HSN Half a turn out from flush
LSN 2 and a half turns in from flush

If you want to make it run turbo plugs you need to just change the head button not the heat sink

You can get them here when they get more in stock

Ok, so those are the factory settings. So if I go a turn rich on the HSN and 1/2 a turn rich on the LSN, that'd be good for run in?

You beat me to the underhead, I just checked a-main and ta-da! http://www.amainhobbies.com/product_...oducts_id/4046

I had a look earlier but couldn't find it.

I'm going to go with the heat cycling method, similar to what someone mentioned on the first page of the thread.

This motor is great! I haven't got the 'K' version yet and was wondering if there was a big diffrence.

the K uses the P/S from the P5

That's it? Just those 2 extra port's?..Cool..I have a 7 port p/s that i had for my p-5 wonder if that will work in my plus?

the 21-5k uses an onroad style 7 port block that has seperate fuel diverters for vertical side ports and uses the standard p5 p/s with the r7 rod and has the drilled lightened head . the engine is a lil more efficient and even smoother than the 21-5 . one of the best engines of all time from nova is a plus 21-7t !!!! badass machine .
later, monty
oh and by the way all long stroke nova p/s sets will work in the plus series , 421b, 621b, 821b p/s sets are different though, longer stroke duration, smaller bore, 8 ports !!

I've put over 3 gallons (12 litres) through mine now and it still goes like a wild animal!
I found i had to run a hotter plug though after about 5-7 litres as it kept flaming out with a colder plug.
I put a C2TC in it and it is back to full noise and no problems.
I'm going to strip it down and check to see if it's ok inside.
I hope so.
