AeroTech Information Release

AeroTech Announces New Products at NARAM-48

AeroTech introduced a number of new products during the "Manufacturer's Forum" held on Tuesday, August 1st at NARAM-48 in Phoenix, Arizona.

After a recap of new products and sales programs that were released earlier in 2006, AeroTech President Gary Rosenfield stated that production quantities of the new 29mm G77R Redline™ single-use motor previously announced in May (P/N 77704, 77707 and 77710) were delivered to dealers at NARAM-48 and had already been flown a number of times. On Sunday, Bob Sanford demonstrated the G77R in his AeroTech "Arreaux™" rocket for a perfect flight.

The final design of the G77R was modified slightly to increase the total impulse. The NAR-certified version now develops 105 N-sec of power. It ships with a color-coded bondable aft thrust ring, a FirstFire Jr. igniter and is priced at $19.99 each, in delay times of 4, 7 and 10 seconds.

A new motor closure adapter for the previously-released EFC-1™ Electronic Forward Closure™ was shown, part no. EFC29-4. This adapter allows the use of the EFC-1 with the model rocket RMS-29/40-120 hardware, further expanding the versatility of the electronic delay timing device. The EFC29-4 is available now at a suggested retail price of $24.95.

Next, Gary unveiled to NARAM-48 participants a new 29mm single-use 'G' motor, the G79W (P/N 77904, 77907 and 77910). This motor is a White Lightning™ equivalent to the G77R and delivers 112 N-sec of total impulse with a burn time of 1.4 seconds. Like the G77R, the G79W is shipped with a color-coded bondable aft thrust ring, a FirstFire Jr. igniter and is priced at $19.99 each, in delay times of 4, 7 and 10 seconds.

For the past year or so, AeroTech has been working on a new type of rocket motor concept called the Loadable Motor System™ or LMS™ (patent pending). The LMS was going to be applied initially to the AeroTech model rocket motor lineup in the form of a Limited-Use Reloadable™ (LUR™) F20W Econojet™. Plans change, and the first motor to benefit from the new motor technology was the LMS K250W released earlier this year. The LMS idea was then reapplied to the F20W and resulted in the development of F20W/L LMS motor kits (P/N 61904 and 61907). The F20W/L is a 2-pack of F20W motors in kit form. They are easily assembled in just a few minutes with 5-minute epoxy. The F20W/L motors kits are priced at $27.99 per 2-pack, a savings of $4 over the assembled equivalent Econojets, and are shipped with color-coded bondable aft thrust rings. A key advantage of the LMS is the ability to change or modify delays, and the appropriate delay kits are specified on the LMS motor kit instructions.

Gary mentioned that AeroTech dealers have been requesting a means to ship motors larger than the F20W and F42T Econojets without a hazmat charge. As a result of this customer feedback, AeroTech has redesigned and recertified the popular G64W RMS-29/40-120 reload kit as a 2-grain design, which can now be shipped USPS Parcel Post® with no hazmat charge. Price and delay times will remain the same.

There was "one more thing". AeroTech has applied the LMS concept to the G77R and G79R designs, and is releasing the G77R and G79W in LMS motor kit form as the G77R/L (P/N 77604, 77607 and 77610) and G79W/L (P/N 77804, 77807 and 77810). These motor kits produce identical performance to their preassembled counterparts, but at an even lower retail price of $17.99 each and are the only 'G' class single-use motors that may be shipped via USPS Parcel Post® with no hazmat fees. They also include the color-coded bondable aft thrust ring and FirstFire Jr. igniter and will be available in the same time delays as the pre-built versions. All LMS motor kits will be available dealer direct only for the foreseeable future.

Finally, Gary revealed that all future production AeroTech 29mm single-use motors will be shipping with color-coded bondable aft thrust rings.

Wow :D

VERY nice :D

I will certainly be flying some of these motors, especially the G77R in the future :D

Very good news :D
 
If possible I might stick a couple of these in my Thumper Jr. 1x38mm 4x29mm cluster rocket with an I284 for a neat flight.

