F16viper Welcome to Hobby Squawk. Very glad to have you onboard.

The link I posted is for the Official 64 mm A-10 forum and you will definitely find good advice there.

Best, LB

What battery configuration are people using on this model? I was hoping to use two SMC 6S 7200/6200 or two SMC 6S 5900/5100. To my disappointment they don’t fit in the front battery area.

I've used HRB 5000 & 6000 ma packs with no issues. I just move the 6000's back. Think I trimmed the hatch a bit.

I have a freewing 64mm edf and does anybody know wich is the best battery to use for it

[Corsec]

I use 2 SMC 6200/5000. Had to trim the bottom of the canopy foam a little bit then they fit well. Moved the electronic board back a bit to slide the batteries back far enough to balance. Flies fantastic. Lots of full throttle acrobatics I end at 7:00. More of a cruising flight and I’ll stretch to 8:00-9:00. Haven’t landed below storage voltage yet. Highly recommend.

That was part of the problem. But, in the end I just bypassed the freewing control board and wired the throttles directly to the receiver with a Y cable, after I disconnected on of the BEC feed wires, walla...problem solved. Thanks for responding tho....

HELP!! So, have the A-10 80mm version. Opted for freewing 120 amp ESC's with reverse. Connected both throttle leads to the flight board in the aircraft. When I connect a battery/s one motor gives me the beep beep which the ESC documentation says is an over voltage. When I disconnect one engine (either engine) the other works fine. So I know the ESC isn't bad, or the motor, as if one were bad then they wouldn't work individually. Tried disconnecting a red power lead from one of the throttle leads (thinking maybe it only want's one BEC voltage), same thing. So...I have two working motors, two working ESC's, but when I try and connect them both, only one will operate.

Possibly it does not work out, if both ESC's have a BEC?

Gents, anyone have the measurements for stock front and main wheels including axle? I am considering them for a project.
Thank in advance.

I have a set of JP Hobby 12s 90mm fans and custom 12s 10,000mah batteries from a recent experimental project. I know these huge batteries would be twice as heavy as the standard setup, but the power system should more than compensate for that in the thrust to weight ratio regard.

Thoughts on how a setup like this would fly? Wing loading way too high? Battery bay large enough?

[JPD]

Two questions here. Both related to A-10 ESC's. So, I go the freewing (reversible) ESC's for my A-10, I also purchased the hobbywingESC programming box. When I connect it up, I get the lights and ability to set parameters as I choose. But, when I hit OK, the "connecting" light comes on and never goes off. It says you have to power down the ESC's then power them back up for changes to take effect. When I do that and put the ESC programming box back in, it shows none of the parameters I set have been programming into the ESC. Anybody have any experience/ideas with this? It seems simple enough and ⅔ of it works, but the actual programming isn't happening. Second question, I have two Spektrum/Avian 120 amp esc doing nothing, (which are much easer to program thru the transmitter) which I would prefer to use. But, they don't even come close to fitting in the space allotted for the ESC in the nacelle. Even if I remove the fan. So, second question is has anybody figured out a way to mount Spektrum 120 amp ESC's in the A-10 nacelle's? I see that if maybe i did a bit of trimming it maybe could squeeze in there, but then there's no clearance of the wiring harness. Ideas?

Hey fellas, Just received my A-10 and a problem dawned on me. So, I was planning on using Spektrum ESC's which have about a 6 inch lead...yet I've got 30 inches to go to get to a battery. Yet a quick search on line reveals that the longest extension you can but for a IC5 is 6 inches. Does anybody know if there's a maximum length you can extend IC5 connectors due to current under load? It's easy enough to buy a couple of connectors and the wire and make my own, but now I'm wondering how much loss I'll incur do to the extra nearly 6 feet of wire between the ESC's and the battery.

It is a very good idea to fit capacitors to the power leads when they are longer than 8". The issue is not loss but ripple which is known to destroy the esc. The stock A10 esc's come with extra capacitors already fitted.

