Hi!

I have scorched my quite expensive regulator, and upon closer inspection i see that there is 4 FETs in the H bridge of only 1 phase that is toasted.
These are easily accessible without even disassembling the unit, and replacing them would be a piece of cake job.
But, i can't find the transistor anywhere.
It's marked 4410 BE5C13.
Can anyone look up that number in the Jaeger?
It would be of great help, as i don't have access to the catalogue myself.
In advance, thanks :)

How important is it the way you route the antenna. The manual seamed to leave out some cool ideas the Transmitter manual had. For one using a little piece of conduit through the fusealage to run the antenna through for support.

Another tip the Trans manual stated was to stick a t-pin in the Vert. Stab to attache the antenna too with a rubber band. The Great Planes manual just wanted you too tape it to the side and let it hang.

Any help would be cool. Thanks.

Time To Launch a Cub on its Maiden: 34 Hours

I'm sure its a dumb question but can I charge directly from the charger to my pack? I have a 500mah 7.4v common sense RC pack jst and balance tap (don't know what type?). Or do I need one of those nodes? Also, where is a good place for 500mah-800mah 7.4 packs... hobbycity is completely out.

So, I've been doing a lot of reading and since deans connectors seem to be the way everyone suggests, I went for it.

I changed all my lipos, nimh, chargers, and planes to deans connectors...

It looks like they make a solid contact for the most part but they seem hard as hell to disconnect. Did I do something wrong, is there a trick, or is that how they are? I'm afraid that pulling on the cables will cause them to disconnect so I'm pulling on those small connectors.

My ESC (Electrifly C-20) is rated for brushed motors under 25A. Can, I use it with a lipo (2 Cell, 10C, 800Mah) on a pico stick???? I know the standard answer but Tower Hobbies website has me confused.... it says two things. 1."When using this speed control with Lithium Polymer (LiPo) packs, care must be taken not to over-Discharge the packs as the low voltage cut-off on this speed control is NOT calibrated for LiPo packs. If LiPo packs are over-Discharged long term loss of capacity may result. To prevent over-Discharging, land the plane as soon as there is a noticeable loss of power to the motor." 2. (Tech Sheet) "Low Voltage Cutoff: .80V per cell for NiCd/NiMH, 2.75V per cell for LiPo Does this second detail kinda contradict the first statement?

Not sure how real this is or if it's even possible but it's nice to know someones even working on it.

Wondering which way to go - the EP version is only $10 more but the non-powered version may be more interesting/challenging, and its lighter wing loading (I assume) will make it thermal better (this is Phoenix area and thermaling, not slope soaring, will be the deal).

I already have a lot of hours with the EZ*, and a few flights with the recently built Graupner Elektro-UHU ( a smaller but better thermaling R/E EP sailplane). Also lot of hours with a brushless HZ SC, R/E only but will start flying it with ailerons tomorrow).

Now- the multiple questions -

1. The EP Easy Glider will enable better thermaling than the EZ* and UHU, but the non-powered Easy Glider should thermal even better. Would it make sense to get the EP since it is only $10 more, and remove the motor/ESC/large battery after mastering it? Or start with the non-EP version (see Question #2)

2. For the non-EP version (or converted EP version w/o motor), I would like to experiment with bungee launching since I have never done that, and then experiment with aerotow (find someone at the field to fly the tow plane). Make sense, or too much fuss for the dolllar?

3. Now if the aerotow is practical, would the HZ SC suffice (it has about as much thrust as it weighs, and can climb at about 60-70 degree up), OR would a bigger, more stable tow be needed?

4. In general, do towplanes need to be taildraggers, or is tricycle gear an option? Are ailerons on the tow mandatory, or R/E good enough?

I know this all is a bit involved, just wondering how to keep challenged without spending major bucks on 3D aero, EDF jets, etc.

If I go aerotow, Hobby-Lobby has some nifty servo-actuated towing releases for the towplane and sailplane, just like the real thing (I used to fly the Schweizer 2-33)

Hi

This my first post here on this forum, so a warm hello from me. I have a Multiplex Lucky slope soarer and i am looking to convert it to electric, so i need some advice from you pro's on recommended set up's. Looking for a fast glider within its structural limits.

The fuselage is quite narrow so i am not sure this is possible to convert. I believe the mini-kult comes in an electric version and it looks very similar to the lucky, so could be possible. Max width for batery approx 50mm and for the motor aprox 30-40mm depending on where i cut the nose off.

Here's the gliders specs.

Wingspan: 1980mm
Fuselage length: 1111mm
Weight: 1400g
Wing area: 40dm2
Wing loading25g/dm2

Thanks

okay, im still looking into the e-flight texan. i think the one thing that really kills the price for me is the RX. is there any other cheaper ones that would work guys? if so, can someone please send me a link. i would like one that could be used 7+ channels.

Howdy all:

I would like to upgrade the motor on my HZ SC in order to provide a longer flight time. From my reading here it seems as though a brushless motor is more effecient and will therefore allow flight time to be longer.

I don't want to upgrade the electronics or to a LiPo battery, so the motor needs to be compatable with the stock RTF and ESC out of the box. I have tried the search feature and can't seem to find anything that would meet my requirements. (probably because I have no idea what numbers I should be looking for. ???? )

Anyone have an idea for me? Thanks ahead of time.

