<span style="font-size: larger;"><span style="font-family: Tahoma;">Name's kodiak536.

Just getting into electric EDF jets.

I've flown balsa wood &amp; paper skin model years ago as a child....mind you, I'm now 51....and 1/2

As bad as the reputation online for them, I just bought a F-16 from bananahobby.com

Ordered it Sunday night and just received it few hours ago...not too bad considering their reputation.

All parts accounted for and no apparent damage, it was packed very securely and no loose parts.

Being that I bought just the airframe only model I have some questions as to what &amp; where to purchase the needed parts to complete this plane for flight.

Folowing is what's required, according to their picture book instructions:</span></span>

<span style="font-size: larger;"><span style="font-family: Tahoma;">8 CH RC
9 X 9G servos
50A Brushless ESC w/5A UBEC
2400KV brushless motor
18.5V 25C 2200mAh Li-Po Battery.

Will these be sufficient or will it be underpowered? I have no plans right now to hook-up or activate the vectoring...got to learn how to fly RC before I can do stunts.

I'm former USAF so, I do have knowledge of how the Aircfat fly and do have actual fighter/trainer flight times.

Thanks &amp; Aloha</span></span>

9G refers to the servo size, UBEC is a battery eliminator circuit which is an integral part of the ESC (Electronic Speed Control which provides the control of the motor). Is the fan included with the kit? You might need to procure that also, though I am not sure. Strongly suggest you don't go cheap on the equipment, quality is really cheaper if you don't loose the airplane to electronics failure. Do your homework on the battery. These are not cheap and you don't want one that will not last very long.

Which F-16 is it?

9 9-gram gram servos, must be a vectoring nozzle to it. 2 for the thrust vctor 2 for aileron 2 for elevator one rudder one nosegear 3 retract. Makes 10. If you don't have a rudder servo, and only nosegear steering you need the t/v to stay straight on the runway. Personally, I add in a rudder to planes that lack them. I don't believe in driving a plane off the edge of a narrow runway and toasting it without even getting airborne.

Be careful setting up mechanical retracts. The servos can overload when the throw isn't set right. (center the servo on another channel. Reduce gear throw to plus and minus 30 percent to begin. put the gear halfway and make your link. Then actuate the gear. Best to do one gear at a time. Once they are in the plane, there are more bugs to work out. Gear doors for instance. Don't jam up the servo for long, unplug something)

You've bitten into a beast of a project for a newbee.

<span style="font-size: larger;"><span style="font-family: Tahoma;">Thanks for reply.

Yes, the fan were included and I don't plan on skimping on electronics. That's the main reason why I bought the airframe only, so that I can pick &amp; choose the best I can afford for the internals + radio system.</span></span>

LOL, a beast it is. As a fromer USAF Aircraft maintenance specialist, I've always been fascinated with fighter jets and had the previledge of acquiring several flights on jets. I also held a "run-up" license for these jets I worked on and that made things alot more interesting. Unfortunately, no F-16 flights to "brag" about...

Thanks for your pointers on the retracts and I'll keep that in mind.

<span style="font-size: larger;"><span style="font-family: Tahoma;">
Cool, thanks. I've seen these sites myself. In fact, I was going to order a plane fron Nitroplanes but, their F-16 didn't look as good as the one from bananahobby, flimzy landing gears with no retracts, about the same price.

As for the battery, the manufacturer suggest 18.5V 25C 2200mAh Li-Po. Do the actual discharge rate of 25C important or can I go lower/higher? How many cells? How about the 2200mAh? could it be higher/lower?

Also, the motor recommended is 2400KV outrunner brushless for this. Should I look for the exact that's recommended by the manufacturer or ???

So many questions, so little time...

What do the experts recommend? Inquiring mind want to know...</span></span>

Hello. First post here. You're not alone Kodiak. I'm 53 and just got into EDFs myself, and electric flight in general. I bought a JPower T33 inkit form from Toysonics before practically everything went out of stock there so I could use better electronics. I could have saved more if I got the ARF version but I wanted to use my own tried and true units.I installeda Hitec 55 servo for the elevator and two Towerpros for the ailerons. I've had a few of these on hand and have never had a problem with them. ESC is an EMAX 25 amp unit along with program card to make things easy. With free shipping and great service from Hobbypartz in L.A. county Iwent withSky Liposand got a few 1000 mah batteries to try out before I use a 1300. the 1000's seem to balance the plane very well while the 1300 puts it nose heavy. But I'll try itlater nonetheless. Deans connectors on everything.After selling an eleven year old Hitec radio along withsome misc O.S. and K&amp;Bmotors and supplies that were about 28years oldand NIB,I just went out and bought a new DX6i from Evolution Hobbies here in Redlands,CA that has the new DSMX technology along with a 6115e receiver. I have seen these used in other planes that have beentaken out to surprising distances for what is termed as a parkflyer receiver. I'm new to computer radios and all I can say is that Ithink the technology through the years has just madethis hobbybetter. After I get around to doing amaiden flight I'll post pics and areview from a newbie's perspective.

