That was a brilliant launch. Loved the ring of dust as the motor ignited at ground 0. Totally awesome guys ....good attempt.

For checking the root for contact couldn't you put a thin coat of paint...

I think he means taught as in tight lol

Should I then fill the hole with epoxy after that ?? This isn't classed as altering the motor or anything like that ???? Dont want to do any hazardous stuff LoL :)

Hi everyone, I've a F20 ecojet single use motor that I want to use but it's a 4 second delay and I'm putting it in a min diameter rocket with an RRC2 for deployment. I want to do away with the delay...

Thanks Neuport I've just ordered exactly what you suggested. Its a 4 ch one but similar to what you said. Cost me $14.00 :)....much simpler cheers

So basically, line your motor as an insulator if your in the slightest not sure. If you don't line it then the first burn might be ok as a single use motor but the heat will undermine the integrity...

In Scotland there are a lot of species that are endangered including the pine martin , wild cat , otters and badgers. I'm a game keepers son and had an active life in the country with masses of time...

I've been following the series called Finding Big Foot !!!! For you who dont know it's an American based series where there following leads and sightings of them......Is this a myth or what ????

Has anyone built a Radio controlled launch controller.

My plan was to have a control box that could be set up beside my launch tower and crocodile clipped to a 12 volt battery beside it.
The...

I'm not wanting to hijack this post but in Britain it is legal to use quick match which burns from 100 to 300 ft per second. If you drilled a small hole in the delay grain and inserted the quick...

:lol:

Congrats Shane, hope mum and wee one are well. Its a lovely name they chose too!!

What do you mean BLKKROW ??

Thanks for the post Gerald

Using a plane would remove the ability of hovering and capturing good still photos etc.

I flew helis for a good few years. Compass Knight 50 I had. It was a fully 3d chopper and a total dream to...

[QUOTE=troj;378106]The liner is indeed an insulator, and the insulation required depends on the propellant and grain geometry.

This is why you see different liner materials for different reloads....

Hi everyone, question about the liner that you insert into the motor housing. I was wondering what its full purpose in life was. Does its roll cover more than just an insulator or is that its primary...

Ok I masking taped out the N.C on the rocket and its very....very tight almost to tight I thought.....:eyeroll:......I can pick the thing up by the N.C and shake it all day long and it doesnt move. I...

I agree, I wouldn't dare pop the main on my 3" at 500 ft either but maybe a smaller 1 1/2 " rocket

Ok I have checked and the profile switch does hold different memory perimeters but just changes the 500 ft and 1000 ft main deploy. This is very handy so you can program it for 2 different rocket...

I had been wondering about this to a lot. This post is very helpful as I'm just starting DD and I wasn't sure what direction to go with the motor delay grain but now I know I'll just let it do its...

So the profile switch does hold different set up instances on the programming ????

I'm going to check that by programming in two different setup's to check as I've had two different answers on...

Thanks everyone, Ill make the N.C as tight a fit where I can pick up the rocket by the cone and ground test a charge to see what happens. Ive never done this before so kinda excited :) always relied...

Thanks for the response guys. I'll set the mach inhibit to 4 seconds unless burn time is more than 3 seconds and the dip switch I'll set to 1000 ft

Thanks for all the replys. I am going to vent the avionics bay with a 1/8 th hole. With the ground testing of the RRC2 how do you actually get the charge to fire???? Do you try to fool the RRC2 into...

Cw, the rocket is 5 ft long and 3.5 lbs in weight. Its a 3" dia tube and will be propelled by a 300 n 4 grain burn hitting .5 mach. I dont have the experience to know if it will drag separate or not....

TYPO error sorry Pro 38mm ......:(

Hi everyone, I've a 3.5 lb rocket which Ill be putting up on a 32mm 4 grain reload and its going duel deploy on an RRC2. The rocket will part come apart in the middle deploying the drogue and then...

Hi everyone, couple of questions about my RRC2. I have the programming of the unit figured out now and it's pretty easy once you get an hour to get it to sink in. On the unit there is a set point to...
