Yeah, but the OEM ESC is worth negative $20 to half the people (its just a PITA unless you're lucky!) and those servos wholesale for $0.80 each so we're not talking a big difference. I think a lot of people would take comfort in the fact that it comes without electronics!

If I can get the planes for A LOT cheaper, then I'd look at it. Or if I can get the 60 shipped over for $500 or less I might look at that.

Anyway, pass on the details and I'll check it out.
I will send PM.

Yeah, I agree, but it would explain why the LowPriceRC.com planes are being sold much cheaper.

i'll start with this in mind.., second is the exact position that the motors have to be mount into the wings..

I think the diagram is correct , also make sure to get a set of contrarotating propellers since the correct way of doing twin engines is having both propellers spining the other way fo the other so any prop torque is eliminated.

For what i saw just behind the engine in the wing bellow or over is the better place to put the ESC since that way its getting refrigerated directly by the fresh air moved by the propeller.. but i think all twins use this (like the twinstar) and just make sure the battery
can take the AMP load of 2X engine (i dont think it should a problem, even the cheap lipo zippis 3S 2200 are rated at 20/30C meaning they can take 44A constantly and 66A peaks , 2 CF engines at WOT should be pulling 40A and no one flies WOT constantly..


And at least for Dave Powers said in the twin engine Hawk Sky video , it wont it make it much more faster.. but have greater thrust and aceleration and climbing capacities

Are counter rotating props essential? It seems to me that in real aircraft it's a nice to have but not essential. If the props are not counter rotating they make sure that there is sufficient rudder authority to counter the effects of the critical engine. Which to me is not an issue we need to deal with flying model aircraft the way we do.

But since Hobby King sucks (sorry, I've had yet another problem with defective merchandise today) just get the shell from lowpricerc and put the parts in yourself.

I had to replace all the stock servos, ESC, and motor in my CF and will probably buy the CF shell as you suggest.

EasyStars are now available too. Cost around $70 LHS. Would need ailerons to be cut.

BTW some of HK stuff is excellent IMO. The HXT900 servos work great and are cheap, a high power inrunner is less than $20, a 40amp heli ESC gives rocket performance.

If they work. And if they don't, you're on the hook for their poor quality assurance. I'm just saying...
