RE: Dragonfly tail motor
I ran a brushless for a while with excellent results, both geared and direct drive. The new short feigao 12mm brushless looks perfect for using geared on the tail with minimal weight gain over the N20 motors. After i got the T-rex, i see no tail motors in my future, ever again. Dylan

RE: Dragonfly tail motor
The stock N20 motor is a 7.2 volt with carbon brushes, the motors from allelectronics are a 3 volt with wiper brushes. they are not the same and will not work the same, the dual motor option was thought up as a way to use the cheap low voltage motors. try the 3 volt on its own,and it wont last long.

RE: what size heli
Compare parts prices and the T rex wins, compare manufacture support and the T rex wins, compare flight ability out of the box and the T rex wins, compare price and the rex wins, compare crash survivability and the rex wins. The T-rex is basically a scaled down copy of one of the most succesful helis ever made~ the Raptor. the T rex comes with 3 sets of blades too, for $40 less than the shogun. Should be an easy descision, unless your looking for all out mad dog 3D performance, the zoom will do better because its lighter. the Rex wins across the rest of the board. the zoom/shogun comes preassembled, when you crash you have to figure out how to get it apart to replace parts, you put the rex together, and its an easy and fun build.

RE: Dragonfly tail motor
you can use the low voltage N20s, as long as you use two of them and wire them in series with each other, www.like90.com and www.helihobby.com both sell dual tail motor kits for this purpose. GWS makes a tail shaft/prop replacement kit that uses a 6x5 GWS prop as a tail rotor http://www.allerc.com/product_info.php?cPath=24_64&products_id=1209 Most of us just use the IPS motor direct drive, you lose a bit of flight time, have to re-balance the heli, but its an easy mod and easy to find parts, plus gets rid of the gears on the tail.

RE: Hacker Brushless pinion problem
Use green loctite #638 i get mine from www.azarr.com $1 for 3 little tubes. clean the motor shaft and inside the pinion, smear some loctite on both and push the pinion on, making sure its in the right position, and let it dry for a few hours. the 638 loctite is for retaining rotating parts, the red and blue might work, but they are more for locking bolts in place. if you need to get the pinion back off, heat it up with a lighter and gently pull it off with a pair of pliers. This is the correct way to install a slip fit pinion. Also loctite is anerobic, meaning it only cures in absense of oxygen, so any loctite left outside the gap will not cure, this is normal and doesnt mean the loctite hasnt cured yet. Dylan

RE: Shaking Micro Heli.
put your piccolo blades on the dragonfly, youll be amazed how much better it flies. About the violent shaking, i run my blades really tight, and align them by eye before i spool up, ive found that in forward flight and fast forward flight if the blades are too loose they will come out of alignment when making turns, and the heli shakes violently and ends up crashing. they should be tight enough so that when you hold the heli on its side and shake it the blades dont move. You usually have to use a different(longer) bolt and locknut thru the head to accomplish this. Dylan

RE: U-Can-Do 3d 46?
I would bet that the .51 and the 10x6 prop is the culprit. try an 11x4, 12x4 or 12.25x3.75 prop, that 10x6 at 12000rpm is producing about a 70 mph pitch speed, where most of the people flying this plane are using a 4 inch pitch prop maxed around 10000 rpm, which gives you around a 40 mph pitch speed. If your elevator linkages arent perfectly slop free, and your servos are sloppy around center, maybe combined with a non sealed hinge gap and no reinforcements, anything over 35-40mph would probably introduce flutter, and rip the elevator off. by changing to a bigger, lower pitched prop you gain alot of thrust and lose the speed~which this plane was designed for. Half throttle may be producing a higher speed than you think with that 10x6. Dylan [quote]ORIGINAL: hobby_man I have had two Horizontal stab's break off on this u can do 46. The first flight broke it off at 1/2 and the second flight at 1/4 throttle broke it off. the plane has a super tiger 51 ringed and a 10-6 prop I have 20 years in this hobby and I cant figure out what is wron. see picture Any ideas????

