The "shine cuts" are for air filter clearance... and the lower ones are for easy access to the motor mount bolts (as I'm sure you already knew.. lol) Just felt like putting it out there... Thanks for sharing! ...almost bought a .24 version of this motor to replace my Savage 25's spent motor, but decided against it due to the bump start deal... keeping my eyes out for a deal on a "Big Red". I think one of those would be great for that truck (It's just for "play"... I don't race it or anything)

Hello from NY Todd! Really really enjoy all your videos! I recently acquired two mega zx21 nitro engines. I think they may have association with picco. My question please is do you know anything about these nitro engines. I don't know whether I should keep them or sell them. Thanks you!!
@NitroTalkwithTodd 5 күн бұрын
They are picco based engines, made in partnership with Serpent. They were never super popular, so replacement parts are going to be very hard to come by. Other piccos of this era had rod issues, although I've never heard that specially about these. I world say they are great collector's items, and if you decide to run them they do cook. I would say they should only go up in value, especially if new.

There's two different OS .21 rods, they have the same bore on the bushings but one is 0.5mm longer than the other. The long rod is used in the VZ-B, XZ-B Spec 1, XR-B, and lots of onroad engines The short rod is used in the XZ-B Spec 2/3, B2101-B2105 They sometimes are mixed a bit weird in OS based engines. For example Spower S7 (evo 1 and 2) use the XZ-B Spec 2 piston and liner while using the Spec 1 case and long rod. The Bullitt B218 use the XZ-B Spec 1 liner but short rod.

@NitroTalkwithTodd 12 күн бұрын
I'm not positive, but I think OPS manufactured their engines themselves in Italy. They were pretty popular in the 80s-90s, also made glow plugs. I have heard great things about them, and while it has great top end I was never able to be totally satisfied with the bottom end. After swapping carbs, adjusting head clearance, clutch tuning, etc. I got it darn close. Certainly good enough to race. But it just never felt the way I like.

Great video and topic !!!! So I always look for the air to flow through the “cooling head” mainly because I’ve been taught this in books I’ve read and videos from very reputable people. That being said “I” don’t believe or have I ever heard anyone in books or videos say it was to cool the “glow plug”. However the “heat sink” and or “cooling head” is to remove heat from the whole engine. The air flow through the air passage on the “cooling head” will greatly assist in that process. I DO NOT believe the logos on the head have any value as to what way the head is mounted they are purely decorative and the manufacturer may put them in different spots. The cuts outs however for the exhaust and mounting bolts are a CLEAR DEFINITIVE FACT on how the head should be mounted. STILL there are examples you have shown that this is not always the case. Some engines don’t even have air passages like you have shown here. I’m thinking maybe those are RTR engines and manufacturers think a basher is not gonna run for an hour straight. My guess would be that high end race engines built to run 45 minute to an hour long main will always have the air flow passages and they WILL flow through the head when mounted properly.

I haven't done a full count in years, but I have a very good Idea. I'm positive there are larger collections, but I don't know who has them. The highest count I've seen here on KZbin is I believe just shy of 120. I'm a fair bit past that. And with some creative counting(a crankcase, cooling head, head button, backplate, p/s/r set, crank and carb equals an engine) I could add 30 or so more. I believe I have the largest cooling head collection, glow plug collection, and a great deal of pipes. I don't want to toot my own horn, but I have been collecting for many years now, and I am very proud of what I have accumulated. I have thought about doing a full engine count video, I may someday. Thanks for your comments, I really enjoy sharing my collection with others who share my passion for the nitro engine.

I agree, adjustment of the mid needle should probably be avoided. This engine specifically is prone to air leaks at the mid needle, so I do recommend maintenance.

1st. Os , 2nd GO , 3rd Rb all are beautiful engines! Rossi are from early to mid 2000,s, RB closed down of their own choosing and not aware they ever used force. Great collection for sure surprised you don’t own a JP Racing (JP Black) the first company to ever offer DLC coating in a .21 buggy engine. Jp started in 98/99 made the RX 21 Team 8 port and Pro ‘99 9 port comparable but better than RB’s C4/C5. Insane power. Later came CLB, SBK, Pro 01, P5 and a few others. Stopped his brand in 08/09 Wish JP was still Producing engines. I enjoy your videos…. Appreciate another collector.

Todd, I watched these 2 videos a couple of times because I liked them so much. I had a couple questions that I hope I didn't miss the answers to in your videos. 1.) Do you use the same procedure on "premium"/tight engines as you do on more budget friendly or RTR engines? 2.) On small displacement engines (like .12) would you cut the fuel in half? I realize these questions may sound totally dumb here... that's why I have waited so long to ask.
@NitroTalkwithTodd 22 күн бұрын
I do the same procedure on every engine that I break in. Most of my old race Novarossi engines were broken in this way. Yes, I would use about half the amount of fuel on a .12 It would take around the same amount of time, and it would be about the same number of(smaller) tanks.

@NitroTalkwithTodd Awesome! Thank you so much! I really appreciate your work. It really is a gold mine of information, especially when you consider how we learned in the RC world before. It was word of mouth or a magazine, back in the old days! Even 10 years ago, there was not quality, REAL, fact based information around nitro/glow land vehicles. There was bad advice/information present on KZbin and a million opinions online. Information on fuel would be a perfect example here. Or even something simple like front bearings! Or a bearing in a certain engine... like the MGT 8.0. It had an odd size... I remember watching a dang DVD for engine tuning and had all my notes out so I didn't burn up my gently used (but new to me) MGT 8.0!!! I was a nervous wreck! Haha! Anyway... thank you, Todd :) I hope you're doin' alright, man! :)
@NitroTalkwithTodd 14 күн бұрын
If I remember correctly, the 8.0 was prone to air leaks at the front bearing causing tuning issues right? I was just thinking about it, maybe it just sucked too much? Maybe there is a point when an engine gets too big, and can no longer be properly sealed with a standard front bearing. They are essentially air pumps, one could assume the larger the engine the more negative pressure created in the crankcase. Maybe bearings started leaking after minimal wear due to the excessive pressure... Interesting to think about, and experiments could be done, if they haven't been done already. I've been thinking about making a Nitro iceberg list. With obscure brands and concepts such as Singh grooves at the bottom. I appreciate the support, thanks for watching.

On a big block engine where base needle settings are unavailable, I would try 2-3 turns out on top, and 3-4 out on bottom. Most engines can start in that neighborhood. Another thing you can do is swap the carb out with a carb that is already set to good running settings. Thanks for watching.
