I am having a really bad time and can barely stand up. Sorry to hear about your back, when you are mobile enough, I would be very interested to know where the CofG of the trike without motor is coming out. I would like mine to coincide with the CofG of the paramotor, ie not to have to change the present foot launched hang position. Therefore want to have an idea where the mount position of my parmotor might be, and see if it is apractical proposition. Get well soon, we're all waiting to know how it flies!

Guy Posted July 25, 2018 Share Posted July 25, 2018 So where should the line of thrust be best positioned in relation to hang points...........what is the perceived wisdom? Am I right in thinking that they should be as close together as possible? Quote Link to comment Share on other sites More sharing options...

I did make the centre tube longer than standard though as I am 6' 4" (the longer length version is shown in the plans). I also used the larger diameter (1.5") as I am 92 Kg and I thought it would also make it more robust. Thanks. I should be able to work it out from the photos. I, too will be using the longer tube and the larger dia. 1 Quote Link to comment Share on other sites More sharing options...

Well if you put the CofG of the trike vertically below the hang points of the paramotor ( note: vertically below as the paramotor hangs, in a hang test without the trike), then the whole when bolted together would leave the paramotor hanging in the same attitude. Of course if it doesnt then you have the option to alter the hang point position on the paramotor arms till it does, but best to try and do it without, in my opinion. Least changed the better. 1 Quote Link to comment Share on other sites More sharing options...
PatPux Posted August 17, 2018 Share Posted August 17, 2018 Hi, Andy How's your back coming on? Hope you get to fly the trike soon . I'm gearing up to start my build very soon.Got a couple of questions Where did you get your axle fibreglass rod ? Have found it OK, but dont like the fact they want as much for posting two 1m pieces as they do for the stuff itself!! I have seen you say somewhere, you are heavy!! So am I- about 105kg. Just wondering whether you have sat in yours yet and how the balloon tyres fare, given they are rated at 55kg max each, which, with the majority of the weight over the back axle (and certainly on landing) will put them well over by about the weight of the paramotor, trike and fuel , 40-50kg between the two . Thoughts? Quote Link to comment Share on other sites More sharing options...

PatPux Posted August 18, 2018 Share Posted August 18, 2018 Sorry to hear you're still crook, I really hope it all goes to plan and you get back on your feet........and up in the air soon Surely you're AUW would be over 120kg. 92kg, 15kg trike, 25kg Paramotor, 5kg clothing, boots equipment, 8kg fuel(say) ......around 145kg. But, granted you have 13kg over me! I am aiming to be under 160kg I have subsequently spoken to Neilzy who had a Grasshopper trike that uses those wheels, too, and weighs about the same as me, and he has confirmed that the wheels coped fine, but he did say they punctured quite easily, although said that could have been to do with flying off stubble. Get well soon, mate 1 Quote Link to comment Share on other sites More sharing options...

After reading about your problems with the fork, I was going with the plate and tube welded fork, so won't need the pillar drill for that. But I still think it would make all the rest of the drilling a lot easier. I've needed one for a long time, so I might have to treat myself! 1 Quote Link to comment Share on other sites More sharing options...
PatPux Posted August 24, 2018 Share Posted August 24, 2018 (edited) Well here we go, the build begins. Main frame completed at just over 4kg with another 6kg of wheels and axles to add, plus other bits and pieces. So looks doable at under 15kg.

PatPux Posted August 29, 2018 Share Posted August 29, 2018 (edited) Trike Build is progressing well. Very pleased so far, looking like I will come in at under 12kg for the trike. http://Liteflyer trike Ive got a couple of build tips on materials. 1. If you order the axle holder tube in imperial 1 1/4" , with 1/8" wall thickness this gives an internal dia of 1" or 25.4mm in metric. This means if you then order the fibreglass axle in metric 25mm it is a perfect sliding fit, with no sanding. 25mm GRP Rod 2. I found these as perfect "grippers" for retaining the wheels in position on the axle. They are normally used on Drone booms (will also use an R-Pin on the outboard end for extra security. 25mm clamp http://25mm clamp Coming in under 12kg http://Weigh In Some lovely welding by Roger, a local welding guru. http://Forking nice welding More photos of build in Album Edited August 29, 2018 by PatPux Added links 1 Quote Link to comment Share on other sites More sharing options...

PatPux Posted August 29, 2018 Share Posted August 29, 2018 (edited) Parajet Macro V2 with Moster Plus. I had 3 M10 internally threaded bosses welded into the base of the Macro. I have also picked up with some HDPE clamping brackets. Yes, tube on top so I could run it through to pickup the back mounting boss on the Macro frame http:// http://Macro V2 Fixing for trike More photos in Album Edited August 29, 2018 by PatPux Quote Link to comment Share on other sites More sharing options...

PatPux Posted August 29, 2018 Share Posted August 29, 2018 Weight check. 45kg on a wheel in this condition, there is a little more to add but should be well within 55kg per wheel max allowable load. http://image 1 Quote Link to comment Share on other sites More sharing options...
PatPux Posted August 30, 2018 Share Posted August 30, 2018 Well, couldnt find anyone to bend the tube, all too scared of breaking it. So in best Heath Robinson tradition I did it myself, using Acrows , scaffold clips, oak packers, sand filling and most of my 100kg on the end of a pretty big lever. Went like a dream http://Sand Filling http://Setting up http://Go On My Son! http://Finished Quote Link to comment Share on other sites More sharing options...

PatPux Posted September 2, 2018 Share Posted September 2, 2018 So in the best tradition of the late Colin Chapman I have spent the day adding lightness, removing all superfluous material and tidying stuff up. And Ive managed to get the trike down to under 11kg, which I'm very pleased with. My target when I started was 14. http://Lightening http://Front Pick up brackets Macro V2 http://Pick Up Brackets Macro V2, _2 More photos in the Album 1 Quote Link to comment Share on other sites More sharing options...
PatPux Posted September 6, 2018 Share Posted September 6, 2018 (edited) Taxi tested the trike yesterday, and it went well. Nothing fell off! Although I need to beef up the seat support, So, just about ready to fly it. But I need ideas and advice on the line guides that go on the cage. What? and Where? The PAP ones look good but €42 seems a bit steep, so what do people use? Do I recall seeing a large electrical cable tie used , strapped vertically? And Where? At mid height of cage or higher? https://www.facebook.com/100005854994168/posts/900830113455480/ Edited September 6, 2018 by PatPux Quote Link to comment Share on other sites More sharing options...
AndyB Posted September 6, 2018 Share Posted September 6, 2018 Cool. Looking great. Someone earlier on this thread showed cable tie at about halfway point. I was thinking that with my long arms I might be able to just take off as per normal, without and 'assists'. His reply was that that the cable ties help ensure all lines are away from the rear wheels. Good luck, Andy Quote Link to comment Share on other sites More sharing options...
