On the subject of the 160 , i am now running it on Wildcat heli 30%, which works out a fair bit cheaper than modeltechnics Ys 30/30. I add 150ml of oil ( the same type used in the modeltechnics fuel) and it ran absolutely fine. No changes in settings on the engine were needed. You can get 4 gals of the stuff delivered to your door for 86 quid which doesnt work out too bad!
