Hello All

Champion RC is releasing a new engine to the market. The first in a series of engines is the Champion 5 port 21. This engine is based on the original GO 5 port engine which was one of their best sellers however it has some refinements that will improve its appeal , reliability and ease of use.

Firstly the carburettor is all new 2 needle. Carbon Alloy Composite body and smooth taper HSN and LSN giving smoother fuel metering.

New Steel Crank without Tini coating.

New Case design with extra cooling fins.

Heavy duty pro rod.

Lower CG drilled head design weighing 10 grams less that previous designs.

Notice the engine is all black carbon coated. This gives a more uniform heat exchange helping engine stability in race conditions.

Our aim here is to give support for the engine to its users. We do not sell directly to the public.

We are currently looking to expand our operation outside of Europe to the following countries.

USA, Canada, China, Russia, South Africa, Australia, New Zealand, Vietnam and Middle East.

All dealer enquiries can pm me for further details. You will need to provide us with your details and company name.

We have been making a series of training videos specifically for this engine range including Run in , Tuning and Maintenance. The will be freely avail to all customers and we will give support here to help get the most out of your Champion 21

We have some pictures below and will post more as we go along.

Thank you for your attention

Hello All ,

We have been looking for a decent tuning and run in procedure and of all the ones we have tried in testing we found this one suited the engines best. I was written by one of the developers for the Go factory.

We have adapted it slightly to suit.

If you have any questions please feel free to join in.

Champion RC run in and tuning method.


Check to see if the engine sits flush on the mounts. If it teeters or moves (like a bad table at a cafť ) then inspect why. DO NOT BOLT INTO AN UN EVEN MOUNTING AS THIS WILL STRECH THE CRANK CASE AND DAMAGE THE ENGINE.

The 7 Second Pinch Test written by Mark de Berard ©

Pre Run In Check

*Check your tank seal is air tight

*Glow Igniter Charged

*Starter Box Charged

*Radio Gear in good order

*Fresh Fuel Ready


Run In Procedure

Pre heat the head of the engine with heat gun or hair dryer for about 45 seconds.

Now start the engine and warm it up for about a minute. Then choke the fuel line, 1 cm from the nipple to see where the idle gap is set. Itís important to set the idle gap FIRST, so it revs up a little from idle and drops off till the engine stops. If it revs up a lot, lower the idle. If it doesnít rev up at all increase the idle. Please do this in small increments, ie. 1/8th turns only.

Now we do the LSN ( low speed needle ) Ideally the engine should rev up slightly from idle and die after 7 seconds. If the engine takes 14 seconds itís too rich, so lean the LSN a bit at a time till it reduces to a 7 second pinch. If it only takes say 4 seconds then itís too lean so richen the LSN a little. Repeat this till you get about 7 seconds on the pinch. NOTE please use needle nose pliers to pinch the fuel tube. This will ensure a proper pinch is applied to the fuel line.

This is a cold engine setting, ie. has not been run for more than 3 to 4 minutes. Once the engine gets hot the pinch time will reduce down to about 2-3 seconds which is optimal. Once this is set you then can tune the HSN. First thing is make sure you only have half a tank of fuel in the engine. This will give you an average tank pressure.

Ok , on the box give it a rev up and let it sit. Try it again, It ideally should rev out to almost full revs. It should rev up cleanly but be just slightly rich on top.


The engine now should rev out cleanly and when it hits max rpm should 4-stroke a tiny bit when on the box. But save revving it out till itís had some run time, ok. Now while on the box let it idle and listen to see if the engine is happy. That is, running ok.

If its making horrible noises or doing something unusual AT ANY STAGE, shut it off and inspect your set up. Most engine damage is done in the early days because we are so excited to get it running and miss some important steps in our set up, so be patient !

Now if all is good with your set up put the car on the ground and play with it immediately. The reason why we want you to run the engine on the ground is because this causes it to heat to its conditioned temp and expand the case and sleeve to its correct tolerance. When you run the engine under load it draws more fuel and lubrication.

DO NOT IDLE ENGINE ON THE BOX FOR TANKS ON END !!!! THIS WILL DAMAGE YOUR ENGINE !!! AND VOID ANY CHANCE OF WARRANTY.

Play with it on a high grip surface like grass or bitumen. Towards the end of the first tank bring in, choke fuel to stop the engine. Listen to the pinch .. it should be about 2 seconds now. If its not adjust it. If its say only 1 second , richen the LSN 1/8. If its 4 seconds then lean the LSN 1/8.

Do not stop the engine by either plugging the pipe or hitting the fly wheel. Hitting the fly wheel will eventually stretch the rod, plugging the pipe floods the engine and makes it hard to start.

Once itís in, check the head bolts to see if they are tight. Check mounting bolts as well. These can rattle loose in the first few runs. Check to see your filter is right, the plug should not be leaky.

