Its down to the individual. We have a club member who flies about 3 times a year, and then only on the club trainer. He has a loft full of extremely well built and interesting models. But most in the club have a mixed fleet of regular built and ARTF's. Cymaz, good point but it's the difference between driving and motoring I suppose. It takes all types ... Ian

I stand corrected - even if it doesn't work for me Ian.

So I've been having a crack at the Dawn Flyer. And so far there haven't been any issues that haven't been identified by others. The rear bulkhead issue was resolved by shortening the length of the first spreader on the rear 'crutch', I've made minor mods to the wingtips, not that they were needed, and I've decided to to modify the nose a little, just to be a bit different. The fus was constructed without the front 2 formers and once the tub was finished I stood the nose in some water and pulled the sides in to about 2/3 the width of the original. I've also left the sides at the front the full width of the balsa sheet. Once dry the rubber bands were taken off to leave the new shape. Apart from being a little narrower at the nose and a little deeper construction is as per design. Here's some pics of how far I've got. Glued the firewall in place this evening and all's looking good. ian

jrman, I love those old wives tales. If you don't believe me try this. In a dull light flash a small torch in one eye of a friend/partner/significant-other (with their permission and not too bright though) whilst watching the reaction of the pupil in the other. It should close rapidly. The part of the brain which controls this does the same to both eyes equally - unless there is some other issue. Bruce, I use Oakley glasses. Expensive but very good. Ian

Wha Flux do you use for steel
TheFlyingCrust replied to AJ's topic in Building from Traditional Kits and Plans
Try some of the flux sold by plumbers merchants. It works for me. A small tub isn't expensive and even though you're soldering steel, not copper, most are good for getting rid of that layer piano wire seems to get which stops solder sticking. There are several types, I'd suggest asking the man behind the counter. Ian -
Hints and Tips doesn't work on my MacBook. Otherwise it seems fine and user friendly. PM sent. Ian

Using SBC on Hitec receivers
TheFlyingCrust replied to TheFlyingCrust's topic in General Radio Discussion
Chris, I'd guessed this could be done with a separate telemetry unit. But with the Hitec, if all you want is LiPO volts monitoring there's nothing required, except the lead described. I'm tempted to go the full telemetry route as well, but in this case its simple. Ian -
Using SBC on Hitec receivers

Correction on OP. Its Optima receiver, not Spectra (thats the tx module!). All other info given is correct. Ian -
Using SBC on Hitec receivers
TheFlyingCrust replied to TheFlyingCrust's topic in General Radio Discussion
Tim. It all depends on the max input voltage of the receiver. Hitec Optima are 35v max. I suppose you could connect across, say, 5 cells and extrapolate. Using the balance socket allows that. Just make sure the 0v terminal is used. It wouldn't do to short the LiPO out with the neg on the BEC and the Receiver not being at the same voltage! Do you use another make of radio? What's their spec? Ian Edited By TheFlyingCrust on 04/03/2014 23:02:41 Edited By TheFlyingCrust on 04/03/2014 23:20:01 -
The guitar build is on hold due to a waterlogged shed (damp machine tools - dodgy) so I got on with the Dawn Flyer for the mass build. I'll be posting soon about that on another thread as it's getting near completion. But it's got me thinking about the power train. There's been much discussion re. not using too much of the capacity so I wondered if there was a way of "keeping and eye" on usage during flight. Reading the manual on Hitec Specra receivers they have a Supplementary Power Connection (SPC) which can be fed with up to 35v! (When in use the servo's are powered separately). So. 3S LiPO, Main leads powering ESC with its BEC powering the servo's. LiPO balance lead (just the 2 outer connectors used) with a lead with balance plug one end and servo plug other end. Remove jumper from receiver SBC and plug in lead. The onboard telemetry will now display the LiPO battery volts (with a bit of luck). Rather than jump in with both feet and fry a perfectly good receiver I checked with HitecRCD and they confirmed I'm ok. And it works! The Receiver Volts is displayed on-screen and I can set an alarm for low volts. Has anyone else tried this and been able to monitor LiPO voltage? Do other radio systems have a similar system? Your thoughts and observations? Ian

Just caught this right last week. Ian -

Do you mean one of these? From here? I have no connection with the company.

Thank heavens for a fine day, for a change! A quick visit to Durdle Door on the Dorset coast and got these 2 shots. Durdle Door Bat Hole -

I've just had a replacement boiler on a non-presurised system. They're regularly available and don't require removal of the loft tank for the primary side. Mine works fine and, as above, sooooo much cheaper to run. It turns out the old unit was down to about 55% where the new one is over 90% Go for Worcester Bosch. Very good very reliable and very popular. (no, I don't have shares in the company) Ian Edited By TheFlyingCrust on 12/01/2014 00:38:16

SAS Wildthing wind speed
TheFlyingCrust replied to I_AM_MARKEVANS's topic in Slope Soaring and Dynamic Soaring
Hi Stefano. First off, welcome to the forum and a happy New Year to you. I think Alan only takes telephone orders. That's how I had to get mine. He's very quick and very reliable. Just give him a call. Ian -
Doug Ireland, the aircraft used in "Phoenix" was a Tallmantz Phoenix P-1. It was made out of bits and pieces from a few aircraft variants. The pilot Paul Mantz, died in an accident , which destroyed the aircraft, during the making of the film. Looking at the photo on WiPed it shouldn't be too difficult to make a model of it. Ian

Hi TSK, Have a look here. I also have an Enya 19 VI. My father grafted an OS 20 silencer on it. It works as a silencer but he butchered the engine not the silencer. Oh well. The motor runs beautifully with a 9X4 prop. Ian
