No problem, I'll run another video without the SAS stuff. 'Probably going to take 5 or 10 runs to get the car sorted and get through the course explosion-less. Your run was pretty smooth; little wiggle right before the launchpad had my heart jump. Also, I like how the tunnels naturally enforce maximum vehicle size. We need to get more exposure so we get some more racers - maybe need some crossposting. ==Only a few things you gotta do everybody== -replace your persistant.* file with Azimech's to get the flags to show up. -watch a video to clarify the route -make car, determine class from original post -record, dump on youtube (I turned off video comments because other youtubers aren't gonna care), post here. ----- Edit instead of double-post. Here's a decent run without SAS. Class 4 again. Took the side of the runway and stayed more on the road like in your video.

@Azimech I made it. Rear wheel steering y'all. 'Not proud of the squirrely car or the terrible driving, but I did complete the course. Cone 11 I went inside instead of outside, spose you could add 2 seconds for that. Everything else good? Two comments. Flags/cones are hard to see. Need to be brighter maybe, not sure what's possible. And class 4s 'no aerodynamics' is a little non-specific. I took it to mean "no additional downforce" 'cause technically a nosecone is an aerodynamic item. Fun stuff man.

So many failed attempts (class 4). 'Think I have the track memorized though.

Looks badass, and new technology is always exciting. Thanks for the video.

Ok, I had to keep the probe upright so the controls weren't messed up. I'm not up on helicopter physics, but when I pitch forward it rolls to one side and backwards vice-versa, so much that control is bad. No successful landings yet (sorry, Jeb). Coaxial might fix it.

'Gonna try the same setup rotated 90 degrees to see if I can do a 1 reaction wheel mini-copter. Glad it wasn't just me. Took forever to figure out what was going on.

'Just tried it quick. Fast to 30m/s (stall) if i hold straight, but barely 35m/s in level flight. He's just so heavy - had to put him right on the center of mass for balance.

Imagine the box it came in! He could sit on top, but he wouldn't make the tunnel

-------- k while I'm here I rebuilt my single juno turboprop island-hopper from scratch and wanted to mention a few things. Here's what I learned this past few days. Maybe it can help someone. -I was unable to get anywhere near 50rads/s with rigid attachment on any rotating parts. 'Still weird to me. -That nosecone in the picture makes an ok blade - low wind resistance for the diameter, pretty lightweight, and only one part. -I didn't need a battery on the rotating unit - a probe core can still manipulate blade angles while under hibernation using almost no juice. KerbalX k on to the next thing

I wanted to see if I could get Jeb's fat head off the ground with only 1 small reaction wheel. You can, just barely. If he's not riding along its actually an ok plane. I floated RCSs balls inside 4 snapped thermometers like on the motorcar. You could double the motor output on this plane with another reaction wheel since 1 generator will power 2 of the small SAS units -if we wanted to make this more usable. 'Could also probably lighten the load by dumping the spotlight and/or converting to battery power by removing the generators. I discovered some weirdness in the meantime I wanted to share. I was unable to get enough power on my motor until I turned off Rigid Attachment. So odd. If I unchecked rigid attachment on all the items that rotated (props, cone, generator, etc) then my RPMs and power went way up. I didn't test every single part individually - maybe you guys can help me test this problem on your own rigs. This had me scratching my head for a while wondering why different versions of this same plane had different power levels. KerbalX I think you did! Those are some speedy planes.

'Would be more pleasurable if the pictures were embedded so I didn't have to click on each one. I dig seeing these. Thanks for posting.

Word up, G. I agree. How about a more complicated version of this for the turret? I angled some solar wafers so the stayputnik ball wouldn't pop out - it limited the range of motion tho. Very few parts total. Keep at it.

Guys, we got another one! It was pretty awesome of you to take the time to make this posting with all the separate pictures and explanations. I'm going to re-read it a few times. Working under the constraints of a replica really must have added to the total project time. Not to mention dealing with small parts. Hinge w/ hydraulic lever = hot!