<span style="font-family: Tahoma;"><span style="font-size: larger;">Thanks for your input.

I'm yet to find useful links/information on what I really need so far on this site. Some of the items you've mentioned, I already checked out and are considering them.

Here's my primary list:
www.hobbypartz.com/topromisesg9.html
www.hobbypartz.com/60p-70mm-edf-combo.html
www.hobbypartz.com/ubhvoulbe.html
www.hobbypartz.com/98p-25c-2200-5s1p.html
www.hobbypartz.com/60p-dyc-1004.html only problem with this one is that it says a/c adapter not included and they don't seem to seel it.

My main problems right now is the finances, if I buy the electronics now, it'll be a while to get the radio tx/rx...meaning I won't be able to test out the electronics to see if they even work before warranty expires...opposite is also true for the radio tx/rx.

Can't really win, can I? I can't fork-up $500~$1,000 right now at one time.

May be I can get the elctronics first and have the guy at the local hobby shop test them out???

If you need a motor, some things to consider. In my F-16 tv, I had to add weight to the tail. I flew it first with the factory CG, and you should as well, a longer static margin is better than a short one. I've set up finally with a 5cell 2200mah 40c pack, outrunner 3300kv 1000watt Cyclone and about 2 ounces of lead in the tail. The motor and lead balance the 5 cell pack to about, 1 cm behind the factory recommended. You should start on the CG set in the plans first, and zero setup on the flight surfaces. Get ready to hold up elevator, well, that's me. Don't STALL the aircraft with too rearward a CG or by applying up elevator against little airspeed. Jets need airspeed for the control surfaces to work, there's no propwash. I flew it maiden from a 75' paved surface. The wheels are small.

I've contacted you to further set up an assistance communication, so you can be specific, and so can I. I've built functional R/C aircraft since 1979. I'm not the greatest, nor am I exact scale, or a master builder, but I can help with the hurdles.

Do you have hardware? I always like to have extra, gives some extra options, and some building experience has told me to save ALL hardware, especially from old or crashed planes.

I will attach a pic of the fan in my LX F-16, which is the same or very similar to the Blitz.

Hey Kodiak, I just wanted to suggest, finding out the true specs and actual figures on fan units, is facilitated by going onto YouTube. Search EDF. Also, Extreme-RC guys down under have great handles on the facts. the url is http://www.extremerc.com.au

Another site with good specs on the fan performance is RC-Castle http://www.rc-castle.com

As well, Philip workshop RC has performance specs from the motors listings http://pw-rc.com

<span style="font-family: Tahoma;"><span style="font-size: larger;">O.k, I ordered my initial components. They should do fine for the time being.

One other question on radio Tx/Rx.

I found this online and are looking for any input: </span></span><span style="font-family: Tahoma;"><span style="font-size: larger;">www.airtronics.net/index.php/airtronics-rds8000-8-ch-2-4g-mode2-w-1-tx-1-rx-only-rds8000.html

It sound pretty good for the price but, you know the old saying...if it sounds too good to be true...?

Thanks.

Kodiak536- I have flown R/C models since 1952 and fly model cubs to turbine jets. I strongly suggest you get with a local club that has experienced EDF fliers and get their help. An experienced model instructor can save you a lot of money.

<span style="font-family: Tahoma;"><span style="font-size: larger;">Thanks for your input.

I don't plan on maiden crash so, I plan on buying a beginner's park flyer to practice on while I build this EDF jet.

I just ordered the Airtronics radio yesterday and are planning to use it to familializing myself with it.

Once I feel confident of the controls of the Tx and the F-16, I'll go fly my EDF and terrorize the local park goers
</span></span>
<span style="font-size: larger;"><span style="font-family: Tahoma;">Now, all I need is a battery and charger to complete my list.

Thanks.</span></span>
