|Thread: 4mm battery connector|
I have had the same problem.
I found heating plastic shroud with heat gun allows 4mm plug/socket to be pushed home. Don't over do it with heat gun!
|Thread: The Lockdown Restrictions Have Been Relaxed. Who's Been Flying?|
Not a very successful flying session then!
A lesson for us all that we need to be a little more cautious when returning to flying after an extensive layoff.
We have a similar problem (but a more serious one) at my gliding club (same for all UK gliding) where many pilots haven't flown since last September and when (if) we are allowed to fly again 2-seater flying will not be an option because of social distancing (2m rule), so no training and no check flights.

|Thread: Flair Hannibal|
Kevin - I assume your Hannibal is powered by a petrol engine?
Piers, I've sent email to you with CAD plan attached. A clubmate built a Hannibal from the plan last year.
|Thread: Glass fibre push rods advice|
Chris, when I have used carbon for pushrods it is tube not rod. I insert a threaded fitting (either threaded rod or threaded adaptor) to each end bonded with JB Weld (better than other epoxies for this purpose).
I think it was Macgregor's who used to sell carbon pushrod kits that included the end fittings and quick links.
I know people use carbon tube over a metal pushrod. For larger models use M3 threaded rod, but sleeve it with >3mm ID carbon tube. This provides additional stiffness.

|Thread: Flair Hannibal|
The contact at Inwoods is David Handley. I believe composite Hannibal cowls are available elsewhere including Carbon Copy.
BTW I have a CAD plan for the Hannibal if anyone wishes to build one.
|Thread: Sopwith Pup refurb|
Chris, Is the wing's leading edge carbon tube? I assume the Pup was built from a Balsa USA Pup kit?
|Thread: Puppeteer Wheels|
Have a look here and use the pull-down option menu Inwoods link
|Thread: Two Wings and a Round Engine|
I'm in a similar position also with a Flair Stearman in my kit collection. I have an OS Sirius fr5-300 radial that I plan to use. It will sound superb.
I am making good progress with a few projects so this may get to the front of the queue soon.
I look forward to following your build blog.
|Thread: Puppeteer Wheels|
I believe Inwood Models 3D print Flair Scout series wheels.
Otherwise check ebay. Original Flair wheels come up from time-to-time.
Currently: ebay link
|Thread: ED Super Fury Carburettor|
ED plastic parts were certainly around in 1973/4. A friend bought an ED Super Fury marine version and it had plastic carb and backplate fitted.
Malcolm and Piers thank you for your replies. Malcolm I have sent you a PM.
I don't know why ED decided to use plastic backplate and carburettor body.
I was given an ED 3.46 Hunter as a teenager by the local postman. The Hunter was in good condition, but lacked a carburettor. I bought one from ED that was plastic with plastic backplate. I succeeded in breaking at least two due to vibration. Fortunately, ED replaced both under guarantee.
I used the Hunter in my first single channel R/C model

With no model flying available today I decided to run up a couple of diesel engines.
I recently acquired an unrun ED Super Fury non-RC. On attempting to run it I noticed that the plastic carburettor body had a crack where it joins the back plate. It was leaking air so getting the engine to run properly was not possible.
i wondered whether anyone knew the best way of mending it? What type of plastic are ED carbs made from and what is the most suitable adhesive to repair it?
All advice appreciated.
BTW Happy Easter!
|Thread: Does the size of spinner effect prop performance ?|
Introducing some thread creep. What effect do large radial cowls have on the thrust generated?
I have a Flair Hannibal with no much of the prop disc area outside the cowl footprint, but it flies fine on a Laser 120 using a 16" dia prop.
|Thread: Pin Holes|
Yes the water trick works for removing dents as well. I've done this for as long as I can remember.I use a wet paper towel and squeeze water into the specific area.
|Thread: Mark's TN Hawk Build|
Personally, I have never heard of a Powerbox Sensor switch or Digi switch failing. I use both types of switch in most of my models these days as I've gone away from NimH.
Martin, I would be grateful if you could forward details of PB failures.
|Thread: I never thought it would come to this....|
Prune the trees either side of the gap and what's the problem even for a fast aerobatic model
Peter Russell (RCM & E Straight & Level columnist) used to fly his STOL out of his garden. Plan here: STOL Plan

|Thread: Multiplex Cockpit Sx 9|
Yes - you can setup curves on any control function.
|Thread: FrSky Major Update for most TX and RX|
Not Multiplex 2.4GHz M-link
|Thread: Do you remove your lipo from your transmitter every time?.|
Why do you use a lipo in a transmitter?
The current requirement of 2.4 Ghz is so low. Application better suited low to discharge Nimh, or Lithium ion.
My transmitters last days on a single charge.
