Will the p/s/c 21-2205 (old race) interchage with 21-2205X (gxr series)?

Got to run a Cera that I added some timing on it and had RW lighten and fill the crankshaft. I don't know about the stock one but the Modified one flat out RIPS. Easy to break in, super easy to tune, Idled all day with no flame outs. Ran a P3 plug with Ofna 086 pipe in a RB One R buggy. Bottom to mid was powerful but very drivable and pulled very strong on top. Averaged around 8:30 min on a full tank with the included 9mm restrictor. Im sure mileage will only get better as it fully seats in. Plan on testing this out with a OS 2090, 2060 and the Arrow 2103 pipe but it was perfect for me in buggy with the 086. Will also try a 7mm and 8mm restrictor. This engine is SWEET not only because of the price but performance wise too. Easily one of my favorite engines in buggy now. Since its based on the Arrow/vzb short strokes, Reminded me of the days I used to run VZB speeds but with more power. Get yours from RW Mods while its still available and have Rex do some mild mods to it. You will not regret it. Next up will be a Argus D52

Hello People , its Mark de Berard here , i have been wheeled out of the cupboard to get on line to set some things straight , say gidday to some friends and poke around and see whats shaking.


Just a brief history so everyone is on the same page I was the founder and owner of MassiveMods International, I was appointed as associate development manager for GO Engine in 2006 by the Go Factory and Director Vincent Wong along side Simon Yii and Lion ( original partner of GO Engine now head of Alpha engine TW )

In 2010 i was diagnosed with Lung and Bowel Cancer so that was my excuse for the fast departure and sale of MassiveMods , This was due to the high amount of carcinogens i was breathing in every day developing fuels and servicing at MassiveMods which saw me tuning up to 30 cars a day.

Pleased to say im not dead yet ( much to some peoples disappointment lol )

Since then i have been offered a wide variety of development opportunities which i have gladly taken on and while im really busy i still communicate with Go and Simon as they have asked me to come back and help re structure some of their product line. Simon is really been handed a lot of messy problems and is working very hard to get it back to how he had it before this problem happened.
I am doing what i can to help with that and maybe even developing again ... but thats another story.

Grizz was right , i dont do much with my new site as im flat out with development and government contracts now which take up a lot of my time however my heart is still in micro motors and i want to get some things ironed out as it seems some info thats being presented is not entirely accurate.

As far as MG66 and Godzilla they are very much alive and well. We have a lot of stock and parts a plenty so its business as usual.

The MG is now in its 3rd year as Tether Car National Champion Motor driven by Scott Clysdale results here http://www.trcaa.org/results.htm and Wayne Burns as well as a lot of other guys getting onto the MG , whats this got to do with Buggy ? not much , but its pulling speeds that are i.4 km off world record held by Gultiero Picco , ( please corrct me if im wrong ) so its fast i guess and we all like to go fast : 0)

( yes it says Go but they are all mostly stock MG 21 s for 3,5 cc M Class )

Grizz's old team driver took out NZ Nats with the MG and Ong Cheeong took out the Malaysian National Titles as well with the MG, ( forget which year i think 2010 and 2011 ) The Godzilla is just a bit more aggressive for off roaders in truggy and buggy class.

the above video shows a 28 Godzilla in a buggy at 1 min 30 sec. ( no this is not trick photography its pulling wheelies in a buggy )

So that i hope gets people up to speed as to who i am and whats happening with this range of engines. Yes RC Crew and Model Motorsports do have stock and will continue to keep all parts etc and as you know have great service.

Now on to the Champion Engine. Its a GO 5 port ( the Gen 5.5 version ) with a new 2 needle carb , new sleeve design ( keeping old timing pretty much ) and without the tini coating on the crank which nobody liked ( i guess someones listening ) And a new lower CG head 9 fin drilled ( someone is definitely listening )

Its tight ( bummer ) , just like the old gen 5.5 but its had the bugs ironed out with some basic changes ( listed above ) and cosmetic changes to look a bit cooler ( i never liked the top hat orange head ... ) while its a bit of a bitch to run in for some it holds comp for at least 30 litres because of the old pston and sleeve fit.