No, but since you mentioned them maybe they'll come visit. I was thinking today, if they made a size or shape change to certain items a lot of our stuff would be broken. Dear Squad: send robotic parts. Everyone's invited! Come on in. Grats on 200 uploads BTW. Azimech will hook you up.

Thanks. My bad.

The Top Gun plane, ya? Not too bad. Welcome to the forums. If you make more stock planes we'll gladly take any pics you post.

I saw this floating around on kerbalx but didn't feel experience enough with rovers to comment. I do like the style though. The dual wheels are neat and it looks efficient and practical.

'better fly over a ladder truck inside a cargo plane. Send pics if you do. We're proud of you, sir - a true engineer.

Sorry, have to send you back to the turboprop forum. I haven't done any big stuff. I have faith in you though. Keep us updated. We'll see you there.

Hell yeah! Just offset the blower so it blows more on one side. The further out, the better. I put a plate under this car in case the bearings wiggle and the blowers miss the battery and try to flip the car over :-0. There was a short discussion buried in Azimech's turbine/helicopter forum about how much torque/power you get based on the diameter of the blades (-further is way better- is what I got out of it). Batteries are pretty light (shouldn't be imo) and one middle size battery makes a great blade I think.

I was pretty sure someone somewhere had used the RCS ports before and didn't want to make any claims because I probably got the idea from somewhere on here or at kerbalx. I will go search out the Canadarm (sounds familiar). I had some jimmy hinges on here when the car was smaller, but with size and feature creep I was out past their maximum scope. Thanks for the kind words. Glad you like it. I've been able to get myself to the mun and minmus after watching Manley's videos and reading about how to change my orbital inclination. It's been a few months since I've been up there though and would like to send a probe to duna some day. The high difficulty (for me anyway) and pre-planning and testing for a future duna trip is really going to make even a partial success feel amazing. But I gotta check out some of these boats people are making first :-).

I already made a car, but I wanted to make a smaller one I guess. This one ended up bigger than planned but after many days and many revisions I had to button it up. Now that 1.2 let's me float parts (offset w/shift button) more things are possible in stock. Everything on this car is shift-offset or offset then rotated. The front end is lowered a bit for looks, but ground clearance is poo now. Car is so long that turning radius ain't good. But on the plus side- this motorcar has a full steering rack! I laugh to myself that the steering column is an actual column :-) I used linear RCS ports (take note engineers, these are nice and smooth and round) surrounded by 6 thermometers for the bushings. 3, 4, and 8 thermometers also work. Angling them slightly too can help hold the balls in place, although I didn't do that here. gears on solid axle - after multiple days of trying different gear combinations and bearing sets I settled on this single step final similar to the piston car. The engine isn't torquey so I needed the largest stepdown I could make. Obviously you can't make the final gear larger than the wheel, and a large wheel negates the stepdown :/ The axle shafts are little antennas surrounded by the smallest solar panels that just make the right sized hole. custom wheels - a morgan type wire wheel up front and solid wheels in back. RCS ports have high tolerance and the friction was good enough. and a working hybrid turboshaft-crankshaft engine with pulsing exhaust. 8 junos tuned down to blow on 4 batteries that are offset from the center to appear like a crankshaft. Let's just say this did not help with balance or high rpm performance. Bearings are my old standard, the avionics cone pds314 showed me, stuck in a hole made by 4 octo struts. the exhaust is thrust limited to 2.5, the minimal setting where they still set off a puff of flame (6.5 is the next faster puff btw for you aesthetic enthusiasts). If you stage them all separately they puff at off times and it makes it look like cylinders are firing! I am very proud to be presenting this and hope you enjoy seeing it. Cheers to all the engineers I "borrowed" ideas from. KerbalX

Wings angled down, bigger gear in the center, takeoff-assist rockets - looks proper, good job!

A while ago when I knew jack beans. Seeing it now, it's so nice and compact. Neat to see the progression. How is the project now? I would think Rigid Attachment would help some. With landing gear having high tolerance I wonder if that could help get your track to the ground. giant chain Getting this downsized is gonna be work. If this gets momentum we'll need a new thread started (or if there's an old one we can revive).
