I don't believe there would be a huge power difference. With the lower KV (910) you will get less amps/heat with a given prop. The bigger prop disk gives you better thrust. It's a personal choice really.

Default First flights with 480 910kz MUS

I tried several props but the big suprise was the APC or E-flite
10X7 slow fly props,this thing is a missle with this prop,I want to purchase a 11X7 slow fly on saturday and test fly it.The slow fly props where
faster than the APC E props.They simply move more air faster.I even tried
a APC 11X7 and it was not near as fast as the 10X7 slow fly.What
are others finding out ???

Be sure and keep an eye on your amps. SF props draw a lot more amps then APCE props.

Cool props

I've been using an apc 11x7, and they also have a 11x8.5 A friend of mine uses 11x8.5, and he's convinced me to switch. I haven't got one yet, but whilst your picking up props, you might pick up an 8.5 too, if nothing else, just to try it. I have the 910Kv motor, and am using PQ2200 and TP2100 batteries (mostly) and my current draw has been resonable. I checked it shortly after building it, and if I remember right, I was under 28A at startup, and within 10 Sec, was down to 24 (WOT). I don't fly alot at WOT. The durn thing is ballistic at that speed (But lots-0-fun)

Default Went flying today first time at a public field

I got invited to go flying today and when I arrived it was a paved private runway
about 30' wide and 1/4mi long this was the first time I flew with a group.They all
had glow planes and just kind of looked at me funny when I got my MP and
MUS out and set them by the runway,while they where fueling up I first flew
the MUS and they could not believe an electric could preform like it did.
With the 480 motor and 10X7 prop it was by far one of the fastest planes
there.I then got out the MP after they made a few glow runs,it was only 42
degrees outside and some planes had a hard time getting started and
running right.The glow planes needed a good run before they took off
I set the MP down hit the throttle pulled back on the stick and I bet it was
in the air in less than three feet and then almost straight up.The reaction from
the other pilots was unbelieveable they could not stop commenting on these
electric planes and asked me alot of questions about motors,batteries
and how I could fly so long with so much performance,they just shook
there heads in disbelief.

Other than adding weight to the front of plane to balance is there anything wrong with mounting the eflite 450 outrunner on the inside of the firewall?

Thanks

Thanks, so would you recommend installing it on the outside as opposed to the inside?

Yes, It will run cooler and will actually be easier to mount as the whole front mounting ply comes off.

I ran mine with a Axi 2808/24 mounted on the inside without any heat issues.

Thumbs up

I took out the 25A esc and installed a 40a e flite ESC and it
made a big difference in power with the bigger props.I guess
the motor was not getting enough amps with the 25a ESC.
I am using a 480/910 Outrunner and this thing rips,you can
actually hear it wizzing through the air when it goes by.
I also ordered a 480/1020 for MUS #1.I am using a E flite
11X7E prop,the 10X7 slo fly really works good too.I also
noticed a little more power when I switched to the TP
pro lite packs over the 1800 PQ.What prop sizes are
you guys using???

bzizzi,

I'm using a similar setup to yours:
e-flite 40a ESC
e-flite park 480/1020Kv
APC 11x7E prop
DN-Power 2100mAh 3s Lipo

Unlimited vertical and sounds pretty cool when flying full out.

I love the setup!

He protested, insisting that he could use the throttle lock, but it's my fingers, so I didn't listen and pulled it off anyway. Sure enough, after a few seconds, when the plane was in my lap, he accidentally bumps the throttle and the thing starts screaming. Good thing there was no prop on it or I would be talking in a squeaky voice right now.

You can have all sorts of safeguards, but knowing that prop can bite you at any time is probably the best one. Don't trust your friends and don't trust the equipment. Trust you because if it goes wrong, you're the one who is going to have to live with it.
Certainly don't trust the throttle lock. Mistakes can happen.

There was a guy at the LHS yesterday buying a 10 outrunner
for the MUS,wonder how he made out ??? I always wondered how dangerous these ultra fast high powered props would be,thanks for
sharing this with us.I will think twice before playing around with
setups without removing the prop again.I have been real lucky so far.
I had my arm wrapped around my MUS one day and bumped the throttle
but luckily the ESC was not armed yet or I would have gotten a real close shave !!! The prop was real close to my face.

