Dont know, the idle was stable with the 6 plug, when it was just idling. But stalled when I let off the throttle sometimes entering a corner. Unfortunately there was too many cars on the track for me to hear if it stopped from lack of fuel or bogged down, but it felt more like just a flameout.
Think Im gonna need to buy me a few 5 plugs cause I dont have any at all. I used the P3 at all times on my OS engines. Suppose I can put a P3 in this aswell cause I know that works.

richen low speed 2 hrs , turn idle up a little , leave top until get it on the track then run it until fully warmed up , come in , check idle , if engine has a slightly rich idle up then comes down to nice steady idle , your good to tune the top , lean on hsn until you like the high speed , then fine tune lsn and idle adjust

has the btt already have a factory silicone filled crank?

Just changed the front bearing today.When i took it out it feel a bit gritty so yeah it does suck dirt like u said.Other than that its all good.
Just a few more question for u if u dont mind..Why do u recommend .65/.7mm head shim on p5xlt?Less shim is for more torque and more shim is for more top is that right?Im running stock at the moment but it has so much torque already.Not sure if i need anymore than that.But i do need more top if i can coz the track im racing have two very long straight.Should i add more shims to achieve that?
Also do u know is the losi RE12 is similar to novarossi pipe?Its recommended for nova engines and the shape look a like too.Thanks

Does anyone know off hand if a connecting rod from a nova 28-7t fit in the plus4? Part numbers are different but that does not necessarily mean anything of course.

here is a video for you Nova fans !!!

Thats ridiculous!

IIIIIINNNNNSAAAAAAANE!!!

Does anyone have crank for a FMS thats in good working condition with little to zero slop for salel? Also will a Torenero crank work on a FMS? PM me please with what ya got. Thanks!

Im also looking for a crank for a p5 too thats in good condition for sale. PM if you do please. Thanks..

I think I know somebody

Can someone else chime me on this please..cheers

shimming has more to do with a "sweet spot" in the combustion , relating to the volume of the combustion chamber in the head button , distance from piston to glow plug (ignition source as well as the nitro) , exhaust port timimg and intake timing as well as the relation the intake/exhaust have to each other which creates the "blowdown timing" number . so ya see its not really "just" the heighth of the shimming as well as many parts of the equation , i refer to the shimming heighth in a general term because i hate getting really technical and sh!t just too much work i know what makes these engines tick and how to get what i want out if them in terms of performance


so if you are going to use 25% fuel i would recommend shimming .60-.70mm in that range , yo can even drop down to .55mm but will require some expert tuning and stuff

Does anyone know if the older GO crank will work on the older P5? I was told alot of the parts are compatable with these 2 engines. If someone would chime in I'd sure appreciate it.

I recently bought 21-4c team and need pipe for that , will dynamite 053 a proper choice, I'm a little short on budget for 9901/21. And which plug for high humidity and around 90 degree ambiance temp. Any help will be much appreciated.
