50cc gas engine

... Or, ... you could avoid all that headache in the above post, .. and just by a new DL-50 engine from HobbyCity for $325 + $38 shipping, and have a much superior engine for less money, and with a warranty.

I just fired up my DL-50 from DLUSA.com for the first time last night. Only took an hour or less to get started (including flooding recover) and is a BEAST! Realize that this is my first Gas Motor EVER! I think i went the right way on this. So I agree with all these "experts"

The man is asking about coverting an engine, not investing in Chinese clones that have already proven to be less than stellar. Still wondering where you get the "much superior" idea. Better buy some spare mufflers while you are at it, word is that they are prone to beakage.

I'm guessing that the "Hobby City" you are referring to is the one in the FAR EAST, and has everything modelled with Chinese girls???

Gotta love that FTL 45cc gasser for a mere $175. . got to be a real earth shaker for a price like that.

If you are gonna plug a 50. . may as well let people know about he XY-50 engine for a mere $210: http://www.hobbycity.com/hobbycity/s...idProduct=5789

It may not be "superior" but the price is certainly right.

Looks like he's asking the either modify OR buy question here. but that last sentence does suggest he's willing to work extra hard to have the bragging rights. SO maybe the question is actually retorical? IF so, we should go back to talking about HOW to modify his motor...yes?

Actually, the entire thing is pretty open ended. Most people have their own opinion of how things SHOULD be done. There are so many options in the 50cc market it's gotten quite silly lately. and the prices of some of these items are ridiculously lower than we are used to paying. Perhaps we have been overp[aying by a good margin for so long that we think we NEED to overpay in order to get good quality??

The reputation of the DA50 has carried it's clone (yes, it's a cheaply done cast-crankcase clone folks) the DL-50, and th copies of THAT motor, into the market as viable alternatives. Personally I'd never buy a single counterweight single, because in the larger sizes it's impossible to balance the engine very well, and you get harmonics and vibrations that are much more evident than from a dual-counterweight single. But, that's just my personal opinion. Others will disagree, and have paid for the single counterweight/cantilever designs hand over fist. to them I say . .Enjoy, you get what you paid for.

BTW. . I ordered one of the single ignitions, with pickup. At $38 total cost (including 3-day air) for a two cylinder unit, it's less than HALF what I'd pay from CH or any of the importers of the RCXcel rccdi ignitions, and probably comes from the same facility.

[Frankswd]

So where did you get the ignition? Is he going to be able to use it in his modification? If so, give up the link!

It's a wholesaler price to a business, and it's for a twin, not a single. You'd have to pay full price. but the hobbycity site has single cylinder ignitions for sale, at a slightly higher cost. They look like clones of the RCExcel ignitions, but it's hard to tell, and the quality may not be as good.

Try BRILLELLI 46GT $375 dollars price includes CH IGNITION & MUFFLER.You will have POWER to spare.00900021.jpg

mmmm. . power to spare compared to what?

NOT going to let this get into a bashing exercise. The Brillelli is listed at 6500 with a 22-8 prop, probably a Xoar since they also benchmark their 50 at 7000 (or 7150 depending on what part of their site you look at) and thei 60 at 7500 (or up to 1000 more than a 50, again depending on which part of the site you look at) all with a 22-8 prop, and the Xoar is mentioned for the 50.

6500 is not so good for a 22-8. My BME-44 hits that, and more, easily. I'd be putting a 21-8 on it (which is what I do on the 44) and letting it hit 7000 or more static on the ground. You gotta remember these are weedie/chainsaw conversions, and are ported for higher rpm numbers to make their power. The LEAST I'd want to see on the ground is 7000 rpm.

7000 on the ground, with a 22-23" prop, is fine, since the prop will not go transonic till about 8700 rpm or more. Max rpm I'd want, on the ground, would be about 7700-7800, and man it would be sounding WICKED!!!!!! To get that rpm from the Brillelli 46 would take a 20-8 prop, probably, maybe even smaller.

Remember, these are weedie/chainsaw conversions. .with piston ported intakes, 2 transfer ports, bathtub chambers, lower compression, and an exhaust that needs help. They need rpm to build higher cylinder pressures and make more power, and are designed for 7000-9000 rpm operation usually. Lugging them down to 6500 rpm is not where you are going to see the best power, throttle response, and longevity from the engine. They are meant to be cooled not only by the airflow over the cylinders, but by the amount of air/gas/oil going through their internals as well. More rpm=more cooling, and better engine life in this case.

EF Yak 54 /74" Brillelli 46 Running a 20-8 Prop.Its a beautiful thing.Hey did you get that picture of Voodoo2 from the ATL Hucktober Fest to him yet?

hey bomer dont pay any attention to the dl hater. add the componets up that you will need to convert the 49 that you have , and if its more than the DL, get the DL. you wont be sorry. just make shure you buy it from DLUSA. bob is a great guy to deal with. and the mufflers in question were fixed and have no problems. every motor company out there has had a problem or 2 at one time or the other. anyway the DL you ask about is a very good choice for the money. you cant go wrong.

A) It SHOULD be a great motor, it's based on copying the DA-50
B) Stating that "every company has had problems" may be true . . but cracking mufflers, or even having them fall apart, means that the original manufacturer missed some things. . on something as simple as a muffler??? What else is going to fail?
C) I hate no engine. . . I just despise the business practice of COPYING someone elses hard work, then selling it as your own stuff. . .very ignoble, and unscrupulous.
D) RCEast, out of Rocky Mount, NC, carries the DL-50 for LESS than DLUSA. You can get the DL50 for even cheaper than that by ordering it from China, directly to your front door (less than $300 total, including shipping, no business discount). WHY pay some importer markup pricing?
E) There are design shortcominngs, pretty substantial ones, when using a single-counterweight cantilever style crankshaft. Vibration is the main problem, because you are trying to counterbalance an on-center mass with an off-center rotating weight. Kind of like spinning up a paint shaker at certain resonant rpm's, and not my idea of how to do things properly.


BTW. . I'm sure the DA-50 could be sold for less than the DL-50. DA is in business to turn a profit. If you'd rather give that profit to the Chinese Communists, who are slowly destroying our economy anyway, please be my guest. The little guys making the engines don't make that much, who do you think reaps the most out of each engine sold to the USA?

As a caveat, there are some companies, such as RCCDI, whose product is not only cutting edge, but extremely affordable, and we all know where most of the ARF's come from. After what Thunder Tiger, ASP, and a few othjer Chinese "entrepreneurs" did to OS Max and it's engine line by copying it's designs, I really get heartburn over copycat engines in the Gas engine market.
