A dream to fly with 2 Saito .45 Specials, 8 years old now.

Like mine,, 😇

Good luck with the locktite, it won't work, I have a couple of old motors with the same problem, one I drilled the exhaust port a little deeper and deepened the thread, now it is ok, another I have used the older technique that Rossi used for their piped 2 strokes, a steel ring with a spring around the cylinder head.

OK, so not so bad I thought but still a lot more expensive from UK sources.  Mind you not as bad as cigarettes - a neighbour told me yesterday that they're £16 for 20! Glad I gave up decades ago 👍

How do you get the cigarettes into the glow plug hole ?.

Has anyone built or flown this kit?

A club mate is just finishing one amd is interested in real-life flying experience of the kit.... he's asked F***b*** but I don't expect he'll get many sensible responses.

 

What weight did it end up at? 

What CofG did it end up at?

How did it fly?

 

TIA, GG

 

Looks like a nice cheap kit to replace my fading Hurricane, but with Brixit,,,🤢

Pinking is pre-ignition too hot and or mix to lean on petrol engines.

I found that the 'pitts' silencers ended up falling to bits in less than a gallon of petrol on the 20cc engines.

we heard a tingling sound

I was told it was 'pinking',

 

 Diesel Injectors, if my memory is right, were regulated as far as 230 bars on the 6 cylinder Volvo engines.

Any glow fourstroke will be a lot less messy than a glow twostroke,

As they only use half the fuel, or like me put some castor oil in the mix like I do to make up for it.🤩

Yes, most 4 strokes and 2 strokes will drop a few RPM's, don't worry about it, throw it in the air where it belongs.

Although we've never had a noise complaint, I have a self-imposed rule of nothing noisy (i

I was helping one of our members looking to find his crashed plane over 500 metres away from the runway

and was surprised to hear the prop noise of a small prop driven electric jet, whereas a bixler on FPV was flying around trying to find the lost plane was making little noise and could only be heard at less than 100 metres away.

[PTFE or not PTFE that is the question]

I don't know how what your needle valve looks like, but we used to put a bit of silicone fuel tubing on it as a sleeve, it stopped air leaks and unscrewing due to vibration.

Its 6 years into its set of bearings i think and its still fine

6 years means nothing, How many hours of running ?.

[Advice on Four Strokes for Newbie]

My saito's have been running for around 30 years, and only needing piston rings ( 3 x .45s and 1 x .45 std ) all run with at least 2% castor, I ran My Enya .90 and 120 on synthetic only fuel and they both needed replacement bearings in a very short time.

 

 Don't forget that I live in the south of France and fly mostly ever other day,,,

Don't forget the caster as without it your engine won't gum up properly 🤣

Yes, but without it, I will be going back to change the bearings on my 4 strokes every 2 years. 😡

[Advice on Four Strokes for Newbie]

Here we go again,,,😨

 100 pages on fuel,,,,🤢

 

Most fuels are good, a good all around mix for ALL 4 strokes especially the older ones is 10% nitro and 15% oil including in that a bit of caster.

The Dle 'canister" is worth a try on the Dle 20ra, it does quiet it down a bit and will give you a lot more power.

One of our members, who used to run a model shop, had a customer complain that the engine he'd bought wouldn't start and he returned it for assessment. It checked out OK and the customer took it back, only to return it again as a non-runner.  When asked to demonstrate his technique in the shop he applied the glow supply and said "There you are, it won't start."  He didn't realise it was necessary to turn the engine over by hand or with a starter to get the suck/squeeze/bang/blow sequence to start.  How he thought his car engine started, I can''t think!

The same thing happened to me, I sold a Citroën 1/10 scale car to the Citroën garage owner, his wife came back and forth as it wouldn't start, eventually he came to my shop, he put the glow starter on the plug and said there you are it won’t start, obviously he hadn't read the instructions and wondered what the bit of string on the rear of the engine was for.

On Saito, I have no personal experience but the grapevine says they're not the most powerful, so err on the larger side maybe

Yes, my FG-30 swings the same prop at the same speed as my Dle 20Ra.

I also have an HP .21vt, less power than a sewing machine, but cracking sound in the air and never stops, not like my *** Rcv, both gone, as ED said,

Enya 4c are really good engines 'if' you can get one.

 

Another 'tip' on 4 strokes is to leave the engine on its compression stroke, so that you don't end up with the valves sticking open.

[Advice on Four Strokes for Newbie]

Use a good oily fuel mix, an OS 'F' plug go for peak rpm on the ground then back the needle off 1/4 of a turn and put it in the air, no hanky-panky fiddling around on the ground for 1/2 an hour as it will overheat.

 

  The best 4 strokes that I have ever had were the OS .48 Surpass, and the Saito .45 S.

 

Don't even look at an RCV.😨

For me it would have to be a Saito FG21 which sounds nice and looks beautiful.

Big money🤢 maybe a Saito or other 150 four stroke methanal if you have a noise problem, did someone suggest electric ?.😡😨🤢
