G'day

I can't tell you anything specific about the 65 apart from the fact that I have three, I use a 13 x 6 prop usually, I use fuel with 10% nitro, 5% castor, 15% synthetic and the rest methanol. The 65 is an older design and is quite heavy as it has a brass liner which is chromed. They are very docile engines and were very popular with scale model builders for their ease of use and good power for their size. I bought my first one for an ARF Sig Kadet Senior. I chose the 65 because I knew it was on the heavy side and as a result it balanced the model perfectly without any additional weight being needed. I have since bought a second hand one which looks like it has always run on castor based fuel and as a result it is a bit coked up but runs fine. My third is new in its box still waiting for an outing. Nice reliable if slightly heavy engines. Heavy compared to more recent Saitos, not when compared to OS Surpass engines.