Respects,
Whipple

Hi! I have a Multiplex Easy Star, (get one!) and I love it. I can now consistently land it:tc:. I'm not too good with wind, so I'd love a slow indoor flier. Currently, I've been looking at these:

If you have any of these planes comment on:

• Speed
• Ease to Fly
• Ease to assemble
• Total cost (I have four spektrum micro servos, a DX6, but no spare receivers, motors, lipos, etc.)
• Performance in non-perfect conditions
• Anything else you love/hate

Ok, So I have my Slow Stick, now I am looking for a decent place to crash it, I mean, learn to fly it. I'm in SoCal and didn't have much luck searching the board for a related topic. Any help?

I have a power supply from an old Dell. The laptop is long gone and I was going to throw away the power supply but it occurred to me it might be useful for charging RC batteries, but I'm not clear on what voltages/amps are needed or harmful. Any guidance would be greatly appreciated :)
Thanks!

Here are my charger and the power supply:

I like most all types of modeling. Lately I've been building planes from the 60's, like the ones I had years ago.

I don't mind older ones, but the individual plane has to interest me.
I also update and strenghten the structure.

I really am enjoying this.

Only thing is I am using electric motors for power.

In some forums this is heresy, most of the posters not only want the original engines, they want the original radio equipment.

Other forums seem to think free flight planes from the 30's or 40's are the only true "old planes".

Am I the only one who wants to do this?

Anyone else out there who wants 60's and 70's planes, with modern equipment and electric power?

Please post your views.

I had this idea of using 4 engines facing downwards, and we could use our servos to tilt them for rolls and yawing and other aerobatic maneuvers... i was thinking of this setup for a near ground extreme maneuverability type craft where the control surfaces are thrust(by reversing thrust output)

so this is how the setup(s) would be....

4 egines with downwards facing props
this would do VTOL by lifting straight up... then for forward flight we would push all 4 engines forward and control up and down by tilting the rear or aft(forward) motors, this would be like thrust verctoring...
the servos would be hooked up so that when you would do a roll the motors would either A) be rotated so one side(both motors on either side) would turn downwards and the other upwards... so it could do a really tight roll(probably several), B) this setup would have reversable pitch props.. so that we have no moving motors except for horizontal movement forward and backwards movement...

for yawing its simply slowing down two sides of the motor....
what i like about this idea is that you can slow down and fly it like a heli, so if you needed to get a fix on a certain target you could slow down pull back(makes thrust push forward so craft moves backwards) and you could hover and then rotate around(this is not yet thought of, maybe it'll be mixed in with the 4motors but maybe not)


im just thinking of future projects i would like to try and give a hand at... it would be pretty cool... i'll have simple drawings for more ideas...
this is like a theoritical idea....
it probably has been done before but i would like to make my own version

the craft will still have wings but its main source of lift/thrust is the 4motors... most likely outrunners...

Hi,
Ok, I just won off Ebay for $90 a brand new Futaba 6EX 6-channel 2.4ghz radio (http://2.4gigahertz.com/systems/futk6900.html)... this package did NOT come with the receiver so I need to buy one...

Now, I'm looking to buy for my first airplane... the kind of planes I'm thinking about are something like one of these models.... something with a 30-40 inch wing span... that'll do 3D... as my skill increases...

Now, my question is, what receiver should I buy? There 3 possibilities:

Futaba's receiver page
http://2.4gigahertz.com/receivers/index.html

http://www3.towerhobbies.com/cgi-bin...?&I=LXTNB6&P=7
R604FS 4-Channel Receiver - $120 (for a 4 pack)

http://www3.towerhobbies.com/cgi-bin...?&I=LXTHL6&P=0
Futaba R617FS 7-Channel 2.4GHz FASST Receiver - $95

http://www3.towerhobbies.com/cgi-bin...?&I=LXUDS7&P=0
Futaba R616FFM 2.4GHz FASST Micro Parkflyer Rx 6CH - $60


Most of these style planes do not require more than 4 channels. Though I've been looking around and I can not seem to find the 2.4ghz 4-channel receiver in anything but a 4-pack... (where are the singles!). I don't need 4... even 2 would be more than enough.

My only side consideration is that eventually I may add my Esky Belt CP (6CH) to this new radio... I'm undecided right now as the stock radio seems fine for now for the heli.

So my thought is the more expensive 7 channel receivers is a waste of money due to unnecessary channels. So should I just buy 1 Futaba R616FFM 2.4GHz FASST Micro Parkflyer Rx 6CH so I can use it on my plane, and have swap-ability to the heli later, if I can snag a single 4CH Futaba 2.4ghz receiver from somewhere??

Is that the most sensible buy?
Anyone know where single 4CH receivers can be bought?

Advice please...

When I plug a 3-cell lipo into my 40A ESC the ESC begins to get hot even before I turn on the motor! Need suggestions as to why:confused:. The motor is a United Hobbies 20-40 17A inrunner mounted in an L-39 Albatross. The ESC is a UH cheapie. After flying the plane the ESC is almost too hot to touch. Help!:blah:
