This is only starting point.

The setting is pretty safe for Novarossi inline pipes. For other pipes, the HSN might just be too lean !

If these settings are to be used for breaking in, I would richen the needles more. Just my opinion.

If I need to tune the engine to race, what I do is best to set the LSN to 4 turns out and HSN to 6 turns out. I do this on most engines. Idle screw is set such that the slide carb is having about 1 mm hole opening when closed. You need to keep throttling to keep the engine running. Set the LSN to lean it till the engine idle RPM goes up a little and then back out a little till the idle remains constant. That should be the ball park LSN setting. Now tune the HSN till you get the engine revving to the highest RPM very easily. Then back out / richen the HSN a little. Test it on track to fine tune.

If the idle is dropping, lean the LSN a little bit more.

Thanks a lot for the tips.
Last weekend I got lots of problems with high idle rpm only for 10 sec after a zooom. Trying to solve them brought me lost: i first tried to rich the LSN without any noticeable advantage, then I tried everything with my poor experience.
I was running 16% with #5 and 0.3 shim, outside temp 12 C, JPL turbo inline pipe.
I will try your routine tomorrow, thanks again.

Now im using 16% Model technic fuel...just for play. but the problem is my engine seems to die easily. I know i have 2 tune differently becoz previously using 25%...but really headache. Can anyone suggest me on the HSN and LSN?
Like prev on 25%, HSN 6T LSN 3 1/2T using shark pipe #6, so now 16% HSN=?, LSN=?

In genelar, less nitro=less power.
Must compensating it with leaner HSN and or LSN.
Just watch the engine temp, most NS base wont go normal(ideal) at below 100 C (tropical country).
Dies easily.. could be too rich/cold or too lean/hot.
Change the plug accordingly...engine too hot, change to hotter plug/lower number and vice versa...
If still goes wrong... reduce the head shim and or reduce the pressure line length.
Hope this helps.

Finally raced the MX21-MF AAC last weekend. Probably put 4 liters of fuel into it. So far it is still in good shape. Oberservations so far are:

1. Once the engine is run-in, there are almost no nip in it at all. Still runs great.
2. The power band is push into the higher rev. You will need to gear low and slip the clutch a bit.

Will probably put another couple liters on it to see how long it will last. So far there are no signs of wear of liner and piston. The only alarming observation is that the outside of liner might wear out from vibrations rubing on the crank case.

I would think they are a sweeter engine than the ABC version.

Voodo_Magic... Use the Novarossi C7TGF Med Turbo plug... You're using only 16% nitro and the weather/temp in your area is warm to sometimes cold... The warm plug will work fine. If you step up to a higher nitro fuel, you should move up to a cold plug. Hope the info helps and good luck.

Hello all.....

I am running a NovaMax in my MTX3 at the Uk foam nationals, 1 of the tracks we race is VERY fast (12 second laps), over half of the track including a banked corner is full speed.

What kind of pipe setup would you recommend for this circuit?

The banked corner is very fast, lots of engines cannot handle the banked corner well and drop alot of RPM due to the load on the car.

Would adjusting the pipe length help keep the RPM stable under load?

thx......rich

Voodo_Magic... the C5 plug and C7 plugs are different... I would use and warm turbo plug if you can find one. Any major brand will do. If you're running anything below 30% nitro, then use a warm plug... You can use RB's, McCoy's, Top, Rossi, NovaRossi's and Sirio Turbo plugs... Just use the warm ones. I'm sure your lhs can point you in the right direction... Goodluck and happy racing.

UK_RAGE,

Hi mate,

How do the max peformances compared to the JP or the NSR5.
Reason for asking is that some thieving B*****D stolen my G4 E class with a Nova Rossi RR12L5, head unit, amps and subs from my car last week ! Going to place an order for the G4 E pro from border, hence looking for a new engine as well. Knew that Ben Kensall was running a Rody RB whom FTD as well. Was gonna for a JP FX 5 , but Nova Rossi are bringing out a 7 ports version next week. Is the max have a greater bottom or top end, and how do you rate it to the like of RB, JP or Sirio.

thanks
