Sale price is 200.! Don't know if you can get additional discounts or not, but at that price I may have to put one up on a shelf somewhere?

It should still qualify for the Super Saver Club discount. I'm not sure what the discount is for $200.

Hi WJ
it is a DA 170
it is a thirsty monster!! LOL
i figured out what happened:
now that i think about it, i had fueled her up. Then i turned on engine, played with her, tuning her, several times. then i figured out the idle stop screw was the problem, then i turned her on again, played with throttle curve on transmitter, then i turned her off, saw someone else fly, then i took her up. forgot to refuel her. i checked afterwards for gas in fuselage, but it was dry throughout.

Ortho:
The engine is a DA-100?
One might expect fuel consuption of about 2 oz / min / 50cc, or 4 oz/min if i remember your engine right, which should give you 13 min at WOT.

It sounds like you are using twice that. I might check for leaks. Or maybe i am misremembering the engine; if it is a 200-220, might be about right.

Hi ortho
So your fuel consumption pretty much lines up. Lucky you on the nearly dry tank, but at least you know that you do not have a leak to deal with.

I was out with my R90 again today; what a beautiful bird. She flew well in 10mph north winds. Still taking it easy on the new engine, but may be able to start wrining her out a bit next flights. The DLE55RA with its 'muffler' is pretty loud, but i think i have a muffler mod that works pretty well to quiet the bark. If i become convinced over the next week or so, i'll post the mod.

High rate aileron rolls at at least 720*/sec, probably higher. Very axial. No snaps or flat spins yet, but she did a pretty hammerhead.

My R70 hit 98.4mph by GPS the other day. I was not actually doing full speed runs, just flying around getting some data into the EagleTree recorder. The recorder actually reads the tachometer lead from the ignition, and the rpm measured corresponds pretty well to my measured speed on the 12 pitch prop. I will post more specific data as they accumulate.

I pulled 4g in several maneuvers (loops, et), and 6.1g in another (hard turn), so I'm beginning to get a sense of the forces on the airframe. I did not push her hard on this flight, so what we do to our airframes may be quite a bit more intense than we think.

I am pretty impressed with Eagle Tree; i set the instruments up on a board that i can swap from plane to plane. it was hardest to stuff into the R70; will fit fine into my larger birds.

As long as we're talking about other planes, I was re-maidening my H9 P51 150 \ MVVS 35 this morning at a field right on the water on the south shore of Long Island (Hecksher State Park in Islip) (a new club I just joined). This runway is right on the bay, and just south of it is a beachfront woods - lots of thick tress with pine cones, tall grass. Some trees are 30-40 feet high, many are 10-20 ft. Lots of thick bushes. Got the plane up in the air - engine sounded great, had just trimmed it out, about two big loops around the field. The 51 was just turning right to come back from a deep downleg when I lost control of it - seemed like the elevator was not responding. Went down at about 2/3 throttle, at a steep angle - about 200 yard (a guess) into the woods.

Well, my friend, my son and I search for 4 hours for it and saw no sign of it. We searched what we thought was the entire probable area over and over. Problem is this brush is so thick you can't be sure if you've looked into each bush - and it all looks the same after a few hours. Had to abandon the search when the freezing rain started (perfect!) It's bad enough that I crashed it, but to not find it at all is extremely frustrating. My friend has offered to go back again tomorrow to continue searching. Guess we'll expand the search area even more. Wish me luck - I really want my plane back - at least to recover as much as possible, and also to try and diagnose what happened.

Mike
Sorry to hear of the loss of your P51!

In any plane i think MIGHT be lost, i put one of these:
http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXSZ87&P=ML

When transmitter signal is lost, it emits an annoying repeating beep that allows you to hone in on it in dense underbrush. That does not help you now, of course.

lop -
here is the website for Eagle Tree systems

microdon2,
I know how you feel.

Last year I had a plane to go down in some very thick tress and bushes. My club members and I look for 2 days but could not find it. About three months later I get a call from some logger doing some clear cutting not far from my club field, that they found what was left of my plane. They took me to the spot where they found the plane, now I know why its so hard to find a full scale airplane when they go down in no man land!!!
I hope you find it!!!

wjc - I never anticipated not being able to FIND a downed plane, but going forward I think I WILL be installing those Air Alerts in each plane. Thanks.

ahicks \ jet22 - thanks for the thoughts. We'll hit the field again tomorrow at10am. I'm hoping for better luck!

hey lop flyer,

i just ordered this today, and it will arrive friday.

i use Jr transmitter, not with telemetry.

1. spektrum TM 1000 DSMX full range module. This gadget fits in your plane. it hooks to your receiver. it, itself has an antenna, and it will transmit a signal somewhere (tell you soon). it comes with 2 sensors. one sensor is a temp sensor for an engine (gas,glow,or electric). the other sensor is for battery pack power level. the sensors connect into the module.

2. Spektrum STI telemetry interface. this plugs into your i-pod, i-phone, or i-pad. once your airplane module is connected as well as this, you do a bind, to connect all 3. (you need to go to ipod store and search , i forgot, either spectrum or telemetry). once you download, you will see something very cool. it looks like an instrument panel on your iphone. if you press one of the gauges, it will say out load, what it is (more on that soon).

