Hi!
Tank set up is as always important!
For a .45-.47 engine use a 8-10oz tank! Not bigger! Prefearably set up with uni-flow system (Two clunks) and at correct height!
Nitro in fuel is important but 15 or 20% is just overkill on mot engines. 20% nitro could even be too much for some.5% is just fine!
Prop: 12x4 APC or RAM. 13,25x3,75 APC could also work.
Glow plug : OS 8 or Enya 3...but there are lot's of others that also work good. Avoid old-style plugs with idle bar!
