some more 'auto epp foam slicer'.

Deepak

Looks like i need to get one from Mark

Gusty,
Mark calls his version "FISH" I think...
I have the profile type fuselage version as he does two ; one with profile and the other as his images above on page 2 will show...

I am going to do my maiden this Sunday if weather allows.. otherwise one of these days soon..will give you my views.

One thing for certain, I know I am going to enjoy this cheap and chearful toy. The more I talk about it to my friends, the more I am learning..apparently it is one of the most popular best value for money plane most have ever flown..Brian who taught me how to fly 15 or so years ago told Mark how he crashed his Mako on its maiden as he had too much throws on it and this plane can be a rocket....  

I like my planes to be good slow flyers and Mark has assured his EPP version will fly slow too if set up correctly as its has a larger wing area and the wing and fuselage section is much thicker.

Mike Pemberton has advised me on its control deflections based on the EPP version;
"  Hi again Deepak,  I have been flying the Mako, (plus other planes) this afternoon at the Frolesworth site, Thursday 13-Mar-2014. The weather was absolutely perfect - the best so far this year, although the field is still somewhat wet and soft underfoot!

You ask what deflections I am using on my Mako - the current 'set-up' is as follows -
1) Rudder movement - approx. 30deg left and right, i.e. +/- 50mm (measured at bottom of rudder).
2) Elevator (elevon) movement - approx. 10deg up and down, i.e. +/- 20mm (measured at rearmost position of elevon, adjacent to rudder)
3) Aileron (elevon) movement - approx. 10deg up and down, i.e. +/- 20mm (measured at rearmost position of elevon, adjacent to rudder).
Hence, total 'mixed' movement of elevator + aileron - approx. 20deg up and down, i.e. +/- 40mm.

Hope this helps with the basic 'set-up', but obviously it depends on your flying preferences as to what amount of movement you desire. If you are at all unsure I suggest that you start with less movement, then increase accordingly as you gain experience. You can do this easily by altering 'travel adjustment' on your transmitter!

Good luck, hope to see you soon! Best regards, Mike Pemberton.
(Happy Landings)  "

Mikes's 6mm DEPRON plane is 400 grams and mine in 10mm EPP covered in packaging tape at wings only starts at approx 478 with 1000mah Rhino Lipos 3 cell 20C, 485 with 1250Mah Lipos 3cell 20C, and 500grams with Zippy 3cell 2200 25c.

The C and G was not coming to 175mm as suggested by Mark.

Had to make these changes;

Install ESC right behind the firewall instead of its designated slot above the wing where Mark has left a slot with EPP Block left in case it needs plugging. This block will now have the rudder servo fixed in it.

Remove RUDDER SERVO and install it towards the front of plane at ESC'S slot.

Had to add a thick 10mm ply firewall to bring the motor forward so a 30 gram nose weight was added and motor moved at the same time... added a foamboard pcs too to bring it further forward.



I suggest  Mark to;
MOVE RUDDER SERVO SLOT FORWARD
MOVE THE BATTERY COMPARTMENT TOWARDS FRONT

BTW I forgot to show what I have done to all my LIPOS so they stay on models...VELCRO soft side, stuck and hot glued...  and models have the same done in the battery bays with spiky side of VELCRO...

I also tend to add a velcro strap to keep them in position so the C & G remains the same in case the velro fails to hold them steady in  their place... It is a good idea to securely fix this strap underneath a lolly stick or veneer ply cut to the length of the bay and stuck with hot glue..

Cool !! most of us do that i guess

Sorry Gusty...you are an expert...this comment was only for the novices...in continuation to the blog...
We all have a lot to learn from you so some suggestions and tricks picked up along all these years of your expert flying will be most appreciated....

Deepak

This must be new to gusty,

Stuck the spikey side of welcro to the back of TX. this holds the tx to the back of car boot(my brother's i20 has a soft spongey type floor in the boot) it sticks well and protect the TX from damage during transport.

Ashok.P

Good one Ashok. I have done the same to my T X case. Hot glued 4 pcs on 4 corners. As you mentioned the car boot mat acts as a soft sides and my case always stays at the same place. I learnt it the hard way when sudden braking and hard turning to avoid an on coming car sent my tx case flying to write my shock flyer off many years ago.

Very nice and innovative tip...

Allan's Model is coming up nicely..
All up with battery 1300mah 3 cells estimated at 390 grams without servos and ESC so approx 45 grams less than mine 490 - 40 = 450 max..

Weighs 40 grams less than mine as he decided to move servos towards front so no nose weight and less ply.

