Thread: Well this could get interesting

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!

Some Lipo batteries come with XT60 connectors already fitted so this would be a good thing to standardise on ( XT60 are yellow) Motors often come with bullet connectors already 3.5mm I think- so again a standard thing so just buy the matching 3.5 female parts to solder to the ESC, same with XT60 just buy the matching half -they are marked + and minus. Correct polarity is essential!

The 3 wires from ESC to motor can be inserted any way round - if the motor rotates the wrong way just swop any 2 wires round.

For safety it is essential to get everything done BEFORE fitting prop - far too easy to have an accident otherwise. Even just going into the TX memory to see what settings had been done caused the motor to start up inadvertantly on my workbench - fortunately I was standing behind! You won't believe the instant power of even a small brushless motor until you experience it.....

Remember that your 40 year old engines might now be fairly valuable as Vintage engines!

Thread: Recommended First Balsa Kit

You could ( should) buy the Gangster 63 Lite direct from Mick Reeves Models for 95 pounds! Read up about it here and see that it is an improved construction now. No point in paying silly money for an old kit and anyway its already sold on Ebay.

Important to note that the original enquiry here was from a very experienced pilot and the answers are different to those that would have been given to a pilot of lesser experience. So it's quite important to build the model that will advance your flying.

Thread: Analog versus Digital servos
11/09/2019 11:59:34

I am sure Peter is right. Anyone with RC experience would surely have an analogue servo to hand.

But any 35 Mhz system will be quite old now and I would question whether it's worth paying to have it mended, 2.4 systems are so cheap now. Reliabiliity is surely everything in RC planes. If you must continue with 35 Mhz then it's likely that someone would give away a Futuba Rx or Tx that works well. Most of my club members have cupboards full of 35 mhz unused now but working. I would just ask around if there is anything going spare.

It can happen to anybody Peter! I had noticed that your static shot showed some down elevator while the inflight shot showed some up which made me wonder if the elevator was reversed or perhaps jamming.

Would it be considered sacrilege, in such a classic design, to suggest changing the LE construction to one using a false LE with separate upper and lower wing skins lapped over it with a front capping piece? To me that would be easier than trying to bend balsa right around the LE.

The original plan and article is on Outerzone if anybody needs it.

In the photo it looks like there is a bit of up elevator?

That's a rather large model ! I suggest a 1/12 scale version at 70" might be more economical but if your workshop is big enough for 70 foot........

Seriously, I can see what you mean about the 'scabs' on the plan - they look like sheet joining tabs to me. Tabs underneath to reinforce. No cyano to join sheets in 1963. Nothing in the instructions to explain , but instructions on rolling the sheet suggest it needs very wide sheet.

SLEC used to sell sheet wider than 4 inches.

Phenolic trim bar would appear to be an ancient  ( pre modern radio with trims ) way to trim model.

That's a pity with a new model - we all know the feeling! Doubtless you will have it all sorted out soon.

There is a cowl available for this model from Sarik if you need it.

There is no article it was just a few lines in Colin Fretwell's column - I have quoted all the relevant info.

Martin, I have sent you the copy of the article.

As regards the flying characteristics of Miles Hawks - one of the negative comments was by Phillip Kent in his scale column in RCME Aug 93 - he said "The Sparrowhawk and the Miles Speed Six have presented problems to modellers in the past. The low speed flying characterisics have not been good and a fair number have succombed to tip stalling........... with a thinner wing and some washout I am sure that a new model will lose these viscious faults and become a much sweeeter flying machine"

Of course he was talking about the Sparrowhawk and I notice that the 3 view he showed ( his own and he said more accurate 3 view than others) does not have much of a flat centre section. Also the Sparrowhawk fin looks smaller than the Lockwood Miles M2X in the photos in RCMW article, so maybe you should not worry too much.

Mike Delacole has already produced a larger Chilli Wind as a .60 version. I don't recall it ever being published. This larger version was mentioned in RCME August 1993 page 29. Doesn't mention span though.

Also mentioned was the fact that Mike had modified the Chilli Wind 40/45 by increasing the tail moment by 3 inches and nose by 1.5 inches. It said anyone interested in this version could phone Mike - presumably he supplied a new plan, maybe for the .60 version too. I would guess that the 60 version was also increased in tail moment too. RCME published a phone number for Mike but it's unlikely to be the same after 26 years but I will give it to you by a PM if you want to give it a try Alex.

I reckon that if you put a ruler on the plan along the aileron hinge line ( in plan view) from where the torque rod enters aileron to the exit point for servo it will show just where the TE is grooved and that it's possible. Also in edge view a line along the aileron hinge line will just come inside the wing lower surface at horns for servo. Thats the way it looks on the tiny plan - it seems possible - just. And the strength will not be affected because of the ply part.

01/09/2019 19:11:15

Looking again ( with a magnifying glass! ) it seems to me that the deepest groove ( thinning) of the TE is strengthened by the 1/64 ply inserts (? 1/64 the print is so small) just at the point of maximum depth of groove so that should be OK

A further look at the small plan suggests the torque rod should have been drawn a bit straighter and should show that the groove is dug deeper at the dihedral break and gradually gets shallower at the centre. Also that as it must be at aileron centre then it would come quite near to the lower surface at centre section servo. But it looks quite possible with some balsa digging and fitting the TE around the perfect line for the torque rod. Of course to work properly the rod must go along the aileron hinge line and the bit into the aileron must be a 90 degree bend into the aileron ( not as shown at more than 90 degrees! )

Martin, if you want a scanned copy of the article send me a PM with your e-mail address.

If it is the MW3129 plan at 48 inches by John Lockwood then it's in RCMW Jan 2005 . I have the magazine and it says the aileron torque rod is located in the false TE which is grooved to take it.  It appears from the small plan that the torque rod is straight and its accomodated in the TE in the centre section by putting the groove in that bit at an angle.

I am sure I have read that Miles planes don't fly well because of the small tailplane but I am not sure where i read it - worth checking with someone who has built one. Maybe this one is not scale, the writeup seems to infer it flew OK.

Which RCMW Miles Hawk is it? If it's the Philip Kent one MW3117 then maybe ask the designer - you can see a phone number for him on his clubs website where he sell his plans. Maybe the drawing does not show the actual line of the torque rods but is an error. Errors always seem to be draughtsmans errors not original designers errors!

Mini servos were around all the time RCMW was published although quite dear in the early years. But wing servos would be easier if you put the servo extensions or tubes in at an early stage.

Rumour has it that Miles planes don't fly well in smaller models.........

There are not many books on aeromodelling still in print, but one that is available secondhand and a bargain is this one by David Boddington.

If you find the Solarfilm covering video you will find the techniques work on the film covering sold by HobbyKing.
