alan_k Posted February 17 Share Posted February 17 Minor point possibly, why is the arc of the propeller so much higher than the top of the frame? Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted February 17 Author Share Posted February 17 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.

arthurmoto1 Posted March 17 Author Share Posted March 17 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.

Blackburn Mark Posted March 24 Share Posted March 24 That looks like the kind of thing you could hit a brick wall at 40mph and walk away from.... looks pretty heavy though Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted March 24 Author Share Posted March 24 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 Link to comment Share on other sites More sharing options...

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 Author Share Posted March 24 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 Link to comment Share on other sites More sharing options...

I have made one myself but for smaller size aluminum tubing / used it to build a new prop cage. Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted March 26 Author Share Posted March 26 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 Link to comment Share on other sites More sharing options...
Blackburn Mark Posted March 27 Share Posted March 27 (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 by Blackburn Mark Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted March 28 Author Share Posted March 28 The rollers have to be done with proper accuracy and after the binding the ends of tube (20 cm) are junk. Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted June 13 Author Share Posted June 13 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 Link to comment Share on other sites More sharing options...