"...AeroTech has redesigned and recertified the popular G64W RMS-29/40-120 reload kit as a 2-grain design, which can now be shipped USPS Parcel Post® with no hazmat charge."

This is great news. Way to go AeroTech. I hope this kind of thinking will extend to other reloads making them easier to obtain. Easier to obtain = more motors to burn....;)

Thanks AeroTech.

So, how does this work? are they keyed so the c-slots line up correctly, or did you redesign them as BATES grains with center cores?
 
I find that awesome that the G64 has been redesigned as a 2 grain motor to avoid HAZMAT shipping!!!:D :D :D

I assume it will be like the G33 where you use cellophane tape to allign the grains.

Thanks again Gary, this is most excellent news!!!.:D :D :D

Thanks Donald, you are correct!!

We found that masking tape works too. :)

You're welcome Gary.:)

Also, has this redesign changed the overall performance of the motor???

Gotta love the G64 and with this redesign, getting it will be oh, so much easier!!!:D

I wonder if this could be done with the 29/40-120 F motors too.

This is great news! Will the new G64W reload kits have a new product number? I want to make sure that I get the new redesigned reload kits.

Best regards,
Brian
 
man this is GREAT! I flew the G64 as my first reload flight and my first MPR flight. making it even better is GREAT! BTW is there any news that AT might make a REDLINE for the 29/40-120??!! That would then make this the coolest most indescribabaly cool case (unlike our weather :rolleyes: )

thanx, Ben

Been discussed before, and was determined that the C-slot grain geometry for the 29/40-120 does not really provide much propellant effect on the redlines the way the bates grains do. I believe this was part of the reason for the development of the 29/120 case/loads. You're right though - it would be awesome!
 
I would think a slight increase because of the extra flame fronts.

Jason
 
The LMS systems sound awesome.

The G77R would be a perfect motor for my Hustler, if there's no wind :D. All these new products sound great!

Thanks AeroTech!
 
Speaking about making reloads Shippable via Parcel Post, I wonder if the 29/40-120 F motors could be redesigned into 2 grain motors and the G33 redesigned into a 3 grain motor.

Now that would be cool.:D

What performance change can we expect from the G64 grain being cut in half?
The 2-grain produces 25 lb initial thrust vs 22 lb for the single grain due to the extra exposed end area.

It delivers 115 N-sec vs 118 N-sec total impulse presumably due to the more regressive thrust curve (which results in slightly lower average pressure).
 
and i thought the old g64 was an awsome motor (my favorite for model rocket only launches) you just improved on perfection!! :)

Same part number. We plan to begin shipping the 2-grain version in the next week or so.
 
So what would be a good way to designate the new version of the G64 fo a Simulation program? G64Mk2? G64/2G?:confused:
 
Wow - that is a MUCH more regressive burn, and a nice high spike to get things moving :D
 
Jason Likey. Jason buy lotsa. Mwa-ha-ha-ha.

Dangit Gary! ;)

We call it G64 bifurcated. You can call it anything you want. :)

Kind of like an F20W on steroids...in fact it uses two F20W propellant grains.

Do the delay kits come in the motor kit?
 
Probably not - my bet is that they use a similar system to the HPR loads...

Each motor kit comes with the parts needed to build the delay marked on the kit (4, 7 or 10 seconds).
 
Gary, do you have the wrasp data list available for those of us who need to manually input the thrust curve in our older simualtion programs?

Best Regards
 
darn...I was hoping to see "RMS hybrid 54mm re-released" in this news thread...maybe next time...

I purchased a package of F20-7W LMS motors from Bill of BMS here at NARAM. He was discounting the price to, I think, $25.60 a pack.

That's, like, less than $13.00 for an 'F' motor. It's been awhile since I've seen a composite 'F' motor at this price.

They work pretty good, too! :D
