Re: Devilish Project (Go Devil 38 kit bash)

Looks good OTT. I especially like the stud, I toyed with the idea of doing away with the eye bolt in the purple parrot, but I figured I actually need the weight to get me up to optimal and it doesn’t take up too much room. I’ve thought about building a stretched version of the purple parrot, would p...

Re: Scratch built X Wing

Nice rocket. Nice flight. You have to be happy with that Mat! Yeah it’s pretty sweet, pictures like that are the icing on the cake OTT. Unfortunately this time it was coming back down when the ejection charges went off and shredded the chute. Fortunately it has a pretty decent set of wings so did a...

Re: Scratch built X Wing

Not sure where the year has gone. Anyway here is the X Wing in full decals. Planning another flight on a Sunday for QRS Christmas launch, should be good. https://farm5.staticflickr.com/4531/38042857025_939662bf40_c.jpg Untitled by SpaceManMat , on Flickr https://farm5.staticflickr.com/4680/271531712...

Re: Payload for First Falcon Heavy Flight Announced

I don’t ever recall hearing any explanation from Space X about dumping cross feed from FH. Just figured they though the complexity and extra equipment wasn’t worth the rewards and throttling Center core engines would be a reasonable alternative.

Re: Payload for First Falcon Heavy Flight Announced

The issue is prior to staging as the tanks empty out the mass of the rocket is greatly reduced so the accelleration starts to run away unless you do something about it such as throttle back. This is why the Saturn V used to cut the inboard motor prior to staging, otherwise to Gs would get extremely ...

Re: basalt fibre - new material for me

Don’t think you’ll have issues with flame reaching the fine with that design. If you did the limiting factor would be the resin not the cloth.

Re: Ooops. Wrong launch site

It weird that even while it could not get a fix it still tried to perform a burn. Should have simply stayed in orbit and reported an issue.

Re: Payload for First Falcon Heavy Flight Announced

Amusing, but you can’t just decide to do that. Anything going to orbit needs to carefully designed for that part of the trip. You’d have to do a ton of work to make it happen and a non traditional payload would add risk to the mission. Nice PR stunt though, ceartainly get a few people talking.

Re: basalt fibre - new material for me

A quick read on Wikipedia, seems it should be fine. Looks around the same density as fibre glass but has superior properties, typically comes with a finer weave cloth. Apparently not as good as carbon fibre though. Guess if you wanted to take advantage of its properties you would make thin wall tubes.
