Btw these are the wheels I bought ,not sure what the tyres are made of ,worried they might be a bit heavy for a TT.
Could I fix the wheels with a blob of Uhu or are there other methods?

 

[FDS]

They make most of the minis in larger sizes. You can just scale the plans up by an amount to enlarge them. If using 5mm UK foamboard you should lengthen the nose to counter the tail weight, as the dense board is not considered in the original design.
There are a number of scaled up plans available on the forum if you search, community builders like playing with different size builds!
With wings the simple under camber wing of say the SE5A you might want to look at a spar for the wing.
Get one bird in the air first, concentrate your time and energy into that, then start the second, third, fourth etc.

Hi again
FDS mentioned checking out the flexibility on my 1.1 mm wire I bought and it does seem more twangy than the official control rod.
FDS - you mentioned K+S being the right thickness for control rods,is this the one?
https://www.sussex-model-centre.co.uk/piano-wire-047-x-36-1-19-x-914mm
Also checked out your thread and somebody mentioned using pushbike spokes .Have got a knackered 26 inch wheel .
Haven’t got my callipers to hand but spokes look to me to be only slightly thicker but only about 2/3 as long as the official control rod.

 

[smiling albert]

Ps
If could get spokes same length (thinking road bike) as control rods one advantage is they have a thread on the end and wouldn’t the nipple thingy do for a linkage stopper?
By now you,ve probably realised I,m looking to save money where possible,it’s in my Yorkshire DNA I,m afraid!
That’s what attracted me to FT!

Bike spokes seem too thick to my mind.... Might be difficult to drill a hole to take them in the servo horn and still have enough "meat" around it to keep it strong.

 

[smiling albert]

Drat!
I knew there’d be a problem .Thought I’d found a goldmine!
Still can,t find my callipers but my mountain bike spokes look to be 27 cm long and road bike ones 29 cm.
That’s not long enough is it ?
Will keep an eye out for any penny farthings on my way to work!

I use 1.2mm piano wire usually, it's a pound a metre at the Leeds model shop. When I visit, I usually buy 2 or 3 lengths so I don't often run out.

 

[smiling albert]

Just tried poking a spoke in the horn hole,it is fractionally larger,still there must be a use for them somewhere.
How about undercarriage?

Worth a try!!!

 

[FDS]

Probably a good swap for 2mm undercarriage wire. I buy the 1.3mm Music Wire in 3 ft lengths, I am not linking the page again. That was what I sent you in the hardware kit.

 

[smiling albert]

Ok thanks everyone
Putting together a big order from HK using FDS s suggestions.
Apparently I need Velcro tape
Is this ok?

[FDS]

You can use any self adhesive Velcro you like, hardware shop stuff is fine, if the HK is cheaper buy that. You are only needing it to hold the battery in place, there’s nothing special about it.
A blob of hot glue holds the wheels on, I use a zip tie as well, my glue fell off on landing once.

 

[CarolineTyler]

You will need adhesive velcro - you would be better off with this...

 

[FDS]

Come to think of it the whole landing gear came out the fuselage slot the other week! I added a rubber band after that.

I'm sure many of you already know about this website but it looks good

Have just got some 1/16 inch plywood.
My calliper make it 1.5 mm thick.
The official FT firewall is measuring 1.8 mm and the horns 1.5 mm.
Hope my plywood isn't too thin to build firewalls?
Any thoughts anyone?
Also official FT control rods measure in at 1.35 mm
Also measured my bike spokes ,they seem to be 2mm so should be ok for undercarriage.
Don't throw your old wheels away without liberating the spokes first!

 

[FDS]

That will be fine. Make lots of firewalls. You might need some very small washers of your ply is too thin, to stop the motor screws hitting the windings. You can always buy the next size up of ply, thicker isn’t a problem.

 

[Headbang]

I prefer 2mm push rods, you can get 2-56 rods threaded on one end that fit nylon clevises.
1/16 ply might be too thin for a fire wall, I would double it up.

 

[Hai-Lee]

As for mini firewalls I use standard and cheap 3mm ply scraps from building sites and the like. The ply is thick enough to allow me to remove the "X" mount from motors and use the screws through the firewall directly into the motor. as a result it can actually be a little lighter and even stronger than the original setup.

It does take a little extra effort initially but saves a lot of effort later.

I often just shave the Ply firewall off of the crushed powerpod and fit, (glue), it straight onto the new FB powerpod piece. Often the same firewall outlasts the TT completely and is often reused on the new pilots next mini!

Just what works for me!

Have fun!

 

[smiling albert]

I know FDS and others will probably declare war on me for mentioning this but on old gu site he mentioned this controller as a rock bottom good buy.
any thoughts?
The reviews don’t see so bad that I’ve seen
