E-flite Sea Fury

i am really attracted to the sea fury.concernd abit about the  number of servos i will need to run off the esc. lots of servos = big esc = big cost.

 

You could keep it a 3 servo set up and hand launch/belly land. But I must admit it's nice having the retracts and rudder operational. 

 

 After much recent head-scratching, I've finally maidened it this evening. This one has a Giantcod SP 2217-9T 950Kv, Jeti Advance 30a ESC with a separate 3a UBEC (as I'm running 6 servos) and  a 3S1P 2200mah 20C Li-Po. Although the published weight range is 710-850g, mine has ended up at 880g with 44g of lead in the nose. I've got the ESC and UBEC well forward so perhaps the 9g servos may have made a difference?

 

On the Wattmeter, the standard 10 x 8 prop showed 169.3 Wp, 15.19Ap and 10.86Vm.

I haven't tried any other props as yet - to use the spinner with my motor, which has a 3mm shaft, I need thin props and I'm a bit short of them at present out here. 

 

There have been some comments about the plastic underwing covers not fitting well. I trimmed the velcro pads for a better fit, CA'd them in (not together!) and, after rubbing down the moulding nibs, I painted the inset part of the wing surface and servo wells with Aeropoxy. This has given a much better surface for the double-sided tape to adhere to and the preparation seems to have paid off. I still needed a few spots of CA along the leading edge of the panels, though.

 

So to the flight. Well, I have to say that this was my first flight with a low-winger since 1982-3, so there were sweaty palms! Having taken a few pics for posterity and being on my jack out here at present, I set up the camcorder to make some sort of record.

 

I wasn't expecting much from the video and I was not disappointed! To be honest, once I'd taken off I forgot all about it. Anyway, being totally shameless, I thought I might share it with you. It has to be one of the least useful attachments ever placed on this forum but it records the survival of the model to fly another day! It's just as well I have a sense of humour - and you'll need one, too! That's the trouble when you've learnt how to use things like Youtube - you just have to keep using it, don't you?

 

 

 

Anyway, thoughts on the flight. Trimming-wise, I made no adjustments as it seemed about right. The motor was much noisier than those in my other models - could this be prop noise? I must say it sounds a bit of a brute - just like the full size!

 

There seemed to be a lack of thrust although it climbed well enough - could anyone suggest a better prop size for my power setup? I do seem to have a few amps in hand but I'm not looking for speed.
