Im no wizard about elect. stuff. but I have some experience, and all that equipment sounds like a serious overkill. The airplane you have is a little hacker and designed for an .049. a 1450kv and 30A esc and 74 prop os what Im running on an f2d 48" wingspan.

Would this setup power a sig Akromaster?

From my experience thats the wrong motor. This is the setup I run on my Clown, my Flite Streak, and my slow combat model. http://brodak.com/electric-power-pac...ude-plane.html It will pull a larger prop. I'm running a 9/7 and sometimes a 9/8 on it. Your motor will require a much smaller prop that would be too small for that larger aircraft. Your set up is about right for a super light, fast model that will run the battery down in short order. I havent even flown my F2D yet, but I'm expecting it to run about 2 minutes at about 80 mph on a 7/4 prop. And I will use a 50 amp ESC. I dont have any pics of it, but I'll try to get some soon for you.

The package that I'm running on a similar sized 1/2A combat wing is the a 2212 - 2200 kV motor, 2 cell 1000 mah Lipo, 20 amp ESC, and a Hubin timer. This setup turns a 6-6 prop at about 15000 rpm and flies the plane easily on 35 or 42 foot lines, though it wouldn't be too competitive with even a TD powered Hacker. It's more of a sport flyer or test sled.

That motor is slightly larger than your 1408-1450 and the 1450 wouldn't do well on 2 cells, either. I would go with your 1408, 3 cell 850 or 1000 mah Lipo, your 30 ESC (which will work fine and doesn't weigh much more than a 20 amp one), probably a 7-6 prop. Expect about 12000 rpm and 10 or 12 amp draw, which would work out to about a 4 minute flight on the 1000's. You will also need some type of control line timer - I really like the Hubin's with screwdriver adjustments. I don't know for sure, but I seem to remember that the e-flites need to be reprogrammed every flight at least for flight time. The Hubin timers should be available through Brodak.


The nice thing about electrics is that they are very versatile and you can generally dial in just about any motor/prop/battery combo to at least be flyable.

I thank you much for your response, and will add this info to my list.Just trying to get enough to try a setup on a control line.
thanks again.

The motor, ESC, and battery will have significant weight. Then, there is a problem of how to achieve throttle control.
I'd guess that the usual 2cy glow engine would be more successful with less hassle. The motor you mention should be more than needed.
It specs at 160W. max.

The timer provides the 'throttle' control. I don't know which motor you are referring to, but 160 watts is about where a 1/2A combat plane would be
happy. The motor that I mentioned is running on two cells at about 15 amps, so roughly 115-125 watts. Yes the motor/battery/esc/timer weighs
more than a glow motor but the thread is not about which power plant is preferred, but what electric setups would be would be adequate.

Can you recomend a inexpensive battery and charger for this motor and esc?

the IMAX B6 Charger/Discharger is a very good one for the price http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5548&gclid=COj5pIbn0bsCFYtQOgodvy0AFQ


this battery would probably work http://hobbyking.com/hobbyking/store...Lipo_Pack.html

Interesting info, Mike, I gather that this electric motor with setup as you describe with a 7x6 prop turning about 12,000 RPM puts it in the same power range as an Enya .09-III. I'm using that Enya power setup on a 30" span Japanese OK Models Pilot Cessna 177 Cardinal semi-scale. I've also found the Enya .09-III TV with 7x6 prop to provide very spritely performance on the larger 1/2-A RC model, definitely a welcomed step up from the Cox reed valves.

AFAIK, that electric setup you describe seems to be about what I need to power my Sterling 36" span P-38 Lightning profile CL. I don't have preferable glow motors lightweight enough to power that. It was designed in the 1950's for the available motors then, .09 to .19's. The newer .09 Schneurles definitely would smoke these lighter weight older non-muffled engines like the .15 Fox (not .15-X), OK Cubs, earlier Duromatics McCoys, etc.

As an electric on 7x6 or say 8x4 props would be more profitable as one could use one timer to control 2 ESC's. Both motors come on at the same time and quit the same time. The wing is thick enough I think one could hide the batteries for each inside compartments in the wing.