RE: Re: Help: Prop set up for hacker B20 12L
the 12L motor is wayy too hot for 3S lipo and an 11 inch prop. Invest in a whattmeter, and ill bet you find out that a 9x6 prop is probably the largest you want to run to stay under 20 amps. The 18L would have been the better choice to run an 11 inch prop on 3S lipoly, and thats even pushing the amp limit on these motors given they are all running with the 4:1 maxon gearbox. 5 minutes out of a 2000 MAh lipo pack is going to kill the pack in short order, too many amps. an 11x4.7 prop with your current setup is going to heat your motor up, and demagnetize it. Dont use GWS props on brushless motors this powerful, they have very poor performance at higher RPM's and there is a possibility of it throwing a blade in flight~which could be dangerous. $60 for a whattmeter is worth it, considering you have 300+ in equipment your trying to kill.

You can expect more power AND longer flights with this upgrade. http://www.b-p-p.com/BrushlessMotors.htm#mega Also, check out rcgroups.com they are more electric oriented, and you could find threads on brushless zagis all day long for ideas.

RE: Jumping Jack 3d motor choice?????
ill second the Lehner 1020 Awesome power, and nothing gets too hot. I have the 1020/17 in a GWS eps400 gearbox, much more robust gearbox than the 300 series. it spins a 13x6.5 apcE at 6500 rpm, 22 amps on an Irate 3S 2200 pack, 3 lbs of thrust up to 23 minutes flight time, 3 lbs of thrust on a 19 ounce plane is insane, i would estimate 30 mph straight up, maybe faster. I have enough power that i can set the plane on the runway, give it a burst of WOT, chop the throttle and pull up about 15 feet, without the power on<~~crowd pleaser for sure. i have about 150 flights on the original gearbox and gears, and they dont show signs of wear, hardest part is drilling the pinion gear out for the lehners 1/8 inch shaft, which isnt really that hard anyway, be sure to use green loctite, and have the correct gear lash. you could get 3 lbs of thrust out of a hacker B20L, but not with the maxon gearbox, and not without demagging the motor from the heat. The Lehner 1020 series motor fill a gap between the Hacker B20 and B40 models~perfect for this size of airplane(40" 19-25 oz) Also, the 1020 weighs 2 ounces i think the hacker weighs about the same, but handles 100 less watts of power.

RE: Importance of Brushless ESC for a Brushless motor
brushless motors will not work without a brushless ESC . <~~~PERIOD Brushless motors are 3 phase, they have 3 wires coming out of the back of the motor, these 3 wires are energized in a sequence, turning the magnet inside the motor. Brushed motors use a commutator and brushes to sequence the motor. Regardless of the battery used, brushless needs a brushless ESC and brushed needs a brushed ESC. You cant modify a brushed ESC to work on a brushless motor or vice-versa. the price for a brushless ESC sounds steep, untill you realize what its doing, and how fast it is switching current between 3 wires, not to mention the ESC has to sense where the magnet inside the motor is at any given time so it knows which wire to energize next, and to make sure the motor spins in the same direction every time it starts. to add to that, you have different timing options for different motors, low voltage cutoff settings, overcurrent protection settings, prop brake settings, and for heli's governor settings. $50 for a phoenix 10 ESC is a bargain. you need to specify what type of plane you want to upgrade, size/weight/stock power system, battery, ETC to get better answers on how to go about a low cost upgrade. If the plane is relatively small, $100 will get you a nice brushless motor setup. Most of the time simply switching to Lipoly will lower the weight~increasing performance and run time.

Saito 91 15x4 wide, 2 futaba 9405 servos on the tail, 3010's on the ailerons and a mini on the throttle. redundant RX packs, 1650 5 cell and 720 5 cell. JR R900s pcm receiver. robart super ball link control horns and central hobbies carbon pushrods. the plane balances at 4 3/4" with the batteries under the pilot, and no other weight added. Kevlar thread covered in heat shrink tubing as a tail brace, .014x.25x48" carbon tape glued on the wing to cap the spars. reinforced aileron servo mounts and ribs. glassed the firewall and landing gear block, reinforced the wing nut plate. replaced the wing hold down dowell with a piece of brass tubing with a carbon tube inside of it. The World Models fuel filler valve, dubro pin style hinges, pinned with alum tubing. removable rudder. polished landing gear, dubro tailwheel bracket. i re-covered it, so i was able to go over every glue joint with thin CA. Should fly just fine, and it should hover at about half throttle. What control throws are you guys using on low rates? my high rates are 40 degrees on the ailerons and 50 degrees on the tail. should i set low rates up according to the manual? or will it be fine turned up a bit withsome expo? im used to flying insanely overpowered electric 3D planes, and most of the time i dont even set up low rates, just expo.
