I just finished assembling an Art-Tech Pitts Special purchased from HobbyKing. My first order from the USA warehouse. Shipping was pretty reasonable, and fairly fast. Took about a week to arrive. Plane is pre-decorated EPS foam. It looks nice, but is probably going to be somewhat fragile.

The plane comes w/ servos, motor, esc all installed. Final assembly went pretty quick. No manual at all, and the downloadable Art-Tech PDF manual had no useful info at all! (No CG location, no suggested surface throws!) Luckily, there is a nice thread or two on RCGroups which has all the info if you search through it.

I'm going to use a 3S 1500mAH lipo pack to fly. With the stock prop (10x4.7" GWS style) it pulls about 10A. Might try a 10x8" GWS if this is not enough speed for me. Weighs 1lb 4oz. (20oz).

I just finished 'refurbishing' a Parkzone Typhoon 3D that a friend gave me in trade. It is an EPP park-flyer which people use to learn 3D aerobatics.

It has been through some rough use, but everything seems to work. I just cleaned it up, added my 2.4Ghz RX (trying an 'orange' 4 channel Spektrum clone) and a flight battery. I've got a 1800mAH 3S pack and with the 13.5x7 prop it pulls 15A, ~150 watts.

Will be nice to have something to bang around until the field drys out a bit.

I got a few more flights on the Hyperion Yak. Really like this plane.

I'm still getting used to it, so I've been very easy on it so far. I did let another serious 3D acrobatic pilot take it for a spin, and he did a lot of nice maneuvers with it. I asked if there was anything not setup correctly or in need of adjustment, and he said no ... just need to turn up the throws on high rates.

The battery is a 5S 4000 mAH pack and seems about right. Now I just need to get a couple more packs so I get more flights in.

Got a chance to fly my new 40e size Yak for the first time. Short flight, but fun.

Flying with the 'bundle' motor / 80A esc combo. 5S 4000 mAH pack. CC Bec.
Prop is 15" x 8.5" APC. 5 lbs 8 oz. total weight. 1100 watts in at full throttle.

Very high powered and fast combo. I just flew a few circuits and landed. Landing was pretty smooth. Nice performing plane. Hope to fly it again soon.

Short flight. She felt a bit tail heavy, so I'm going to tweak the CG a bit. Plenty of power. Nosed over the landing... need to practice my warbird flying a bit.

Reaper GR60 motor, MAS 13x8 3 blade prop. 85 AMP ESC. 4S 4500 mAh lipo pack.

Crashed it after a wind gust flipped it upside down and I lost orientation for too long. I think the fan, motor and ESC and servos are salvagable. The airframe is DOA.

Sometimes you just get something which seems to be 'cursed'. Either that or ducted fans are just not for me.

What do you think?

Are electric ducted fans just more trouble than they are worth?

I went to EAA Airventure in Oshkosh WI yesterday. Friday was the all women's airshow and warbird review. Got to see Patty Wagstaff fly her new Extra 300. Also saw the White Knight 2 take her 17th flight! Very cool.

Well the good news is the ESC is now programmed correctly. It performs well, but IMHO is still a bit 'under-powered'. The first flight went very nicely, but the second...

I purchased this completely built from an estate sale. Well apparently the builder (or perhaps the seller?) didn't actually glue the horizontal stabs into the fuse! On my second flight one came loose and was flopping around! Luckily I was able to land using 1/2 of my elevator on the other stab. Upon further inspection both stabs were just friction fitted into the fuse.

The hard landing squished the front of the duct slightly. Looks like an easy fix with very little cosmetic damage.

I picked up a Hobby-Lobby (J-Power) A-7 this past weekend at an estate sale. It was 'receiver-ready', assembled w/ servos, fan, motor, esc and 4S 2200 lipo pack. After setting everything up and static testing the motor, things seemed fine.

But at the field it was another story. For some reason the motor did not run up to the full RPM at full throttle. I fiddled around with the radio settings, blipped the throttle, but no luck. For whatever reason I tossed it into the air anyway. It was the most scary hand launch I've seen in a while. I floundered around holding almost full up elevator for a while trying to keep the thing in the air. Just about the time I was ready to give up and land it, the fan/motor suddenly sped up! I found was still at full throttle, and this provided full 'flying speed'. But I was still getting an odd pulsation in the fan RPM. (You can hear all this quite clearly due to the loud sound of the ducted fan system.) The plane flew well, but seemed a tad under-powered. Landings were easy, the wing loading doesn't seem excessive.

