Anybody ever make a ball bearing 1/2A engine? Maybe CS has one? Any others? Smallest I have seen in regular production is about a 12 to 15 size.

MP JET .061.. Diesel and glow. But sadly not in production.

Mr Cox

It a shame that MP jet are no longer made. The muffler makes it a bit heavy but otherwise it is very well thought through, proper glow head, ballbearing, twin needle carb etc. I also like the fact that they are classic iron/steel for the piston/liner, maybe I'm oldfashion but the ABC ones don't last very long in comparison...

There is also PAW, they are all single ballbearing in the small sizes, 1, 0.8 and 0.55cc.

Schlosser diesels in .25, .5 and 1 cc......+-.015, .030 and .061"

PAW diesels. 55, 049 and 06 come in single ball-bearing form, while the 09 comes in single and dual ball-bearing type.

Toad

Profi, Cyclon, Fora..... these are glow versions, currently available..kinda.

Meh, ball bearings are overrated. At least in larger engines they are.

They might make the engine turn over easier at low idle. Modified AMEs [plain bearing] keep up pretty good with the European ball bearing racing engines. For the typical sport 1/2A application, the weight of those bearings are just going along for the ride.

In addition to all that has been mentioned above, CS has the GZ 049 and 061 which are ball bearing. Picco has the Picco-Z or P-Zero which is ball bearing and there are a couple other 1/2a car engines that are ball bearing. But all of these are typically high rpm engines for smaller diameter props.

On my bench and in my planes I have a single ball race PAW .03, a single ball race PAW .049 long stroke, and a twin ball race PAW .049 and .061, I also have a TBR PAW .09, but that's an A class engine. And they are diesels.

The biggest benefits I find with a ball raced engine are in ease of flip starting and great low idle and throttle response for RC. The plain bearing PAWs I have are great CL engines and start easily with a few flips when properly and well broken it.

The .03 really benefits from the single ball race for RC use since I get a very low idle and will turn an 8x4, but is happiest with a 7x3. The "vintage" .049 is great with the single ball race: it is very smooth with a 9x3 at very low rpms (more quiet than an electric!) but likes an 8x4 for sportier flying. The TBR .049 and .061 are crazy mad on a 6x4 and fly like an A glow with a 7x6. They'll both fly sport and scale planes with an 8x4 great thrust and throttle response. The .09 TBR is the best engine I've got and will turn a 9x3 in a scale cabin monoplane with ease and great throttle response. It is a demon with an 8x4. Less prop than that and its out of my league.

Randy Linsalato (MECOA) manufactures the Fuji .05 dual ball bearing ABC engine. It is a bit pricey (cheaper without the muffler), but it is a real little gem. I have not had a chance to run one yet, but am looking forward to picking up a pair soon.

I had the opportunity to visit the MECOA plant two weeks ago and was very impressed with the variety of products that Randy and his crew have under production. Randy picked up a lot of the original Cox tooling and molds recently, and I saw bins and bins of Cox glow heads moving through the production process. If all goes well, I think we can look forward to keeping our smaller Cox and Norvel engines running for a long while. MECOA/K&B Manufacturing is an American company, located in southern California, and in my opinion deserves all of the support we can offer.

It might take 2 of those turkeys to get a plane off the ground. A few have already been bought and run by guys who post here with nothing good to say other than how pretty they are.
In "fishing lingo" I think it's called "presentation".

PsychTeacher

Ouch!

I think this is a classic case of not flying what you sell. This engine is obviously made for entry level cars that don't have a real high torque demand, like an engine that has to directly drive a usable prop. They unscrupulously have decided to use it as bait on the unsuspecting aero-modeling market, they know exactly what they're doing, BTW. For those who choose to support this company, please realise who and what you are supporting. There are other examples of guys getting totally burned by substandard MECOA offerings that are too numerous to list here.

Mecoa has had their issues in days gone by...no more difficult than any other company trying their hand at the hobby product game. Recently, they are making a huge effort to get quality products produced for the hobbiest. I commend them for it, the money invested and the fact that they are not overseas.
I will support their effort by purchasing items from them, As with anything, KNOW what you are buying and by all means, give them feedback on your experience and the quality of the product you buy. Just so "no" to negative attitudes, Support America.
Criticizm, done in a positive way, Does a lot to improve product lines. I see no need or reason to dis this company.
Support them.

Well, let's see you do a build thread and in flight video of a Toki .05 based project.....just for starters.

Toad

Don't like the Toki?? well, "for starters"' dont buy it.
There is a Grocery store near me, sells a good beer, along with others not so good and some that just should be banned. I dont boycott the store because they sell beer I hate.. Get real.
LOL thnx for helping me make my point. As far as ball bearinged 1/2a engines, there are choices out there... Most have been mentioned.
1/2a lives on!

So you're endorsing the Toki .05.
If not, either put up or shut up. If you want to send Psychteacher the message that the Toki .05 is a great engine and he should feel great about spending a day's pay on a couple of them, we've already put you on record as saying so.

Toad

LOL
I dont like the Toki, never said I did, but I dont dis the company that stocks them either, because they also sell other products that I can use.
You are such an ass Pig.. that is already on my records... LOL

Toad, anyone who reads the last few posts and decides who is telling the truth and who is just doing "damage control" will be able to come to their own conclusions.

Toad

Well, the way I see it, you are entitled to your opinion about Mecoa, I am entitled to mine,
Why you get upset to the point that you cant seem to let others state their opinion without a pile of negative, condensending responses back at them is beyond me.
I have no ties to Mecoa, so there is no agenda for me to enter into a "damage control" mindset concerning them.
I do like some of the products they sell and the fact that they are making an effort.
I will stand on that.
You already stated that you do not like them.. ok, That does not mean I have to follow suit.
relax man.

Toad

I'm good with it.

Psychteacher, ever since I got into the hobby, MECOA has been known [at least around here] as a "clearing house" for merchandise that the reputable vendors and suppliers wont touch with a 10 foot pole. We have a few very reputable 1/2A equipment suppliers here [at this forum] who I know care enough about their friendships and reputations to not sell junk that doesn't work, just so that they can make a fast buck on the unsuspecting purchaser.
I think we have a reasonable expectation that what is being sold has a 99% chance of working.......not the other way around.

Twanger

I like Mecoa. No one else I know of is doing what they do as far as bringing deceased products back from the grave. I haven't purchased any of their 1/2A engines, but I never have had an issue with their service or any of the items I have purchased from them.
