Thread: Balancing jig

Why though when Vanessa costs nothing, is easier and more accurate? smiley

Thread: Where do you get your Lead from ?
14/01/2021 18:49:09

For trimming I use car wheel balance weights, they're not lead but are quite heavy and self-adhesive, they come on a strip marked with individual weights.

Thread: Watts/lb misleading?

I use 100w per cc of glow.

Apparently if they go faulty they will default to on.

This is a misunderstood generalisation - a powerFET as a device in isolation will usually fail short (ie 'on' ) but the switch unit as a whole could have other failure modes, the gate control circuitry could fail or become erratic with water ingress, the power button could fail (is it a dimple contact or capacitive proximity?), and of course wiring, plugs & sockets could fail or oxidise - my point is that 'default to on' applies only to the FET itself - other fault modes could switch the FET off or otherwise break the circuit.

They're probably very good, and better than traditional switches, but they're being touted as 'failure proof' which they're certainly not smiley

Cheers
Phil

I know that criticism of moderator decisions is against the rules, ...

I think this is a bad rule. There should always be the option for an alleged offender to clarify his post or to explain an allegedly non-compliant opinion wink

Thread: Veron Impala gets a dusting off
02/01/2021 14:30:51

Yours is definitely a 'Big Impala' Cliff - it was an entirely different design to the 'Impala', longer & more slender, with a larger span with innovative plastic moulded wing ribs.  

Standard Impala fus length is about 35" and 52" span.

My fave Impala is my 75% version (on the right with the Orbit reeds) teeth 2

I'd fix the old one wink

Thread: Help with PCB
29/12/2020 19:35:52

This reluctance to tell us anything about the project is intriguing Bill - maybe the RCG crystal ball will be more revealing... wink 2

Same question on RCG

28/12/2020 18:33:49

Bill there are probably many who are willing to help but without knowing what the project is, who designed it, or anything about it you make it difficult. Take it from me the guy will not be offended by a construction query.

Thread: Plan recommendation for first Slope Soarer
24/12/2020 10:00:09

Another vote for an aileron Soarcerer John, built lightly it will fly on a breath yet is fully aerobatic and is great fun to fly. Most dont bother with the rudder, you can have a blast with 2 channels whilst saving a bit of weight.
Daves one-sided fus construction method didnt work well for me, mine were all built conventionally - side, formers, side, pull it in, sheet... but others have said its a good method, each to his own.
Good choice.

Thread: Electric control line with R/C ESC
22/12/2020 10:19:20

but you dont get that 'connected' feeling that you get with trad C/L... smiley

21/12/2020 16:28:59

I prefer the controls on the handle, that way I've a free hand to save myself when I fall over... wink

Is it me or was throttle backwards ? I know an old boy taught on reeds flys that way. Impossible to help him !😱

Reeds throttle convention is forward for high, back for low - just like propo smiley

Thread: Electric control line with R/C ESC
21/12/2020 12:17:45

Hi John, for pennies you can buy a 2.4 pistol grip model car set from HK, BG, Ali etc which lends itself to a C/L handle conversion. Just a metal ']' shape from the top to the heel but make sure its well anchored!
Change the spring-centred throttle trigger to sprung-off (ie trigger outwards).
R/C aircraft ESCs dont normally have reverse but may have braking (some car escs reverse)

Cheers
Phil

Thread: TX history of frequencies and modes
12/12/2020 11:35:04

Hi Paul, as a young teenager I too was inspired by your book, at school the prizes were book tokens and I chose the first edition of "theory and practise" from which I learned an awful lot. I 'borrowed' a lot of your ideas for my home-brews, most of which are still working - so a sincere 50-years-late thank you from me!

Today's radios are generally 2.4 GHz and I don't know of any published DIY designs and probably not worth it.

Some of us try to support the 'E' in RCM&E and some like John question its value.  With the proliferation of RTFs you could equally say that scratch building is 'not worth it'! smiley 
There are many facets to this hobby and you're denouncing one on the basis that you're unaware that many of us homebrew on 2.4ghz. There are several published DIY 2.4ghz designs, and all current multimode modules are based on hobby projects. Whether its 'worth it' is down to the individual - on mode-zero right now for example is a project hatching which will combine all the transmitter electronics including encoder and RF into one module. Gary has stated that his interest is more in electronics than flying, so might find DIY worthwhile wink

Cheers  laugh

Thread: Hitech Optic 6 Tx
26/11/2020 12:43:14

Erm.... its a switch!

Easy DIY repair, its not rocket science... wink

25/11/2020 10:45:15

My Optic 6 also has an intermittent on/off switch, exactly as Robert described. Seems like a common fault!

Easy fix though.

Thread: Wing accuracy
14/11/2020 21:44:36

I've seen maybe a hundred Vic Smeed 'Tomboy's -- not one had a straight wing!
