Got a chance to meet up with Jon up in SR to get some shots of the RCLander Rafale and a few other planes in the review queue. I've been flying the HobbyLobby A7 for a few weeks now, and Im really enjoying it. My favorite part of the plane is how good it looks in the air, but I really don't have anything bad to say about the plane. It's really well behaved all around the envelope, and incredibly easy to hand launch.

This will be my first big event, and Im really looking forward to it. With the build/acquire phase of the prep work complete I can finally focus on getting some stick time. Looking forward to meeting a bunch of you fellas out there!

My latest project from Nitroplanes.com, the Art-Tech Eurofighter 2000 RTF.

64mm EDF made to run on a 1600mah 3s lipo, with a 30A ESC ... all provided with the kit. I'm thinking it should move along pretty well.

Watch for my review coming soon.

So thanks to Richard Carlton, I couldn't pass this one up

I'll be piecing it together over the next couple months ..... e-power of course.

More pics to come when the rain goes away.....

Had another good day today, it was filled with highs and lows. Here's some of the better pics I got, lighting was less than optimal with light rain by late morning.

I got out to the field again with my daughter and my good friend. A few guys managed to shop up that are regulars out there, and a good time was had by all.

My friend Mike and I attended the Fun Fly hosted by Delta Valley Flyers @ the Stockton Fairgrounds.

We had an awesome day, enjoyed some great indoor flying, conversation, and BBQ .. best of all left with some cool stuff from the swap meet!...Continue Reading

My first electric conversion is completed. I successfully maidened it on Thursday 16 October, 2008. I chose this kit after seeing photos of it here on rcgroups.

The first thing I noticed about the kit was the quality of the fiberglass work for the $120 I paid for it from akmodels. Alex provided great customer support, and answered all the pre-sale questions I had in a timely fashion. This being my first kit of this size, Ill say the included hardware kits are of decent quality. I ended up using most of them, with the exception of a few screws nd fasteners.

The plane is powered by a turnigy 50-55B motor, spinning a Master Airscrew (MAS) 11x7 prop. 80A Turingy Plush ESC, 6s 4400mah packs (4x 3s 2200) positioned 2 in cowl area, 2 behind firewall. Fixed gear, as I hate fiddling with mechanical retracts (all retracts for that matter).

Maiden flight was a success, with the exception of the landing whcih resulted in bent gear. Result of pilot error (way too much speed on approach).

I finally decided I'd build a plane AND cover it. After doing some research, and weighing the balance between construction technique, cost, and size, I decided on the manzano laser (www.manzanolaser.com) Avro Arrow.

Construction for the most part was pretty straight forward. All the parts came laser cut, in a priority mail package. I spent about 5-7 nights after work for the construction phase, and another 2-3 for the covering. I just finished up installing the ESC, rx, and servos. All that is left is to decide on a motor, balance it and go fly. Ill report on the flight characteristics once the maiden is over.

As for the finish, I have enough time invested in it as is. I want to fly it before I spend any more on decals etc, but I do have plans for some canadian markings if all goes well.

Just built this beauty. Went together in about 5 hours, and with minimal structural re-inforcement. The hardware kit that came with the plane was incredibly complete. I truly had fun building this plane, and it looks good to boot!

Factory w/ Factory supplied decals!

