Thought this was a thread about the Rex Paloma? I just wanna see some feedback from anyone who actually ran one and hear the differences between the limited and the regular blue head one.
All you guys have good points BTW.

What he said!

That is also explaining the bad idea to break in an engine in the winter and use it in the summer.


well your bringing in another factor here ... Engine being too cold !

So I do wide open breakins where I have the head wrapped with a competition heater... I have the mixture so rich fuel is often pumping out the front bearing, but because I have the heater on and active the engine stays hot even with a crazy rich tune... I have done this for hundreds of engine and never had any issues with front bearings blowing their seals, which is more or less what we are debating.. Some of these guys seem to think the extra oil and fuel somehow will cause mechanical damage to the bearing itself.

I am trying to help you understand that what you saying in GENERAL that running lsn overly rich in not going to kill the front bearing,This is not completely true.Some people do this,when they are ether breaking in the engine they run about 10 to 15 tanks and then you start to lean out,So that is why I asked you if you ran that thing rich the hold 4 gallons or You just never change a 8$ bearing.Is not that I trying to OUT you,Is just you are not trying to lisend at all what I am trying to tell you.You say,You say had One bad & good orion engine and that it,you discover some thing new.Think back of so many people that break in ther engines with factory setting (Two overly rich needles) and get 8 to 10 gallons on ther mills.Look man like I said,Do what ever works for you.

You sir do not know how to read (or type). I never said all orion (Orion) engine(engines) in vietnam dont (Vietnam don't) run right. I said all the WC limited edition engines that came to vietnam(Vietnam) didn't run right. I also clearly stated that I ran it overly rich because I heard it needed to smoke, no smoke was harmful to engines. So I made it smoke which made it overly rich. As a noob I had no idea that a bearing would go bad or that it would need replacing. I actually thought at first that 4 gallons was fine but maybe could be better, so I really tried to understand tuning and started asking for help tuning my engine from the better engine guys in Vietnam. This is when I started going to a real track more often. I still did the on road buggy thing as it was/is popular in Vietnam but again started getting help from other drivers on my tune. Then 7 gallons, a lot more then 4 gallons, then I found RC Tech and bought a second buggy so I got a WC Orion engine and bang there were all your questions about what I did or didn't do. You think that you know me, even after this you still don't know jack. So please quit trying to put words into my mouth

You starting to get mad bro? LOL! It's just a debate about if a overly rich lsn kills a front bearing and if it blow out is rubber seal. I din't say I know you,I just know what you type...I dont know how else to tell you do what ever you believe works. LOL!!!

I just saw this tggread abbd had to post my paloma ltd experience. The paloma limited edition was the first engine I had neal mod for me and it's been a monster,reliable,easy peasy tuning,and idles like an absolute dream.stock it was a ripper but modified is a whole nother level oinkif awsomeness!!tns mod paloma ltd is absolutely where it at.all i can say is try one. I just recently got it pinched and put tko ceramics and new rod in and I swear its even better than before.8mm restrictor,9886/41001,bones brew 30/8,c6 plug and never look back.9886/41001 basically works freakin awsome on every engine neal has done for me.

these were too pretty not to share.
built with the double sheild front bearing ceramic rear, with the full mod. if you want a paloma you want one like mine.
thanks Neal

This is a recent Paloma I did for another member. It was not 100% completed when pictures were taken. I also modified an Elite 5 for the same member. I will post pictures of the Elite 5 later (in the Elite 5 thread). The Paloma is a fantastic engine for the money.

I also attached two pictures of an XZB-II I did last summer. It was originally my personal engine (Sold it to a racer that lives in the New Jersey / Pennsylvania area). This engine was ridiculously fast and pulled forever. There is other work done to it (not pictured). Its hard for me to post pictures of completely modified engines (showing all work performed). Reason being is that people try to duplicate it on other engines and they end ruining them. Each engine is different and requires different modifications. Even having multiple of the same engine does not mean they will be exactly the same. Each and every engine is different due to mass production.

What kind of fuel milage are you guys getting out of your paloma Ltd with the #8 in and 9886,41001 combo it will be going in a 4.0 truggy and the 4.0 buggy as well.

HaulinBass 04-26-2016 10:16 AM

i dont have an 8 restictor my 7.5 is bored to 9, i do have another 7.5 as well as 7,6.5,6.0,5.6. i could do some testing when my mp9 gets here today, just add 30 seconds for that losi runtime magic lol

hobbstimothy 04-26-2016 04:38 PM

So i see were you guys are talking about power my question is are any of you guys getting ten main run times if so how and the other problem is if i barely touch the throttle my motor will idol high for a few seconds then drop. Why is this. I run the 6.5 restrictor power is fine and i got2 gallons on it with metal pinch still at the top

1. Make sure carb is closing to appropriate gap quickly (not closing slowly).
2. LSN (low speed needle) is a bit lean.

I have modified several of these and the racers that are running them (on race tune) with 9853 & 9901 pipes are getting 10.5-11min. I raced with a Paloma (modded) when it first came available. I paired it with a 9901/ 41020 and got 12min on race tune. Track was semi tight with high traction.

edit....even adding a 41001 to your 9901 will make a big difference...for some reason the 41021/9901 combo has terrible top end and just adding the 41001 will give the engine a huge boost

What about the 41005 or 41027 headers?

I'm shopping Rex USA right now and I see these headers have that same shape as the 41001 but different lengths of longer.

I'm wondering about experimenting with these other headers to keep the pipe out there where I don't have to cut a bigger notch for the exhaust in the body.
