As I mentioned eariler, we are working on MAC.21 rods. For those who are in need, please give us a shout!

The price will be about the same or only a little more than what we were selling them for last year.

They will fit CMB Valvola too.

Good boating,

Andy

Great news just in time to going to need to rebuild my mac 21 in another month getting a little tired after 5 years of running. Hope to see john again at the races always nice to see him his wife and son happy boating Robert R&R Racing
 
Andy, Im so glad i didnt spend 400+ dollars for a cmb 21 motor!!!!!(I actually got a brand new mac 21 with pipe and header for 100$ less than the price of a cmb motor from a very nice gentleman from Hawaii!) bottom line is im sticken with mac motors and parts for as long as you guys are in business!! You,John, and the ladies are a great group of people that model boating desperetly needs and i hope you run the table in sales when all is said and done!! sincerely, Bill Gibson
 
Andy, I can't wait for the new pics on the web site. I was just there and couldn't find them. Any word when they will be up?

I too have standardized on MAC motors for my boat racing needs. Though I don't get to race as much as I would like to, I have been buying up MAC's whenever I can afford one. I have 14 or 15 of all engine sizes in my possession, from the 84 (4ea) to the 21OB (2ea) as well as many spare parts. And don't bother asking me to sell any of them. I think that Andy Brown has spec'd and developed one of the most powerful and reliable model marine engine designs ever produced. I can hardly wait for the new engines. CMDI has stood behind their products, even when the factory did not. John has personally helped me at a couple of races, even when the issue was some simple sorting out of a new setup. That in itself speaks volumes of CMDI's commitment to their customer base, and the hobby as a whole. I also have been bitten by the lack of spare parts, and CMDI has had one of my 45's for a warranty repair for quite a while; but I know the situation, and Andy and the girls have always been friendly and honest about the situation. I hope to get my repair back soon, but I know it will be worth the wait. I'm sure that CMDI will make it right, as they always have in my experience.

Go Andy! I hope to see you or John at some races next year.

We also have new Bullet nose Stainless Steel Drive dogs. They are .460" X 1/4" with two set screws. The .460" O.D. makes a pefect match to Octura hubs.

We are also making .430" X 1/4" to match the Propshop hubs.

Be sure to check with us for your flex shaft needs. We now have 1/4" square drive cable.

We've also added dual P/U rudder blades. 1.2"X6.0"

Jon, We should have the pics up on the web-site by tomorrow.

Good boating,

Andy
 
Pics of the Billet AB 67-80 pipes and the Billet AB 91 pipes are now posted at CMDRACING.COM.

Be sure to check back often. New items will be added regularly.
 
Thanks for the support everyone!


The 2007 NAMBA Nats has been totally dominated by MAC engines.

That is so amazing to me considering we have not had engines or much parts in two years.

Better stuff coming soon!

Good boating,

Andy
I know that the air cooled mac .21 I used got me to a win in A mod tunnel

Good job on the win Eric!

We are currently working on some improved MAC O.B. parts and will be assembling some new MAC OB engines soon.
 
Thats Great Andy, Can't wait for you to start on your 67 & 84 piston/sleeves.

Thats what I need to keep my good Mac's going.

I'm looking forward to the release of the P/S for the .45's and .67's. I have a .45 that is compeletely worn out, And a .67 that is still going strong but will need a P/S by next season.

Thanks for your efforts Andy!

Ron,

Pics of the rudders are now up.

We now have dual pick-up blades too.

Many of you have Speedmaster rudder systems on your hulls,

but would like to use our thinner, stronger straight blades.

Straight blades provied more consistant transom forces to help keep your prop hooked up.

Therefore we will soon be making our straight blades to fit the Speedmaster pivot block.

Example: Our dual pick-up blade is .195" thick compared to the Speedmaster blade @.250"

At the same time our blade is stiffer due to the high yeild strength of our alloy.

We are also thinking about making our pivot block to fit the Speedmaster transom extension, as our pivot block provides a more positive clamping force on the blade.

Good boating,

Andy

P.S. And yes, we will also be making our complete rudder system with different styles of brackets and extentions to suite all types of hulls. This will include mini sizes and large sizes too.

You answered my next qwuestion in the last paragraph! :)

I myself would be interested in a mini rudder to fit on the Speedmaster bracket and not drilled for a water pick-up for my air-cooled mono.
 
Hi Andy,

I received a nice order today.

Thank you!

lots of great new products from CMDi with more to come. Gotta love it.

And made in the good old USA too.

The bar stock pipes look great and gang,if you need any drive dogs,

Andy's are really nice and already have a radius on the leading edge.Good stuff!

Andy,

thanks for all of your hard work,patience and the huge investment to help our hobby grow.

We're all looking forward to bigger and better ideas along with your new products.

Also can't forget the rest of the CMDI group, a big THANKS to all! :)
