Bob Moore Posted June 2, 2017 Share Posted June 2, 2017 You may have seen my long and tortuous thread about trying to get a Solo 210 I acquired to run properly, or more accurately restart after it had been run. (It had sat in someone's garage for 20 years) After wasting £200 on it I finally gave up. Bought an Adventure F3 that needed a starter motor and my old one fitted, had a few other little things to sort, engine mounts, fuel lines etc. but that paramotor starts, restarts and runs well. 48 inch prop. I also acquired another motor, a more recent Solo 210 unit with CDI ignition for free and have transplanted it into my original machine which had a 4 bladed 36 inch prop, lighter weight, smaller cage . Lo and behold I started it today, hand start, but only briefly as it has no prop on it at the moment. So here's the issue. The old motor has a mount with 6 screws for the 4 blade 36 inch prop. The motor I acquired for free has a boss with 4 bolts. It's looks like a hard job to switch the bosses (I'd need to switch both) so I hope to drill out 4 holes in the wooden boss to fit the new boss. I realise this is a risky procedure balance wise. Don't want to shell out lots of bucks as this motor hadn't been run for 8 years and as it was I spent £200+ trying to get the original working. Does anyone know a safe and reliable way to re-drill a prop for a different mount please. I just looked at some prop specialist web sites and it would cost more than this thing is worth to get them to do it. Quote Link to comment Share on other sites More sharing options...
admin (Simon W) Posted June 2, 2017 Share Posted June 2, 2017 Get a bar that fit's tightly through the middle of both props (6 hole on the bottom) and then turn the top one (the 4 hole one) until you can see some meat to drill into. This is not something I have done, but have seen done. ( I think a couple of them get quite close in terms of holes so be careful ) SW Quote Link to comment Share on other sites More sharing options...
Bob Moore Posted June 2, 2017 Author Share Posted June 2, 2017 Thanks Simon, I have provisionally marked it out and it is close to some holes, but that said it's clamped by a big plate on the outside and I'm confident it won't weaken the hub. I was given some other 45 inch props that have been re-drilled though haven't tested them to see how successful it was. (Too big for this cage though.) Most important I feel is to find a workshop with a good solid bench drill so that as well as being properly positioned that they are vertical! I can see a potential for all kinds of problems if they are even just a degree or two off! 1 Quote Link to comment Share on other sites More sharing options...
admin (Simon W) Posted June 3, 2017 Share Posted June 3, 2017 Many moons ago on the tip to tip we got 6 'TP propellors' from the for our macros. 2 of them were ok. The other 4 had the mounting holed drilled slightly off Center. The mad thing is, they he still ballenced them!!!!
