Boy, Bernie is quick

2-56x1 1/4 tank screws would be good, there longer than stock, so you get more threads in the crankcase, they would be cut to length, what would also be good is to supply the 2-56 tap with them

The problem we have been having is that even our 1" screws are bottoming out and often have to be cut (especially on older crankcases), so adding more length may not add anything good to the equation.

well i was saying that the tap would be to add more threads in the crankcase, i know just putting longer screws through it wouldnt help.

Yes, got it

However, these are specialty tools that would target only a very limited # of buyers. Taps and dies are quite a specialized niche market and we only have very limited funds each month for new products, that's the main problem. Therefore, it becomes tempting to target only items which are expected to sell briskly.

What Bernie has been saying is really quite understandable to anyone familar with the purpose of a successful business.

What not to understand? (If a product doesn't "move" in the market what the purpose of offering it?)  

SD

We are always grateful for suggestions from our customers and have added many products to our offerings simply because someone suggested the product and we felt it would sell.

However, we cannot act on every suggestion as, sometimes, suggestions are made based on the immediate need of someone for a hard-to-find part. That creates the illusion that the part must be popular; hence why not stock it.

The reality is often that there may be a dozen or so buyers looking for the same hard-to-find product but that's it. We, on the other hand, need to manufacture parts in the hundreds, if not thousands, to obtain viable pricing.

In the first year or two of operations we had parts made that "everyone" wanted and felt there was a big market for. For some of those items we have a supply that will exceed our life expectancy.

We are just a 2-person operation and have to be careful in what product we invest. Having big capital tied up in slow-selling products creates cash-flow problems.

Thanks, Bernie, we're just glad you are there for us.

DU-BRO Cat No 360 is a tap and drill set for 2-56 ...mine cost $7.50

buy two and make one a "bottoming tap" with your griinder

yep, thats what i was just gonna do

Hi Bernie,

I am "new" here at the forum. I just posted a self-designed .049 sport muffler. Check it out when you can. Cheap to make... and certainly useful.

That's pretty neat Roger and thanks for posting that. Certainly something to try out. We did have 1,000 mufflers made a few months ago and they are selling briskly.

We have a quarterly e-mag and, if you like, you can submit a detailed story on how to make your muffler and we would be most happy to publish it in our September edition. Here is a link to our last edition:

How about diesel fuel?

Shipping fuel from here costs upwards of $60 per bottle (hazardous material) so definitely not an option.

However, diesel fuel can be obtained from Davis Diesel in the USA with reasonable shipping cost.

Yes, please do, a writeup would be great. You can say you've been Internationally published too. 
It's been tough to get regular submissions..

What is the cell type and count of this battery?

I am working on a glider and it calls for a 4 cell 1/3AAA battery. (Otherwise I need a UBEC and lipo which is more volume and lighter so it may prove a balance/fit issue.)

4 cells, each 1.2v for a total of 4.8v. Total output 220 mAh. They are designed to power a receiver.

Hey there Bernie, This nudge by "Rusty" reminded me of our communique'; on Aug.22. If your Sept. issue has not "gone to print" yet; I could get something together within 24 hrs. (Ea. coast) I seemed to have issues "conveying" the build; to some of the members. Where "some" don't comment at all... I can only assume that most; found my design hard to "visualize".

I "did" edit my orig. post; https://www.coxengineforum.com/t5505-a-cheap-sport-muffler

This would be a 1st for me. I read your entire "prev." emag issue... (it was a highlight of my day) The "proverbs" between pages are a HOOT! It's great to be connected to "Cox" people.

Incidentally; there was a post in "off topic" yesterday on "starting diesel engines"

https://www.coxengineforum.com/t5547-starting-diesel-engines

The gentleman "ebeneezer" lives in England. He'd acquired (estate?) a lot of diesels, and wanted advice. I assume that; being a forum member... he may have some Cox engines. I believe someone had a "killer crank" avail. for the .049... Does Cox Int'l. stock this part... or the "top end?? I am going to mention it to him; as I did your "Davis Diesel" recommendation for fuel. (Davis will provide ebeneezer with a "blend/component formula"; as they do not ship o/s USA)

regards,
Roger

Roger,

The last edition did not publish due to lack of contributions. The next edition is slated to be published at the end of September so, yes, please contribute to support@coxengines.ca

We do have the Killer Bee / Diesel crank available here:

and the top end here:

Bernie,

I have a lot of interesting things to write however, I am a horrible writer. Is there a writing guideline you use for submissions?

Ouch. I wish I had something interesting enough to put into a column, but I don't...

Hi Bernie,

 I build balsa plane recently, and my friend gave me some Litespan covering material. Almost ruin my plane. Its too hard to use. Local hobby shop not selling any light weight film.

I have good experience in iron-on material but most of them are just too heavy for 1/2A.

Just wish that Cox International will carry some stock like Aerospan, Ultracote Lite etc, since we are building just small 1/2A planes, maybe you can try to cut the whole roll into 2 for shorter roll or fold it smaller sheet so that can be ship it worldwide  

I think tissue and dope are good item too.

regards,
Ew

What ever happened to sending a couple free stickers with every order?
