In discussion with a chap called Allan Ballard at Ladbroke Hobbies in Warickshire about sourcing another 50cc AeroWorks kit (more about that later), he suggested considering a Kolm 4 stroke petrol engine for my next project. This is a new one on me but I understand they are made in Austria. As there are no prices on the website I guess they are firstly very expensive and secondly for the very serious flyer. I am just curious as a confirmed OS lover. That said Allan was quite disparaging about OS petrols, too much vibration apparently, but I suppose he would say that. That put me in my place!

To go off at a slight tangent here, the reason I ended up speaking to Ladbroke is that after contacting AeroWorks in the Denver, US about trying to source their ARTFs in the UK now that IAD Model Designs supply has almost dried up, they suggested Ladbroke Hobbies. That drew a blank sadly and part of the supply problem is due to shipping costs from the US. Unless somebody is prepared to stump us £20k for a crate of them to import the AeroWorks kits it is not economically viable. crying

Anyway, the long and the short of the discussion with Allan was the purchase of a Pilot RC Extra 300SC 88" jobbie smile p. It's supposed to be with me by Thursday , shipped directly to me from Macgregor Industries apparently. Hope I have done the right thing…………..

Of course if you really want to spend some money Kolm do a very nice 4 in line.

And it makes a nice noise too!

Very nice sound, but why on earth is it compulsory for German modellers to have their throttle "on a switch" except when landing. I personally would like to have heard a varied throttle sound. Galloping around at full throttle all the time does not do this motor justice.

Wouldn't pass the 82dB guidelines would it? Blooming awful landing too. Nice noise though!