Now each tank after this is like a qualifying period. You MUST be vigilant to see if the engine is happy. if its running well then each tank you may give it more throttle to the point when on your 5th tank you should be respectfully driving at close to race pace. Getting good tank time. Our engines love the 8 MM restrictor. It makes great power and economy. If you want even more economy set your EPA to 50% open. These engines make almost full power at half throttle. Best Shim and Plug choice is 0.4 mm with a medium heat plug typically number 6 Nova, P5 OS, 99 Odonell, LRP 6, and run on 25 % nitro.

Carb Angle Adjustment, If you need to adjust the carb angle , loosten the pinch bolt and move gently. If it dosent move do not force it. Take the pinch bolt all the way out both sides, this will release the grip the pinch bolt has on the carb. If you force it you may damage the carb.

Recommended Fuels

Byrons 25%

ODonnells 25%

Neo + 25%

If this engine performs like my old Silver Head GO 5 port, it should be a real performer, that engine was one of my absolute favourites, a real cracker for the money back then. Will be watching with interest.

It is good to have a starting direction for the most suitable run in method tested for that brand of engine. There's a few of us interested here in Australia to see how they perform.

Is this engine the similar to the older gx5r, like the one Mark from NAA uses for the Godzilla engine.? I have Marks Godzilla engine & its been pretty good & goes great, so if these Champion engines are based on the same GO gx5r but refined like Marks then they should be a good unit.

Hey Guys

Thank you for the feed back.

Yes to answer , the new Champion 21 is based on the original Go Gen 5 , 5 Port engine , the same one that Marc from NAA based his MG and Godzilla on. This original engine was used by Adam Alexander at Buggy Party 2009 in truggy to take the number 1 spot !

http://www.rcspecial.com/news/?p=38040

He says it was the best engine they made besides the MG of course lol

As with any nitro engine , the success of it running well depends on the driver and the educative tools avail to him. We hope to give a lot of feed back on how these things like to be tuned and maintained.

The changes were part of a list of things we saw people wanted changed , so we listened !

Obviously Go has taken a bit of a hit over the last 2 years. This is , in a weird way , a good thing. They are very motivated now to make the best engines they can and going by their history they made some excellent and highly competitive engines.

The Champion 21 is a well thought out package.

Here is a pic of the Champion Combo with pipe and clutch kit ... the price is really good !

This is a re named release of the Underdog Project motor we have been selling here for the last two years - designed by Robust Chen and associates during his year as designer at GO Engine Co.
Same motor (externally at least) , same packaging. One of the initial pictures in this thread shows the motor with its original Under Dog box. A grey box with the growling bull dog on it (the trade mark of the the UDP engine line).........

Some markets did not like the name Underdog, so Mr Chen released a second batch of motors about one year in, called the Champion, to be sold in these markets.
When Mr Chen left GO under a cloud, the UDP / Champion line was to the best of my knowledge discontinued in favour of the new GO GXII Plus - Go's new push into the market to get them back on their feet.
To say the Champion is an all new design with new features is not correct.
The motor is two years old, and has been sold here, and in some Asian markets for some time.
The UDP was a 4 Port design, so I guess a different sleeve has been fitted ?
We were one of only a few companies to market the Underdog, so to most people it appears new.
Looks like someone is dumping all their old stock ?
The only "new" motor being made by GO is the recently released GXII Plus.

The UDP was a great little motor - all I'm saying is its not new - it's a re badge.
We are, and have been the GO Engine Co agents in New Zealand for nearly 8 years.
If you wish to market GO Engine Co produced products here in NZ, you will need to do so through us.
Check this with Joana Ling (sales & marketing), or Simon Yii (Vice President of GO Engine Co).

Here is a link to the website of one of our customers that we supplied the Underdog Project version of the Underdog Project / Champion "Total Solution Kit" to.

http://rc.franktonmodels.co.nz/index...ducts_id=15579

Box and engine look very familiar - except for the Champion marked cooling head.
Note the date the webpage was updated with this product - Feb 2013. We received our first UDP order early / mid 2012 from memory.

Looking at the pictures you posted, it appears the engine is the old UDP crankcase (plus crank/rod) and cooling head, fitted with the new GXII Plus 2 needle carb, in combination with the new GXII Plus 2103 pipe, and it would seem, some of the old Pro Series Gen 5 or GX Series Gen 5.5 sleeve sets - an interesting arrangement of previous and current products from the warehouse.

I'm guessing it will be a pretty sharp performer - but it's not quite what you describe. A "new" engine, made around feedback from customers etc it is not. It can't be - the bulk of the engine was designed and first produced around 2 years ago.....

Have not received your PM as yet.

Here is a link to the "new" 2014 GO engine, currently being sold by GO Engine Co distributors around the globe.

http://www.go-racing.vpweb.co.nz/GO-GXII-Plus--21.html

This is the next generation follow on from the extremely popular GXII-5RHO.

Like myself, I don't think these distributors are too happy about a re-vamped 2 year old engine being touted as the latest design from GO Engine Co. And I also don't think they would be too happy with someone trying to push said engine into their already established (with GO Engine Co Taiwan) markets around the world.
My apologies for hi-jacking this thread somewhat, but I felt the need to protect my, and other fellow GO Engine distributors established businesses against this sort of product invasion.
