TSK BlackStar GS2 engine failure
I have one of these machines with a Tanaka 32cc petrol engine.
Unfortunately I need to repair/replace one half of the crankcase as the carb mounting has fractured and broken off.

I have tried to repair it with some specialist chemical welding resin but when I ran the motor the heat softened the resin and it failed again.

I may see if I can get it welded but I know this may be a problem.

Does anyone have one of these motors kicking about from a broken heli or maybe an idea where to but the spare part from.

I have e-mailed a couple of UK dealers for these engines but as today is Easter sunday and tomorrow is a holiday I probably won't get an answer for a few days.

Any help with resolving this problem will be much appreciated as I have no intention of retiring this heli.
Thanks
Why fly the rest when you can fly the best. What are the best these days anyway ?

Repair
As a Marine Engineer we use quite a few materials for repairing castings and some that are used to actually replace missing bits (I have replace a missing half from a glow engine carb mounting). Once this material dries out then it is nearly as strong as aluminium itself and can be machined and even tapped to take bolt threads. If you get no luck with replacing the one you have then I may be able to effect a repair on your broken bits.

Hi Joe,
many thanks for the offer. I will let you know if I can't get it sorted.

Modtron, Thanks for the thought.

Andy and I are TSK UK.
Andy did sales and I did/do parts.

i will assume you mean the tanaka 23cc as used buy hirobo
ripmax list a complete engine
and the only engine spare they list is a pull start assemble

the other option is to find whatever garden equipement use the engine as see if the case is the same (and it will be miles cheaper than ripmax)

Unfortunately it's not 23cc. It is 32cc. The 23cc is the same as the one fitted in the MyStar 60. I have one of those as well.
I think the motor is a Tanaka EC-330 from a chain saw but is modified for use in the heli.

Graeme,

Tanaka is a small gasoline engine manufacturer who also supplies the same engines to a number of weed wacker manufacturing companies.

Check for local small engine repair shops. Some are familiar with the brand and they have sources for parts.

My MyStar GS uses the Tanaka 24 and I found parts available for it from such a shop here in Canada. He has since moved, and I fly my Century Predator gasser most weekends now (uses the G231), so I have not followed through on where he has moved.

But I am sure there must be similar sources in the UK.

Hi Phil,
I have spoken to a guy we use at work for specialist welding.
I am going to see him on Thursday with the broken crankcase. He seems to think welding it back together again would be possible.
Thanks for the reply.

Quick Update, I had the engine crankcase welded up last week. Bit of a mess afterwards but I spent a couple of hours in friends work shop yesterday morning milling the crankcase back into shape. Put the engine back together and back in the heli last night. I finally flew it today. It needs a little work on the heli setup and maybe a little tuning to sort the high and low needles properly but at least it flies.
First air under the rotors for at least 8 years.

After a couple of confidence flights it will be going back in the Vario big Jet Ranger fus.

Strange at the field today though.

We fly under the Heathrow approach although 10 to 15 miles out. Wierd with no commercial activity.