Hi
I have MUS on order that I'm going fit with the Park 480.
Can someone tell me when they say an APC 11 x 7, do they mean the APC Thin Electric or the Slow Fly APC?
Really looking forward to this plane-sounds amazing.

Hi Guys,

I have built my MUS and am just doing some final tuning and getting my hours up on the flight sim before I take her out. I just had one question which has to do with flaps.

I have set up my plane to use flaperons, they work fine but when I switch them on I noticed that one aileron travels further than the other. I checked the throws of both ailerons by themselves and they travel the same. I checked their position at neutral and they are level and equal. Can anyone shed some light?

Thanks

Just got mine today..PNP...450 and stock prop...I guess I'll assemble it this evening or tomorrow..I like the looks of the model....seems to be fairly well put together, and with the constant chord wing should be REALLY safe....we'll see how it compares to my Brio 10 which is powered by the 480 outrunner. I have both 1400 and 2200 mah 20C packs for her.
I got it because I want a throw around model just for " fun" ...the Brio flies like a dream...hope this one does too.

I'm using an APC 11x7E (electric). It seems to work great!

Thanks, 11 x 7E it will be then.
Now I have to decide on batteries. TP 2100 Prolites seem popular.
Hopefully she will balance correctly with this pack.

I've had good luck with these so far:

and you get two for the price of one TP2100.

There's a discussion about cheaper lipos here:

Couple things I noticed on the PNP version......
motor needed to be turned 90 degrees so that the wiring is out of the way when you install batteries.

all control linkages had to be taken apart so that I could clean the hinge gaps to make the surfaces easy to move, and I needed to take out the control rods for the tail surfaces and ream out and lubricate the tubes to make the rods slide freely...rudder servo would not center properly till I loosened up the rudder....in order to make it balance I had to have the battery as far rearward as possible... This all took about two hours to do.
I guess you could just add battery and fly, but not without some issues.
I'm ready for maiden , but the weatherman sent us some snow last night, and I guess I'll have to either wait till it's gone or build some skis.

So on to the MUS and a couple beginner style mistakes. The big error was underestimating what the 480 engine would do. I stupidly hit full throttle on takeoff. My second error was having the ailerons on high rates (forgot to check). I was completely unprepared for the rapid acceleration and aileron response and caught a wing after some wild wobbles.

My fuse was destroyed. The wing had minor damage easily repaird with balsa and CA. I have a replacement fuse but haven't had time to reassemble.

I'm hopeful I can fly it OK with the lessons learned.

Sounds like my first outting with the MUS. I didn't have low rates or any expo programmed in and seriously underestimated how much power this thing had. My flight lasted all of maybe 20 seconds before I buried it in the ground. I'm getting it all back together now.

How does your MUS fly with the E-flite 450 and 10x5E prop compared to the stock 10x7 SF? I thought mine was horrendously fast with the "slow fly" prop (Yeah, yeah, I know - learn throttle management! ) but after reading some of the posts in this thread, I'm getting totally confused about props. I would think a smaller prop with less pitch would slow things down a bit but now I'm not sure. In bench testing, the 10x5E seems to pull just as hard as the 10x7SF but the motor sounds like it revs a bit higher. Anyone want to try to explain to me the fine details of props or maybe just the rough "Cliff Notes" version?

Anyway, can't wait to get the MUS back together for "round 2".

Gary.

We bought one of these little beauties for our Micro Skydiver drop plane. We have taken up 20oz. of skydivers on it with no problems. This little plane is worth its weight in gold. The kit is simply amazing in how fast you can have it built. We went with the four aileron/flap setup for the "fun" factor. I would recommend this kit to anyone.

20 ounces??? Hmmm, that's more than twice what my video camera weighs. Maybe I can use the MUS for AV. I think I still want to get the Telemaster for AV though. Might make for a little steadier videos.
