Thanks mate, that's kinda where its headed, I'm not sure who the customers are yet but I'm sure there is bound to be crazy people out there willing to pay me for a chassis/trike kit, well see as this next one progresses. I am currently looking for the donor bike in the NC area and not having a lot of luck.
Also to those of you who have access to my google drive, I got off my lazy ass and fixed the gas tank flange issue. The gas tank mount flange (really the fuel pump flange) is located in the chassis folder with all the other gas tanks parts. Please let me know if there are more issues. Another note, since I made this mistake, you need to use the chassis 5_upright 4.asm, that contains all the newest pieces unlike any other main assemblies that might be hidden in those folders.

July '15 Finally found a reasonable deal on a 2008 Suzuki GSXR 1000, I feel bad taking this beast apart as it seems to be in really nice condition but it was the cheapest deal I could find. This one was track prepped and came with power commander, it seems quite nice and only has 9k miles on it. Not much has happened on the chassis front as I am waiting for the next set of fixtures to come back from the laser cutter and a third set are in final design and should be ready to go early this week. Also finally made it out to an SCCA autocross. The trike is reasonably fast because of its power to weight ratio but cornering leaves a bit to be desired, overall I was 12 seconds off the fastest car of the day and about 5 seconds behind the average. On the bright side I got a lot of things that needed fixing fixed, like the loose throttle cable, the unbled brakes, and the unwired rear turn blinker. The people with the SCCA were really awesome, but at the end of the day I was asked not to come back with my trike (apparently people complained because SCCA insurance only covers "4 wheel vehicles"). Even though the outcome was less then I wanted as far as elapsed time went it was a really good learning experience and I gained a lot of knowledge about how the thing handles on the edge...with low quality tires.

What group conducted the autocross? SCCA has a lot of issues with reverse trikes in the southeast.

What's up with the new handle z06lite? Doesn't exactly roll off the tongue.
If you reread his post, it was an SCCA event. He must of snuck up on them to get a day in but was subsequently banned. MAN! I wish I could gotten a few runs when I attended an event some time ago. I was dismissed without anyone even looking at the trike.

My account was hacked on another forum, so I thought it would be easier to change e mail address and screen name on all the forums I visit.

August '15 Got some real progress done today with the help of my friend Tony. The whole front of the chassis is done now, the fixtures for the back end will be sent to the laser cutter this week hopefully if the friend I have helping with them gets the back one done. I off handedly gave it to him as something to do and it turned into a monster that includes both the lower and upper shock mounts, all the rear bars, and the gas tank mounts. The chassis weighed in at 69.6lbs with my super accurate scale, the CAD model says it should weigh 71 lbs at this point without any weld weight modeled in so that is looking on track. I also pulled the chassis out of the jig to make that would work and then set it out next to the current trike to get a feel for size and look. I sat in it and realized that I hadn't accounted for the driver seat position change with the front roll hoop height, as you now sit between the lower chassis rails instead of on top of them so you sit about 1.5" lower. I am not really worried about it, as I expect that area to be used up by a reasonable seat cushion unlike the current one. The only other thing I noticed as the firewall/seat back is really wide, just as it is now, might look into bending the upper side tubes just forward of the drivers shoulders to decrease the width in the future. Overall I am very pleased with it, lots to do though. Anyone wondering about cost, the table ran me about $1500, and I expect to spend about $1000 on fixtures. For those of you with access to my google drive, as soon as I release the rear end fixtures to the laser cutter I plan on dumping all the chassis/table/fixture files in there for you.      |

Can I please use a cad picture of your frame and give credit to spartan trikes.
I am building a 3 wheeler in a sportsman sprint car frame all electric motors in hub.
Thankyou

Robert,
Not sure if you're asking for a picture, but there is a recent one on page 17 that you can use. Why the sprint car chassis?

Hello, Andrew.
Can we see a video with your trike ride?

