Binary,
I flew last night for the first time with the y harness using 2 turnigy 160's. I had just bought 10 for my other planes as they are dirt cheap(not as good as the hyps but I bought 10 for 18 bucks versus about 85 for 10 hyps). It doesn't have the same output rate as the 2s batteries so you will notice it won't have the vertical it has with the stock battery. But it ran fine otherwise and the run time was good.

The batteries did get noticeably warm. A lot warmer then they have in my other planes.

What kind of run times are people getting with the stock 120? I've been ending up with about 3.5 volts after about a 5 1/2 minute run time.

Is that with mixed throttle setting or WOT?

Mostly mixed. Probably 1/3rd WOT the rest maybe 1/2 to 3/4 throttle.

I usually fly for at least 6-7 mins on the 120. Most of it under 1/2 throttle though.

Even 6-7 minutes is getting too long. The only time I have sunk this plane is when I ran out of juice in a turn lining up for a landing. It doesn't take much to stall when you start running low. I'd suggest setting your timer at 4 minutes then giving yourself a good 30 to 60 seconds to bring her in. Just buy a bunch of batteries and keep swapping them out. It's not worth it to try to squeeze 1 or 2 more minutes out of the battery when this plane falls like a rock without throttle.

the instruction manual says the motor will "pulse" if you hit LVC - that sounds nasty to deal with! although i suppose it's better then the brushed planes that just turn off mid-air.

i haven't hit LVC yet, luckily.

i have my timer set on 5.5 minutes. i land before it ends with the 120s. when using a pair of Hyp 160s, i land after i hear the timer go off

I had hit lvc once on the beast I was bringing it in for a landing(3rd attempt as I had overshot the landing area twice already) and I was about 5 feet off the ground when the power went out. Luckily I was still over grass it nose dived right into the ground. I tried pulling up but I didn't have enough time or speed to get out of it.

The battery cover came off and I popped the end of one set of carbon rods that connected to the bottom wing off. I just need to glue it back.

The beast does NOT like unscheduled landings - it's really heavy in the air for an UM and since it doesn't coast well, you may as well be dropping it on its nose from eye height It's definitely much more fragile than the workhorse UM T-28 or Champ

I think the consensus is LVC is a bit low for optimum battery health too.

Heck on my friends champ before he lost it we could cut the power and the thing would practically glide forever.

The t-28 I could keep the power low and just coast right in. It's taken a hell of a beating but keeps on flying. I'll see if I can take some pictures of it and post them up here. It's ready for a new fuse and a new horizontal stab.

The beast comes in more like a rocket.

I think that I have a finer resolution on my throttle control that I could perfect my landings even more. Right now I feel as if I use up too much room for approach. I can get very nice landings given enough room but I feel like I could dramatically shorten my approach length if I had finer control resolution on the throttle. It just feels like I need a few more increments of speed control when settling in - especially with the Beast as it wants to stall a little easier.

With the Sbach I can largely control my speed through elevator control.

I think I remember reading in the Beast manual that when it hits LVC you need to bring the throttle all the way down before it will let you have some power again (might be wrong). Had to read the PDF version because mine didn't come with any info, same goes for the ar6400lbl receiver.

For smoother throttle remove the ratchet spring like on a heli transmitter.