Batteries:
3s 1350mah 10 - 15C

Build Log:
Build took 3 evenings, about 4 or 5 hours for me w/ decal application. Nothing too crazy, just read the instructions over a few times for each step before you take any action. Motor/Prop combo is pulling 83W after 20second run @ 7.2A. Burst on fresh pack was at 89W @ 8.1A
Day 1:
* Glue the motor mount insert into place
* Install motor mount after epoxy dried
* Adjust shaft length as needed per prop spacing from cowl .... a little too much but its the best I can do w/ this setup. I suspect the mpjet motor is a tad smaller
* Using small amount of glue, attach ESC to rear side of motor mount and glue wires to mount
* Attach prop and test rotation direction
* Install cowl and reinstall prop
Day 2:
* Paint prop (chalkboard spray paint w/ testors yellow)
* Install Elevator servo
* Install aileron servo
* Glue down elevator pushrod tubing
* Mount rx
* Verify throws, and travel direction
* Program tx
Day 3:
* Install battery tray
* Glue canopy into position
* Start application of decals
Flight #1 (maiden) Report:
Temp: 75F
Winds: Steady at 10 - 12kts
Notes:
Decided to have Paul toss her for me, @ about 1/2 throttle. Flew right out of his hands .... wonderful flyer. I did notice I needed a bit more throw on the elevator as I was having to use lots of up. Unfortunately I was involved in a midair collision which resulted in the total of my wildcat, and significant damage to an Eindecker. Sad Day, but all the other planes flew great .... it happens

Sidebar:
With the 8x6 prop Im showing 194w and 21.xxA after a 15 second burst. Initial readings were 212w @ 23.xxA on the freshly charged 1600mah pack. My Cg with the pack all the way forward is about 3mm off of the recommended 6 forward of the spar in the wing. Im just barely forward of the spar.

Flight #1 (maiden) Report:
Wind: < 5kts
Weather: Clear skies, 80F
Battery: 1600mah 3s 15C Loong Max
Flight Time: 3:30
Notes:
After adding some more details last night I balanced her and no matter what I did with the battery I couldnt get it too balance, too tail heavy. So, I had to add the dreaded weight to the nose, ended up adding a total of 1.5oz.

After arriving at the field this morning, and flying the f-16, I figured we might as well maiden this thing. I had Mike give her a toss for me at about 1/2 throttle, and away she went. No trim really needed (a little left aileron ... 2 or 3 clicks). I climbed her up to check stall char., and noted how briskly I was moving @ 1/2 throttle. As I chopped the throttle, I expected the nose to drop with all the weight Id added, but to my suprise she stayed pretty level and glides well. Next up rolls,...Continue Reading

So I finally picked up my 2nd j10 NPS kit from aeromicro yesterday, so I could finish her all up. I made a mistake assembling the canards on the first kit and mangled some of the pieces All my fault, just in too much of a hurry.

Im using a HET 6904 fan w/ a generic United Hobbies brushless motor. Im planning on running 4s 2250 if I can get her to balance (well find out after dinner here). It pulled 501 watts on a fresh pack after 10 seconds. 3s seems pretty solid as well, Ill run numbers on it as well.

While taxiing the plane up and down the street with a 3s pack, gusts of wind tended to knock the plane over, and caused some slight foam damage. I repaired it, but the wingtips are a bit fragile.

All in all, it was a fun build (a bit time consuming compared to other GWS kits Ive done), but the kit came w/ extensions and all other required hardware (minus servos, ESC, etc of course). Hopefully Ill get to maiden her tomorrow morning, and someone will be around to snap some good pics

Ive had my eye on the phase 3 for a while now, but it turned out I got the new electrifly l39 before the phase 3

The L39 flies well on the stock setup, handles the wind pretty well, and rolls very nicely. Loops from a shallow dive. My favorite part about this plane is its basicly done out of the box. I think I spent about 3 hours building it total, and I spent about 45 mins just grindind down the screws I needed to mount the motor (which werent supplied with the kit btw ).

The phase 3 Ive yet to fly, as i just got it done last night. I painted, built, installed and dialed in all the electronics in one night. Started at 4pm and was done by 12:30am. The paint took the longest, followed secondly by the amount of time it took to scrounge thru decals and find a couple good ones for this fella. The tiger decal was purchased from here on rcgroups.

I cant wait until sunday morning, Im gonna have a grip of planes to take out to the field

The GWS kit is really nice, and I love how the A4 looks, but it leaves a little to be desired performance wise. So I decided this one would get the 5 blade rotor in the stock alfa fan w/ a little screamer motor.

I took some creative liberty with the decals (ala marines and navy stickers), otherwise its jst like everyother a4 Ive seen

Maiden report soon.
