Now Now littlecrankshaf, where do you see a "flatfootedly" claim? What you see is a direct quote from the manufacturers. I don't claim the ST3000 is 3hp, Super Tiger via Tower Hobbies makes that claim. I don't claim the Moki 180 makes 4hp, Moki via Horizon Hobby makes that claim. If you even read the poll description you'll see I don't even use 25% in it, rather I simply ask people if they thought the Moki makes significantly more power than the ST3000.
BTW, 3 hp divided by 4.1 hp is .73. Subtract that from 1.0 and you get ~27, therefore, the Moki 180 is not 25% more powerful than the ST3000, it is 27% more powerful. Now, which manufacturer is inflating there products? Is Moki inflating the 180 or is Super Tiger deflating the ST3000?
In any case, I accept the challenge and will put both of these engines and the OS FX 1.60 on my PSP test stand in the next couple of months. We'll find out then which engine spins a prop better under the same conditions. (Of course this is not a real test because it doesn't test torque. You can only measure that with a spring-like device attached to the test stand -- don't have one.) It is my intention to adjust each engine for maximum rpm and back off 300 to prevent lean running. I will use the recommended fuel for each, i.e., Byrons ST Fuel for the ST3000 (have 2 gallons of that), Wildcat Extra Premium 15% for the OS FX 1.60, and Omega 5% for the Moki 190. What do you think I should use as a prop for this test -- thinking on using a 20x6 Zinger? That should be a good test for all three engines and will probably be the prop I'll end up with on my Moki on the 1/4-scale Cap.
