Slim Stick 2000 (Scratch Built) | Build>>Fly>>>

This is my fourth electric scratch build now. This is the Slim Stick 2000!!! Slim because it sports a symmetrical aerofoil 2mm depron wing and 'stick' for the slow stick boom used in the construction. 2000 is just for fun!Here are the Specs1) Fuselage - Slow Stick boom (6cm shorter than the original) and GWS plastic parts for the slow stick (servo mount/landing gear etc). Fuse lage length is 33.5"2) Wing - I used 2mm depron sheet and made a simple symmetrical aerofoil section wing. 6mm balsa used as the Spar. Ailerons are full length (almost). HXT 900 9gr Servo (1) for the alileron control. The wing is very light weight and stiff. - Wing Chord 8" - Wing Span 36.5" - Max thickness = 0.9" at 25% of chord. 2 X 10mm depron strips used to provide the thickness. - Ailerons are 1.5" wide and 16" long. They are made from 2 strips of 2mm depron with bamboo skewers glued in between them to provide rigidity. UH control horns are used3) Motor : Himodel 980Kv outrunner (10X4.7, 3S 1700mAh, 11.5Amp 107W in at WOT)4) Sx - HXT 900 9gr5) Battery - Himodel 1700mAh 3S6) ESC - TP MAG 18A7) Rx - R156FFlight review - All credits to Prady for test flying the Slim Stick 2000. The plane zommed ahead on take off and is a fast bird. The symmetrical aerofoil gives it the speed, though the glide is not all that great. I believe increasing the chord to 9" will give it a good slide characteristic. It flies really well and does some basic aerobatics. Inverted flight is reallly easy and stable. Rolls and loops are easy and the SS2000 handles it well. Overall a very good plane and virtually indestuctible due to the very nature of the construction. Enjoy some of the Slim Stick 2000 pics below.Rajeev

SLIM STICK 2000 - VERSION 2.1

The SlimStick2000 had met with moderate success. It completed around 10 flights before a nose first crash. The fiberglass stick had some minor damages, the stab broke in half.Well, I modified the design a bit. A new wing with 2 aleron Servos, Depron Fuse, faster motor. The result is SLIM STICK 2000 V2.1!!Today we maidened it at pancards and to flew great. A very easy build. Well I am very happy as this is completely designed by me. Prady gave it a thumbs up!Here are 2 pics.The specs are as follows1) Wing Span - 35"2) Fuse Length - 30"3) Chord - 8.5"4) Aileron Width - 2.5"5) Motor - Turnigy 2210/30 [ 1400kv, 8X6 GWS SF prop gives around 110W+ with 3S@ 12A]6] Servos - HXT900 7) GWS 6ch Naro Servo TP Mag 8 25A ESC9) Batt - 1800mAh 3S 20CAlileron, Rudder and Elevator Control. 2 Servos for Aileron Control.1.5mm Wire for as tail skid. SS Landing Gear mounted on 10cm long fiberglass boom. The fiberglass boom doubles up as motor mount holder too.Rajeev

SU-37 Quick Build - scratch built | Build>>Fly>>>

Another day, another plane!!

MIG-29 Quick Build - scratch built | Build>>Fly>>>

Hi,This is my second plane from Tomhe's (RC Groups) quick build series of pusher jets. Thanks to tomhe for the excellent design. The design and construction details can be found at rc.tomhe.net/mig-29Here are some details on the setup. 1) As with all of tomhe's designs, Mig-29 also features the tabbed consruction. The wing area is less than the SU-37 so I expect it to be nippier in the air.2) I am building 2 versions of each SU-37 and MIG-29. One will be a trainer version (low speed model) and another will be the faster version. The trainer version features a Turnigy 2215/20 motor turning a 7X6 GWS (500g thrust, 16A, 3S 2200mAh ABF). The faster version will feature a 2212-06 DY motor (5X4 or 6X4 prop, 23A, 700gms thrust, 3S 2200mAh ABF)The one that I am attaching the photos of has the following stuff on it. This will be the faster version of the MIG-29. Trainer version is waiting for a motor.1) Motor - 2212-06 DY2) Prop: 5X4 Gunther or 6X3 GWS3) Sx - HXt 900 9gr4) Rx - Corona 6Ch5) Battery - ABF 3S 2200mAh LiPo6) ESC - 25A MAG 8 TPI am currently flying the SU-37 Trainer version.Its really fun to fly these. I finally went solo on the SU-37 last week and really enjoyed the flight. Rajeev

DC power supply | SMPS for 12v upto 14 amps

This is about how you can use an SMPS (PC ATX power supply module) to get 12 V upto 14 amps output. I was in need of a relaiable power supply for my Hyperion EoS 5i DP charger and the smps I had (12V 2Amp) became useless when I wanted to use it to charge LiPo's of capacity >2000mAh. So I got myself a PC ATX SMPS and it works great and can supply upto 12V 14Amps.Got on to the internet, pulled out the pinout details for the ATX and the power supply was ready in minutes. Here are some details.ATX-1 Shows the pinout of the 20 pin connector. The commonly available PC ATX SMPS has a 4 pin connector attached to the 20 pin connector. This is removable. Read the pin out based on the main 20 pin connector.1) Short the pins 14(Green) and 13(Any ground: Black)2) Use Pin 10 (Yellow: +12V DC) and Pin 3(Ground: Black) for 12V DC power supply.

Home Made - Control Horns

Here is a simple way to make your own control-horns for foam aircrafts.

1) Basic Material - Plastic Credit Cards (which are defunct!!!)

2) Cut them to the shape shown in adjacent figure

3) Use a scissor to make holes for snap-on connectors

4) Bend the lower portion along the width by 2mm (use a nose plyer)

5) How to install - Make a sharp incision on the foam control surface. Apply epoxy on control horn surface which would make contact with the foam when it is inserted inside the incision.

Sat Oct 27, 2007 Flight Log - From around 10ft in the air there was a nose down crash. I dont know why. The Elepor is tough. But the crash resulted in a 1inch crack along the side of the nose and the nose itself was compressed along the bottom.

I have the following Modification to the nose since (see attached pic)
