Default RE: Extreme Flight RC Yak 54 - 74 inch!

I would think the Saito 1.25 would be the minimum engine choice for the 74" model. You might need to really work at balance with it being a full lb lighter than a 1.60 (including mufflers)

Still, with some effort and light building... perhaps you could beat the low weight in the suggested range... and maybe come in at 10 lbs? Until people get some (hopefully end of August) it's mostly conjecture as to weigh and balance.


I suspect that the 1.20 would be like the 1.00 was on the 68" Enough to hover with a little pull out... and a few mods to balance (like placing the battery on a "tounge" that sticks out over the engine. It would be an extremely light build... Run 30% to get maximum power from it... and a person might emjoy it quite well...


Still, if you haven't purchased a motor yet... the O.S. 1.60FX or Saito 1.80 are going to provide the 3D power most will require...
