nitro to FE

[Francisco Liantaud]

hello all,

I was into nitro mono years ago and I just ordered a 4092 1730kv for a 37" areomarine with 180 amp esc for 6s and was wondering if anyone can give me a starting point for a prop.
I am thinking x448 octura I was running x452 with OPS 7.5.

What is your goal, sport running, fast straight runs or 6 hard laps for racing? I have run that motor in a mono and it pulls 200-250 amps with anything over a 545 prop. With only a 180 ESC I would use a CNC 44mm Alum 3 blade to start. About $25 here on OSE. Watch temps like a hawk and go up or down from there. Bear in mind your 7.5 rpm's were probably 20-23K and the TP will spin up in the 27-30K range under load.

thanks for the reply. I went down to 1390. I'm just farting around a x450 to x452 prop with 6s. Maybe I'll try some club racing down here in Miami in tha near future. I also have a challenger 43 that I think of converting in soon maybe 12s. any recomendations?
