Nice flying!! Big difference with the brushless/lipo's. Looks like you have gobs of power...

armycopter, if you raise the trim on your transmitter you can get more throttle. Raise it as high as you can before the motor starts...or raise it all the way up right before take off if you can remember to pull it back down quick to stop the motor if you get in trouble...

ARRRGGGH!!!!

Well the wind got the best of me today. I was flying just fine and had it up about 30 feet. Then a large gust came and just took it. I could hardly see the damn thing. Well I tried to land it but it wasn't pretty. Man the thing just exploded! The frame is broke in 3 places. The boom in bent. The head is a mess. I need to find some parts here somewhere. There is nothing on ebay right now. Maybe I will just buy a barebones and use this one for parts. Oh well. At least I have my 36. Although it is half the helicopter the 37 is.

WOW. This thing is TOTALED! The funny thing is is that it wasnt that hard of a hit. I hit the ground level, but at a high enough sink rate for the blades to hit the boom. I would say that about 70% of the parts are broken. This is crazy. My 36 has hit that hard with nowhere near that much damage.

I might order a new barebones or just scrap the whole thing and get a nice t-rex. Well see....

Man that sucks. Maybe you could order a metal frame for it... Is the 60 frame the same? Of course if 70% of the aircraft is totaled, there's not much use rebuilding it. I saw that the guy I ordered mine from in Texas has the price down to about $121

which is almost $20 cheaper than I bought mine from a week ago!

It was kind of nice having someone else with the same A/C since there doesn't seem to be too many 37 owners. I think you should get another one :-)

I am not sure what I am going to do yet. The thing that is bugging me is how fragile the 37 is. Maybe if I can get a barebones 37 cheap I might try it again. If flies awsome. It just cant handle much damage. I put in my 36 a while back 90 degrees to the ground. I broke about $20 in parts. The surviving parts of this hard landing fill a small plastic bag.

Sorry I cant. I already threw away all the busted parts and put the good ones is a plastic bag. I should have taken a pic, but I was pretty bummed about it and dismantled it immediately.

Can you test that new WK-G006 gyro(if it's not damaged) on your 36 and let us know if the impact effected it's performance? I'm curious to know how durable it is.

I can do that. Unfortunately it will a while before I can do it. I have parts on order for the 36 that get here on Monday so I cant fly it now. Also, I am going out of town today for 10 days. I will try it out when I get back.

I am brand new to the Helis and bought my 37# on line several weeks ago from Hooobby.com. Out of the box I noticed the tail pushrod was disconnected from the plastic tail rotor swivel which was repaired with a dab of epoxy. I ran through several battery charges at low throttle (even lifting a skid on occasion) getting a feel for responses. All was well and stable until the on one occasion the motor just completely quit followed 2 seconds later with full uncontrollable throttle which wasted one main rotor blade and broke one main blade holder arm. That will get your attention and I was lucky for minimal damage. While waiting for replacement parts I was able to repeat the anomaly and determine (with the main rotor blades removed of course) that the motor controller was defective. I replaced it with a 30A controller from my RC airplane, which completely cured the problem. I also had an intermittent V2 left hand collective mixing pot, which I cured by opening the controller and resoldering the pot connections. I have since received and replaced the broken main rotor parts and the machine seems very smooth and controllable clamped to the bench but I am going to have my experienced Raptor friend take it on it's maiden flight. I would love to hear from anyone regarding the flight characteristics. The machine looks to have good design potential but assembly QC is lacking so clamp this buggy down and perform dry runs with safety glasses on. I will post again after the maiden flight hopefully this weekend.

Jim

Hey Jim, did you get your maiden flight this weekend? How did it go? I'm still looking for a lipo battery for mine. It drives me crazy that i have to have it shipped from hong kong to get a decent price....

okay, finally broke down and bought a lipo along with a brushless motor and esc. has anyone ever heard of these motors/esc's?

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6047634335&ssPageName=MERC_VIC_RSCC_Pr4_PcY_BIN_Stores_IT

anyway, that's what I got - good or bad - I figured I couldn't go wrong for the price. It's got to be better than this stock brushed motor setup. I can't barely get out of GE no matter what I do. it's actually kind of disappointing. these heli's shouldn't even be marketed the way they are... instead of 3D, it should say 3 inches (off the ground). hopefully my new setup will make an improvement. I'm not planning to do 3D, I just want a fun flyer.

can anyone recommend pinion size? like I said, I'd like something that will allow me to fly it around the backyard with decent performance and longer battery life...

by the way, anyone else out there in this thread? it was going good until last week!

That combo looks like it should do the job. I'd start with a 10T pinion. Here's a link to a calculator that may help, just select a motor and heli that is the closest match to yours(select a heli with matching main gear size) and it should give you a general idea at what you will be looking at. http://www.e-helis.com/helicalc.php