For those with access to the Google drive I have changed some things around, I dropped all the files that were in the folder into a sub folder called 2014 vehicle and now there is a new folder called 2015 vehicle that has the new chassis, table, and fixtures. This is a work in progress but the parts you see are the parts I am using, some have not been made yet and I will update as I find problems. An easy one is the front hoop/bell crank fixture in the model no longer represents what you see in the pictures on this page as I changed it where I saw the need to add more. Working on the movie Vilzer, been busy, it will be up tomorrow hopefully, I am just doing one with my best time. Beyond being busy I also shot the film in 60fps which is giving me a lot of issues just trying to get a way to play it back properly. Look for a link in that previous post. Video is posted on the autocross link, repost below. www.youtube.com/watch?v=iTVFvJDQAjYAndrew |

Hey Captain, how are you?
Just watched your last video, awesome.
I see in your video your head sits high in the trike, the wind hitting your head at speed must drive you insane. In my trike my head is much lower and I also have a windscreen of sorts, but if I don't have a helmut on the fatigue from the wind exhausts me and I mean I am buggered after a couple of hours. How do you find it?

Ned,
Yeah I have noticed that the wind is a bit of a problem at high speed, and if I put my hand up at a 90 degree angle off the top of the gauge cluster I can minimize what I feel on my face. Not sure how to deal with this in the immediate future, honestly it doesn't affect me that much. If I went lower the trike would be longer, this would all be easier if I wasn't so tall. I have much more of an issue with my ankle trying to keep my foot of the gas pedal, after 30 minutes or so it starts to really hurt holding your foot at an angle.
Vilzer,
I do use solidworks.
Andrew

Do you have problems with SW? When I design three wheel motorcycle and try to make "live" suspension a have many problems, like freezing, crushes etc. Sorry for my English  |

Andrew With the height of your cowl, a very small piece of flat plexi, to be viewed over, not through, could make a lot of difference without much affect on forward vision. It would be easy to experiment with size and angles. As you already have a lot of flat surfaces, it would integrate just fine. Besides wind, it would also help against gravel and keep your helmet visor free of bug juice. My shield is several inches below my line of sight, yet I can cruise at highway speeds wearing a baseball cap (bill forward) without fear of having to pull over to retrieve it. Does your state require a helmet for trikes? |

Triple,
I realize the idea behind it, just making it look good, not like its an after thought is my current stumbling block. I am required to have a helmet in NC, I would probably wear one anyway.
Vilzer,
I don't get to many crashes, but the number one thing that has helped me is to separate individual parts into sub assemblies. Before I did this the vehicle assembly was probably around 4-500 parts, afterwards its down to about 30 sub-assemblies, so there are way fewer mates in the main assembly which severely cuts down the calculation time when you move something. So when I do my a-arms now the rod end without the ball is included in the a-arm assembly and the chassis/upright have the ball in their respective assembly. So when you go to put them together its very straight forward as solidworks views assemblies in other assemblies are as immovable parts. This allows an a-arm to be placed with 3 coincident mates; one each of the balls and it becomes very easy for the computer to work out its motion path. Since I had started doing that looking at motion paths of the suspension is a breeze.
Andrew

Gettin caught in the rain is a B-I-T-C-H. Pena coladas are alright though.
Your build techniques are looking very sophisticated and impressive. Thanks so much for keeping us in the loop for serial no. 00002. or is that prototype no. 2?
Also like the look of the new skin (ciber depicted). Stressed?(not you, the skin) What material and attachment techniques do you have in mind?

Hello Andrew
Your new project is looking very good. Very professional have you sold any frames yet?
Question for you - what is the top speed you have done in your trike?
I find with mine which is an FJR 1300 which as a Motor bike Yamaha state top speed is 249 KMH or 155 MPH. With the added weight of the Trike frame and everything else to make the Trike a Trike my top speed is around 170 KMH maybe 180KMH or 111 MPH.
Now it gets up to speed quickly when red lining at around 11000 RPM, it just runs out of legs in top gear.
I am very interested in what yours does and any suggestions you may have to increase top end speed.
Regards Ned |
