Ran up the A60-16m on 10s with a 18x10 apc and got 55 amps/2100 watts. I will probably go with a 19x12, should boost the watts and still keep the amp draw ok. I am using an HV-85, its mounted in the air stream from the bottom of the cowling cut out. I dremeled a nice big hole in the firewall inline with the cut out on the cowling and opened up an exit hole on one of the black stripes on the fuse so its not that noticeable. Waiting on the Dave brown spinner and prop. I will try to get some taxi testing done tomorrow if the weather holds up!

19X12 is a big jump. The ESC should hold up but the A60-16M may be way over it's 2200 Watt spec. I know we run the Hackers "hot", but be careful.

I should talk. I run my A50-16L rated at 1850 Watts at 2200 watts...

Should be alright Jim, my target would be 75 amps, which will unload a little in the air. Hacker under specs there motors, I run my a60-18l at 4000 watts, and it is fine with good cooling. Mustangs usually dont get the best cooling with a huge spinner up front, but I will have good air flow thru the cowling and fuse. I am also changing out the flap servos, wanted to use something with more torque since its turning out to be a heavy weight. I am guessing 15 1/2 lbs. whenits all done..

Definitely. At 15+ lbs your going to need all 2800 or so watts.

She is going to kick butt.

Wow, 15.5 lbs = 40 oz/sq ft wing loading!

Should be good with flaps though huh?

Hi Mike, I am building one of these too at this very moment. So far, I just cut the cups out for the retracts, and the plastic is pure garbage. It is extremely brittle and my first plan was to use scissors, but it cracked all over the place. An X-Acto was next, and no better. The Dremel was the only option and even that was slow going.

Sorry to drone on, but my real question is this... where did you put the tank for the retracts? The instructions don't ever mention or show what to do. It appears that you are putting it in the fuse, which makes sense, but I was hoping it would fit in the wings someplace. Where do you plan to place it?

By the way, thanks for putting your build online.

I put mine just behind the rear former in the fuse cavity. Under the pull pull tubes I put some velcro and I added a wood former to keep it from moving around in flight. The plastic is real brittle, try soaking it in warm water before cutting it.

Thanks for the great info and photos! I know you are going electric, though I am going to stay with a nitro version. The box shows a YS 1.20 and the they recommend a 1.20, but with a weight of 15 lbs, I wonder if that will be enough. Now I am a bit worried. The retracts are very heavy, the wings weigh a ton by themselves, and the fuse is pretty heavy too. This might get interesting really quickly. Now I am kicking myself for selling a brand new Saito 1.80...

Tonight I swapped the pull pull wires on the elevator for some thicker wire. The wire that came with the kit was real thin and was supposed to be doubled up. I would rather use thicker wire, especially on the elevator. If that were to fail the plane is done. The rudder seems ok, if it were to loosen up it probably would still be flyable. I will probably change that also. Replaced the flap servos, the way the flaps are designed is unusual, cause the hinges are on the bottom of the wing. The bolts supplied with the kit should have been longer, for the ailerons they were fine, but the flaps are much thicker. I may switch to longer bolts. Just waiting on my spinner and prop, hopefully a maiden soon.
