PJ, when you get to installing the DA85, let me know, I have a sollution for the choke. (always a pain on the DA85) I'll send it to you for free if it looks like it will work john

RE: Extreme Flight 87
Mine is still in service, I had to do a little rebuild as well, it has hundreds of flights on it. Weight is 14.75 pounds w/o the wheel pants. My Buddie JRV has a new one in the box and he's putting it together this winter, lucky guy! The 87'' is the origional Yak Hot Rod. I sure wish EF would build this plane again.

RE: Extreme Flight 87
I never had any issues with it snaping on full elevator imputs, oh maybe once. The plane is probably a little less stable for IMAC but for 3D I think it's a dream. It responds to all imputs quicker than the 88 inch. LOts of guys love the 88 inch, most of them never had the 87. The 87'' became sort of a unpopular (to put it nicely) after the 88 came out. Needless to say this had to be done in order to promote and market the 88 inch. I'll try to sum it up. the 87 inch is lite, nimble, wippy, with a higher power to weight ratio. The 88 is smooth and stable. (most love this, I don't) If your not going to buy the 87 please send me a personal message, I'd love to look it at.

RE: Total lock out on JR12 2.4Ghz
Dennis, until 2 months ago, I was saying the same thing. I just could not believe all these stories about JR locking out, or coming unbound. Then it happened, my reciever unbound in flight. Its a bad feeling to say the least when your plan is flying away and you can't do anything about it. Remember one thing. Not one single JR/Spectrum user had any trouble until the day they did.

[quote]ORIGINAL: Socomon From a Spektrum manual:   <font size=''1''> 4. Q: Sometimes my receiver loses its bind and won’t connect requiring rebinding. What happens if the bind is lost in flight?   <font size=''1'' face=''Helvetica LT Std Cond Light,Helvetica LT Std Cond Light''><font size=''1'' face=''Helvetica LT Std Cond Light,Helvetica LT Std Cond Light''><p style=''margin-left: 40px''>A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand that during the binding process the receiver not only learns the GUID (code) of the transmitter but the transmitter learns and stores the type of receiver that it’s bound to. If the transmitter is placed into bind mode, the transmitter looks for the binding protocol signal from a receiver. If no signal is present, the transmitter no longer has the correct information to connect to a specific receiver and in essence the transmitter has been ''unbound'' from the receiver. We’ve had several DX7 customers that use transmitter stands or trays that unknowingly depress the bind button and the system is then turned on losing the necessary information to allow the connection to take place. We’ve also had DX7 customers that didn’t fully understand the range test process and pushed the bind button before turning on the transmitter also causing the system to ''lose its bind.''

I did a range check previous to this incident, my data didn't even come close to what was considered no-go. All data was totally acceptable. I just wish I had taken the data after the crash before I powered the system down, it was right there for the taking.

RE: Total lock out on JR12 2.4Ghz
I lost a 33% Yak yesterday. first flight of the day. Using a 4800 Fromeco on the receiver, deans connectors into a smartfly regulator with a fail safe switch. Two power leads from the smartfly regulator plugged into both data ports on the JR921 2.4 receiver. Transmitter is a JR 9303. The plan was flying straight and level at about 200 feet 3/4 throttle. The plane made a quick up/down maneuver with the wings level, at that point I had no control, the plane flew straight away wings level and descended until straight vertical into the ground. Failsafe was set to last command, engine to idle. Crash site investigation found the servo's to the ailerons, rudder and elevator still buzzing with power, but would not accept any commands from the transmitter. Continuity was established for all control surfaces. Post crash receiver battery tested at 7.65 volts under a 1 amp load. I should have taken my data log to the crash site and taken the receiver data before the system was powered down, but in my haste failed to do this. I then rebound the receiver and everything works fine again. The plane is a total loss however. my receiver came unbound, If I had lost signal, the receiver would have gone into failsafe and the engine to idle, the engine remained at the same 3/4 power setting all the way to the ground. I always thought these 2.4 plane crashes were guys that didn't know how to fly and were making excuses for their crashes. Now I know the Spectrum 2.4 has issues. I had 4 witnesses watching, they all saw and heard the same thing. I would never fly 2.4 on a large plane again without redundant batteries and receivers. john UPDATE..... My throttle servo was within 4 inches of the ignition. I was under the belief that with 2.4 this was OK, now I have learned it is not. Possibly this was my problem and not the fact that I'm running a 2.4 system

RE: Aviation Models 33% Yak Build Thread
The reason I didn't put the can in, is because I would have had to cut the bottom of the firewall away or hack up the tunnel just to get the can in. The tunnel is large enough to slide the can straight in, but not at an angle. Anybody installing the MTW110k can would want to do this before the firewall is glued in place, and then hope they never need to remove it. The MTW110K can is the correct canister for the DA-85. I'm not sure what the other engines use, a narrower canister would go in without any trouble. john

RE: Aviation Models 33% Yak Build Thread
[quote]ORIGINAL: Flyinhi1 I hope so, like I said though, mine didn't give me any indication ever, that something was wrong - - no loose muffler, no broken joints in the airframe from excessive vibration, started easily every time, no dead sticks , great power......I was sure I was going to be the exception to to what I'd been hearing for some time about this engine. Then boom! (actually - abrupt silence) and too low and slow to do much of anything except roll upright (I was inverted at the time) and pull full high rate elev. to flatten her out for the inevitable drop. Plopped down nearly perfectly on all three wheels, broke just the tip off one blade of the mezjlik prop, broke the spark plug in two and split the plug boot. Slightly bent the outer corner of the head cooling fin and gound in some surface asphalt from the runway to a couple other high spots around the bent fin. Pretty much a direct impact to only the top of the engine. Almost didn't even think it needed to go back to DA, but since I needed them to fix the ignition plug boot I brought the engine along with me down to DA just to see if they could do a quick check. A few days later I called to see if it was ready and they said the crank had been pushed back into the case and they had done all this work to it. I'm fine with it that they did it, but it sure didn't seem like that crash would produce the damage they said they found. I know I've pounded my 50 in a lot harder than that and never took it for a check up and it runs damn good and smooth. Just lucky there I guess, no? [/quote] Hows the 85 running now?

[quote]ORIGINAL: Flyinhi1 Hey guys, just found this thread. I'm Dave's friend with the injured Suk.....DA did indeed do the carb spacer, mid and front bearings, shim, c-clips, piston, ring, steel bolts,etc. Basically have a nearly new 85 again. Not sure what to think about all this since I have papers from when I took it for known upgrades around this time last year. Never started it until June-July of this year. Hope your on to something John if it was an air leak. Also, even though I didn't think it was that bad to begin with, if the newer piston helps with any vibration issues, that's just icing on the cake. I've got to wait til after the Shootout to be able to fly this plane again, so we'll see how it all goes. Like my name says, I'll be Flyin High until I get comfortable with this engine for a while. Never had any problems keeping it turning until this happened. [/quote] Sounds like they did the exact work to your engine as they did to mine. Your going to be very happy with the decrease in vibration! My muffler doesn't come loose anymore. I know how you feel about flying high. Before the upgrade I never made a landing with the engine running. I had to fly high enought assuming every landing was a deadstick. After the upgrade it has never quite. I'm down on the deck again! Now I love this motor. I should have called DA right away, rather than waiting 3 months.
