Precirotate D5 Engine
Does anybody run these Precirotate D5 engine's. I personally never herd of them. Any info much appreciated. How does it or does it even compare to the Rossi +4 Werks B5 and B6, Ed Mods JS TX521
I seen this deal for $219 Eninge 0801 Pipe and Header Exhaust Gas Cooler Tool/Engine Bag Plug http://www.pr-rc.com/program/product...3265102457.jpg http://www.pr-rc.com/program/product...9930381950.jpg http://www.pr-rc.com/program/product...5215161239.jpg http://www.pr-rc.com/program/product...9106215209.jpg[/QUOTE |
a guy i know just tried one out and they seem really good. smooth power plant and tuned easy and will idle forever.
|
I want to buy one so bad, but I am afraid it is too good to be true. That is a lot of extras for $219. I'm about to pull the paypal trigger.
|
Like the fact that it comes with an exhaust cooler, but not digging the little purse.

nice!!!!
This motor looks awesome for the price.Engine,pipe,Carrying bag(mans handbag)LOL,and an exhuast cooler,This might be worth a try.
|
Arent they the same as the Alpha and New Go motors?
|
It's just another engine from the GO family, should be a good motor. We ran Novarossi carbs on this family of engine with good results. That was the only week spot on the NEW GO family of engines. IMO

Just got my D5 kit a couple of days ago from Nathan and everything looks great. Gonna start break in this weekend and will post my findings...the motor is not modded but I think its like a base 5 port GO/Alpha.
|
This is a Stock Engine
:nod:Guys,
This is the first stock engine from Precirotate. Yes the price is very good when if you look around the 0801 pipes alone from other companies are like 79.99 from other companies. The engine is great just remeber it is a go based engine and will tune like one. |
Just wanted to give some feedback on the D5, I started the breakin today. The first tank I just idled very rich just to clean out anything that was in the motor from manufacturer and it purred flawless. Then began the varies tanks of fuel slowly getting to that full throttle position and no problem not even one flameout. At the 7-8 tank the motor became very smooth and started showing off its powerband (hard to believe its not modded), I believe is better then my Alpha green head. I'm very impressed with this combo the temps never exceeded 240 and down here its very humid and hot (98). Looking forward to racing this motor next weekend and so far this combo is definitely a great bang for the buck.

What fuel and plugs are you using? |

I finally got the D5 engines, D5 Kit Specials, and Exhaust Coolers on the website.. I'm such a slacker. Enjoy! Nate.

Ok this weekend I got to run the D5 combo kit in its first race with a semi race tune and the motor was flawless. The track was large with lots of big jumps and loooong straights and the D5 made small of everything thrown its way. The weather was hot (99 and humid) the motor came in after every 5 min qual at 240 with a 1/4 10 1/3 fuel left. The A main was 15 minutes so obviously I came in for one pit at 7 1/2 and finished 2nd overall with a temp of 265 and motor was still idling flawless and showing no signs of power loss or tuning issue. It was my first showing with my Agama so I was learning the car and testing a motor at the same time. Alot of people kept asking man what kind of motor was it and everytime the response was (preciro what?), hopefully in time the name but the performance is awesome. i will definitely be adding a few more to my collection after furthor test of longwear, but as for now get one, you won't regret it.:nod:

Great to hear. We have had nothing but praise for this engine. That is a great finish. Hope it brings you to many more. I have sent you a PM. |

Your motor did look very good out there Saturday. Everybody was struggling to get decent runtimes on the large track. I know myself and most of the field had to come in twice during the main. I think I might have to consider one of these for my next mill. |
how do you guys think this motor would run with a 2013 hooked up 2 it?

To tell you the truth I have not tested it. But it runs well on the PR21C so I would imagin it will do the same with this engine. But we have seen the best runtime/power ratio with the 0801 Pipes. Jason |
Anymore feedback on these mills? How's the power delivery with the combo pipe (FEMCA 0801 set)
I'm hearing they're GO based, which is good cuz I really like my GoTech. However, I'm wondering about origins of the company, whether or not they're gonna stick around, and parts availability. |

These are Go based. I've been looking into the Go's quite a bit lately. I know the US distributors are selling Go's with the short needle conversion already but I think these still come with the long. If you do some research you'll find that in many country's people prefer the long for better run time and more throttle "feel". When I was asking about the Go's one of the NZ sellers gave me an awesome tuning guide helping with the differences in short vs long needle. It was such a good explanation I asked him to post it on the tuning bible and he did. It's by grizz and is on the last or next to last page of the bible. He also has alot of info under tech tips at his site that are very easy to understand.

Yeah, if you're not a great tuner it's best to get a short needle carb.
The long needle requires perfect balance between gap, lsn and hsn. It's also pretty sensitive to plugs, proper shimming, fuel, and outside temps and humidity. Even with the short needle the Go engines tune from the gap and LSN first instead of a more traditional hsn method (like OS). In general, if your engine is performance ported and transfers efficiently it'll be more finicky than a standard engine. Just get a short needle and be patient with these go-based engines. They're totally worth it! |

I'm running this exact motor in both my buggy and truggy without any problems. I originally got it for my buggy to try out and found the quality and power to be second to none. I just finished break in on the second motor for my truggy and the damn thing is awesome. I would not mess with the motor pipe combo it is perfect, my buggy has over 4 gallons, ridiculous compression, still original R3 plug and delivers consistant 8-10 minutes. I'm not the best engine tuner but these motors hold a tune better then my previous P5XL. Guys don't hesitate to add this line to your collection, I sold my Alpha greeen and orange head BNIB cause I was so impressed with this product.

PR21C
2 Attachment(s)
I have the 21C version, and this is just a heads up or FYI of what can happen, my motor has 1/2 gallon on it, and makes great power, and great run time. Last weekend, I noticed some fuel seepage behind the flywheel, no problem I'll put a TKO in. Upon pulling the head off, this is what the piston looked like, and after further tear down the whole piston is like this, crank, sleve and rod show no markings or pitting. I contacted Acend/PR-RC, and went back and forth, I'm concerned about the realiablility now, they indicated that I may have left the motor out in the open and that could have caused it, no, not true. There latest responce is " they see no problem
running in this situation". To say the least I'm not happy with it, the motor still has good compression and pinch, does run for how long who knows. I thought atleast they'd send a repalcement piston and sleeve. What do you think? |
should have went with a GO GX!

High silicon content aluminum looks like that although yours does look a little different. They could have used a cheaper aluminum like Os does and you would need to have it pinched more often. ( I pinch motors) Just put it together and run it, if there was something wrong with the pston it would have lost pinch by now. Or you could listen to Deadmancourt, can you tell he sells Go motors?

anyways MR ALPHA!...:lol:...dont be mad cause people are selling there ALPHAS to buy these GO based engines!:nod:....

I am happy with the motors performance, but highly concerned with the pistion, I've had 3 OS motors, several Nova's and Werks ,and never saw this before, so I'm not sure what to make out of it, manufacter doesn't seemed to be concerned, so buyers beware.

yeah, if you go to amain you can see all the go based engines pics of the p/s/r and all the pistons have it, its the new harder aluminum. looks like the reedy and some of the new rb's have it too... buyer beware, lets be fair.
|
Well all this talk got me curious so I took my D5 apart and everything looked fine. Besides the carbon build up everything looked great it this mill has over 3 gallons, I'm not gonna worry unless motor has problems.

Also you should read or know more before you comment. We also offer an optional needle set if you would like it to tune more like a Nova style motor and again it is not 70.00 but 13.99 Here is the link for that if you need it. http://www.amainhobbies.com/product_...dle-Tuning-Set Thanks for you comments |
