Finally adding a Yak to the fleet.
ExtremeFlight Yak 54 EXP. 48"
Not the largest planes but can be set up without breaking the bank, and they sure are a lot of fun. A friend owns one and calls it a bit "squirrely" but that can be fun too.


I don't have a short temper. I just have a quick reaction to B.S.

They look a lot like a Sukhoi 29 I bought at Hobby King years ago.

As J Powers seems to be out of the model aviation business I just could not pass up a deal I saw on Banggood for the 620mm Rare Bear. This will be my third. On 4S, it's literally a pocket rocket. Lots of fun. And with the coupon code, was only $79.00 shipped. Why not?

Default RCM Advanced Trainer II

Just finished up this project. The "RCM Advanced Trainer II" is closely based on the plans available from Outerzone. Originally designed for a .46 glow engine, my version has been modified for electric power, via a Power Up 46 brushless connected to a 5s, 4200mah 50C lipo through a 80 amp ESC. Swings a 12 X 6e prop. I also modified the wing mounting by incorporating the upper cabin section of the fuselage as part of the wing. A small change in the wingtips stretches the span to 57.5" Although not on the original, flaps have been added. A Mobius video camera is slung on a standoff mount on the lower fuselage, between the LG struts.
Maiden flight will have to wait until a new velcro battery strap arrives. The one I thought I could use won't fit around the battery.

What goes up, must come down. The trick is to keep it in one piece.

Default Extreme Flight 48" Laser EXP

Salvaged the components from an EF Edge 540. Was an amazing plane but wanted some variety.

Motrolfly 2820-950kv Replacing all 5 (yes five!) bearings $4.95. VERY nice motors. 4cell LiPo swinging a Xoar 13x4PJN. The prop rips with this setup and has an insane amount of pullout authority.

Edit: Final balancing would have required 2oz of lead or a heavier motor with the ZTW 85amp and Castle BEC. Decided to install a Castle Talon 90 instead...

4x KST DS215MG V3 servos at max voltage.

Lemon 7ch 3axis stabilizer receiver & satellite.

Dubro Nylon hinges and 2.5" Sport wheels for grass field.

Plenty of carbon fiber longerons and large G10 landing gear plate.

45.4 ounces without battery.

Maiden when weather permits...

Just getting everything back in order after a bad 2.5 yrs of not being able to fly. This isn't new but I did redo everything because in the moves most of my planes got damaged. My grandfather before he passed was making super flys out of floor foam and was having a ball so I decided that's a good place to start again while I get the rest of the fleet flight ready. Looking to get this airborne ASAP!
Cc 40amp esc
Super Tigre .10 motor
Spectrum micro digital servo
Ar6000 receiver
10x6 master airscrew prop
30 amp @ WOT w/ 300 watts of go go juice.
Overall weight 14.7 with a 3c 2100 lipo

I picked up a never flown Starmax 70mm F5E from a buddy for cheap. Its EPS foam, so light but brittle. Comes with servo assisted retracts, Kind of funky and they were an engineering marvel at the time. A servo pushes and pulls a rod tied in with the plastic linkage. The steering servo is actually mounted on the nose wheel strut. These will most probably be one and done on our grass field. This plane was introduced 9 years ago.

Swapped out the power system with a Dr. Mad Thrust 1900kv 11 blade and a CC 80 amp esc. Small battery compartment that I modded so I could fit a 6S 2700mah 35 RT. Ran it up on a wattmeter and she produced an initial 1300 watts then dropped down to ~1,135 watts steady. Should be plenty of power. This 1900 kv motor wants power.

She's ready to fly but I have grave concerns about the Castle Creations 80 amp esc. It gets very hot and it's exposed to the air on the undercarriage. I mean it gets hot just running her up on the bench. I'll re bind setting up fail safe where she gently falls out of the sky- LOL Slight up elevator

Hi Hawk, just curious, what C rating is the 6cell battery. pulling 1100 watts out of a 2700mah pack won't make for a long flight. what was the amp draw on the bench test? will 80amp be enough? castle esc's are meant to be used in confined spaces where other esc's would fail for sure.

My wife to this day makes fun of a styrofoam su-27 that was a brushed model I just had to have before ever building a balsa model. it is also 10 years old and cost $178 back in the day. After it arrived I read reviews that were very bad I always thought I would toss it up in the air some day but wound up building balsa and flew those instead. It still sits in thedeap[buried] corner with twin brushed motors and if it ever crashes , it will be styrofoam everywhere. Someday I'll take it out and replace the 2 brushed motors with something more reliable. till then....she sits as a reminder not to by impulse ever again without reading all the fine print online first.

narrow is the place to land...wide is the space to crash....choose the narrow way!

Stu,
Wasn't watching for the Amps but will retest tomorrow. That 1900 kv motor could easily go 8S. Better suited.

Tested the same RT 2700mah 35C batt in my F-35 with the 2750kv FMS 12 blade and got over 2000 watts but the Amps were near 100. I only have a 70 amp esc in that one. A no go. Or I can look for the trail of white smoke.

Have a 2100 kv XRP 14 blader in my FW Yak-130. It also produces over 2k watts but Amps are high. Around 100. I do have a 120 amp esc in that one. I set the timer for 3 min. She's one of my fastest.

Hawk

I picked up an E-Flite Timber while at SEFF. Wanted a nice backyard flyer and the fact that it came with floats too was a bonus with all the lakes around here.

Went together nice and easy and had it out to the field Sunday afternoon for a few shakedown flights. It flies really nice and is quite responsive with the stability controls turned off.

Haven't had a chance to get the floats on it yet but am looking forward to that sometime this summer.

I know most have seen this and maybe read my build thread ... but she really is a beaut !



And she flies superb ...



If it doesn't play ... then here's the full Youtube link : https://www.youtube.com/watch?v=9tL_V99a1Vw&t=673s

For about 80 Euros the kit + shipping .... a 4250 500 Turnigy motor .... 13x6 wood prop with a 5S 3000 normal pack .... amazing value i reckon.

All I need now is my SoloShot3 camera system and I can really do her justice !! (I'm told I could have it late May early June ... but they don't say which YEAR !!)

Maiden of my Blade Torrent. 2s vs 3s. Pretty fun little machine. Will be good for vacant playgrounds at schools this summer. Partner to my Aurora 90.
