I can't help you with the 4 flapped version, at least not in Europe to avoid possible import costs, but the 2 servo wing is available from here with free shipping to the UK http://shop.lindinger.at/product_inf...ducts_id=72487

and here (but out of stock) http://www.modellhobby.de/Models/Mod...=20973&p=20973

and the horribly coloured V2 here http://www.modellhobby.de/Models/Mod...=20973&p=20973 also with free shipping.

Testing the Hawk F5B

Guess what...?? There's a new, lighter and smaller "Cheapo" in town. Have flown it with my X-plane a few times, and it's great! Too small prop for the Hawk, but for the F5D size planes it's kicking butt bit still gives 40sec motor time on a 4S2200.

I finally got around to trying my Hawk out on 5s. I managed to squeeze a TP 2700Mah 5s into it although it's a pretty tight fit. The extra cell sure makes a difference in power and speed.

JDMiller, very nice video and good flying, she really moves on fast and tracks nice.

I see you have the YEP 150A esc, did you do the mod ? to keep it safe..

What is you CG @? And does the break on the YEP esc work ok?

Geez I'm getting worried with all this YEP 150A talk... (I have x2 sitting here)...seriously thinking of throwing them out and saving up for a couple of ice lite 200A esc's....surely they're hold up to 120-160A flying....

blitzu, YEP 150A after the mod tested by at least 3 of us, cool and running nice even at Higher amps, as long as you do the mod there should not be any problems more then other esc:s...

Ok cheers Sebbe
I take it you use the 750uf caps?
Same as whats in it already, but they're Panasonic fm caps...
I read your thread on the mods too.Excellent clear instructions-thankyou

Caps size dont matter * ,

* use FM caps from panasonic, and you have the best to keep the ripple down, they are so low in ESR value so dont matter even if you use one instead of 4 cheap ones..

Bigger better, but down overdo it ,,, I would say at least 470uF x 2, thats what original,, but better is to go even bigger or more caps...
also choose the higher voltage series, I think it was 50V ones I used..

57sailplane, the wires extra is for keeping the distrubition of current equal on both boards(fets) of the esc, otherwise one side will get hotter, not good at all.. You dont have to run full length wires, you can make an Y-connection 1 inch after, this way the current will split 50/50 anyway...

Also do the cable mod on both battery side AND motor side, this way you get more even flow...

With this mods the esc run much cooler, keep up guys...

I have a Hawk copy, the Inertia from HK. Even though it only puts out 2200w on 5s, it's a hoot, and has been very reliable!

That being said, I have stripped out the threads that hold on the horizontal stab. Is there a good source for threaded inserts, and can anybody tell me what size they are? I suspect they are 3mm or 3.5 mm.

Thanks in advance,
