Do you know if Fliton is going to make these mods to the regular color scheme? and how would I know if I was ordering a V1 or V2? It makes me want to wait a bit.




Dr. Watson, I presume! Sorry, I just could not help it! Now, your question is a good one and it is suggested that you ask Fliton. The email is;
[ edson@fliton.com ] and why not post the reply as I am sure that others would like to know.

Status: offline 		Papa, I used an AXI 282012 on 3 cells Evo's 2170 an APC 13X6.5, CC45 and four HS-65's. Very light and simple. That set-up could not hurt the battery or motor. Not ballistic, but adequate. Made the airplane a real floater. Probably could use a little more prop. One of the new planes has the same setup. The other is 4S.
Now I am really liking the 4S and Hacker 10XL. Great power(!) and the little extra wieght adds momentum. I tail mounted the rudder servo on the 4S,,,
It is spooky how much these plane feel like a 35%-40% aerobat!
I have been waiting on a couple of the Castle BEC's,, hope they start hitting the market soon! Hitec will introduce their digital 5082 and 5065 and I want a bullit proof BEC for that! Also the Spektrum is vunerable to 'brown out', So Castle,,, hurry up and get these BEC's out there!

Status: offline 		I am really curious now when I will receive my planes. Today the "big brown truck" passed by (actually here they are orange!) to deliver the shipment from the US containing motor, batteries etc. The planes will arrive from China directly, but when?? Anybody out there that also will receive from China? Did you get something?

Status: offline 		Volkert,

Did they (either Fliton, if you ordered from them, or the company in China) send you a shipping notice or a tracking number? If not, send them an email and get some sort of expected delivery date. Don't they realize that we have to take extra medication to remain calm when we are waiting for a "NEW" plane to arrive! What's wrong with them????????????????????? Be sure to let us know what is going on.

Regarding your battery, if you ordered a 3S 4000mAh pack and got a 4S 4000mAh pack you could use it on the AJ! But, you would have to use a BEC, with the 4S pack, to power your servos. The X-55 ESC that I am using can handle the volts from a 4S pack when used with a BEC. What ESC are you using? Also, you might want to check out the Castle BEC. By the way, I agree with you about not joining two 3000mAh 7.4 packs for your AJ because it's better to use the one proper pack for correct power, duration and balance. Let me know the results.

Thank you for the power set-up info that you have used on your two great FG-AJ's. I think that I am going to favor a 4S pack with the new Castle BEC, but I still plan on testing the various combinations and the Watt meter will tell me what's what. Have a good weekend.

Status: offline 		PJ: the US shipment had track and trace. I could very well follow it flew over in a day , got stuck in customs for 11 days and arrived here the day after. So much for fast shipments! On the China shipment no info yet, I emailed Fliton yesterday on this. Both shipments are from Fliton!!

Feeling so sorry for you, have dug through 4 cabinets of misc. stuff, but no 1/8" axel, otherwise one would be in the mail. The machine bolts provided seem to work ok, although do not like them either. Finished the Katana MD, supprised I got it to CG ok with the battery. Now going to work earestly on the AJ. Should maden next weekend as not a bunch left to do. Intend to use a Castle 60A with new Castle bec and see if she will like the 4,000mah cell. If not, looking forward to your findings battery wise as we have the same motor. New experience last night. Ran Katana axi 2808/20 on 3,000mah bat., watt meeter said pulling 24 amps. Hay, I can use my Castle 35 on this and save the 54 for the AJ. Exchanged controllers, hooked her up and got the correct beeps, then the controller went up in smoke. Guess my electrical theory needs a little more work huh? Apparently the controller must be equal to the batterys max amps regardless of the motor demand. In this case battery is 20C, 60 max amps. ,demand on same 24 amps. Still wondering why poof? Gonna bug Red S a little. ENJOY

Status: offline 		It seems the shipment from China failed, so they will ship from USA instead the two planes. All this by Fliton email info. Although this is a bit of a cockup, I must say I am positively surprised by the responsiveness and kindness of the Fliton people. Hurray!

Volkert,

Those Fliton guys are the best! I have found that they are loyal to their customers and are most accommodating. Edson, Sam and the crew are "young lions" and sure have accomplished a great deal in in the RC arena. Let us know when your planes arrive.

Status: offline 		Rmenke,

Thank you for taking the time to look through your inventory to see if you had an extra set of 1/8" axels. I found a set at my LHS, yesterday. Sorry to hear about your burnt-out ESC. Usually, it's hard to know what actually caused the issue, so it might be advantageous for you to send it to Castle (ATT: Joe Ford), he is the Chief Tech. and see if they can analize it for you to determine the problem. Hey, they might even send you a new one. You never know, right?

With ESC's, I've found that it's safer to use your new theory; "Use an ESC whose amperage equals the batteries max amps output." Also, with any 4S or higher Li-Po pack a BEC should be used to power the servos. Then, static test your system with a watt meter! It' the old addage......"It's better to be safe-------than sorry!" Ohhhhh.....Yeahhhhhhh!!!
At full throttle, note volts & wattage, as well as amps. Then V x A = Watts is a sort of double check of the figures. For me, it's then helpful to determine watts per pound
just to make sure that the battery/prop/motor combination is proper for the type of plane. ie: @65-75 w/lb for basic general flight ----- @90-100 w/lb for agressive sport flight
----- @120 w/lb and more ----- for 3Dflight. There are many different opinions out there, but this theory has worked for me. Let me know what you think.

Thanks for the heads up, will send it in to Castle, and Joe. Your approch of watts relationship to weight seems standard for most of the electric guys and realistic to me. Overall, think we would be better off and more accepted by others by using the normal power to weight relationships as a general guide. I notice that some motor manufacturers are starting to show a glow engne equivalent. Expressing motor output in pounds of thrust would be more meaningful to me. A watt meeter test is as nessary as a glow plug for glow engines. I would hope we all check for equipment heat as a further test of correct ballance of motor, controller, and battery. Working hard on the AJ 330S, should maden the Saturday, with or without the 1/8" axels. Found some on my "Miss Ashley" sitting dormant for a while. Keep up the great work!! ENJOY

Status: offline 		Rmenke,

You are correct about motor comparisons. It is truly confusing because there is no standard guide and all the different Mfg's have their own special rating. Hobby-Lobby has done a good job of rating their AXI & Atlas brushless motors (see Catalog 49 pages 67-73). Horizon also has a logical rating for their E-flight brushless motors comparing them to the equivalent glow engine. It's still somewhat confusing and that is why it makes sense to rely on the good old Watt Meter. Also, when using different size props with a certain motor & ESC, to get to the best power combo for the type of plane that one is building and the individuals' flying style, a watt meter is an invaluable tool.

Regarding electrical heat build-up from operating our electronics and the theory of disappating that heat, this concept needs to be of more concern to the modeler and Mfg's as well. Too often, it seems, correct intake and exit vents are not given much attention. Lately, it has become better, but
it's imperative to have proper air flow over the ESC, battery and Rx to keep their operating temperature down. Also, the "Exhaust" opening (or vent) should be about 2/3 larger than the incoming air opening (or combination of openings). Well, that's my lecture for today! Hey, did I seem to get carried away with all of this????? Oh, just remember that tomorrow there will be a test on todays lecture and I do expect all students to get a
B+ or higher!!!!!!!!!!!! Ohhhhhhhhhhhhhhhhhh.......................Yeahhhhhhhhhhhhhhhhhhhhh!!!!!
