rustyh17 First, I hope you are recovering from your operation and get well soon!

Go ahead and get your 5 year old son a S-107. I bought one for my grandson for Christmas who just turned 5 a few weeks earlier, and he is still flying it and does very well. He can maneuver it around, though and over practically anything that has a hole wide enough for the blades to fit though. He loves it and I have even had him on the sticks with his dad's 9053. He has his own fixed wing foamie trainer called an EZ Trainer and he can fly it without me touching the sticks though a whole battery pack.

Don't worry about projecting your love of the hobby on your son. Just let him progress at his own speed. I had both my boys flying fixed wing very early (around 2 years old) and they are adults now with their own kids, and they still love flying with their Dad (me ). I never pushed it on them and if they did not want to fly I never forced them to.

In regards to taping the canopy or trying to find a spray coating. Maybe just coating the inside with Welders glue. It if sticks to the plastic, it would work as I use it as a hinge for control surfaces on foamie fixed wing planes and it works great. Very tough and very flexible. I will try it out and let you know. It would be easier to apply then taping.

kdean, thanks for posting the video. Nice flying! I have been flying everyday, but mostly in the back yard hovering and practicing side to side hovering as described in the RADD method of teaching. Sunday morning, flew at the high school over grass and had some good FF flights, not as good as yours, but good for me. After going though a small stock pack and at the end of the large pack, I decided to try nose in hovering and that lasted for about 3.7 seconds (if that) and ended up stripping a screw out of the aileron bracket and that ended the flying session. Funny that I can fly nose in to me, turn around and land with no problem, but when I try to take off nose in to a hover, it is hard. More practice needed. Back home, easy fix and back to hovering.

hey guys,

Just orderd some stuff, and need a little help.

I got a syma s-107 and a set of re-placement blades for my son, he cant wait for it to get here. He is thrilled to be getting a heli that has "spare parts" we can order. I told him that the air hogs, once they are broken, you cant replace the parts. Now he cant wait to put some "spare parts" on his heli.

I also orderd a rx for my 9053, and I had to order the tail boom from Hong Kong, so wont be here for a while.

For my V400s' I orderd some spare CF blades, at 325mm they are longer than the stock main blades, but shou;d work fine. For $8 I have to at least try them. If they are an improvment, I'll let you know. I'm still looking for some good foam blades that will save my head and swash incase of a bad crash.

I also orderd a 1800mah, and a 2200mah blue lipo batteries. I got one each to test them both out, and from what spad says, I dont think I need 14+min of flight time. My hands still shake from nerves while I'm flying, I have to put her down every now and again to regain my composure.

Now, the problem is......

I dont have, and cant find any 4.0 banana connectors. I really only need two 3.5 to 4.0 adapters made up, so that I can use the stock and the blue batteries. I dont want to change the connection on the esc until I have enough batteries w/4.0 banana plugs.

Will someone be willing to make up three short 3.5 banana to 4.0 banana adapters for me, and mail them to my P.O. Box. I will pay for everything + your time, via paypal.

Please let me know. I need these really soon, the blue lipo batteries should be here in one week.

I ordered a pair of 325mm wooden blades on ebay:

http://cgi.ebay.ca/2X-325mm-Wooden-M...item27b8dc0429


It works, good lift but not as smooth as the original as there are always some imperfections on wood.

I've replaced all the stock connectors with these:

Shipping from Hong Kong/China are really slow now. They are cheap if you can wait.

Nice flying Kdean!! I'd help you out on the adapters but I'm out of both 3.5 and 4.0 plugs. In fact, I bought a bunch of XT60's, but still not sure I'm going to swap everything over. The banana plugs are a pain to take apart sometimes. I just ordered a bunch of 4.0 plugs from Heli Direct, for both the Blue Lipo's for the V400, and for the 500 I'm building.
I just heard from my source in China, the V400 is NOT being discontinued, in fact, Walkera has discovered they supposedly have found that tey under estimated theyre materials cost for the V400, and are hiking the prices. We'll see. Supposedly, they will still be readily available. I'm sure parts will go up as well if this is true. Kinda glad I got 4 when they were $149.
Are you flying the brushless upgrade? If not, I've heard they will slow your headspeed down a bit so you may need to adjust your throttle curve...This is second hand info of course.

OK, just ordered the adapters from todd's, and could not help myself, I also ordered 3 hitech 5055 MG servos. There is good reason for this.....

