LOL! Now, that would have been priceless!

The rod from the servo that controls the elevator flexes instead of simply pushing. Recently the rod slid out of position on the control horn while flying and caused a crash. After that I CA'd it to the control horn. Is that what is causing the flex? How do I get rid of the flex while preventing a repeat of it slipping out of position?

Also the servo itself seems to have a limited range of motion in compared to the rudder servo that is next to it. The elevator servo doesn't move much at all while pulling the control rod(down elevator). Thanks for any help.

Tried the 3000kv in the beast today,

Huge power boost!

Don't need no 3s!

I'd guess the pushrod is most likely binding on the foam somewhere. It shouldn't flex very much at all.

Where do you guys buy gws 5030 props? All I find are either orange or three blade.

RCBabbel sells them. Also - All e RC used to have the black props available, even though their site shows the orange ones.

BTW - Brian's testing showed that the 3000Kv/5030 combo on 2s produces about the same power as the 2300Kv/5043 on 2s. The 3000Kv/5030 has a slight edge in raw thrust, while the 2300Kv/5043 has a slight edge in speed. Both combos easily outperform the 2500Kv motor with either prop in terms of thrust and speed. However, the 2500Kv/5030, 2300Kv/5043, and 3000Kv/5030 on 3s are by far the best performers - plus you get longer flight-times on 3s. See my static RPM data, below.

Interestingly, there is little difference in static thrust between the two combos, however the 2300/5043 combo's pitch-speed is nearly 20% higher. It's also interesting that the 2500/5030 actually outperforms the 2300/5043 in terms of thrust on 3s, considering that the 2300/5043 produces more thrust on 2s than the 2500 with either prop.

RPM taken under natural light with a calibrated optical tach, 30 sec into each run on a freshly-charged pack:

Pack: Hyp 180 25c 3s
Elevation: 910 ft AMSL
Temp: 70 F

Motor/prop ---- RPM -- Thrust (g)* -- Speed (MPH)**

2300Kv/5043 - 10,700 ---- 159 ------------ 43.6
2500Kv/5030 - 12,870 ---- 164 ------------ 36.6

For reference, here's the 2s data with the stock motor:

Motor: 2500Kv
Elevation: 910 ft AMSL
Temp: 70 F

------------- Hyp 240 - TP 325 65c - Hyp 500 35c - Thrust (g)* ---- Speed (MPH)**

Stock prop - 10,550 ---- 10,770 -------- 11,100 ----- 99/103/110 --- 27.5/28/28.9
GWS 5030 - 11,010 ---- 11,160 -------- 11,340 --- 118/121/125 -- 31.3/31.7/32.2
GWS 5043 -- 8,910 ------ 9,040 --------- 9,210 ---- 108/112/116 -- 36.2/36.8/37.5

*Calculated using the GWS prop spreadsheet
**Calculated pitch-speed. Prop slippage and in-flight unloading not taken into account.

Yes, you're right, you get more power!

But:
You also get less flight time!

With 3S you get even more power AND MORE flight time.

I'm converting my beast to 3S at the moment.
Still testing, but it looks really good.

I will post rpm, thrust, current, flight time and other details in one or two days, when conversion and testing is done.
edit:
I will measure each value, just calculating will only give artificial and maybe false information.

www.gwsprops.com when you order add a note that you want black. They usually only stock black and grey so even if you done get black at least it wont be orange!

My 3000kv/5030 handles 3S just fine as well. now THERE is a massive power combo!!

I agree here. I found that on my Beast with the 3000kv motor I'll fly on 2S and not reaching for the 3S packs. I think this is because of the added thrust this combo has. With the 2300/5043 I could not arrest the descent in a blender even at full throttle on 2S, with the 3000+5030 I can. Granted you wont have the blistering 45mph level speed that 3S gets you but it is still really fast. Couple that with a much lighter BB240 2S pack and you get a really nice light plane as well.

I paint my orange props with chrome spray paint. Looks like the real thing and shows up well in the air.

Gord.

Chrome paint? Sounds interesting! Could you post a picture?

Don't have a pic right now and the plane is out in the van, but here is a pic of a wood Topflite prop on another plane. Proper name for it is Chrome Bumper paint, picked up at the local auto parts store. Comes in spray bomb of course. Very high pigment so one light coat is plenty.

Sounds great! Are you using the stock electronics, and which packs are you using? Over the past 3-4 years, I've done a fair amount of RPM & thrust testing on the UMs with various props & batteries. My static test results correlate very well with flight-test results. The only thing I'm missing is current & voltage, as I'm not set up to accurately measure these low currents. I'm also rather shy on 3s test data. I look forward to comparing our results!

I didn't know that you're running 3s with that combo! (I updated my post.) Bet she wails like a banshee at WOT! Have you measured the static RPM on that monster?

Flew the Beast yesterday with 180mah 3s NanoTechs for the first time.
Wow! So much more zip. Lots of 15mph wind but no problem for the Beast.
The only problem I had was flying it with a TP325 2s for 5 wonderful minutes and then getting swallowed by a tall and scraggly Black Locust tree in my yard.
Wings got busted and guy wires tangled in the branches. No amount of shaking would bring her down and only seemed to tangle here even more.
It's supposed to rain buckets tonight and I'm fearing I'm going to need to write her off.
Too bad. My Beast was the most prestine of all of my planes and the only one that I actually stored in the original box to keep it that way.
Lost the plane and the $20 battery.
Waaaaahhhh.

do you have a long pole? straighten a wire coat hanger shoulder curves but leave the hook, duct tape it to the pole, and try to hook onto it to pull it down, unless it's hundreds of feet in the air
