ESC as I understand the OE one is marginal running 3S. This will do so all day without issue.

The only issue is a clicking front diff under load, but I've stripped it twice and can't see what is wrong. I have some new gears which I need to fit to see if it cures it.

No pictures as I'm at work.

Thanks, yes the guys at Maritime are all very helpful, they were giving me tyres and setting the car up when I got there, nice bunch and helped loads!

The idea of being able to mod these little things is quite appealing! I'd love to see the photos once you get a moment

Rhinochopig buddy - the half-shaft upgrades to CVD - this still seems to leave the receptacles at the diff side as normal cups?

To make the bearings last longer clean and lube them especially as its a off road car. Makes a difference how fast the car is and how long the run time is.

CVD is a good upgrade dog bones are rubbish. Keep a eye on the grub screws and pins they tend to want to come loose on HB/HPI stuff. Loctite the screws in.

The alloy dampers is a real good upgrade. Get them set up correctly will make the car handle a lot better. Get them all the same lengh to start with.
Fill with oil level with the top ( not sure what weight for off road ) move the piston up and down and let them rest to get all the bubbles out of them ( takes a while )
Build them up
Check the rebound, push the piston all the way the piston should come out at the same speed and the same distance. Its a bit trial and error but if you get them the same the car will work a lot better.
Then once on set the ride height.

I used to have an bosscat. Properly engineered

Good thread hi-jack Theboyfold!! My fifth-scale has been er - re-engined - and so I needed something in my life simple and easy to play with - it's been effing fantastic! It's also my first ever foray into electric. I'd be interested in the pics of the insides/suspension of yours - wondering if the MT is actually any different apart from wheels and body! It's overall fantastically solid and well-made - great attention to detail at every corner - so, amazing bang-for-buck (Wheelspin Models).





There next two are my solutions to the parasitic drain that the switch that comes with it has on the battery (so, a dedicated switch which completely disconnects the battery); and also for the need to be able to programme it readily - hence the permanently-affixed programming module! I also found it easy to flip and cartwheel without meaning to - and so wished to be able to play with settings such as drag braking force, braking force, and actually sometimes overall forward force. Acceleration I have set at Level 1 the whole time. For me, the Transmitter and receiver upgrade was key - as there are further settings which are important for me at speed - e.g. Steering Expo. I'm running it with 3S Lipo (deliberately, for run-times). I have actually also upgraded the steering servo (to a Savox), as the original was indeed a bit weak - now it will turn strongly from lock-to-lock on carpet, even with a bit of weight on the nose. Either way - more responsive in the field.
Your motor & fan look decidedly different, though - lovely fins on the MT, for a start!



And so this is all the access I need until I need to actually change the battery (so very rarely) - just windshield access to turn it on, and charge it when needed! The body stays on the entire time. Very easy now to just pick up and play/charge!


The HPI Mini Recon I got for my seven year old girl - who loves it, and is amazing with it (a year ago she was rubbish at it, & I thought that they must just be a boy's brain thing). The Recon is solid and well-executed.

[C.A.R.]

My boss bought a Mini Recon - fantastically quick straight out of the box.

Sadly the shock absorbers seem a bit weak. One shaft has bent and a couple of the shocks have 'popped' spilling their oil everywhere.

I did some research and bought some 3Racing RC18T shocks for him (which he still hasn't paid me for thinking about it!)

Dogbones at the diff end but I've never had one break yet. They get less driveline shock at that end though.

Buy them from Asiatees.com as they're a fraction of the OE HPI prices in the UK - a full set will cost you less delivered than a pair in the UK.

Fecking hell!!!

I've ramped mine down to 25% forward force, and it's still pretty crazy and speedy!

Saying that - my 7-year old I could probably trust with the Bullet ST now, as the Mini Recon is very pacey and really teaches her delicate trigger-craft!

Nope!! Your ESC seems to be the 'Pro' version!! And your motor has lovely fins on it. What country are you in?

I went for the ST primarily because of the tyres it came with - as I liked the look and behaviour on grass with those. My other car is a fifth-scale Maverick Blackout V2 - but it doesn't have a normal engine anymore!! The ST looked much like the Maverick - which I liked.

I'm in the UK, bought it in a store in Berkshire, Apex Models.

This has just happened to mine, which I understand is a common fault. This means I have to replace it, right? Yes? Then, if I am replacing that, I'll need to do other bits? Right? Yes? Good....
