Re: Launch Dates 2021

As a public service, any chance a message could be posted here if any decision is made to cancel tomorrow morning. I’ll get my son to periodically check my Tapatalk feed as we drive down. Frustrating if I don’t find out till I get to the gate - it’s a slow 2 hr drive home. Sent from my iPad using Ta...

Re: Level 2 build

I have one of these Harm motor adapters you can borrow if it is suitable https://www.sierrafoxhobbies.com/en/motor-retainers/1065-motor-adapter-hamr-5438-public-missiles-ltd.html Thanks for the offer, but I’m uncertain if it will work. The rocket has a glass boat tail with a slimline retainer and s...

Re: Level 2 build

I’ve finished a 3 inch Mac Performance Firestick XL (54mm). But I wanna fly it on a 38mm motor for its first flight and have been waiting to hear back from Blake about 54/38 adapters. I finally gave up and ordered from Wildman, but not sure it will arrive in time. I’ve got a 54mm Wildman Punisher sp...

Re: Level 2 build

Yeah, the weather forecast would suggest that at best we will have cloud cover and maybe worse. I had to convert 1360m to feet and 4600ft is likely to be out of site. I’m also considering J motors for a couple of rockets for the weekend, but the weather will def play a role in the decision and also ...

Re: Level 1 rocket kit

My 20c worth would be a question back to you. Do you have any fibreglassing or composite experience and/or are you set up at home to use said materials. If not, build a cardboard rocket. LOC has any number of options as do most of the major retailers. They go together with wood glue and cleaning up ...

Not sure your average rocketeer has a lathe - but I could be mistaken.

Re: Ejection charge cap

Dodgy cheap Jaycar PLA that I’m trying to use up before I open the better stuff that I’ve since bought. Chuck on TRF, one of the admins and the guy who posts a lot on the 3D printing forum, did a big review last year comparing PLA, PETG, and ASA upto 4g charges and found A) no signs of damage and B)...

Re: Ejection charge cap

Food for thought. I’ve spent the last few hrs doing ground tests for my new 3 inch Macperformance rocket. The online calculators way underestimated the required charges so wound up doing 5 each in the booster and payload sections. https://uploads.tapatalk-cdn.com/20210131/b6bd2680992dae0b022b156ab4c...

Re: Ejection charge cap

I do a session and make several all at once in common BP amounts and keep them in my launch box with a label on them

Re: Ejection charge cap

Traditional route is to use some sort of pre made aluminium canister like these https://uploads.tapatalk-cdn.com/20210129/011d12caf61f1d5400d002b1efe0da31.jpg However, they are not available locally so you either buy from overseas, or find something else that works. I’m currently experimenting with ...

Re: Motor Size Recommendation for L1/2

So I just looked at that kit on the sellers website. A 2.6 inch single deploy quantum tube rocket is going to go very high, very fast on a J motor. I flew something similar at NZRA last year that I converted to dual deploy and it went 5500ft. So you can’t Cert 2 on it at Cedar Grove. You would need ...

Re: Motor Size Recommendation for L1/2

Which club do you fly with? If you are in QLD and will be getting DMS motors from Blake, they are all Aerotech and all have thrust rings built in. Who sold you the kit? Sounds like the sort of Q’s you should have been asking before you purchased it if you plan on certifying level 1 and level 2 with ...