[Alphonso]

Thanx will do.. of course next question(2 of em) i want to use them on al 37 and f4 phantom fwing.. so any mods req.....?. But will i need different lipo charger

No issue using 4.35V lipos in those models. Yes your charger needs to be able to charge to 4.35V per cell. SMC do standard voltage lipos too.

Email Danny at SMC racing, telling him what packs and connectors you want. He will arrange shipping direct from the factory. Did it 4 times last year, it is really cheap too. Pay via PayPal.
No mods required to use them in this plane with stock electrics.

Hi guys,, was wondering if anyone knows if the smc 435 volt packs r available in australia,, cant find any,, not looking hard enuf maybe,, and is there much if any mods to airframe electronics req for the use of these packs... even 5 or 6 minuts sounds good to me.... thanx in advance

[JPD]

Awesome, detailed, comprehensive, well thought out and comprehensively explained. I can't thank you enough for taking the time and effort! Thanks Hugh! And nice bad a** looking aircraft!!

Does anybody out there have a Spectrum (DX8e) flight profile for the Freewing A-10 80mm EDF they'd be willing to share. The jet is on its way along with some 80mm X-Fly motors/12 blade EDF, paired with Spectrum/Avian 100 amp ESC's and a Spectrum AR8360T receiver. I'd like to get a starting point for AS3X/SAFE mode settings in the flight profile if I could based on real world experience...I've peeked at the manual and it seems fairly comprehensive insofar as throws/deflection for empennages, but I've had to start from scratch on a few other models after finding the flight envelopes didn't even come close to working. Anyhow...would love a Spectrum flight profile for this thing...

I'm using an AR 637T RX and an IX 14 TX so I don't want to send you my programming files as there may be some differences between the 2 transmitters which could cause more harm than good.

With that said, I can give you a few starting points I like, but everyone has their own personal preferences, but keep in mind that I never program in SAFE as I really don't like the way an aircraft flies with it and it makes me feel that I am not in complete control of it's orientation. I have my FM for gains set to my switch C (AUX2) with flying gains at 50/55/60 (I know that sounds high but works for me and I can dial the gains down in flight anytime with my right knob as my gain switch-but never had to), take-off gains at 60/70/80 and landing gains at 70/80/90 with all priorities at 160.

Flaps at take off are deflecting 29 mm with 2% up elevator compensation, while landing flaps are at 50 mm deflection with 4% elevator comp. 3 different D/R & Expos tied to a 3 position switch, ailerons for low/mid/high at 60%/72%/85% deflecting 30mm/36mm/42mm (this will depend on which holes you use in the control horn and your TX), Elevator 85%/100%110% which is 30mm/34mm/36mm, and Rudder at 70%/75%/80% giving 21mm/27mm/29mm. Expo at whatever your personal preference is but I like it relatively high at 20-30%.

Main recommendation I have is not to fly it at the manual 78mm. Way too nose heavy making landings more difficult that could result in a nose first touch and the "dreaded" Bucking Bronco". :face_with_symbols_o I have mine balanced at 92-94mm, which results in extremely easy flying and landing. Don't forget that the jet wash goes directly over the elevators, so if you have it too nose heavy, hence more up elevator trim, the throttle position will affect the attitude much more than with other aircraft causing it to climb at high throttle, and drop at low throttle. At 94mm, once trimmed it will maintain the same attitude no matter what your throttle position is. I'm flying mine on 2 of the new SMC HiV 5900's, each weighing 740gr and have the batteries in line (not stacked on each other) as I removed the circuit board in the back, stuck it to the port side of the fuse, and can position both batteries far enough back to get my desired CG. I'm sure the Avian ESC will also handle HiV batteries if you're so inclined. Flight times are 6-7 minutes and I earlier replaced the old standard 80mm outrunner fans with inrunner fans from my Mig when I upgraded those.

In my option, this is definitely one of the best flying EDF's in my arsenal, takes off smooth, flies exceptionally well, cruises much slower than you'd think and lands like a trainer. You will not be disappointed. Looks Bad A.. in the air as well!!!:a10::a10::a10:
