arthurmoto1 Posted February 16, 2021 Posted February 16, 2021 Hi all! I'd like to show you the process of 2-seat paratrike building with brand new Simonini engine. 3 Quote
alan_k Posted February 17, 2021 Posted February 17, 2021 Minor point possibly, why is the arc of the propeller so much higher than the top of the frame? Quote
arthurmoto1 Posted February 17, 2021 Author Posted February 17, 2021 It will be used a separate guard for propeller. But there is an intention to connect the top of the frame with the front part with two tubes to make some kind of crate to protect people from any side in case of the crash. Like buggy has. Quote

arthurmoto1 Posted March 11, 2021 Author Posted March 11, 2021 Brand new Fluidyne radiator from 1000 ccm Can-AmATV has arrived. Quote
arthurmoto1 Posted March 17, 2021 Author Posted March 17, 2021 We have DIY tool and accordingly DIY propeller 2m diameter guards now. Were trying to use it like hulahoop but not successfully. And there is front wheel with brakes and suspension (the half of Mercedes Sprinter front spring). As for me I'd rather use hydraulic motorcycle brakes but the customer insisted on bikes brakes personally I think are useless at all to deal with such weight. Quote
arthurmoto1 Posted March 17, 2021 Author Posted March 17, 2021 And here you can see the common weight measuring of Ukrainian Airlines pilots before flight on Boeing. 1 Quote
Blackburn Mark Posted March 24, 2021 Posted March 24, 2021 That looks like the kind of thing you could hit a brick wall at 40mph and walk away from.... looks pretty heavy though Quote
arthurmoto1 Posted March 24, 2021 Author Posted March 24, 2021 Yes that's it! Actually the tubes are paper thin but of large diameter. But the is a problem they react on welding so much we have to correct geometry every time after welding. Quote

I'm assuming that's stainless tube... what wall thickness and did you roll those shapes yourself? I would think its pretty tough to get a curve in such a large diameter, thin wall stainless tube.

arthurmoto1 Posted March 24, 2021 Author Posted March 24, 2021 Yes this is stainless tube with thickness of wall approximately 1.5 mm. This is not a huge task to roll the tubes ourselves and we have DIY hand tool I'll show you soon. 1 Quote

arthurmoto1 Posted March 26, 2021 Author Posted March 26, 2021 Sorry it's too late! My buddy gave it back to the metal workshop. But I can tell you it is very simple and consists just of three rollers and motor that drags the tube. Your task is to move the middle roller with the screw during the process. And the tube is of 52 mm diameter and 1 mm thickness (I was wrong about 1.5 mm). Quote
Blackburn Mark Posted March 27, 2021 Posted March 27, 2021 (edited) No worries, I know how they work, I am just surprised you got it to work so well on 52mm stainless. Good luck Edited March 27, 2021 by Blackburn Mark Quote
arthurmoto1 Posted March 28, 2021 Author Posted March 28, 2021 The rollers have to be done with proper accuracy and after the binding the ends of tube (20 cm) are junk. Quote
arthurmoto1 Posted June 13, 2021 Author Posted June 13, 2021 Good news! It flyes but engine is a real beast! I think we have to make something to switch off one cylinder in the fly because it is too powerful. Wait for video. It is enough to have the engine just idling to move but 1/2 throttle seems to make possible to turn trike over! Quote
arthurmoto1 Posted June 14, 2021 Author Posted June 14, 2021 First fly short video https://www.youtube.com/watch?v=7S07EzjMmos 1 Quote
admin (Simon W) Posted June 16, 2021 Posted June 16, 2021 Congratulations!!! It looks like it flies brilliantly!! SW Quote

arthurmoto1 Posted November 1, 2021 Author Posted November 1, 2021 There are bad news- the leg was broken during landing because of concrete part in the grass. And good news - there is new front end with suspension now! But I can't attach photo... something is wrong. Quote

You can only post so many images, then you are kind of out of storage... Its quite debilitating! I am sure Simon or the software has its reasons for limiting image uploads but its not fun for information sharing. Quote
arthurmoto1 Posted November 4, 2021 Author Posted November 4, 2021 Oops! But we can make video! Quote
