Engine Choice

Cheers all, it's much appreciated!! Will look at all the suggested engines!

Is this your first taste of 8th Chris? Sure you'll enjoy it, I've been loving running the electric one!

[Chrislong]

Yeh mate, first timer - newby - etc etc. Looking forward to it.

[DaveG28]

Has anyone any experience with the P3XS?

Is there anywhere that does rebuild services by the way?

[Marvin]

I'm guessing that's a Picco? They usually go well, and are fast, but from previous experience (both mine and others), they don't tend to last that long, particularly in comparison to other top brands like RB.

[DaveG28]

It's a Novarossi, a shop I trust have suggested it, but it's not been mentioned here or elsewhere where I've asked!?

[MALLET]

It is the starting point in the Nova off road 21 range.

I still will recommend an OS, but that K9 is a good lump and you could get 2 for the price of an OS.

The P3XS is a bit soft in the peformace stakes. The P5XS is alot better and as fast as most of the newer engines. The new range of GO engines look good with their coated cranks etc and start at around £130 +. How much are you wanting to spend and are your a regular A finalist as it's then easier to recomend an engine.

[DaveG28]

Well I thunk around £170/£180 would be my upper limit right now, any more and the risk of me killing it's a bit high. With my electric 8th I've been A final at BCL/Nitrocross/NRS level if racing, I'd like a chance if keeping that up!

I'm also new to 1/8 nitro, still need experience with setting the needles and what clutch stuff to use. I already got the thing a year ago, but timewise I've only got to spend 4 days on it so far

When I 1st started I got a budget motor with it, a Picco P3 basic. Cheapest thing you can get, since I figured better to learn (and error) with this thing than a motor I actually care about. At the track I was triing some things since it didnt accelerate like it should (it would stop for a second but keep going afterwards). Some guy offered to help me and about 10 minutes later the motor was destroyed.

Still dunno if the motor sucked to much or that they guy offering to help was a bit to ambitious on the needles.

Anyway after that I got a 2nd hand RB WS7II, and I know 2nd hand nitro is a risk, but it was cheap and it still passed the drop test (holding the cranckshaft and letting the cilinder drop. It should stop under compression when it's still good or atleast hold a couple seconds on compression)

The thingy runs fine for now. But got a old model RB S7 as backup.

So what I've learned so far is, don't let anyone work on your engine unless you know who they are and that they know there stuff. Also many modelshops will have older models of competition engines that they will let you have at a good discount. If you're new at this it won't matter if you've got a '06 or '07 spec motor.

Regards a clutch set up I'd go:-

If its a tight twisty track you are going on, then I would suggest that you use 2 carbon and 1 ali clutch set up.
If its got a lot of long fast straights then I'd put an Ali clutch set up in,
but if its a mixture of the 2 then 2 ali and 1 carbon would be the best to go for.
If its a loose track then go all carbon.

This is the new Go engine for £140 http://www.lstshop.co.uk/catalog/product_info.php?products_id=2873&osCsid=bb8cb0525 c7d0f7ee95e1de0fddcbcc2
With the cash you have left over you could get a good pipe.

Ran the NN21R at NNRC today, ran it in - didn't need heat gun, on Byron 30%. I got through about a litre to a litre.5 of fuel, and on factory settings its actually very close, ive turned the high end needle to lean it out by 1/8th and if anything - it may not have needed it and I did it only as it felt wrong, completely wrong, that the engine was so damn easy to get going well!!! ha ha.

Loved running 8th, can't wait to race it as today was a bash day (ideal for engine running in). I actually feel this class isn't as complicated now as I thought it would be before I tried it, thoroughly enjoyed it.

[MALLET]

You cannot beat getting high on nitro

Glad you have got bitten by the nitro bug

Cheers Tim, looking forward to using it in anger next! If anyone is reading this and is tempted, but worried about complexities of running in, tuning, etc, don't be worried, its all quite straight forward to my relief!
