Some people might worry about their lives being a little shorter due to pollution by planes and cars etc. Hwever within that (shorter?) lifespan we can at the moment see and do so much more than previous generations. Many ordinary people have seen more of USA than explorers Like Lewis and Clark, more of Africa than David Livingstone and seen more than Capt Cook.........

Well it would appear that is the way it's shown on the Wot4 electric modification! But the cable ties would seem to go out at an angle and a large gap would be available to get cutters in without touching the Lipo. ( ply plate is wider than lipo and it is notched to take cable ties ) But Erfolg is right to warn about any possibility of cutting into a Lipo and causing a short circuit which would be dangerous.

However all my own models are fixed with both Velcro patches and Velcro ties ( 2 for a 4S3000 ) which has worked well when mounted above the ply ( the method for Wot4 and possibly the Corben Super needs the Lipo to 'hang' underneath the ply which might mean cables ties are more secure)

Paying them the Minimum Wage seems over generous to me!

Directors of companies that go bankrupt should surely have to pay back anything they have received over the Minimum Wage!

The two possibieways of fixing the Lipos to ply are

cable ties and cutting away each time and replacing.( might be more secure and cable ties are cheap ) Or use a separate ply plate for each Lipo.

Velcro on battery and on ply together with velcro strap right around - belt and braces. Ply should be treated with a coating of epoxy etc and left to harden before using self adhesive Velcro. ( Self adhesive easily pulls off if the surface is not smooth)

Well nobody has replied yet....... ........ One idea you might consider is one that has been used by many people on different models ( Wot4, SLEC FUN FLY etc) is to use a removeable ply plate with a tongue that slots into motor bulkhead and a bolt at the other end to secure into a captive nut.  Battery is held to this removeable ply carrier plate with velcro straps. Ply plate goes in at an angle from underneath, so the access hatch is underneath. It might mean connecting up when model is inverted - maybe needing a simple stand - but it saves hacking the cowl around.  This method is shown on Chriss Foss'  website and maybe he originated the method.

When making this type of u/c mounting I always saw the slot slightly undersize and then run a drill of the exact size through afterwards.

It's a bit unfair to those of us who buy RCME at WH Smith etc - maybe David Ashby could change this one item? Because if we don't buy from WH Smith but subscribe then RCME won't get the exposure to newcomers who look in newsagents! Result less subscribers in the long run?

The problem with using 1/16 Liteply for a fus doubler could be that it won't bend in at the front. However in this model the doubler is straight up to F1 and actually should stop there as the top view shows it tapered away at the cowl. So Liteply would be fine and stops at F1. ( fuselage side view shows doubler extends to nosering but this seems incorrect/ unnecessary )   But 1/16th Liteply does not seem to be stocked by SLEC or Balsa Cabin so 3/32 /2mm is the thinnest available.  2mm might be hard to bend for other models but would be quite OK for Werewolf as it does not need to bend - could be a little heavier though.

Have you fitted the Bind plug when trying to bind?  ( Bind plug for Spektrum is a Rx plug with a tiny streamer attached)

If you cannot get in at a club note that most clubs are full at mid summer but by next January there is likely to be places available in a typical club. Ask around December onwards! ( all BMFA affiliated clubs have a year that starts January normally)

By my calculations that amounts to about 35 pounds worth of balsa and about 10 pounds worth of ply at SLEC prices.

The 1/32 birch ply fuselage doublers are about 6 pounds but probably worth their cost in allowing a crashed model to be repaired in many cases. Compared to -say- an original balsa kit built Wot 4 that didnt have 1/32 doublers ( just minimal ply reinforcement) that usually destroyed it's fuselage in a hefty crash it seems worth the cost!

19/09/2019 16:05:22

A quick estimate would suggest you need -

Balsa by 36 inch

!/16 by 3 qty 4

1/16 by 4 qty 6

3/32 by 4 qty 5

1/8 by 3 qty 2

1/4 by 4 qty2

1/2 by 3 qty 1

quarter sq spars qty 4 rock hard ( personally I would use spruce )

1/4 triangle qty 1

3/16 sq strip qty1

3/8 by 1/8 TE qty 2

3/8 by 3 small piece for cowl 5inches

1/8 Liteply 19 inch by 3 inch

1/32 Birch ply 20 inches by 8 inch

1/8 birch ply 13 inch by 3 inch

1/4 birch ply 16 inches by 1.25inch and 3 inch by 4 inch

Hardwood 3/8 sq for wing servo bearers -16 inches and 1/4 sq for servos 8inches

Hardwood u/c blocks

1/4 dowel

8 SWG piano wire

All that as a minimum but don't blame me if it's wrong!

The build article is here on the forum. And there is also the forum article here.

Peters article on estimating balsa is worth reading as i recall but it's "subscriber ony" not for people who buy RCME from WH Smith !

The way i estimate quickly is to get a sheet of 3 inch and a sheet of 4 inch balsa and try them over the plan components. Put the sheet over ,say, the elevator -move a thumb to the tailplane & elevator end then put over the fin, rudder etc and see if it all comes out of one sheet or needs two. Also checking whether 4 inch or 3 inch is needed. Jotting this down and the grade ( eg light for tailplane parts) Then I do the other 1/4 parts - formers etc to see if they would come out off the sheets too.

Same with the fuselage and wings remembering there are 2 fus sides and wing halves, and top and bottom for wing sheeting. Probably another sheet for fus top and bottom which is easy to forget. Then I get a wing rib shape and see how many times it can be fitted on one sheet so by counting the ribs ( both wing halves!) I know the number of sheets needed. Then it's a matter of looking at the other 1/16th parts to see if they come out of the offcuts or need another sheet. Always over estimating and being generous with material needed.

Then I look around the plan for all the wing spars , TE and smallerparts plus hardware like piano wire jotting it all down. The I have a list and need to add a few sheets for mistakes/ under estimate etc especially if paying for postage and don't want to pay for a second batch.

So I do all the 1/4 parts, then the 1/8. 1/16 etc in turn. Maybe the 1/2 parts need a sheet or maybe they can be laminated from the spare 1/4 sheets. Then its a matter of looking around the plan for any odd size balsa or overlooked parts like 1/32 ply doublers etc. and especially for balsa spars etc.

Somewhere a couple of years ago Peter stated a list of balsa that would make almost any of his designs........ having that material always in stock is a good idea.

You could disguise the repaired patch with some clever coloured trim on both wings to look as though it was built that way!

Cheaper too ...sheet balsa is now expensive!

Thread: Irvine .53 / Ugly Stik

If you really want to resize a model and draw it in CAD there are so many desgns you could start with - but is it realy worth the time if plans such as the Rival are so readily available?

However one design that might be worth drawing to a larger size is New Era 3( the revisited version) - if you read the article on Outerzone you might consider the design is worthy of being larger by maybe a third at 55 to 60 inch. ( note it's only the New Era 3 that has such a good reputation and the Revisited version is slightly modernised )

Thread: Aileron Thickness

Presumably D.A. Scott was talking about the aileron hinged edge being rounded whilst Don was talking about the TE.

And I also think that Don was talking about the author of the book being an idiot not Capt Kremmen! ,

How far out does this jamming work and will it affect legal flying at normal flying sites? Forecast is beautiful flying weather tomorrow, so will we see a spate of unusual crashes at club sites? Maybe 35Mhz might be safer!
