Sounds like a plan

Part of the fun of flying 3D is to experiment.a bit and find that perfect setup to suit your own style.

Correct. On my setup the 20x10 was lethargic. the 21x10 felt more snappy. I get a full 6 minutes of hard flying on a 6S 5000 battery with plenty of reserve left.

I checked it today, and I'm getting around 5700 RPMs.

Rainy days=no fly so i have decide to install a smoke system in my edge I have gathered most of the needed parts. Hoping to locate a muffler fitting and some tubing for making an injector. 2nd project for my edge is to re hinge the rudder, managed to loosen a couple of hinges with a ruder strike. Considering making the rudder removable by adding a music wire hinge. + side, with a removable rudder i will be able to load 3 planes 57 extra, 59 slick,74 edge and my entire family for outings to the rc club

I've seen the music wire hinges on the larger planes but I don't see why it wouldn't work on the 74 Edge. Are you planning on using the existing hinges after modifying them or are there some hinges you can buy specifically for this purpose? Good thing is that I haven't even started on my 74 Edge yet so I could do this modification from the start.

I am planning on using the extra hinges that came with the kit. I took a small file to the flange on the rivet an pushed the rivet out. I am going to attempt to cut the existing hinges apart, then drill them out with a 1/16th bit. or trying to melt them out. I am hoping to reuse the existing holes with some gorilla glue.

Just as a matter of mentioning, you can buy Robart hinge halves, so making a removable rudder is very easy....see this post.. and if I remember correctly, I used .047" music wire, and there is no slop....

1/8" halves...

3/16" halves...

One comment about drilling them out, is that you will usually end up with a piece inside the surface rattling around...no biggy, just annoying. As you said, you can use a soldering iron, but sometimes again, you end up with a piece ratting around. The last time that I had to replace a hinge, I cut off the big part of the hinge, then used a Dremel tool with a fine bit, and ground the very end of the hinge. I then used a piece of brass tubing the same diameter of the hinge, and filed some "teeth" on the end of a piece of it about 2.5" long. I put this in an electric drill and stuck it over the end of the hinge and just drill it right out..no problems at all, and nothing ended up inside of the surfaces..

Thanks Steve, I did manage to separate 4 hinges today. went pretty easy, just took a few light and i do mean light passes with a small file. and the lip on the rivet came right off. the rivet were very easy to press out. now i just need to find the right size wire for the hinges. as for the smoke system, I managed to aquire a 10oz. tank a pressure fitting some tubing and a TME simple smoke pump. Just playing around with placement right now.

Yes, those are the OEM hinges, they come apart very easily. The rivet that is used is aluminum.

The holes look bigger than the dubro's I have. Need something like a 104 hinge. I can't find much else.

6S or 8S?

I'm trying to decide if I want to go 6S or 8S. I currently do an even mix of 3D and precision. I will be buying batteries either way but I already have a CC ICE 100. What are the pros and cons between 6S and 8S? 6S draws more current since less of the power is coming from voltage, right? Isn't that why most 6S setup seem to involve 5000-5300mah batteries and 8S involves 4000-4400mah?

I compared the weights of the motor and batteries for 6S and 8S Hacker setups and got the weights below. So the 8S setup will be about 10 oz heavier. Does anyone know about how much thrust each of these setups make, assuming an 18" prop on 8S and 20" on 6S? The larger prop allowed on the 6S setup probably helps with 3D, right? I do like a very floaty 3D plane but I like to have enough thrust to comfortably hover at half throttle and have good vertical punch-out from 3D. Thanks.

Hacker A60-6XS (16.9 oz) + 5000mah 6S 30C (28.6 oz) = 45.5 oz total
Hacker A60-5S (21 oz) + 4400mah 8S 35C (34 oz) = 55 oz total
