XRP 14 Blade fan and Dr Mad
I have trolled the forums and struggling to get a little info.
I have installed a Dr Mad 29mm inrunner 3000kv in a new 14 Blade XRP fan.
I have connected a turnigy delux 100amp esc and will be testing it today.
I will be testing this purely on 4s
The questions I have are as follows.
1 Any idea on the timing requirements for this setup(based on actual tests)
2 What amps can I expect?
3 looking to get around the 1200 watt range
4 Hopefully will get around 1.5KG thrust
This will be installed in a HK Sportsjet.
Thanks in advance

1. You should use low timing.
2. 70-80amps depending on your batteries
3. About 1100-1200watts
4. I get about 1.7kg on a test stand but in the airframe you will get much less, probably 1.3-1.5.

I would like at least 1000 watts, as I have many setups I can get that with but the sportjet is restricted space wise for lipo's.
Am contemplating actually cutting the top to have a standard access instead of the cage from the bottom, I can reinforce it with cloth and resin.
ideally like to use my 3300 4s1p nano techs rated at 45-90c
The other thing I don't particulary like about this fan is the collet type adaptor, it seems as tight as I can get it but hesistant to use threadlock until I have tested so I can remove it if it crap performance.
I have a cs480-2500kv which would keep the amps down of cos but this I think is too low a KV for what I require.
I also have a HK l2855-2100kv which is supposed to be good on 6s1p, but too heavy for this model.
thanks for the timing info will adjust as you mention
