I present you Sultimate V2, my 2008/2009 indoor season Aeromusical plane. Last year plane was very successful design and bring me many victories in international competitions! Questions; what can be updated on already good plane? Answers; 1.Increase control surface area is not a bad idea;)
2.Making plane slightly bigger for better appearance in air.
3.Searching for better equipment. And here we have Sultimate V2; New scheme.
Technical info; Fuselage lenght: 90cm
Wings lenght: 83cm
RTF weight: 140-160g, (depending on equipment), plane in picture weight is 149g rtf.
Radio: Jr 9V2 Gold, RX: AR6300 (~2g). Servos: Hitec 65hb on elevator, D47 rudder D47S on ailerons both Dymonds connected to 2s lypo. Best place to buy these servos at Aerobertics.be Propeler: GWS 8X4.3. Bottom of plane, you can see two D47S servos on ailerons. 
Bigger plane need more powerfull engine, Axi2203/Race handle job really well.
In last 4 years i flew with Vytas CD-R motors, unfortunately we lost stator suplier, and further motor production is under big question. Other stators we test don't give even close results that we expect. So i had to find more powerfull silent motor ASAP, since first serious F3P competitions waiting for me already in next month. Some of my RC friends, like Benoit Dierickx, Gernot Bruckmann, fly with Axi motors with great success, so i decide to try it as well. New Axi 2203/Race was beyond my expectations, very well build, motor have really good trust and at same time don't make to much noise, that is very important for Aeromusical. In video bellow you can see what i have in mind, actually i set only 85 percents thr curve on my TX, since i don't need so much power for my Aeromusical routines!
  | Motor Specification | | No. of cells | 2 Li-Poly | | RPM/V | 2300 RMP/V | | Max. efficiency | 74% | | Max. efficiency current | 3 - 7,5 A (>69%) | | No load current / 8 V | 0,55 A | | Current capacity | 9 A/20 s | | Internal Resistance | 220 mohm | | Dimensions (diameter. x lenght) | 27,7x21 mm | | Shaft diameter | carbon 3 mm | | Weight with cables | 18,5 g |
So im happy to announce that affter possitive testing Model motors aka AXI , become my sponsors, im really happy to start work with them. In any case i will use Axi motor for Aeromusical planes, and for pattern planes i still be ussing good light and reliable Vytas bruschless.
Best and most powerfull indoor lypo packs from Flight power. Better than 1000 words is one video, so enjoy;
This time we test something different , video was captured with fish eye lense, special thanks for Aleksei from MyResearch.

Summer and good wethers are almost here so its time for outdoor flying, my first outdoor project for 2008 season is Extreme Flight 58 inch Extra 300.
Few words about my electric Extra setup;
Battery; Flight power EVO25 3700mah 5S packs, each of them is about 480-490g with connectors.
Motor; Torque Revolution.
Prop; APC-E 15x8.
Servos, Hitec 225mg on wings, Airtronic 94751 and HS 5245mg on elevator.
RTF weight is 2564g.
Such setup have crazy power! I never had plane outdoor plane with such performance! Flight Power lypos are amazing, i set my thr curve on radio to 90 percents, and still i don't need to move stick all way up! Affter 5 cycles of brake in lypo batteries i set timer to 7;30min flying time. After 7;30 quite hard 3D flight i have to charge packS about 3000mah, and packs affter flight are just little warm.
Good idea is to put white tape on side of battery to start marking (with marker short line on side of pack) each charging, so i will be able to know and share with you real numbers of cycles/flights i can make with top brand product. My first EF Extra video. Quite windy day, but plane handle wind well.
Music in video is Drop kick Murphys - Rocky Road To Dublin and Dire Straits - Brothers In Arms.
Most interesting/usseful threads about EF Extra on big forums; RCgroups , RCUniverse, Flying Giants . My own thread on Flying Giants . Great building review on RCgroup.
Also don't forget to visit thread on RCUniverse about big 50CC Extra. |

This year i end F3A season earlier and right away start designing and flying new indoor planes. Almost all my AM and F3P designed planes was biplanes and i was little tired of such construction. So this year i decide to try something new, at this point i look at real aviation and pick successful aerobatic plane SU29. Like most Russian aerobatic planes it have huge fuselage area. It is good for indoor aeromusical plane, since usually AM routine include allot of flying on knife edge, rolling circles, integrated loops, ETC, (and big fuselage area help here).
Main idea was to create mid size light overpowered indoor aerobatic plane with huge control surfaces and big deflections for crazy 3D aerobatics but still with capability to perform slow precise maneuvers . Here in first picture you see second prototype, with few small changes, in my opinion now it fly perfect. |

My friend bought Extreme Flight 47 inch Yak-54 , he ask me to build this nice ARF for him. I was curious to look how quick i can build it, since Extreme Flight planes are top notch when it come to kit quality and flying characteristics i suspect it will be super fast. Here is first view right after i open box:
Technical spec's:
Wingspan, 47.5 inch ( 119cm)
Fuselage lenght 43.25 inch (108.1cm)
Wing area 425 sq/in
Weight with battery 38-40 oz (1064-1120g) according by EFrc. Equipment i will use: Motor: Torque 2814/820
ESC: Airboss Elite 45
Battery: Flight power EVO20 3S 2500mah
Servos: HS65hb all around.
Prop: APC 14x7E Weight: Same as Vanquish Yak is also buildet wisely, i can see it is super light weight airframe because of many lightening holes in its wooden construction. Material for most of plane construction is hi quality balsa and 2mm plywood. Hatch is attached with 4 magnets, it hold very good, and when you open it you get very good access to all equipment inside fuselage. First thing i want to know is weight of each detail, so here it is: Left wing: 67.4g
Right Wing: 68.5g
Cockpit: 79.0g
L.Aileron: 19.7g
R.Aileron: 19.3g
Stabilizer and elevator: 28.0g
Rudder: 17.3g
Fuselage: 223.5g
Carbon wing tube: 17.g
Cowling: 63.1g
Landing gear: 33.5g
Wheel pants: 8.2g ---------------------- Total parts weight: 644,5g (~23oz) + hardware 47.2g (1.6oz). (To be continue..)

I mentioned that i will show "Know how" tricks in near future, so here it is very useful tool for foam planes builders Beveling tool. With it you can easily make even good looking 45 degree angle cut outs on ailerons, elevator, rudder and torque box lines. It is very easy to build and use. Here is items you will need to build this tool: - 3 ore 6mm balsa sheet ( depending on what thickness depron you will use).
- Sharp shawing blade, as you see yu will have two parts from one blade.
- Balsa stick ~10x10mm
- Jigsaw for 45degree balsa stick cutting.
- Template for 45 degree cutting ( it also can be 60 degree, its dfeppend of what your needs is).
- CA gluess.
