Has anyone tried or heard of using any other resistor? I have a bunch at work that are close but not quiet the same. Would be nice to use one o them instead of making a trip to get the 1k.

I have a bunch of non-1k resistors, too. But considering that a new Rx is around $50, more or less, I decided it was worth the trip to the Radio Shack.

As I'm currently still having to plug in my AILE servo after binding with the new rx...

You can sting resistors together in series (end to end) and add their values. Also I would think it doesn't have to be exact, these resistors themselves aren't even that accurate. For example if you sting together two 480 ohm that would work. Whatever gets you between 900 and 1100 ohm I'm sure would be fine

Now I am noticing the main gear is not parallel to the upper frame opening. It is high in the back and low in the front. The gear is high toward the aft end. This makes the pinion appear not to be engaging the main gear at 90 degrees. In order for the main gear to be "off," all those frame holes which hold the bearing blocks, or maybe just the top set, have to be off. Might this be a possibility on all V400's and possibly why the top set of holes are off? It might be a possibility we are just duplicating what is there.

Bravo on a genius grade analysis of the frame dilberto!

I may be loosing my mind and/or eye sight but viewing the aft end of the gear, there is more clearance between it and the lower frame than the forward end.
Hey Jack, I had a similar thing on mine and I'm guessing that walkera doesn't hold very tight tolerances. You do bring up a good point there, if the top bearing block holes don't line up exactly with the original, it might be the original that is off. When I drew it up I made sure the bearing block holes were square and parallel (I don't have my dimensions on me but I think the holes are 25mm between the top block and the bottom, and 12.5mm between the holes of each block). I'll be interested to hear a liitle more info from heli biggie on which holes and how far off they are

Yeah makes sense. I was thinking that, but the resistors I had at work I could not find a combo that would work...
So $1.19 at radio shack later and I got a 5 pack of the 1k in hand.
Does it matter in which direction the resistor goes?

I don't think so. If it does matter, well then I got lucky.

My Bl tail motors show up tomorrow, i went for one more flight today before then. Stock tail motor gave out...I got to about 20 feet saving it with no tail motor, then it just went sideways i couldnt save it.

No polarity,connect the resistor either way.

Oh those damned brushed motors! Sorry to see your heli is such a state, and yes I do know how it feels. Now rebuild it better than ever.

That's a bummer and bad timing being right before your bl motor shows up, but like Nav said, we've all been there, and you'll have it flying better than before

Already torn apart, oddly enough i have all the spare parts on hand heh. Whats funny is tonight i was taking it apart because the Bl tails show up tomorrow along with the converter to get rid of the stock ESC anyways. BTW that's the same heli i saved from that nose dive yesterday. Theres the parts broken below, add the main gear to that, and the boom was not straight so i did that myself the rest of the way heh. and the feather shaft is toast along with the shaft which was actually very slightly bent.

My question is, the HS-5055MG servos are ok, but the tabs are broken, Do they sell the casing for these? Or do i need to find another way to attach them or just get new ones.

Sorry to hear about this man, I was actually enjoying my v400 stock, then one of the servos stripped out, then I got to reading how bad the brushed motors can be so I decided to shelf mine and wait till I did the brushless upgrade. If my chopper is gonna crash I want it to be my fault haha!!
