it just lets you buy commercially made rocket engines exceeding like 320 (this number might be wrong) Newtons of thrust

To be fair, the competition charges $12,000 (last time I checked and that was 10 years ago). :o , and to think we WERE going to offer a 3D Spudgun simulation software for free, pfft and sry for all these side questions, but do you actually have rocksim?, also do you have your high power rocketry li...

my thought track was tho, the lawn mower cant cut back its fuel usage compared to its output, so to to this you would have to manually cut back on the liquid fuel when u add the gaseous fuel to actually see a performance increase. But, im looking up propane engines right now.

lol, that shot at 1/4 speed reminded me of transformers

but, i do like your setup of the gun, but i want to see it with DIY's suggestions

hmm, i think that this would not occur because i thought it was only a danger in pressure applications, also a thin layer of oil should be present blocking the gas from touching the cylinder wall anyway, isnt there? i could be wrong thats just a guess Edit: the problem that we'll have with the mower...

ok sweet, do you plan to soon?, and im glad to see im not the only one that wants better gas mileage

so i was wondering if anyone has a HHO gas or Browns gas generator in their car to increase milage. I am currently doing research into it (so i thought i would ask u guys), some say fact some say fiction, but i think im going to try it on a small lawnmower engine before i try it on my car just to se...

i would coils but i dont know how to hook them up i just know they work for metallic projectiles (soren used a tater with metal and cronyed it with coils)

It does offend me that they're charging so much for the new version, but I suppose I should have seen that coming since they WANTED to charge that much for the original Splash (but I vetoed that on principal). half the price i might understand, but 1 grand is just outragious, IMO and just as a side...

ROTLMAO..... I'll give you three guesses who wrote the 6DOF package for RockSim Pro. Hint: It used to be called "Splash." Then the source code was sold for a nice little sum and rolled into RockSim to become RockSim Pro. ....That said, yeah, it oughta work nicely for the design of low drag projecti...

hmm

Yep. Amazing how few people in this hobby actually realise that... And the threads are 1/4" compression, nice and convenient.

i wished i knew that a while ago

*wishes he had and Iwoa class Battleship*

lol, ppl would think its raining nukes if they fired this on land

but for noisemaker, maybe but a ballon of oxygen, and 1 ballon of acetylene in a trash-bag, then shoot the trash-bag with a sparkler?


Edit: i just realized i could fit in the barrels

it is fairly accurate with the rocket launches as it is a "3 degrees of freedom" statistical modeler, so i would say that its Cd measures would be very accurate

make sure your are also moving the velocity up from 0 when you are checking the Cd

BTW, i would go green if you can cause i think the human eye is most sensitive to the color green