I was flying my #1 today at lunch time and noticed that there was a "glitch" in the alieron servo. It would work fine for a while then just dip all the way down for a second. It was doing this while I was shooting that first video. You can see the heli take a sudden dip to the ground every now a again. I thought it was because of the wind. I just changed that servo, after my first crash, with one of the stock servos that came with the crashed #3. So, I'm gunna open it up tonight, I have a feeling its a................ you guessed it "A STRIPPED GEAR" shocking, I know. I gunna see if I can swap the bad gear for a gear out of the other stripped stock servo, if its a different gear. If not, I'll have to use the other, and last, stock servo that came with #3. This is why I pulled the trigger on the hitechs.

Thanks russ, for the link. If the shipping goes right, I think I'll be using Todd's in the future.

Thanks blayd, Im not going brushless yet, but soon. Once again after buying those servos and the batteries and s-107, my "hobby" account is back to a $0 ballance. Once again my wife will have something to say about it
I'm trying not to fly my #2 until I get the brushless upgrade and put it in that one. Then I can use that brushed motor as a spare (only 3 flights).

Thank you all for the great help. Its like youguys are the V400 A-Team

I'm not flying a brushless motor either, I have like 6 new motors in my spares, so I'll eat them up first. By that time, they will more then likely have the tail brushless as well. Who knows... With 4 of these little suckers, I can keep at least one flying... but now my money is going towards a bigger project, so I'm only buying parts as I need them for the V400's. Not buying up stock like I did before. That and, I'm alot more cautious about my flying, so I'm not crashing as much......LOL. I'm not moving forward that fast either.... but at least i get to fly a bit. Using less parts up.

Lesson Learned

After a couple of crashes when I did not "listen" to my bird when she glitched, I now land and check everything out when that happens. Most of the time, it was a servo that worked loose. This afternoon, I was 1/2 way though the 2200ma pack and over 25ft high when I noticed a glitch, At first I was thinking wind shear (there was a light breeze) when I decided to bring her down in a slow decent when less than a foot above ground, the main motor just stopped and she dropped the rest of the way. After checking all the servos and hardware, everything worked except the main motor. Finally, I found a small circuit board that is part of the electronics from x-helli's brushless system and it's negative wire became detach. I resoldered it and made a strain relief out of electrical tape and put everything back together. I cringe when I think if this had happened when I was flying her that high, It could have done a lot of damage. I have dropped a 9053 from that height more than once with little damage, but we all know how that heli is built compared to the V400.

This also brings to mind about a week ago, after breaking and repairing the tail motor holder several times, I was hovering about 5 ft up when all of a sudden the tail rotor stopped and she when into a spin. I reduced power and actually landed her not too hard with the fuse spinning. I get the feeling, I could have kept her up if I wanted to, it was that stable. Gotta love those gyros! That incident was due to the rear motor wire breaking at the solder joint.

do the wobbaly, wobble

I just got back from the park with my son, flying my #1 and #3, and I'm haveing a wobble issue. #3 (crashed once before I bought it, repaird and installed tgy-90s servos) has a little wobble and I dont know how to get rid of it. It is starting to effect its stability in the air and also seems to drain a battery quicker. When I got it the upper frame was pretty bent, but I just bent it back. The gear had a few teeth shaved down, so I tightened up the mesh. After installing the servos, I tracked the blades. The tracking was a bit of but it is perfect now. How many different things do I have to check. The gear is not warped, I need to check the main shaft, feathering shafts (what are these by the way), the blade holders, bearings, swash plate, what else?

If you have experienced, and fixed, the wobbaly wobbles on your V400 can you please post what the problem was.

I know Blayd can take a head apart with his hands tied behind his back, and standing on one foot.

Thanx Blayd, I did take off the blades and unpuld the tail motor to look at the head and blade grips as they spin. They look fine. I can see the swash move ever so slighty but nothing else is out of line. I can hear the gear making a funny noise every time it goes past the shaved portion. So I think I'm start there.

Do the main shafts bend on this heli? I've been chating with procrasher who makes Stay True Shafts for the V120 and M120's. He says he can make them for the V400 as well (about $30 each min of 3 per order). But, if this shaft is not as weak as the 120's then we have nothing to worry about.

Anyway, my flight count is up to 28 w/ 1 crash, and my confidence on the sticks is improveing. Now to invest in a FPV camera and a Sunglasses SpyCam....

Still trying to decide........
brushless upgrades and spare parts, or M120 w/2801??????????????
