May 07, 2009 by jez | Posted in Hobbies & Crafts
Iv just built my first heli from scratch a HKH 450 Trex clone and have fitted it with a 30Amp ESC and a Mystery D2825-5000rpm brush-less motor...
So now its built I'm looking for a powerful Li-poly batteries but not quite understanding the 10c 15c 20c and so on rating of the packs
I would like a battery to give at least a 10min flight time if possible

Trex 600 Electric Helicopter Advice?
Sep 08, 2007 by Hopeless | Posted in Hobbies & Crafts
I recently purchased what I believe to be the nemesis of my life, (other than my mother-in-law). So, therefore, I am going to need a lot of 600mm WOODEN blades (hopefully it will not get much worse than this). I am also desperately looking for a training gear set-up for this non-micro heli. All I can find is for the Trex 450 size. But I am not sure it will work for a 50 size chopper. I have looked everywhere. Can you steer me in right direction?
(I'll even throw in my wife as a bonus if you can help)
try here they have them

PS you can keep the wife Two would be one to many
fly safe

rc helicopters?
Jun 25, 2008 by Grant Y | Posted in Hobbies & Crafts
hi my name is grant and i am wanting to get in to rc helicopters after 5 years of thinking about it. first of all i have no idea what kind of rc helicopter i should get for my first heli and second of all i am wanting an electric one because the gas used in the nitro ones are expensive and i hate mixing gas. i am also looking for a big one the size of the trex 450 or walkera dragonfly 60 and with it i prefer a 6 or more chanel transmitter or remote. i also need to know where the closest rc helicopter place near tillsonburg ontario is and how much they are and if anyone has any good sites i should learn or get advice from i will look in to them. I have $550 to spent. your answers will be highly appreciated. thank you.
Dude, helicopters are hard to fly! If you are not experienced I would get the E-Flite Blade CX2 http://www.hobbyzone.com/rc_helicopters_e-flite_blade_cx_2.htm
It's easy to fly, easy to repair and a lot of fun. Once you have mastered that then move up to a single rotor with an anti torque. E-Flite has a pretty good selection of electric heli's.
You might want to get a RC flight sim. When you crash there you won't cry and it's a lot less expensive.

Electric and Nitro helicopters?
Jan 10, 2009 by kevin30jt | Posted in Hobbies & Crafts
What is the difference between nitro and electric helicoptors, and what is the differenc in all the trex models like 250 450 500 600 700
To correct both of the people before me:
Electric helicopters run primarily on Lithium polymer (Lipo) or Lithium nanophosphate (A123) batteries nowadays, not nickel-metal hydrides. NiMH is too heavy to use in pretty much all helicopter applications as their energy density is too low and they are too heavy. Lithium Ion batteries are not very well suited for helicopters either as they use are slightly lower voltage and energy density than Lipo batteries and they come in hard cases which is a weight penalty.
Nitro helicopters use a two-stroke motor than runs on a nitro/alcohol/oil mixture that is ignited by a glow-plug. Typically, nitro engines run for much longer periods of time than their electric counterparts, but E-helis have much more power than the nitros. Brushless motors and the high energy density Lipo batteries give electrics a big advantage over the nitros because they have instant torque and Hp. Both will perform about the same overall though, so it really comes down to preference.
The sizes refer exactly to that. The bigger the number, the bigger the helicopter. A 250 will pretty much fit in your hand and is about the length of your forearm. The 700 weighs upwards of 10-12lbs and is about 4-5 feet long with full blade extension. typically the sizs are based on the length of the blades or the motor size, but there is a bit of confusion even for heli guys in the middle ranks. The 450's use 325mm blades, the 500 uses 430mm, but the 600 and 700 use 600mm and 700mm blades respectfully.
Nitros on the other hand, typically go by their motor size in cubic inches. A .30 cubic-inch engine is called a 30 size. A .50 is a fifty size, .60-.90 is a 60 through 90 size etc...
Sometimes they combine the two and just use the designation (N) or (E) to represent their specific power source. E.G.-Trex600E, Trex 600N, Trex700N, etc...So far, Align is the only company that really uses the hybrid system, but some people are referring to the sizes and using the E or N designators anyways.
It's a bit confusing at first, but you get the picture after you've been around them for a while. Hope that helps!