Anyway as far as i can tell its not being dumped , its being sold at an aggressive price to clear for next years model , which im gonna tinker with : 0)

So its a great spare , the Gen 5.5 was an awesome motor in its day , the only problem it had was the carb seals ( now German nitrile instead of what looked like red crayon coloured rubber that some of the carbs copped )


So thats it from the horses mouth as it were , if you guys have any questions ill be on and off for a few weeks as im over see new transitions for Go distribution and support Simon as he has always been great support to me and everyone in the sport. I owe him a big one for helping me when i wanted to develop the MG series of engines with Go.


Anyway hope all is well and you all loving RC as usual !

Cheers,

PS as usual forgot to thank RC Tech for being an awesome web site for all things RC , they really are awesome !

Cheers Guys !

Cool!.. Some new(old..) life in nitro.. Not just all Team Edition RTTE spec 12 $400+ engines (with a new matching pipe every six months..) for the über serious and über deep of pocket...

Thank you for the introduction, Mark. I joined the forum recently and always wondered who that MassiveMods. Glad to here you licked the cancer thing. Nasty stuff.

I am not sure what you are referring to when you mention the Champion engine. A Champion engine appeared briefly on my price list in 2013 and then dropped off. Is that the engine you are referring to? And what is a gen 5.5 engine? First time I've heard that term.

The 5.5 was the gx series, which came in 3, 5, and 7 port configurations and was paired with the 2072 pipe. A few are still being used today, especially in my area. Not the best of fuel milage but certainly enough power for any condition.

Yes.

What is the difference in powerband n is it rev higher?

I am told there is a difference but I don't know what it is or how much. I'll take a guess that the 21-2205X will give you more top end since that is what we see with the GXII-Plus compared to prior versions.

I believe the part number 21-2205X, piston/sleeve/rod set, was used in the GXII-RHO series whilst the part number of the GXII plus set is 21-2205X2

Yes, you are right about the part number. Thank you for the correction.

will crankshaft 14mm part number 21-0907T interchange with 21-0907T1 (silicone ramp)?

Good to see things are still going ok with the engines & yourself Mark, I couldn't seem to find any info about what was happening & had no reply to email either when chasing another Godzilla, a couple of others I asked couldn't tell me much either so it was looking like you had dissapeared.

CCZJORDAN, if you want an older style GO Engine (that really GOes) then check out Marks Godzilla & MG66 engines on the NAA website. (think they are GX5R but not quite sure)
Here's a link to the Godzilla engine.

Yes , pretty much all Go 21 cranks are interchangable through the 21 range.

EG a gen 5 and above C 2008 - 2010 Crank will fit a GXHO and vice versa.

New Poly Ramped Crank will retro fit older versiobns of GO 21 engines.

The HO series played with the exghaust port shape and went to a different sleeve lip and case lip amongst other things, a lot of the HO stuff was after i left around the time it came out with the 3 needle carb.

Thank you for the well wishes. :)

You should speak to Simon about the Champion, im sure he can help you with more detail.

The Gen Rating system is something I introduced just after i started with Go , it was meant to be a reference tool for me so i could differenciate between the revisions of engines sometimes within the same model.

It started at Gen 3 in 2006 in Jakarta Worlds with Ian Haley , we used the opportunity to modify a set of engines of which i supplied Ian with 3 hand built. He tested various mdels from Go and was going well but had a shocking time with tyrs and wheels that series.

The Go gen 3.5 was my first revision and that was the engien Ian used in that series,. it was reliable but back then the carb was not the best. We changed the carb in 2007 and it became the Gen 4 Silver head 5 port ( my fave ) ..

Thats when Go took a turn around and started to move up in sales internationally.

When the GFC hit in 2008 GO took off ! they were great engines at really good prices comparitively.

The Gen revisions went on to gen 4.5 , 5 and 5.5 just before the HO which is Gen 6

thats when i left for greener pastures.
