 Thanks Iyer. Will try with another set of wheels.

I did not have a compass so used a round object to trace the circle. (In fact, it was a small speaker you find in the electronic cards). The circle for the outer rims were drawn freehand using the speaker outline as a reference. I found the centre by cutting a paper disc and folding it twice. The intersection point was the centre  8-). Then it was sandpaper and a bit of elbow grease.

Very nice sir. Especially the self made wheels.

Ashok sir,

What do you use for laminating the foam, any tips and tricks could be useful.
i use color paper(oil paper) for covering but it shrinks a lot and spoils the look.

I have not used paper for liminating in this model. The fuselage is built by laminating 7 pieces of bio-foam

However, I have built a few glow powered 46 size planes using 7mm bio-foam. In such models the foam used for building the models is laminated on the inside with brown paper while the outer side is covered with vinyl which is used for preparing signs and sticks on one side. I have flown these planes for a few years and are still in good shape. I am attaching a few photos of the planes built using this method. The models are P51, and two Cessana with 25 size engines.

I recall reading an article in aero modeller published long back where the author who was the pioneer in the use of foam for rc models covered his models with strips of newspaper, and after the glue had dried sanded the edges smooth. A coat of paint was all that was required thereafter. Try strips of brown paper/newspaper and a coat of paint. You will have a very sturdy model. After all paper is cellulose which is a derivative of wood. I have preserved that article but after my frequent shifting lot of my stuff is lost/left/untraceable. Maybe Iyer or other old timers might have the article in their collection and would like to share.

@Sundaram
Thanks for your compliments. In fact I owe my gratitude to my dear friend Mr Darius Engineer who introduced me to this method of construction.

@Iyer
You have seen the cramped confines of my workshop so models have to live in multi-storied cubicles like his owner. P51 occupies the upper floor while the raptor lives on the lower one.

The landing gear looks awesome, the shape in which you have bent the cycle spokes has left me wondering how you did it . :headscratch:

Here are the pictures. Total 3 spokes used for making the landing gear.

How did you cut those perfectly round disks?
Iyer sir: you can use hole saw for a perfect round cut. hole saw for drill machines are easily available in the local market it will cost you around Rs.250-500.

The original Fokker DR7 had an airfoil attached to the wheel axle. So I built one

Guys help needed. :help:. I just took out the LiPo I was planning to use. They have a JST connector. I urgently need a few JST connectors for attaching the ESC to the battery. RCDhamaka and rCBazaar are out of stock. Any one having spare JST female connectors. I need to do the maiden before 15th >:(

ashok baijal

The total weight is coming to 354 gms. I plan to use
Blue Wonder (Though the version I got from hobby king is crome coloured) 1700 kv motor
12A Hobbyking ESC
8x4 prop
Turnigy nanotech 850mah 2S 25c lipo
Cirrus 6ch mini receiver 72mhz

The wingspan is 33in, length 24in, area 300sq in.

ashok baijal

Just checked. A JST connector is rated at max 5 amp. So will be changing the battery connectors to Deans as the motor will draw around 10 amps

Thanks would need help as this will my first electric flight and a RC flight after a gap of over 5 years. Plan to fly this weekend but rains have started in Bangalore and expected for another 2 days. Praying for better conditions this weekend. Location not finalised yet. Could be in the cricket field in my son's apartment or Hoskote.

Yesterday was a bit unwell so just took the day off

Today morning we did the "Maiden" at my sons apartment playground. The video is available on Youtube at the following link
The ground is rectangular but the wind was along the smaller width. The landing was in crosswind. I had the "Eagle Squadron" escort.

@Anwar
Any size restrictions for uploading video on the forum?
