Thread: My idiots guide to 2.4 ghz radio - finally bit the bullet and upgraded!
15/02/2020 12:57:41

Well most of our rc equipment comes from China so If we ship it our selves thats each persons risk and it easy to get the revelent info with out needless speculation.

See this direct link about the FS-6i compliance from Flysky web site it is all you need

for other radios see including the great Paladin PL18 Here and each RX there to

as for the radio flying on a budget it is a good deal Fly sky make good reliable gear

The Ce  sticker means that the manufactuer is stating that it complies with eu regulations anyone can stick it on but a certificate to back it up is required too.

So Op (Bonzo) you can fly now without speculation now laugh

Thread: How wings generate lift
13/02/2020 17:25:49

Well that is old theory and keeps being repeated by tv etc, wind tunnel tests have showen that the air that splits at the leading edge some going over and some under dosent actually  reach the trailing edge at the same timesurprise .

The air under the wing is compressed slowing it down and pushing the surface up see this for proper show

Its the compression thats pushes you up not the vacume sucking you upwink

And I thought it was done and dusted by now

I have seenit on ytube looks very good I've been tempted but sercome stance has not come around.

I think you have spelled it incorectly spelled see Glocknerhof on ytube if I'm correct looks fantastic location

Thread: Charging Nimhs
31/01/2020 16:52:59

i find 400mah a good all round charging figger for nimh packs for Rx and TX's.

When i have had false peak detect charging problems on two ocaisions it was a bad switch, another time a poor connector (all having slightly higher impedance than a good version

and you also get problems when you have a doggy cell in the pack which has happened to me only with new or just about new packs.

if you can get to each cell and test voltage if you have a doggy cell it will have a lower voltage than the others after a little use. To get at the ends of each battery without ripping the nice shring wrap I use small pins to pock through the insulation tto make contact with the terminals.

Only last weekend a new member lost his trainer due to one cell failing and the anoying thing about it he was on finals and litery only needed 2/3 seconds of power and all would have been goodsad (battery was checked on first flight and this was the second short flight)

Thread: Peel Ply Issues

As with all 2k paint or promer you must use a good mask and have good ventalation if you can smell it a mask must been worn!!

long turm exsposure is no good, but with the right mask and ventelation good to use in our small quantities.

Alternative available from here

and the same as posted above on ebay but with spay gun thinners required for both to spay

At the moment I am using EL2 laminating epoxy which is excellent and wet outs very well also from easy composites i use there 25g cloth which is very good to

I would use the slow hardner for laminating large areas. If you are a well practiced laminator and quick at it the fast hardener is ok too.

the trick with light laminating is to use just enough resin to 'wet out' the cloth

30/01/2020 10:08:44

It could be the fact that to much resim has been applied and has't been sqeezed out, use a soft sqeegee (works better than a credit card) from the centre out to get rid of exses ressin then do the peel ply and rub over, finniish will have the texture of the peelply cloth.

The bubles in the resin can come from the wood you are laminating over, also bubles are formed when mixing and don't exscape due to cold ressin.

i do think as the fact that you were fine befor and that this time you have used a sponge could be the root cause

29/01/2020 19:47:31

well composites are complicated, what are you using would be helpful ie info on ...epoxy / polyester/phenolic resin , the cloth used and method use would be helpful to give useful infomation(temprature of room your laminating in?)

as for pin holes your not laminating correctly and it's not a peelply effect

?

Thread: Petrol conversation
23/01/2020 11:33:29

What's the reason for wanting to convert these engines to petrol, is it cost of fuel or just an interest?

Running these engines on petrol will have less power as they are running on methanol now.

with the smaller engine the extra weight of the ignition and battery will probably be a disadvantage.

I would keep them on glow and use a modern fully synthetic glow fuel with a low oil content to keep the mess at bay

as for the saito is it the twin plug version? that will be a problematic conversion.

If you really want a petrol engine sell what you don't want and buy a purpose built petrol engine

just my thoughts on going through all the other attempts and including mine are problematic

Thread: 2k aerosol laquers
07/01/2020 22:15:23

If you are using 2k spay cans make sure you use the one (proper 2K) that has a hardener release valve on the bottom of the can(once activated usable for 7 hours)

But in your case don't as you have used enamel, if it was just sealing the solartex from getting grubby it be good.

I would use a very light?thin coat of epoxy lacqure see glaskote available i believe from fighteraces in the UK.

Thread: JB Weld
18/11/2019 20:14:05

JB weld will work just remember to mix accurately and well and where you want it stuck lightly key the surface and make sure it grease and dust free.

used it a lot on that Hanriot of mine cabines and undercarriage parts takes a week in a warm place to competly cure to full strength ( ie 90 odd percent on a day rest over a few days

If you download 170317 firmware you will see when you unzip it the folder will contain two files one eu the other not

 use the eu frk file and all will be good  ( xjt eu170317.frk  )

Thread: Charge rate ???
10/11/2019 18:50:57

your charger is 80w max thats your limiting factor, get a better charger that can do more amps ie 80w at 6s pack is about 22 volts so 80 divided by 22 gives 3.6 amps approx so so 6amps x 22v equals 133 watts so look for a 150watt charger or better.

hope that these basics calculations are helpful v a and watts are all relevlant to each other. any q's just post some more

Thread: Twin petrol engines
03/11/2019 15:50:43

first thing to check is what you ingition modual voltage range is , most modual these days are 4.8 to 8.4v so can take 5 cell Nimh , Life 2s or lipo 2s with no problems. if using Nimh use sub c bateries so there is little volt drop when loaded.

There is no problem using 1 battery pack for two engines and one opto isolator on a y lead feeding each ignition, just check current draw requirement can be handeled by the chosen battery pack and isolator.

i use these i becs as are good and have a regulator to keep the voltage constant, bit on the more expensive side but they are good and reliable.

Polyester will melt polystyrene foam , don't use the auto motive resin for laminating get a good laminating polyester for that job it will be stronger and lighter than the automotive stuff as that tends to be low grade and will have fillers/thickaners in it too

a lay up of epoxy will be a lot lighter and stronger than polyester but it might be ok for your application.

plenty of models have been made from polyester with good results being cheaper t so easer to sell, while a epoxy version will end up lighter /stronger and more expensive.

take your pick but choose the right foam.

 P.S  epoxy left in a container or in a large lump will heat up and cause a potential fire bit slower than polester but still a big caution to be considered

Thread: Best light wind slope soarer
28/10/2019 17:46:57

Any decent light weight glider will do . i have used my dlg (an old longshot 4)for very light winds giving it a spin launch out over the slope to see if you can stay up and if not you got the height to get back better than a e motor as no weight handycap.

You could look for a HLG hand launch glider) or F3j type gliders see the top model range of gliders see what hyperflight sell to get an idea
