Thank you for supporting, friends!

A lot of weird, impolite and non-respectful people in this world and we cannot prevent that since god create different people in order to make the world having more colors.

However, those unfriendly people would be left by major eventually.

I have modified engine for over 10 years……… for modified 300s engines is not a big deal (30 engines per year averagely). If I really rely on this for my living, I would disappear in the world many years ago. So you guys could save your time for other business attacking even my work is pretty outstanding.

Since I love engine modification, I even bought a website domain and develop my own stickers. Stickers are really not cheap, a letter size sticker sheet cost me US$20 and I have to order 20 at a time at least.

Those people thought I have stickers that meant I am in business and tried to destroy me, it is really ridiculous. Actually they knew nothing other than criticizing, tons of US folks have own website and stickers on their hobbies. If you have chance go to surfing, folks build own surfing board and put their stickers/decals (also website domain printed) on the board. They even have their own T-shirts and have decals on their cars. Other hobbies have same practice as well.

As a lot of rctech members PM me about helping them to modify their engines, since some engine may need a lot of job (especially on crankshaft), I declined their request because I really do not have time to do that. Sorry guys!

On the other hand, if I am an engine manufacturer, I would answer all kind of stupid questions. Since I do not represent any factory, it is not necessary to tell what I have done behind the pictures.

My engine modification is based on my testing and experience. Those who always talk about timing are really BS anyhow. This topic/problem has been resolved by the factories when they put the engines into the packaging. Even the timing could be changed; it’s only talking about 0.00XX inches cutting, that cutting I really don’t want to mention.

As I said, since mass production could not keep stable and consistent quality……… fine tuned modification may help to push the engine to expected limit. (A $100 engine really hard to beat a $400 engine honestly; however I still modify those cheap engines in order to grow my experience and knowledge….. recently my brother told me my modified Tamiya engines which mounted on an old TG10MK2 chassis could beat his friend’s NT-1 which equipped with Nova NS12 engine.) If people have chance to have one of my engine, then they should know what is the different when comparing with the original.

Polishing is necessary since those areas has been cut or modified. Polishing is the only method to cover those ugly cutting marks. And I like to polish as a mirror like, whether is necessary, it is up to you.

Since our country (USA) is the largest and major market in the world, that’s why all guys come up to here and express their thinking. It’s a good thing anyhow……… however they always forget to be polite and humble and doing in a wrong way when they are crazy and tried to complete others on business. They always like to criticize others without any solid support and I saw this happen again and again for many years. I would understand but I do not appreciate that.

You guys cannot destroy me anyhow, save your time; and I will keep posting my engine jobs here.
