I have been running the P3 / P4 depending on temperatures with great results.

I liked the p4 over the p3 from os
but liking the orion #5 better
or #6 when is over 80 deg.
on different note anyone want to get in o ordering some ori82178 button and long bottom needle kits from out of country seems like the orion distrib. State side horizon cares not weather or not they get them in
Speed rc has them but are out of country

Im new to Orion motors, but not to Star motors, but i recently was given a Truhe edition engine, it needs to be rebuilt but i cannot find any information on information regaurding the piston and sleeve.
Any info would be awesome, just hope this engine is as good as my Nova BTT's have been.

Hey guys I'm new to nitro and picked up a mbx6t and it has a Orion crf .21 I beleive 7 port engine but has no pipe,so I need some recommendations.

Well the 7 port has a lot of top end so I would probably get the Orion 2013 pipe which will give you a nice bottom end but will tame your top end alittle. It will also give the engine a wicked sound.

Thanks

I need some help
I brought my RC here in Saudi
I've broken in my Cody King 21 CRF engine with 1 1/2 gallon sidewinder 20%
By mid range it keeps bogging down
Tried to lean it down on LSN it works fine on the bench but when i put in on track and rev it died again temp is 240 to 260 especially when i approach the jump halfway flying and come down engine died?
is the venturi will affect tuning too i used the standard 7 and used also 6.5 still the same effect, check the carb everything ok except the carb retainer o-ring is cut off, maybe this is the culprit, thus it affect the tuning too, i'm using nr5 the weather temp here is about 80 deg
please help!!!

Sounds like tune is way off also might have small air leak
take motor out remove back plate and carb clean both re in stall with motor seal i use lucky 7 but many high temp engine sealents work
after this i would start at one full turn in from flush on bottom and 1 1/2 in on top
tune bottom to lean bog and then richen two hours then just tune top to power or temp u want to run if bottom tune is not spot on will never run proper also change glow plug to new one

Man bad day yesterday first quali. Came off way to hot 300
Second quali. Motor came off 240 perfect
20 min. Main one stop at 10:20 all good lots of smoke
19:45 last lap last trip down 200 foot front straight
BAMM. ANOTHER DISCO. MOTOR DOWN BLOWN ROD

THAT IS 8 OF THEM I KNOW OF AT THIS TRACK ON THE SAME STRAIGHT SAME PROB. BLOWN ROD
oh well it had 8 good gallo.s on it before that so i can not complain will put another one in it and go again still needing the long bottom needle that no one seems to be able to get.
Also if any are looking have 2 gal old jtp with choice of pipe for 210 shipped

8 Discovery motors or 8 motors in general?

1 jtp
7 discos
All run by imtermed. And up drivers three by sponsored k driver
Mine was only one of all of them to get past three gallons
Funny as i am harder on motors then all of them

Sucks for orion as all of them but me will no longer run the motors due to so much rod trouble

You all must have one Hella long straight.. I know of 4 Motors in my little town that have out lived all of those, cept your 8 gallon one.. 2 of which are mine the other 2 belong to a Team Orion driver..

Straights 200 that last 30 ft is rough i guess

I have had people tell me the older WERKS engines had some rod troubles back in the day.. Might just be a growing pain combined with that monster straight away you alll have..
