  1. I am finding that the 12v lead acid battery just isn't enough to start my Simonini Mini 2. Not enough power there. If I connect it with jump leads to my car, it starts instantly. I flew with a friend at the weekend who used a lipo battery pack to jump start it. We made a little connector using xt60 connectors and a couple of leads connected to the battery terminals. We then connected it, started the motor, and immediately disconnected the lipo and left it with our kit on the ground while we flew. This was SO effective I thought I must buy myself a lipo battery and charger. My questi
  2. Anybody know of a supplier for HE R120 spares? I am thinking of buying a used engine but I have been told that spares are very hard to get hold of here in Sweden.
  3. Annoyingly I'm pretty sure it isn't the carb settings as I have tried every setting (spent a very long time over it and turned each screw just 1/8 of a turn at a time) with no difference - it just gets to mid-throttle and then dies. Still, I'll see if the primer bulb makes a difference when it arrives...
  4. Seemed to work for mine, it starts easily now so long as I don't use the decompressor valve that I unnecessarily fitted! It still won't reach full power though. I've ordered a new primer bulb as there are a lot of bubbles in the fuel line and that's the only part I haven't yet replaced. In the meantime I'm flying a Radne Raket motor that I have borrowed from a local pilot. Early morning flight tomorrow...
  5. You have to take out the little allen screw first, then run the drill through the hole behind it to make sure it is clear. Then put the allen screw back in. Weird, but it works. Refer to this: http://www.geocities.ws/peaksclimbing/walldecr.htm The other option is to fit the decompression valve, and yes, mine looks very much like the one you posted a picture of. It was for a Husqvarna 3120XP.
  6. I took the head to a local lawnmower repair shop and they drilled and fitted the decompressor for me. But the easier option is to have a look inside to see if the inbuilt decompressor hole is blocked. All you have to do is use a 4mm drill bit to drill out the carbon and then it should be much easier to start. The big head and tuned exhaust are well worth having if you can fit them. I am 70kg so I get off the ground just fine with the standard solo 210, but it is nice to have the extra power when you launch in nil wind, plus having the ability to climb quickly is great partly just because
  7. Thanks Simon. I assumed the bearings were ok as when I spin the prop without the belt on it spins freely and easily, but there does seem to be some play when wobbling the prop from the tips. It looks like I'll have to try and figure out how to change the bearings then...

  9. I flew my borrowed Fly Products 115 solo 210 motor, which is finally running properly! However, after flying for 5 minutes yesterday evening, the engine suddenly raced to high revs so I immediately cut power and landed. I found that the drive belt (a new one that I fitted yesterday morning) had slipped and become very very loose. I tightened it up again, but as soon as I revved the motor up a little it loosened right off. I tried this several times, but every time the belt would loosen. I'm not sure what I'm doing wrong, or perhaps a part is broken? To adjust the belt I thought I had to l
  10. Thanks, but there are no one-way valves on mine except in the primer bulb, which I have removed for now. But I can't get fuel up to the carb by blowing into the breather hose so perhaps I'll just have to buy a new bulb.
  11. I have been having problems with my Solo 210 with Tillotson carb. It starts and idles beautifully and revs up to about 4000rpm but then dies as I try for full throttle. I think the problem could be the fuel line and maybe primer bulb, so I thought I'd remove the primer bulb so I know that's not the problem. So I replaced the fuel line and filter and took the primer bulb out thinking that I could prime it by blowing into the breather tube. But as hard as I blow I can't get any fuel to even start going up the fuel line let alone get it up to the carb. Does anybody know if I can get around thi
  12. ... And yes, I'd definitely agree with starting out on a reverse-launch day, it is a nice easy way to start. Get the wing up and settled, then it's just full throttle and go. Enjoy!
  13. I flew it for the first time a couple of weeks ago, but when i landed to check the plug (to see if it was running rich/lean) the starter mechanism broke! I have ordered new parts but they haven't arrived yet, so i have fixed it as best i can so it starts. Going for a flight this evening. Will post a video if i can...
