After my son build one with a KFM 2 wing section (see below) I was jalous and build my own with a KFM 4.
Great opportunity to compare flight character.
More neutral inverted with KFm4, astonishing flight for such a "stupid" wing section! I understand only from now the comments I red around those KFM wings! Congrats all the creators behind Funbat and KFM!

Turnigy D2822/14 1450 kv
8/4 prop
3 s 800

355 grs ready to fly = vertical take off

Balancing: 6 cm from the leading edge (2.4 inches)

Build from a kit found here http://www.napolskimniebie.pl/.
The seller "Marek" is very easy to deal with and sympathic.
Kit arrived in no time in 2 separate box. I asked for a sanded and shaped version.
The pieces were perfect for someone who knows what shaping EPP is.

Building is mainly assembling and reinforcing with carbon strips engraved in the EPP. Up to you to carve the nose for battery.
Result is above my expectations. I took example on Marek in refining decoration and I don't regret it! In flight the wow effect is fabulous. At least in my eyes...
3s 1300 lipo, orange receiver, 4 HK 9 grams servos.
First flights with 19 gr Turnigy 2204 14 T were underpowered. Replaced by two HK 2205A 1350 Kv and 8x4 GWS and it's a lot better.
560 gr rtf with battery.
Flights are very good and predictable, just some more top speed could be appreciated! But the more I fly this plane, the more I thing the available power is realistic ans as the true one you have to "pilot" the throttle.

Here my son build of a Funbat: well done, precise, straight! Pleased and proud to test fly it for him.

All out of 6 mm depron, 5 mm carbon tube spar
Weight 259 grs with a 3 s 800 lipo and a Turnigy 2205A 1350 KV, a 8x4 prop, 18 A Esc and 2 HXT 900 servos.
First flights revealed a very well maneered plane:
- Slow flight able due to the light weight
- Vertical take off able !
Not as fast as a racer but funny
I observe what i think is a "snaking tail attitude" at some speeds and I will try tails extensions.

I miss rudders but we will soon ad them.

Thanks to "Der Frickler", a very active German Modeller sharing a lot on his blog http://der-frickler.net/modellbau I build my first boat!
From now I live along a river and this boat is intended to recover my hydroparkflyers in case of problem ;-)

Design is "simple stupid" and re using a lot of laying around parts... speed 400, gunthers, not anymore at the top servo, a DX5 i use for training people to fly, a small lunch box :-)

Thank you to you "Der Frickler"

I came across this kit in my hobby shop. Annouced for 2.5gr servo's and a 2 S brushless motor, 50 gr rtf.
I decided to build it with all a 4-site equipment.
Flies well but it doesn't prop hang.
WS: 42.3 cm
Mean chord: 10.4 cm
Wing area: 4.4 dm²
Weight: 40 grs with a 160 mah Nanotech
Wing loading: 9.1gr/dm³

I converted a friend Twinstar 2 by using:
- BL Motors https://www.hobbyking.com/hobbyking/s...dproduct=14739
- Propelers tri blade 7x6 https://www.hobbyking.com/hobbyking/s...dproduct=16711
- Esc turnigy 18A https://www.hobbyking.com/hobbyking/s...idProduct=2168

Installing the motors was easy: removing the Speed 400 and attaching the BL from their backplate and 2.5mm SHORT bolts on the original firewalls.
Ready to fly weight is 1033 grams with paint and a 2200 3S.
Power consumption full throttle is 19A. With a Nanotech 3 S 2200 we fly 10'30'' with mix of aerobatics and circuits (not trying to save the energy)

I installed a buzzer in the nose pointing forward and with the quite silent sound of the twin BL, we hear it from around 100 m away.

I find the performances a perfect ratio of investment/power/flight time/performance. 3 blade propelers are not the most effectives but we fly in unprepared fields and it offers more ground clearance than 2 blades

I made some years ago a small proped micro jet with a fuselage made of a pipe insulation foam tube. Those kind of fuselages were created by Martin Muller for the Magnum Classic, Magnum Double...
I mixed this time this kind of fuselage with a bigger delta wing. See pictures as build log. Seems mee that construction images are self speaking and it flies superbly.

