Anyone know where to find AT G8 motors?

I can’t wait for them to come out! Here’s an EasyMini (with battery) and tracker inside of a 3” x 29mm coupler. Rocket weight is around 4 - 4.5oz without motor.

When I first read that I thought you meant cluster. Now that's something to look into. If you could just keep it light enough.

Pretty much just need the nose cones, leaves options for selecting your own components by mass right?

Apogee 29mm BTs that exactly fit the Aspire nose are the lightest 29mm I know of. The matching coupler is similarly light.

How 'bout something like this?

I emailed him. He is going to add it in the coming days. I thought he said he already had.

Pre order @ $22.49.....https://www.balsamachining.com/#

Nice, I got one pre ordered, that hazmat shipping is like 2x the motor price!

Ouch...

Name of the game. Find a local vendor or order more than one at a time.

Otherwise you're flushing money instead of burning it (out the back of a tube)

Not if you buy more then one at a time!

It's a cool motor - buy a bunch, and then add whatever other reloads you need to restock to your order.
Next thing you know, Hazmat fee is a rounding error!

Hmmmm, wonder if one of those could get my upscale Quinstar off the ground. How do you judge appropriate thrust/weight ratio for a saucer?

They will be in stock here on Thursday. Subscribe to notifications so you can get yours shipped on Friday.

So 266 grams with the motor for a minimum 3-1 thrust to weight ratio. 130 grams dry weight give or take. With some kind of electronic deployment... Not impossible but darn close to it.

...starts weighing parts....

It's a real head scratcher isn't it. Been attempting OR sims off and on for a while now. Nothing I've tried so far appears good, the fact that it's plugged makes it a real nut cracker. I'm thinking tiny Lipo/alt combo with a 2 wrap 4 oz bt with combined conical nc made from glass or carbon sleeve and 1/16" (possibly even thinner?) fins. I do have some very small batteries but not so as far as deployment electronics. I'd love to see someone make it work. Is lightweight paper and balsa possibly the key?

I was puzzling over the same thing in a different thread.
Someone (forget who) reminded me that these are not intended primarily for traditional use. They recommended them for vectored thrust rockets, or 2nd stage sustainers (where thr/wt only needs to be ~2)

The trick is that the initial thrust gives a thr/wt of 6 on The Motor Alone Leaving you with 2.1 oz for airframe/electronics if you have a Looong rail/rod and can deal with a 4.5 initial thr/wt


Wondering how they'd handle in a boost glider....

I was thinking about putting one in a Rocketarium Turbo Vortico. It’s 92g and doesn’t need an ejection charge.

Thats my plan for this upcoming weekend. Assuming Wildman has them in stock before then

I'm building an appgee aspire with a custom deployment system for it. It's super lightweight and was tested last January. As long as it shipped from BMS, I may be able to fly it in April. Just under 3km!

I’d love to know how it goes. It might be a few weeks before I’m able to do the same.

If you own a Aerotech Phoenix rocket booted glider these are nirvana! I flew a pre-production prototype last October and it was awesome! There are plans on flying up to six Phoenix gliders on this motor all at the same time at LDRS in Argonia.

To all; Let u know how it goes.

Apogee Aspire parts with Bear AltiUno SMT should work just fine I think.