Mine is all ready to fly..some images;

More images...
I like what Allan has done to hold the battery inside the bay..I wish I had done that too as it is much neater and secure.... So you can use your imagination and suggest another idea.. The more the better..



Might be better to start a new thread!!   I think I might just do that..

Brian Kettle test flew - maiden his 'Mako' - however he's called his FISH. It went well and he's very pleased.

Fly's great and he's well pleased -
made from 10 mm epp foam weighs 500 grams -
used lolly sticks for horns and bbq skewers for elevon and rudder edges
built up body enclosing all the battery, RX and ESC 20 amp   
he put a 180 watt motor in on 1300 Mha battery
and 3 X Ripmax SD200 servo's

Elevator 20mm each way
Aileron 20mm each way
Rudder 35 mm each way
Balance 185mm back on the wing measured from behind the wood motor mount.

Very nice Mark. Looks good too. Brian is a happy man. When am I going to be A Happy Man with my B4GGU that you are building for me.

You make me laugh
- I was looking at the build list and requests on my wall and were at the front  - is going to be Skim or B4ggu -- ( I't happens that I have had B4ggu on the bench today) 
Shall I carry-on with B4ggu 

yeh 

just -finished the 7th Mako Fish

Nice one... yes please carry on with whatever..must have them this year..

I must say this Phish/ Mako is a superb flyer and has really been keeping me amused and surprised at its low level and slow flying stability... who ever is building one.... you will love its characteristics. It does all you would want an a good plane to do...

Hey Wibberly please can I have another one as a stand by... I wouldnt want to be without one while the sun is shining.. maybe I will cut myself from some 6mm Depron this time..


Hours of fun at such low price..
10 USD 180 watts to 200 watts Motor
12 -15 US Dollar 30 to 40 amp ESC
3 x 10g servos at $2,50 each....
6MM Depron, Biofoam or CORO material and some balsa with a spruce or bamboo wing spar to strengthen the wing.


Vivek made his from Foam board from Ashish in Delhi ;   Images attached...
4MM x 4ft x6ft aprox
Both side laminated bio foam sheet.
Price:RS 3. 72paise +tax per sheet.
Box of 20 sheets.

Ashish is based at ; Paharganj, Chuna Mandi, New Delhi.

He has used balsa as doublers for bottom of the fuselage and is yet to cut out holes in the wing, Rudder and Elevons to lose some weight. It will be then covered with Garware film and painted as all his planes.
It can be flown with a small diesel engine or electric.....

His has turned out at nearly 900 grams compared to 450 g in Depron or as mine in 10mm EPP that ended up weighing 580 grams after covering in packaging tape and some re-inforced glassfibre 2inch tape.

The beauty is it uses most 1300 to 2200 mah 3 cell Lipos from your hanger. Just slide them along the fuselage to get C&G correct...

I will post a video one of these days as now we have excellent flying weather in UK.. Last Sunday was superb 24 degrees C and this week has been 21 to 22 too..Winds are 8 to 13mph just the right conditions we long for.. Lets see how long it lasts..

Had some nice flying sessions with the Mako/ Phish as Flying Marcus calls it. Allan made a couple of videos, here is one, need to tell Allan;he must hold the phone vertical or we have a inclined angle video....  The other one is better..will post soon...  Its a pity, my Movie maker programme has stopped working and I cannot edit and make these videos better..  Anwar I need your help!!





Here is Allan posing with his Cap and me with my "Phish" or "Mako"

Here is Allan flying his Cap;

That is a well tuned aircraft. Smooth flying. Great to watch.

Cheers,
Asutosh

The Mako is a great model 

Sanj how about building one in CORO...and see how it flies..

I had an AIRCORE 40 aeroplane model (American) with a removable power pod for IC engine, throttle servo and rx 15 years ago. This allowed the modellor to have one pod for 4 of their planes from Air Core range.

It was advertised as an indestructible model as a man laying the wing down flat on the floor and jumping up and down on it...
For spar it had a hard wood baton 15mm or 20mm thick and approx 50mm wide and the length was a bit shorter than the wing length. It was placed at approx 50mm away from the leading edge and wing folded over and made up very similar to the your Cub...

The strengthener on the vertical fin/ rudder and horizontal stabiliser were hard wood dowels pushed into the flutes of Coro.

So one could use that strengthening technique and instead of a aluminium wing support? worth considering pushing a few carbon rods or bar B que sticks down 2 or 3 flutes if one can get long enough..  We have also seen guys using 4mm aluminium rods as dowels for rubberbanding wings to fuselages.. So a aluminium rod might be a good idea ..only need one of about 65cms long or even 50 might do.

Interesting project

Have to try it soon
