Re: Devilish Project (Go Devil 38 kit bash)

Mine was single break / dual deploy with a cable cutter. Raven and TeleGPS in the nose. AeroPac Min Dia Retainer, 3 layer 200GSM airframe, G10 fins with CF over top. Here are the stats from that flight. TeleGPS put my max altitude at 17,507 ft. Max velocity was 2037 ft/s or roughly Mach 1.8. It also...

Re: basalt fibre - new material for me

TBH OTT I don't think this is necessary, unless you're going to use Wests on those fin leading edges. :wink: Interestingly, I am considering Wests for the LE (and fillets)! An idea is percolating currently and I actually think it will work. FYI, in the past I have had Wests fillets to Mach 1.8. For...

Re: Devilish Project (Go Devil 38 kit bash)

Gotta admit, I'll be mightily impressed if you can break Mach 2 with a 38mm vehicle OTT. My 38s rocket didn't crack Mach 2 on a J510 and it was heavily optimised and used a lighter airframe than what you're using. Still, it's worth a crack!

Tested at BALLS 2017

I found this video quite humorous, especially the reactions Simone has to various issues. it's always curious to see what "average people" think of our pursuits.

Re: basalt fibre - new material for me

Thanks for the info Drew. So was the 3600 on the leading edges? Or were the leading edges bare fin material? If so, G10 or CF sheet? Thanks My pleasure OTT. Yes on the 3600 leading edge for my vehicle. I know my fins were stock standard G10 (scavenged from a Performance Rocketry 3" kit) with a...

Re: basalt fibre - new material for me

Any suggestions for coatings there HI? I am building a couple of rockets for the Mach 2+ area (I hope) so I'm considering what I might coat the leading edges with. I suspect I am not going to need anything too special at that speed. TBH OTT I don't think this is necessary, unless you're going to us...

Re: Solar thread

uh no, you don't want to do it that way :roll: probably saves (them) on cabling and isolation switches or something... I'm obviously no expert but from what I've been told having your array wired in parallel will only allow you to produce as much as the weakest panel produces. So if you have a sing...

Re: Solar thread

Cheers for the response. Quick update, I'm locked in for an install in January. Initially I had SolaHart come out and quote but they tried to take us for a ride. I then rang up Infinite Energy and had them quote. My experience with them was great. They quoted us three options. The top shelf solution...

Re: Taipan 38mm Min Dia Build

Tell us about he kit NL. I found a previous post from Blake that this is roughly equivalent to a BlackHawk. I cannot see the kit listed unless I do a search but that comes up with no details and a $899 price tag, which I thought a bit was excessive for a MD 38 unless it was gold plated. I know Blak...

Re: Taipan 38mm Min Dia Build

Question: do I use masking tape to fill in the coupler gaps to form a firm fit? If you're referring to the NC/body tube coupling joint then yes, just use some masking tape (preferably blue tape) to provide a snug but not too tight of a fit. And if you're really going to push it I'd recommend incorp...

Re: Solar thread

Tesla PowerWall 2's are very expensive (14kWh, $10k~$12k) My power bills average $600 to $700 per 60 days. That's f'n ridiculous and stupidly expensive. So back of the envelope, say if I drop my power bill to somewhere around $200 per bill I'd save ~$3,700 per annually. So I'd pay off the PowerWall...

Solar thread

Long story short; I'm about to get solar for my house. Any recommendations from you knowledgeable lot? I'm sure there's an expert in here somewhere. Effectively my only comments are that I want my install to be "battery ready" so I can plug a PowerWall 2 into it once they finally arrive do...