After landing, I found the battery to be quite hot. Apparently flying full throttle for 6 or so minutes sucked it dry. I did a 2nd flight with another pack with exactly the same results.

My guess is one of the following; fan motor needs 'cleaning' and/or bearing lubrication, ESC is faulty, ESC is mis-programmed.

I'll try to contact Hobby-Lobby and/or J-Power to get some ideas on how to remedy things.

Sunday was a great day to be flying. Low winds, and no one at the field except me for the first few hours. I flew all four of my air-ready planes multiple times. So far the Helios is my current favorite. Flys like it is on rails. Still getting used to the Extra 260, which is very responsive.

Flew the 'Jimmy Bipe' that I won at the Electric-Fun-Fly last weekend. It flew very well, but on my 2nd landing I nosed it over and did some minor damage to the firewall. Nothing a little epoxy won't fix.

I didn't really get a chance to 'wring it out' but it seemed to have lots of speed and good climb out.

Jimmy Bipe Specs:

40" WS
2lb 10oz AUW
3 HS-81 servos
AR6100 receiver
3S 2200 mAH lipo pack
Turnigy AerodriveXp SK Series 35-36 910Kv / 310w motor
Pheonix 35 ESC
12x10 prop

My friend Rick showed up at the field later and flew his Brio 10, Formosa and Cap 232. It was an all electric morning... Fun times!

I had a great time at this weekend's MARCS Electric Fun-Fly event. Highly recommended event. Lots of very cool planes, well organized and plenty of nice people. Check marcswi.org for details.

The highlights were a 15' wingspan scratch built Jenny and a Bob Violet Electrojet. The Electrojet was flown by a professional demo pilot and it was pretty amazing stuff.

I even won a 40" WS built-up bipe in the pilot raffle! It is a Dymond "Jimmy" which is rather amusing since I was a "Jimmy" when I was a kid. I'll get it setup to fly ASAP. I'll be sure to fly it at next year's event (provided I don't crash it before it rolls around).

I flew my Helios 63 today for the first time. I used the 15x8 prop.

The plane flew well with good authority. Very smooth and responsive. Plenty of power, it will go straight up as far as I'm willing to push it. I did some very basic manuevers on low rates and flew some circuits. The clouds were very low (about to rain) and the light was flat so I was having a bit of trouble with orientation. I held off on any serious stuff. Did several touch and goes and the plane lands very nicely.

The only trouble I had was getting decent 15" prop clearance on my grass field. I upped the wheels to 2 3/4" diameter which has helped quite a bit. I think I will adjust the tail gear to raise the nose a tad.

All in all, it is a very nice rig. I'm pretty happy with it so far.

Just finished setting up my latest plane, Hyperion Helios 63e. 55" WS pattern plane.

This one was purchased used for $380 shipped. The only downside was a section of the top left wing which has some trim that has been removed. It looks a little ugly - I think I will place some replacement trim covering over the spot.

It came built with:
4x HS-225MG servos
Hyperion Z4020B-14 Outrunner brushless motor
Hyperion Titan 80 amp PSB ESC

For power I'm using my Rhino 4S 3700 mAH packs.

The first prop I'm trying is a 15x8 APCe. Pulls ~45A, 700 watts static. I also have a 16x10 APCe which pulls 60A if the 15 is too tame.

AUW is 4lb 10oz - so I'll start out with 150 w/lb.

This is my friend's glow ME-109 maiden flight... I just edited the video.
VQ ME-109 Maiden Flight

Had a chance to get out and fly last Sunday AM. Good weather and fun times. The Aspera continues to be a very enjoyable flier. Just point and shoot. Very predictable.

The VQ AT-6 on the other hand... I caught a gust on landing and stalled / cart-wheeled it. It is repairable, but I'm starting to get the feeling this plane has bad juju.

So I've been working on building my Hyperion 40e Extra 260. So far so good. Nice ARF.

Finally got to fly the maiden flight on the Aspera. The short version is, this is a very nice plane! Smooth and precise in the air. Nice smooth take-offs and landings. No nose-overs here! (unlike my VQ AT-6)

My only complaint is that with the prop I'm using (13x8) and the 3S lipo and motor, it flies just a tad too slowly for my tastes. I'm going to try a 12x10 to see how that works.

(Update - Went up to 4S and now it really moves out. Plenty of speed and thrust on this setup.)