3. Spektrum Aircraft GPS sensor. this will collect ground speed, altitude, pressure, direction.

4. Spektrum RPM sensor.

so i connect all this up, go to flying field, and attach earpiece from my iphone to my ear. you can then program for it to relay this info on a 1 minute interval or so. it will say: RPM is ....., head temperature is ........, altitude is .........., ground speed is .........., pack voltage is ........

you gotta check this out.

Hi Microdon, i feel so bad to hear that. i too lost my P51, blue nose, but it was on its maiden flight. i fly out in wide open area, over farmland. Sosorry again.

lop-
The ET system is a way cool toy; you can buy the sensors that you are most interested in having - accelerometers, altimiters, true airspeed (pitot tube), gps, engine head temp, etc. The GPS updates 10/second, so the track and speed are pretty accurate for aircraft. A lot of the inexpensive gps devices out there update only once a second, so speed and position, although adequate for walking/hiking, or perhaps even for a car, are pretty crude for an aircraft.

I drove it around in my truck a few days to check its operation; you can play the track back in google earth to see where you have been driving or flying. The ET system has software to view parameters also - both 2D and 3D graphing capabilties.

My instrument package, all up, weighs <3oz. I draw power from an aileron lead so there is no additional battery.

Mike - best wishes for success. At least at this time of year in NY, you won't have to worry about snakes in the brush, which is always a mental hazard down here.

Just a quick thought on the locators? They work only if the electrical systems stays intact! In a more "unfortunate" crash, many times the battery, being one of the heavier objects in a plane, can be found only after searching a while? No battery, no noise coming from the locator...

ahicks - I thought of that, that batteries and leads can get pulled apart in a bad crash - but its' better than nothing. And for $16 it's worth it.

wjc - thanks. Funny - I was wondering about animals \ critters as we trudged through this stuff. Only ones we saw were a few bunnies and a squirrel. Did see 4 young deer on the road driving in, right near the field. Nice to see that. (though the thought of someone shooting one of those beautiful animals always bugs me...)

You are exactly right, although empirically, in the crashes my birds have suffered, there has only been one time that the electrical system has actually become disconnected; denominator on that number is more than 10; i did not search my flight log to get a better number - too disheartening

Dry fit of Sbach repairs looks good. I included a close up pic of the landing gear and the inner fuse. If you look closely you will notice that the landing gear L-bracket is part of the inner fuse. You need to replace the entire inner fuse to properly fix it. Nail polish remover (ie acetone) has been my friend!

Sbach pics on Facebook

Image upload tool wasn't working so I posted the pics on the Facebook page for my club.

Went back to look for the P51 today - and we found it! Was out WAY further than we thought - by maybe another 800 ft! And just missed going into the bay by about 75 ft. Plane went in nose first - at 2/3 throttle - and pretty much exploded on impact. No rebuild this time. At least we found it and I'm working on recovering what I can. And I can give it a proper burial. Am just about to clean the engine and test it.

Also pretty sure I found the cause. All channels in the receiver were populated except one - channel 2. Which syncs with my experience - that I lost elevator controls. So I think what happened was that, probably because of the mass of cables needed inside this plane (elevators, ailerons, flaps, retracts, etc) I think when I pushed them into the cavity as I was closing the wing I might have tugged on the elevator cable. But it was still in enough to take off and fly around for two laps, before it pulled out completely. My friend just told me that he tie-wraps all receiver cables together just above the receiver to prevent this - a great idea! Now I'll be doing that to all my planes. Just another expensive lesson.

I tried to post some pics (pretty graphic!) but am getting a server error. Will try again later.

Problem now is - I've got the warbird bug!! One thing I just noticed - a new H9 P51 150 (80") is $649, but a Top Flight P51 (84") on TH is $520 Anyone know why the price difference? Are H9 planes overpriced? Or better quality than Top Flight?

On the other hand, a Rev 90 is cheaper than both. Wonder if I could put retracts on it. I seem to now HAVE a spare set...

Hi Mike
Glad you found the 'expensive stuff', and hope it still usable.

I learned that trick from guys in my club - to put a zip tie around all of the cables just above the receiver. Either they all stay in, or they all come out.

I'm told the $2K AW P51 is worth the $$. I have seen one at our club and she is a beautiful bird. No experience with either the H9 or the TF.

microdon2;
Happy to hear you found your P-51!!! When I lost my Blue Nose P-51 and they was out of stock for a long time, I went with this Top Flite ARF, ( see link below, ) and I must say it is a sweet flyer!!
http://www3.towerhobbies.com/cgi-bin/wti0001p?&P=SM&I=LXTDF5
Now if you want to stay with H9, look at their Spitfire ARF. Another beautiful fly war-bird. Go to the war-bird forum here at RCU and you will find build thread and tons of info on war-bird.
Again, happy you found your bird!!!
BTW: My vote is for the R90!!
