1/8th Nitro - how much does engine size matter?

It really doesnt make much difference.
Technically the small engine may run a bit hotter with higher revs. But how you keep it tuned will have a bigger effect.
Are you sure you are ready for nitro? It is alot of pissing around and tuning involved. Get yourself an IR temp reader and really learn how to tune them. If you just sit twiddling the screws it will never run properly. They are NOT plug and play.
There is a lot to be said for the plug and play of electric.
I know petrolheads like to think nitro is more manly, but there is a reason most switch to electric in the end.

Just be prepared, it may be all tinker and less fun.

Its really is not that bad, get a starter box is my recommendation though. There is no dark art it's a simple little engine, just take your time on the run in.

I got mine out last week after nearly three years on the shelf and after a flush through with new fuel it started and ran just fine.

I used to be quite into nitro R/C cars but have since moved on. I had a variety of makes including Hpi, Team Losi, Kyosho and Schumacher.

Tuning the cars takes a bit of practice but is absolutely doable and very satisfying when you get it right. Just make sure you have a few spares (glow plugs, charged glow starter etc.), fresh fuel and tools with you.

It's the noise / smoke that I found the most challenging - you really need an empty field away from public areas to properly enjoy them or you just get complaints.

.21 was a fairly typical size for 1/8th Buggies with .28 more suited for the Monster Trucks but if it's just for playing around it's just down to personal preference.

In terms of manufacturer, my 1/8 Kyosho MP777 Buggy was by far the most reliable, durable car that I owned so would probably be my choice if I was looking again.

I do love a nitro buggy! The smell and sound is so much more awesome than electric even if the performance doesn’t have the same gap it used to.

I’ve raced 1/8 rallycross with an sworkz s350 evo/associated. Both used an RB Blast .21 engine. I also have an HPI Trophy for general hoonage. The Trophy is VERY strong. I used to take it to a bmx dirt track and regularly sent it 20 feet into the air and landing on its lid, I’ve never broken anything at all bar the spoiler came off once. So I can recommend those. Being an HPI product, spares backup will always be good too.

A starter box is a good investment as the pull cords can and will break. You could keep a spare as they’re not dear.

A lot of people say tuning is a nightmare etc etc but in reality, if you have a little patience and know-how it’s very simple. Rarely will the low speed needle need touching. high speed, work in quarter turns either way and you won’t go too far wrong. Better to be too rich than too lean obviously. There are plenty of videos on YouTube which are easy to follow. Get a spare glow battery too as it will go flat just as you want to use it. The same stands for glow plugs, get a couple of spares as they will burn out just when you don’t want them too.

Do bare in mind that they are really loud at full chat and some people find it annoying.

I’d personally go for something with a .21 simply because they tend to rev harder and more revs means more good. there will be very little, if any difference in power.

Have fun!

Lots of good solid advice here.

Yep starter box is the way to go, pull starts just get you fed up really quickly.

And yep tuning with a temp gauge will get you a better and more reliable method when out in all conditions too.

Now onto the choice of which one.

You have made a wise choice in looking for a manufacture that has lots of spares available.

As you know i have both a HoBao buggy and a Kyosho MP6 too.

Now I’m not really going to help here.

But if i was buying one for fun, it would be the HoBao VS 30.

Buts I then looked on my favourite store for spares and option parts, AsiaTees, but the option parts are limited.

So my choice from you list?

It’s got to be the Kyosho Inferno Neo 3.0

BAsed on the Inferno 7.5 there’s lots of parts you can get, and for me the big one is swing arms.

Here’s some of the parts they have, but not that many in stock at the moment.

Seems blue arms are in stock.

Sorry if I have given you more to think about.

Good Luck.

[nigelpugh7]

And if you can stretch the budget a bit i would be looking at this one.

Seems they are in stock at Wheespin and Modelsport too.

[nigelpugh7]

Lots of nice Inferno option parts in stock here.

Wow, just wait a sec, noticed its not actual stock at wheelspin.

It’s worth a call to them to check that, i have waited weeks for items from them shown as shadow stock, and that was pre lockdown too!!!

Nice I just wanted to make sure you wouldn’t be waiting ages for it to come.

Can’t wait to see some pictures, and a video too of the first start and drive.

Never had an issue with any carbs on my engines letting air in, there is a large rubber O ring where it mates to the crankcase, so it shouldn’t be an issue.

I’ve been gagging to get mine going to have a play, but there’s no where I can go with the IC cars at the moment.

So I’ve been having a play at getting the Dig servo set up working on my Losi Comp Crawler.

I’ve had that almost 9 years and never really got it working properly!

Something Else to play with.

I might just start up my OS40 lA engine just to enjoy the sounds and smell!

[The_Jackal]

Sealing the carb is a good idea.
Also, check EVERY nut and bolt and part. This will give you a good idea of how it goes together and make it more reliable.

Not familiar with the SS or VS, but have a Hyper7 and can vouch for them being bloody good cars. Well screwed together design, solid, fun, and seemly more durable than the 10th scales. I got the H7 Sport TQ .21 circa 2004ish and loved it, main reason for the .21 for me what I thought I might race it and some clubs where saying they limit to .21 but its certainly no slouch!

Never had a starter box, lowly student.... but did spend more time faffing with the recoil than most things!
With a bit of adjustment (I had a few 10th scales before hand) it runs fairly well first/second pull.

Only thing I really changed was the servos, nice mid-high power one on the steering, and a slightly faster one on the throltle/brakes helped a lot.
