Expecting my new blades from helihobby today, & wanted to know what is the best way to mount them. From one of the posts I've read it seems that on top of the mount is the way to go. Does anyone know what size bolts I need to get to go that route? Also getting the high authority tail motor since mine is toasted, does it have to be soldered to the existing wires or is it plug & play? Any suggestions are greatly appreciated.

The maximum effective range of an excuse is zero meters

That size bolts are hard to find. Too small for most hardware stores, too big for watchmakers and eyeglass shops.
I did finally locate exactly what I needed at the last place I usually every look for RC stuff,,,,,,,, my local hobby shop.
First time I have ever found what I wanted or needed there. He didn't have any nuts for them though. I'm basically just using the plastic head as the nut, same as the stock configuration.
I can't remember the specific size, but if you take your head screw and blades with you, you can check it out. Also, remember to get the bolts long enough to accommodate a head stiffener that you may want to install as well.

If you are talking about the high authority tail motor from Helihobby, which I'm sure you are, it is a bare bones deal, you'll have to take everything off your old motor ( including pinion) and solder it to the new one. Of course, you don't have to solder the pinion though.

The size is 2.5mm. I got Dubro Hex screws from my local hobby shop. Luckily, the guy that helped me happened to have the nuts in his personal stash and he sold me a couple of them.

Hi, the stock bolt size for the head is 2.5mm however, you can use 440 which I did, just have to force thread it in the hole a bit. Either way, get longer screws than stock and use a locknut and washer.

The best way to mount them in my experiences is on top of the head, I made a head stiffener about the same width as the head and mounted it on top of the blades for similar bracing as the stock location as I felt that just the washer up top would be too small of an area and will add more stress to the mounting area in case of a crash.

Drilling it out and mounting it in the stock location is the other option but I wouldn't recommend it, I broke a cf blade going that route, I'm using fiberglass blades right now which are not nearly as strong as the cf and hit a couple things hard and it hasn't broke with the way I have it mounted on top so on top is best bet in my opinion. Looks really nice with the home made head stiffener. I don't have a pic of it in my gallery so I can't post it but I can email you a pic if you wish. Or in fact, here's a link to a thread I posted the pic on, just scroll down a bit, I have a pic of it there. This thread is discussing this very subject on ezone.

Thanks for the tips. BTW, what did you use to make the head stiffener? Just got my hornet CF blades today & want to get this thing up in the air ASAP. I'll let you know how it goes.

Hi, I just used a piece of ply and painted it black. If you can get a piece of carbon fiber sheet, that would be really nice, I'm going to do that later...
