Thread: Need a warbird without retracts
01/07/2018 18:04:00
Missing a warbird in the collection but the state of my local field rules out retracts.
Parkzone Wildcat looks good. Is there a Spit or P51 in this size?

I bought a Spektrum Tx this year but it currently has one model attached to it. My 6 year old Futaba set has 6.

Test flew in the calm between thunderstorms. Exceeded expectations. Launched on 20% power initially and then pulled it near vertical to around 150m. Stall and dive tests revealed CG needs moving forwards a smidgeon.

Hang time for a 1.5m glider is amazing. Weighs around 440 grams with a wing loading of around 6oz/sq ft. Funny how we mix units...

Little 2S 1300 battery gave me a 40 min dead air flight with 50% charge remaining.

First time with Spektrum. Liking the programming interface.

Never thought magnets would play such a part in construction...

Thread: Has Forum Activity declined?

Of the 35 members in our club, only 3 of us are Forum members. Not sure what that says, but that's the situation.

Interesting. Do you happen to know if the others use other Forums or Facebook?

I have the feeling that Forum activty seems to be declining somewhat. Is this just me, or does the data support this.
Me? I spend more time now on Facebook groups. Just wondering.
Thread: Electric motor not running with prop attached
22/05/2018 23:02:07
Haven't had an issue in the past. But this combo just didn't work.
22/05/2018 22:51:22
So...
My soldering skills were not the issue.
The Castle Creation ESC was not able to start the motor with the prop and had no programmable options to change timing or soft start parameters.
Swapped out for a JR enrg one. Ran faultlessly with a soft start and powerful brake.
Irritating to have to do loads of soldering and whipping the motor in and out. But got there😀
22/05/2018 09:25:46
Yes Alan. I'll remake the connections. I might hard wire them as space is tight in a glider pod anyway. ESC lets you programme the motor direction.
22/05/2018 09:23:39
Timing was my initial thought, but my Castle Creation ESC does not give TX programmable options.
22/05/2018 08:51:32
Setting up a drive train last night and came across an issue that is new to me.
ESC starts and runs the motor fine without the prop on. When the prop is fitted it runs for a few seconds on low throttle and then chatters and stops.
My guess is a dodgy connection between ESC and motor. But why would it run well without the prop?

Thread: The WORST plane you ever had?

MFA Hi Sierra, a 2M class glider.  Looked pretty enough but a beast to fly.

Tip stall city and terrible wing joiner arrangement.

Workshop heated a a relatively warm 16 degrees and kept company by The Cranberries.

Tailplane in Solarfilm So-Lite came in at only 12 grams, fin and rudder looking at around 6 grams.

07/02/2018 15:05:17

In light of the demise of Solarfilm - I hastily ordered a few rolls of Solite! Only 20g/sq M...

Simple, light but strong AMT that will fit on the Blaster V mount. Great wood selection from SLEC. In it's naked form (needs more shaping) it's just under 10g, and with covering and the mount will be smack on my 15g target. That's less than half the weight of the original.

Yep, even wings and centres are enormous these days. Watching some highlights of Jeremy Guscott twenty years ago shows the difference in styles and game play. He was silky, gliding through the opposition.

Now they prefer to batter into the opposition to gain turnover ball.

Still a great spectacle as that first hit goes in - whether League or Union.

I do think that things have got tough on all players these days with more body check type tackles rather than the traditional around the legs tackle that was taught when I was a lot younger.

It's the Rugby League influence, I think. It's no longer a contact sport - but a collision sport!

Always a great tournament and a nice transition from Winter to Spring by the time it concludes.

Scotland may be the dark horse this year - but it will still be an England victory.

PS
Let's hope this thread does not attract the "I hate all sport" type comments!frown

Nice model, as I remember they float very nicely. The only issue you are likely to have is achieving the CG - with a modern brushless and lipo powertrain you are likely to need a fair bit of noseweight. That new fuse looks a smidge longer in the nose though, so perhaps you will be ok.

Yes, you're right re CG. But a few factors work in my favour. The Pod and Carbon boom is very light - so the trick will be to build the stab and fin as light as possible and then adjust the boom length! The new fuselage will be nearly two ounces (54g) lighter - and much of that weight saved behind the CG. There is a trade off that with longer tail moment I can use a smaller tail. The SailplaneCalc design spreadsheet really helps here.
