Oops! Almost forgot.

I completed a new search regarding our beloved GWS A-10s and I found two links some of you may be interested in reading and movie threads you may wish to see. These are spring last year offerings, but in one video, the pilot actually takes a half step and with a gentle bowler's swing, launched his plane without a hitch - interesting landing though. Try these:

Enjoy!

Hey A-10Flyer:

How about expanding your comments a bit more? I have been waiting to hear how your flights went with the new EDF55-300. I'm new to electric, so I do not know much about escs and the li-poly batteries. I know from your description that you have 3 wired in series, but what is the mah rating and voltage? I want to use li-polies, but there is not a comprehensive book I am aware of that assists those of us new to electrics with this information.

You appear to be well informed! Ever thought about writing that kind of book? If you or anyone else should decide to, don't use "For Dummies" anywhere in the book. We are not dumb; we are just new to the sport and trying to bring others into our hobby. We can read and understand plain language about a new and ever expanding new power source for our models.

I appreciate your posts, as well as those of others who have gone before me with the A-10. I ordered the 300H version which I should receive no later than Tuesday the 13th. Hope to hear from you before then.

Hey dbl,

I appreciate the comments but trust me, I am a DUMMIE!! Really, I know very little about electrics. There are others here that know "books" more than me. Like you, I am low on the learning curve. I am using a 3S2P 2400 mah pack and so far the motors are still running. Just don't go 3S with the 50s.

dbl8,

Contact Hobby Lobby re the LiPol question. They're very helpful.

A-10 Flyr and Woody 51:

Thanks for the information. I'll give the 3S2P 2200 a chance when I receive the package. I have a mini Telemaste on the assembly board and found Hobby Lobby to be quite helpful.

I surfed another site earlier today and found streaming videos of successful GWS A-10 flights. Both were hand launched. In one video the pilot launched the thing as if launching a feather via a single step bowling release (his landing was unique also. Take note that most of this comes from online forums conducted in the spring of 2003. If you would like to check it out, visit:

www.e-flightline.com/movie.htm or
www.rcgroups.com/forums/showthread.php?s=&threadid=94246&perpage=15&pagenumber=6

I don't remember which site it is, but there are two A-10s at one site, both with videos. Again, thanks for answering - believe me it helps.

it looks as all you guys have not seen what is going on with motors....
If you really want to fly... go brushless.... and it can be done with cd-rom convertions...and you gain 30% throust.... and loose 30 % weight on motors.. ok.. the ecs... is more expensive and you need two... but you will love it ...
You just have to look what Niels Polfliet from Belgium did in the thread ultra light cd-rom on steroids...

Claus, for my dimes worth.

Although I would love to spend up big on my A-10 frankly, I'm not going to spend that sort of money or time on this kit.

I also have a couple of Alfa electrics, one flown for the 1st time a couple of weeks ago and the other for the 1st time yesterday.

Believe me, they are worth spending up on for brushless coversion, as I decided to do on my 1st one.

The 2nd, being an EDF, flew with the supplied Speed 300 and the performance was excellent. There are some issues with brushless conversion on this model (to do with the Fan Unit) that I still have to sort out, so it will stay Speed 300 powered for the time being.

I have another (The FW190 ) on order and will probably do the same for that when it comes.
The Flying Styro range of kits are also worth it.

The GWS A-10 doesn't fit into the same class in my opinion.

All I wanted when I ordered my A-10 upgrade kit , was to (finally) get a satisfactory performance increase from the model, with a mimimum of mucking around and as cheaply as possible. Hopefully I will get 12 months or so out of it. After that, I don't really care.

Hi all,
The second one within a month period.
after reading a lot i decided to go on with Lipoly 3cells 1500ma and EDF 55 150

.
Not to use weight for correct CG and to save my batteries in a future crash i build a foam slot int he noise.
Also bamboo stick added.
See attached photos.
Flight performance??
I hope it will be ready for the weekend.
BR

I'm from Spain.
I have my EDF55-300H kit on my hands, but I have some doubts before mounting the kit ...

I LIKE VERY MUCH your solution for the LiPoly compartment. I was asking myself how to do it, but you are the answer to my questions

WELL DONE!!!

But one question: If the motors are up to 9.6v, how can you put them to work with LiPoly? 2S are underusing the motors and 3S will burn them in a few flights.
Do you know any electronic circuit that limit voltage to 9.6v? Can it be done? Anyone?

Another question I have is: You have to sand very well the nacelle-halves to reduce drag, and you have to glue the nacelle-halves (in pairs, of course). But, how can you change the motors in case they burnt? Do you have any happy solution like the battery compartment?

Thanks

Dear A10Flyr:

Thanks for the clarification. Are you still using the Jeti with the EDF 55 set-up, or did you change to another controller? I noticed in some fall posts you exchanged with the guys at E-Flight that they were using two separate controllers in addition to some other expensive equipment. I'm like many others in that I just want to enjoy the plane, not wind up cooking and doing the dishes the rest of my life to regain the Mrs's favor. I already had to buy her a van to calm her down when I bought my bass boat and one of those big TVs when I re-entered remote control modeling four months ago. So, I don't want to burn up all my brownie points on one $83.00 model (I can get a lot more of these before reaching the amount I had to give for that oversized tube). Woody 51's comments to Clausxpf make good sense, and I agree with him 100% when it comes to the A-10 investment. I have a Telemaster 66 (.40) that has been on the building block for four years and a mini Telemaster (electric) on the building boards that is almost ready to cover. At $29.90, the Mrs. thinks she is ahead for a change, and I want to keep it that way.

Now that I have a good idea about what battery to use, I will now concentrate on the controller and how to wire the engines. (Is your wiring the same as the stock method or did you have to get creative?)

Again, I thank you for your posts. I have derived a lot of information from your trials and errors and look forward to any more information you can share. I'd say you know a whole lot about electrics. Each step you took after frying the 50s was logical and yielded success. By the way, no dummies here, just modelers doing what modelers do - trying to get um airborne and keep um there.

That wasn't me on e-flight. I used a Castle Creations controler

Yes my wireing IS stock.

Thanks. Don't forget the bamboo skewers! They work!

Hi,
With throttle management i hope to have lot of flights (if not crashed) with the stock motors.
In case of burned motor you have to find the small hole in the fan, open there a small hole for the allen key and unscrew the two allen screws. Then try to remove the impeller (it is very tight in the motor).
Two small screws and remove the motor.
Hope it helps.
I'll send photos

Yes, finally it flies.
setup 1-2mm more movement at aileron and elevator (wrong was too sensitive)
with 80% throttle and a little trim up the plane still needs up to maintain attribute (i don't know why)
The fly time was up to 6 minutes.
The landing was too difficult.
At the end only cosmetic scratches and the landing system bended
