I'm considering buying a Mini-Mag kit. It comes with a brushed motor.
Does anyone know if my 7.4 lipo would be enough power for it.
It's a none discript i.e. no name battery that came on a park flyer.
I don't know the c rating but it is 1800 mah
I had a Mag, and as I recall, I used a Warp4, 4 turn or 5 turn with a two cell-if flew rather well. As to the brushed motor, it's a 6 volt one as I recall and so it should be more than enough! The problem as I see it is that the brushed motor is very, very marginal with this airframe.
Anyway, it's a wonderful airplane so have fun but be sure to make it with MAXIMUM elevator throw for better landings!
My unqualified answer is "YES!" The mini flies like a dream with a brushless power system. I recommend a 3s 2100 mah lipo and an inrunner of some kind-as I recall, my "best" power system included a 5 turn, Warp4 (now gone?). Using an inrunner avoids all the problems of modifying the airframe to take an outrunner-be sure it's a "drop in" speed 400 replacement, and many are available.
The mini is a wonderful airplane.
By the way, if you have not built it yet, ignore the Teutonic instructions which state that in assembling the fuse you put ca on one side and accelerator on the other! Maybe Germans can move that fast but I couldn't!
It would be worth your while to talk to David Skokan at www.lightflightrc.com - he has several 28mm inrunners which could be used with 2s - if we assume your pack can manage 15-18A (10C 2s 1800) then a 28-37-4 might be good, or a 28-47-3 (both of those might spin something like a 9x4.5 on 2s at ~17A).
Thanx Dr Kiwi and Dave. I'm really going to have to bite the bullet and invest in a couple of 3s as My 2s won't hover my NASTY. But I still need to find a use for my 2s, thats why the question. I need a plane to train my grandsons next year and the MiniMag really looks good.
Pity you have to live in such a beautiful place! Say, that new President is a pistol!
Well, I highly recommend the HobbyCity/United Hobby 9 gram servos, and I fly them in some rather expensive planes-just be sure to get servo extensions because the Mini will need them.
The Mini is a wonderful airplane!
I recommend a Warp4, 6 turn INRUNNER, which is apparently out of production but still around. Try nesail.com, which I think has them for $30, or basicially free to someone using Euros! (thanks, Bush, for all your help!)
I used a Warp4, 6 turn because it required NO modification of the mount (it's a speed 400 "drop in"), and it gave me great thrust and efficiency-I think I used an 8/6 apc slo fly prop and 3s, 2100 lipo, with a castle creations 25 amp esc. But, Hobby City has some very nice esc's for almost nothing-get the little usb programing device.
Have you assembled the Mag, yet? If not, ignore the Teutonic instructions which provide for CA on one side of the fuse and accelerator on the other, UNLESS you are faster than corn through a goose! (you know, the foie gras thing).
You picked a great flyer and be SURE to have full elevator (pitch) control available because it makes the landings less embarassing!

(P.S.: I didn't realize the dollar had an value. Well, I hope your Fearless Leader is better than ours!)
(Second P.S.: I found the Mag flew better with more than 150 watts at the prop-the Himodel "looks" to be less, so I move up, and, again, an inrunner of the right size just "drops in!")
I'm gonna mail the guy at nesail.com about the Warp4. But do you think it's a best buy and better than the Himodel ? I don't really care about doing modifications in fact, just wanna get HUGE amount of power on this plane.
Which ESC would you buy if you were me (url? cause there's so much stuff in hobbycity!!) ? I wish I could buy everything from the same shop. That's why I posted the Himodel urls ...!
Which servo too, it seems the 9g are out of stock (again url? cause there's so much stuff in hobbycity!!)
But maybe I could get the warp from nesail and the esc + servos @ hobbycity - ?
The Warp4, 6 turn is capable of more than 200 watts! I have one just waiting for a new home! As for huge, try lightflightrc.com (california)-they will gladly design a power system for your specifications!
Since you are spending real money, why not go for "the best."
As for servos, try servocity.com for the Hitecs.
NEVER "backorder" from HobbyCity.
Take my word for it, 200 watts on the Mini Mag will (1) allow you to keep a 35 hour work week, (2) go vertical, and (3) fly any rational maneuver.
For more alternatives, and I hate to send you there, go to rcgroups.com and search for "mini mag." There are many, many inrunner and outrunner systems already proven for you! But, as far as I'm concerned, you best cross yourself before going! (look for the sign "666" as you enter!)
If you have any further questions, feel free to send e mail to email@example.com to avoid this interface.
Man, that guy had a good-looking wife-what was that all about?
http://www.nesail.com/detail.php?productID=3405 for Warp Specs! That esc is o.k. and will work-I suggest a Castle Creations Thunderbird 18 or 36, or Phoenix 25 or 35-these are programmable (the easy way, with a cord) and outstanding products. If you need a "best price" source for cc, let me know.
If you need help getting the Warp 4, let me know-I'll be glad to help, but I suspect Northeast sailplanes exports, too! I have one of their Viking models-man, what a ship!