I name this jet kind "mytube"

2 s 800 lipo, 6 gr HXT servo's
GWS 7 x 4 drived by a Turnigy 3020 1800 kv
53 cm wingspan
54 cm length
180 gr flying weight with battery

I am teaching a friend to fly with a Twinstar. He is a very good trainee and a promising pilot. Sadly he lost one propeler and dived on top of a tree. As he is owner an running LOGEMAT a company selling and renting building equipment recovering the plane was a pleasure... for big kids with big toys! The plane has NO dammage! We will replace the pusched and glued original Gunther type propelers by something more reliable: aluminium prop adapters

Built one year ago, according to Chara plans and his excellent tread: https://www.rcgroups.com/forums/show...ighlight=bmr+2

One of my favourites one. Got around 50 flights so far and I'm always surprised by the difference between high speed and low speed passes in both cases without any bad habits.
- 3000 KV HK 24 grs mot, Graupner 4.7 x 4.7 prop.
- 2 pces 6 grs servo's
- Turnigy 12 A esc
- 2 S 800 mah lipo
- WS 68 cm
- Length 52 cm
- Wing area= 7 dm²
- 24 grs/ dm²
- 166 gr rtf
Built from 3 and 6 mm depron, hinges from painter tesa yellow masking tape: surprises often around me but it sticks very well on depron, remains steady and acrylic paint sticks perfectly on it!...Continue Reading

I will try to post one picture of each model I built and made fly... It will take some time, mainly for those before digital pictures. I am around 100 models between 12 and 5000 grams ...Continue Reading

Hi,
5 pictures, 360°, depron, epp, electric motors and energy... Not the biggest workshop but my favourite dreamshop where dreams come true.
I toke those pictures for myself hoping to see them back in 10 years and to compare

Here my participation in the tradition, thanks to Epp, optical fibers, leds and my son as cameraman...

Created by Martin Muller as "Magnum Reloaded". Shrunk and cnc cut in EPP by a friend, P51 motor, 1S: a pleasure.
Winglets, stab and fin 2mm depron.
Wing, horizontal surface and landing gear are remoavable without any tool. Weight 38.5 gr with one 138mah cel.
The canopy was made by shaping a form in balsa (it exists :-)) and heating on this a piece of translucent shrink tube. I needed some 1 gr weight in the nose: shame on me!

Here my version of The foamy: the DART XS. To enhance the scale appearance, I added a super realistic pilot of my own. As you see sculpting is one of my deep talents

From an undetailed small plan found here https://www.rcgroups.com/forums/member.php?u=234845 on I R Irv's blog. It's a Micro Mustang Dart, powered by a PZ 51 motor. It's not a floater but a very lively fun machine as all other darts. I added ailerons and it's 25 gr with a 160 Nanotech batt. 2 mm depron, nearly no carbon nor reinforcement. Sharpies decorated. Thanks Irv's for sharing this piece of pleasure.
WS: 23.6 cm
Mean chord: 9.2 cm
Wing area: 2.17 dm²
Wing loading: 11.5 grs/ dm²

Here my IMP (see scratchbuilt foamies, created by Aio_1): 6mm EPP, Turnigy 2204-14T 19g outrunner, 6 A esc, 2S 360 Rhino, 8/6 GWS cut prop, 2 pces of HK 9gr servos, total weight 145 gr. I prefered the 9 g servos because of the large moving surfaces
Power-weight ratio is perfect!
I begun with the first PDF plan and I reshaped according the author comments in post #15 .I built it before the author released the V2 plan.

I was born in 1967. Maried, 2 children, a dog... so classical
I Live in Namur, Belgium.
I begun RC in ...1982
I am an EPP, carbon, depron and electrons addict. I fly aswell in and outdoor. Electric only after years of nitro planes and helicopters.
Enclosed pictures of my son, some friends at some indoor venues, a guy I am teaching to fly and his father watching......Continue Reading
