I bought a MVVS 21 GFS/R ABC RC a year ago and despite many attempts i am going to give up to use it.
I have to recognize it starts very well and i had never difficulties to do it. But when the engine start to warm up it finally goes down.
I tried any tuning that i can without success. I use the standard glow, a 5% nitro with 18% oil including castor oil. The mufler us the default one, no pipe.
Any help or advice how to start again the tuning and how to manage a step by step tuning will be helpful.
I also have OS, ST and saito engines that run fine.
Thanks.
Pierre.

The problem probably is in the fuel.
Run it with FAI fuel 80 methanol, 20 castor, no nitro. These engines dislike synthetic oil and nitro in the fuel.
Open the idle needle 1.5 turns, as well as the main needle, and fit a 9x4 prop. Enya 3, OS8, Novarossi 5 plugs are excellent.
