Prop size?

Dont get to confused Simon, if you go by your watt meter results from the stock set up, as a guide for your new prop/power output you wont go far wrong, my Dynam Fw190 on stock set up she flies with more than enough power, so as long as you are around those numbers you should be good to go.

I fly mine at around half to three quarter throttle for a more scale like flight, I did send a Email to Ecalc about their results with this motor but have not heard back from them yet. I would ignore the recommended prop sizes in the motor spec sheets, they seem to me to be simply wrong, if they were the correct specs there would be an awfully large number of posts about burnt out motors etc from Dynam fliers as this motor is fitted to quite a few of their models.

As you fly from grass you might consider removing the landing gear doors (couple of screws) they can cause a nose over all on their own, no mater how good the landing (mine spun around on the oleo leg and pressed up against the back of the wheels ..... just like a brake!!!)

I am going to test fly mine tomorrow, as I have faffed about with it long enough now.

15x6 APC 2 bladed prop.

4s 2800

Take off from our small tarmac circle

Land gear up on the grass, hopefully without breaking prop.

Record flight time and battery capacity etc.

If all goes to plan.....................pub!
