Petrol power shouldn't require the paint to be fuel-proofed - cars manage quite well. Depends on the paint used of course.

At age 7 I got the chance to fly a neighbour’s model glider. Knowing nothing about such things I heaved it from his garden into the adjoining field, expecting it to come to earth within a few feet. Fortunately the field sloped gently away, and I managed a decent launch. Impossibly, it seemed to me, the glider flew at the same height for 200 yards before landing. I realised that flight depends on more than the strength of your arm. Thus was the seed sown. There followed umpteen 9-penny KeilKraft (?) chuck gliders, some carrying propulsion assistance or bangers around Guy Fawkes night. The great thing was that failures weren’t off-putting, they were interesting (!), and if you stuck with it things would work out. If we’d had superglue instead of balsa cement progress would have been faster.

To stabilise or not to stabilise - the gyro question
Brian Spearing replied to TonyS's topic in Gadgets and Electronics
I have an EagleTree add-on stabiliser in a small aerobatic model that can be hard to see clearly when backlit by the morning light. Usually flown stab-off but the spring-loaded panic switch on the Tx is a great comfort in turning an out-of-shape manoeuvre instantly into level flight. -
Having this morning shrink-filmed the wing of an e-Funfly, I’m considering doped tissue for the fuz and maybe the tail.

Propeller alternative chart
Brian Spearing replied to Christopher Morris 2's topic in Why Not Say Hello....
You can’t beat measuring what’s actually happening. Just get a clip-on ammeter and try different props. If you can multiply measured current by the battery voltage you don’t need a wattmeter. -
The Gov't, CAA, BMFA & UAV legislation thread
Brian Spearing replied to Nigel R's topic in All Things Model Flying
Dammit! I just had a quick look at the CAA test while waiting for lunch, and found myself with an operator number and a flyer number. Five minutes, maybe ten if you need to look at the crib. -
NEW POLL - do you use a throttle kill switch?
Brian Spearing replied to David Ashby - Moderator's topic in Model Flying Polls
I use a 3-position switch. Up - motor stopped, Mid - throttle range is from off to fast tickover, Down - full range. Obviously the mid position is for i/c only. The reduced throttle range is handy while carrying an I/c model to the takeoff point. -
I’d be interested too. Made one many years ago and would like to make another.

The online testing etc comes at a bad time of year for many clubs, being close to the annual renewal date. When we moved to a new patch a good proportion of members didn't renew - they were probably occasional flyers getting on in years but still valuable contributors to the club's finances. I can see something similar happening this winter, though I hope I'm wrong. Brian PS - Maybe July1st would be a better renewal date for club subs - but that's another matter.

Is epoxy the same as mustard?
Brian Spearing replied to Geoff S's topic in Building from Traditional Kits and Plans
Even worse is the stuff that goes off in the tube/pot. Cyano does eventually, as does some polyurethane glue. -
He wrote “First Light”, an excellent account of his flying life, full of detail and highly readable.

How to retain surface wires to foamy planes
Brian Spearing replied to Sam Longley's topic in All Things Model Flying
For holding the ESC, either tie it to the fus with zip-ties or if you prefer to stick it, use Uhu Por as a contact adhesive. The zip-ties can allow more cooling. -
Posted by kc on 25/05/2018 11:49:02: The engine stand in that video did not seem to fail - it was the cramp that appeared to slip off or vibrate loose. Obviously it is necessary to retain the engine stands with bolts etc. And it would also seem to be important to make sure the bench etc does not have a chance to move either. A big engine might move a 'Workmate' etc along the ground unless well weighted down. A 30cc petrol motor can easily tip an unballasted Workmate over, as I have discovered.

Macgregor 27 Mhz single channel (Time passes) Futaba FF6, pre-expo model. Various makes of Rx Mulitplex Evo 9 - an early one with rub-off lettering, but a grownup Tx. And several makes of Rx. Mpx 3030 - bought at a good price. Very solid. Used later with a Mpx rubber ducky aerial when I was using 35 and 2.4, to avoid forgetting to extend a 35 telescopic aerial (once bitten...) Mpx dragging their heels over 2.4, so bought a Frsky module for the Evo Spektrum DX6i - to get into 2.4 - kept for buddying. Hitec Aurora 9 - bought partly for its novelty, but a really good system. Sold when Hitec lost interest. Frsky Taranis, early one. Later a Plus, now my main Tx.

Hanger 9 P47 Thunderbolt 60
Brian Spearing replied to Rich too's topic in Build Blogs and Kit Reviews
My P47 is the bubble canopy H9 model. A Laser 80 powers it adequately and although more power might be nice I can’t be bothered to change it - it does sound good. Standard retracts have been OK with landing nose-overs usually preventable with more pilot care. Landings are surprisingly floaty.
