Here are a few pic of my Tiger moths.

L to R - Phoenix TM(57"), Dynam TM (50") and Mercury (ca 1945) 33 inch.

Building Dynam Tiger Moth is a misnomer, it's akin to assembling a flat pack. Dynam even supplied a Philips screw driver so there not even need to buy one. A good pair of pliers is needed tho. The whole thing can me assembled in 2-4 hours.

The most tedious job is to fix the wing struts. I basically binned them and used my own method which allowed me to readjust the tensions, as and when needed.

I also had to rake forward the under carriage by an inch otherwise, like all other TM, she will nose over easily. A 4" vice is needed and the job can be done in 15 -20 min.

Engine cowling is like an egg shell - v fragile. Order a few extra which I've already done. Might line them with glass fibre and epoxy.

Here is the poem on Tiger (if anyone needs reminding):

My virtually od Storch (90 inch) still being built but weather is good for flying. So choose to change colour to HK Storch (42") to my favourite Swiss Air Force (1943) scheme.

A few pic attached to see the metamorphosis to a yellow colour.

Maiden yesterday - flew well (as expected) but needs CAR otherwise she has tendency to roll which can be off putting. Satisfied with her flying. Apart from colour, nothing else changed.

Here is my version.

You can tell - I enjoy flying and no time to tart up my Cat - she is an alley cat.

Cheers

Sad demise of Storch RIP :~(

17 November 2013

Unfortunately my Storch came to grief yesterday after she ploughed in to the ground from 15 feet. Pure pilot error - lost orientation - flying close to a brighter grey sky (where sun was) on a otherwise grey winter sky. The front end of the fuz and cabin virtually destroyed.

Prior to the incident she was flying really slow and low at not problem and club members were admiring her !!!

Well every cloud has a silver lining - I've already started building a ~90 inch wing for my Storch. I was also thinking that the current fuz might be slightly out of scale. So now I can build a proper scale fuz. but salvage some of the parts and use them in my Mark 2 Storch.

Cheers

Now that winter is almost upon us, building works starts...

I've reassessed my Vmar Storch and feel that I can improve both her scale design and slow flying character.

Vmar Storch is not really a scale model but a models which resembles Storch. I'm reluctant to use the word "Semi- scale" even. Her wings have wrong aspect ration.

Having researched real Storch from various drawings and photographs, I've started building wings for the Storch which would be more close to a scale Storch. It would then bring down the wing loading from ~23 oz/sq ft to less than 15.5 oz/sq ft. This should improve her slow flying performance close to the real thing.

Happy to write that building has started and I've so far...Continue Reading

I've have attached a file describing my solution to the above problem which has been mentioned in Guardian thread in April 2013.

Hope it's useful - I certainly regained my confidence in G again.

16 September 2013

The new version of the manual is now added.
Please note the main changes are in the Level and Trim setting sections and the rest is virtually unchanged.

Hope you find new version equally helpful

Cheers


There has been an error in cut and pasting of Trim and level setting. I'll correct it and resubmit the manual soon. I know about 130 members have viewed this manual since 1st September. Please bear with me and it will be here later on.

Thanx.

Here is my Final Version (1 September 2013) - written by a fixed wing flyer for fixed wing flyers.

E&O is expected but if you do find any then please bring it to my attention which will be gratefully acknowledged.

I'll update the doc from time to time, if necessary.

The Step-by-Step guide is correct in the respect that by following each step correctly, you'll be able to carry out successful flight tests. I strongly urge you to take your time over the manual and please don't be in a hurry or skip any step.

I've also given check boxes so that you can keep a tab of everything in every single step.

Cheers

Jamara "ISLANDER" a twin electric semi-scale model
I thought I start a build log on this model from Jamara. There was a build thread a while back but nothing updated.... so here I go....

Why I'm building it? This is a precursor to my Hanger 9 "Twin Otter". Since that's going to take a long time to finish so I thought I start another ARTF model which I can glue together and fly quickly.

The model details for those who're interest, suggest visit :

There is also a vid worth watching :

(music can be torturous )

My first impression is that it's a good kit [made in Taiwan(?) to German spec] and all bits fit together well.

Modification I've made so far :

1. Reinforced ribs 2 and 3 on both wings with 1/16 ply - this is needed to ensure it can take occasional heavy(ish) landings or taxing on rough ground.

2. Wing servo tray reinforced with a 1/4 x 1/4 spruce since there was springiness on the tray.

3. Wing rest on the fuz strengthen with 1/16 ply and 1/8 balsa.

4. Nose cone (inner) - added balsa to strengthen it, probably this was not necessary.

5. Elevator and rudder servo tray strengthen with 1/16 ply.

6. 1/16 ply added to half ribs where motor tray sits. That's done for both wings.

7. Wing joiners - not sure if I want to keep it as a 1-piece wing but may consider making it as a 2-piece wing for ease of carrying in small...Continue Reading
