Hi Keith,

Have you considered going for a 9x6 3 bladed prop.

Cheers

Thread: Air up/down retracts max system pressure
06/07/2020 19:12:21

Thanks Peter

It's the valve that came with the kit, I get the need for pressure to open the valve. The system is pressured from a 12v double piston mini pump the pressure gauge readings compare favourably with others.

Ideally I'd like to understand the max safe pressure I can take the system up to without damage and ensure the gear down is strong enough to push the nose leg down against the drag

I'm hoping I can get a little guidance.

I have a nearly finished 1/5 scale Phoenix Models PC21 DLE30 powered which is fitted with Phoenix air up/down retracts (supplied with kit). System is installed and working with no leaks. Can anyone advise on what the maximum air pressure in the system should be.

Before I connected the system up I passed air through the one way valve and it was reading 35psi with no load on the exit side, does this mean if I go to 100psi the actual pressure in the tank is only 65psi.

Thanks

Alex

Thread: Dihedral
03/07/2020 22:21:30

Hi Richard,

For what it's worth hi wing aircraft will have an element of self righting due to the pendulum effect caused by the weight of the fuselage hung below the wing. A low wing aircraft will have less or no self righting as the weight is on top of the wing and as soon as you bank there is no self righting effect as the fuselage assists the bank. With regard to the wing looking droopy the model in the image has a span of 82" has no dihedral and no sign of any droop

Thread: What size to print plans without a scale tab
30/06/2020 08:47:31

Most of this is probably covered above,

If your printer has a poster print option it will automatically print the whole full size plan on A4 sheet. (make sure fit to page is Not selected) if you use this method make sure the paper is well fanned out, aerated, the printer guides are as tight as possible and you have a lot of sellotape otherwise you'll need to fudge your jigsaw a little.

the other option and this depends very much on how complex the model design is is resize to make the plan fit on 4 a4 pages and scale it up as you build to size that suits you.

Call your local Kwik print type shop then email them the PDF and get a quote for a full size print

Good Luck with whatever you decide

Thread: What glues do you use?
29/06/2020 10:06:45

Main glues used are cyano, pva, contact and epoxy

Cyano - as a pin or tack in place then run over the joint with very slightly thinned pva dispensed from an old printer cartridge refill syringe and needle.

Pva - large surfaces

Contact Evostick - fuselage doublers

Contact Copydex - Balsa skinning foam wing cores

Epoxy 30min - firewalls, u/c plates, joining wings and with glass cloth for reinforcement

Cheers

Thread: Does anyone remember...
28/06/2020 15:35:40

In my defence I was only about 13 or 14 at the time and allowed to be an eejit on the grounds of age and given that I didn't remove myself from the gene pool Darwin Award doesn't apply .......... although it could have been a close thing.

Thread: Curving fuselage sides?
28/06/2020 14:59:27

Hi Martin,

i think you might struggle a little with curving the sides with or without the 1/16 sheeting, I'd be inclined to fit a triangular gusset to support the strip at the wing l/e. You could put the fuselage into the jig upside down so it's flat on the board and use some 1/4 sq strip to space the sides and form the curve required.

Cheers

Thread: Does anyone remember...

Thinking back, some of the things you did or could do quite easily then would raise howls of horror now.

In the early 70's when I was in my early teens I flew mainly control line combat pre Rossi & Super Tigre times. Pink Panther & Ironmonger days. (anybody remember them) Everything was covered in nylon and powered by PAW. I remember being in the garden shed (Dope, balsa cement and fuel proofed all banned from the house) trying to cover dope and fuel proof a combat wing in a single evening for flying the next day and having the bright idea of warming it up over a parrifin heater to speed up the drying process.

Fortunately no disasters occurred but when I think what could have happened ........... Olympic gold medal in stupidity

Thank goodness for heat shrink film

With regards to the u/c mounting plate, I'd recommend giving some consideration to using nylon bolts to attach undercarriage. depending on the size used you can deliberately create a weak point by putting a partial cut through the bolts. If you're unfortunate enough to have a heavy landing or dead stick into long grass the bolts will snap and the u/c will come off without pulling the mounting plate out.

Enjoying the build pics

Thread: Is the hobby dying/dead
24/06/2020 13:39:25

I think it's just a sign of the times and choice of recreational pursuits now available compared to what was available in earlier times.

If you look at what was available as a hobby/pastimes in the 60's and 70's there is so much more now. TV only had 3 channels and was only on from about lunchtime until early evening. No such things as cable or sky, videos, dvds, PCs, games consuls, tablets, mobile phones etc I could go on. Even within modeling, there were no artf, foamies, cheap radio sets, laser cut kits etc.

I think it's going to go a bit like bowling (absolutely no disrespect to bowls or bowlers intended here) I think there's a drift towards craft type hobbies amongst the more mature members of our society.

24/06/2020 11:55:04

I must admit I'm inclined to agree with the sentiments expressed above.

I'm a member of a small club membership is about 18 and of the 18 about 6 or 7 are regularly active. That said the majority of the others do turn up regularly come agm time and renew their memberships. Since the beginning of the year we have picked up 2 new members, one returning to the hobby and the other a complete newbie with an interest in drones.

With regard to modelling purchases I took the decision a few months back to stop making any significant new purchases and start using the engines that are gathering dust in their boxes. My last 2 builds were a plan built Chilli Wind and just coming to completion a scaled up version of a Rival/Big Easy by the same designer. They put a fair dent in my balsa and covering stocks but it could be argued I had far to much stuff squirreled away in the first place. The only regular purchases are fuel, few servo's, epoxy and other sundries. The other decision I took I only order from UK suppliers. I'll use HK but only if its coming from the UK warehouse.

Thread: Muffler choice
23/06/2020 17:12:19

PS meant to say, there's a couple of YouTube videos of the same combo if that's of use to you

23/06/2020 17:11:00

Hi Ted,

Ive also got a dle 30, as yet unrun and bolted into a Phoenix Models PC21. I binned the muffler thing that came with it in favour of a Pitts style silencer hopefully it'll be a bit quieter than the supplied unit. I've been trying to give it a run for the last week or so but I keep getting sidetracked

Cheers

Thread: Adding nose weight
23/06/2020 07:38:05

Thanks for the tip. Tbh if it was an abs/glass screw on cowl I'd be very reluctant to add this amount of weight to it. In this instance the fuselage and cowl are one piece traditional build. The fuselage sides stop at the back of the spinner top and bottom are 3/8" sheet shaped towards the spinner ring. So no danger of forgetting to leave them off.

I'll post a picture later which hopefully will clarify.

Once again, thanks to all for taking the time to contribute

Cheers

Hi Jon,

Thanks, I'm already there, the majority of ballast is fixed securely and I have some wheel balance weights on self adhesive strip that'll let me adjust the balance point between 25 and 30% of chord. So fingers crossed that should suffice.

Cheers

Alex

22/06/2020 14:29:33

The deed is done, 3 bits of 2mm lead sheet formed into shape and epoxied upfront inside the cowl. once it dries I'll glass over it just to be sure

thanks to all

Alex
