I rarely sell an airplane or heli. Most of the time I fly/repair/fly/repair until they are no longer usable!

Anyway, in this case, I decided to pass on my Blade mCPx. Here is why.
* The mCPx uses DSM2. - not horrid by itself for a little heli that flies within 20 feet most of the time anyway.
* I use a DSM module for my Aurora 9 to fly BNF planes with. It supports DSM2, 9 and DSMX.. but... not at the same time. I have to switch modes manually. It's painful because I always forget how and have to look in the manual.
* So... all my other UMX stuff is DSMX which makes it so I don't fly the mCPx too often.

Anyway, thought it deserved a home that would fly it some more. I put a couple last flights on it before sending it on its way.

The wings are fiberglassed and the 1st layer of primer is on and sanded. Next Iíll lay out a ton of chart tape to make panel lines on the wings and then Iíll give it a 2nd coat of primer and finish them. You can see the panel lines I made on the stabs. Theyíre finished primed/sanded and ready to paint. After painting, or in between, not sure yet, Iíll weather the panel lines. Should be quite the effect when done.

The wings are smooth as glass.. or well, fiberglass. Feels like a car finish.

Hardly ever do I get two great days in a row to fly. What a hoot. This was my 1000th flight. I wasn't being too aggressive since I rebuilt the Habu (see previous blog posts) and was sort of re-maidening. Worked out fine though.

This was a lot of fun but I need to see if there is a better mounting place and perhaps a better way than velcro to secure the camera. Otherwise I guess I'll have to stick to smooth electrics. Got some pretty good vibes on my 50cc

Recently did some work on the rudders. I like the hidden linkage.

So the throttle linkage broke on my 50cc engine today. This is the 2nd time this has happened. The first time my bro was flying the plane. He wasn't that high off the ground. As he came around to see if he could glide into a field to land it one wing was sheared in half by a fence that was difficult to see.

Anyway, since the same thing happened again, I've decided to get a threaded 4-40 rod and put heavy links on both ends rather than have one side with a solder clavis. I'm hoping that will create something that doesn't break after another 40 flights or so.

Anyway.. got lucky today.

Got replacement frame and put everything back together. Now to find a place and some weather to go fly it.

Oh yeah... great easy way to hang a habu from the ceiling. 1/4 inch iron rod from Home Depo or wherever costs $4 or so and some packing material/tape + one hook. I like it hanging there.

Well I did my due diligence and made sure everything we set up correctly. I had fellow rcgroups member swps there to help me set trims and stuff.

Worked out great.. until the end...

This plane is such a fun plane to fly. Had someone along to film for a while the other day.

Been doing helis and planes for a couple years. I came across a good deal on an unopened ARF F16 from Eflight. It's stock motor setup on the older kit is notoriously underpowered but I figured I'd give it a shot since it was pretty inexpensive.

Anyway, maiden flights went just fine. It takes a pretty good sized space to take off and land. It needed a lot of elevator to keep it in the air even flying around at full throttle. I ran it on some 30C 2200mAh batteries that I already had for another plane. I got about 4 minutes and probably could have gone another 30 seconds or so.

Overall a fun little jet though. Nice and quick for a park flyer.

I'm into numbers. I track each time I fly, each time I crash, how long I fly, which battery I use and other details. I can then find out the cost per flight, total flight hours, and lots of little fun tidbits about the hobby. I'm currently at about 560 flights and to date had a crash percentage of about 6.7%. That counts all the little dumb ones that I had when I first started learning how to fly RC airplanes.

Anyway, sometimes your number is up I guess. This week was not a good week for RC. To start off with, I had a moment of distraction when explaining to a co-worker how Flybarless helis worked. I was showing him the blades and such while putting in my 2nd battery pack and I somehow forgot to snap the canopy down tight. You can see yourself the effect of that.

So anyway, a couple hundred bucks of parts later it should be good to go again.

Yesterday I thought I'd get a couple flights on my Trex 450. The sun was behind clounds and it was in the evening. Some weird combination of light and a trick that didn't work out quite the way I wanted and all of a sudden I had lost orientation. I guessed wrong on the direction I needed to go and whammo.

Two helis in two days. I helped my friend bust one too. So really 3 helis in two days. Ouch. I think I'm going to go camping and riding motorcycles next weekend.

So the Axe 400 has been a good way for me to break into Helis and start learning about actually flying them instead of just playing on the sim.

I had my 3rd crash this last week. It was my fault. Two issues I should have known better and could have avoided. 1) After replacing the head with the EXI head, I had raised the swash to compensate for the shorter axle. New axles hadn't arrived in the mail yet. I noticed a few times testing it that I had to move the stick almost all the way forward or back for it to start moving. It didn't have enough travel. I't would start drifting backward and I had to give a lot of stick movement to get it to go back foward. 2) It was getting dark. I thought it was still light enough but I need more light than that to see and react clearly.

Anyway, Long story short it started drifting forward and I pulled back but it wasn't fast enough. Blades brushed a branch on a tree. I cut power and dropped it to the ground pretty quick.

Damages:
Blades, tail boom, tail housing, tail axle, main axle, feathering shaft, main gear, horizontal stabilizer retainer, flybar, tail servo mounts. From tower, about $50 worth of stuff. (Granted they do send you two of a number of those items).

Well, the moral of all this is two fold:
1) Replacement parts from tower hobbies are ridiculously more expensive than you can get for a number of other helis.
2) I'm going to start treating the heli like I treat my planes and only fly them if I know I'm not likely to crash

In the mean time, most of the Axe is still good. I'm ordering a body for an EXI 450 SE v2 and using the electronics from the Axe on the new body. It wasn't that much more (about $25-$30) than ordering the replacement parts from Tower Hobbies and if I happen to crash my heli again (cross my fingers), the replacement parts on the Exi are about 1/4-1/2 the cost.

So long Axe 400. This is the 1st time I've abandoned a plane/heli.
