Default Top Flite FW190 Engine recommendation

Hi everyone,

First of all introduce myself...

I have been flying for more than 10 years, mainly aerobatics like Extra and so on....not a very good pilot because lack of time...anyway I enjoy a lot

Since a couple of years ago I got in love with FW190 from Top Flite which I bought last month...and here goes my great doubt:

Once I saw a few you tube videos I was almost decided to go for the new SAITO FG90-R3 but after reading in different forums I am totally confused. This would be my first 4T engine and I see plenty of issues describing malfuntion of this engine and temperature and piston problems....so is there anything similar in power and "that amazing sound"?

I have thought about Valach or 3W but I would have to start to look and get info because I have no idea about them

That said, I would appreciate any comment, segestions or ideas...

Thanks in advance

Regards

I'm currently running a FG84 in a TF Corsair that was modified by Ray English. He had a big problem early on but since it was fixed the engine has run strong. My main concern now is enough prop to bring down the revs in flight because compared to static rpm it's unloading as much as 1500rpm in flight.

So so if you want the new FG90 then I suggest getting telemetry on the rpm so you know what it's doing and you keep the revs in check.
Otherwise the DLE 55RA and the 61 are the way to go. I flew this same Corsair with the 55RA fr a while and it's fast and sounds great. If you go this way put a Xoar 22x10 carbon prop on the 55RA.
Ill be testing the DLE 61 with a 24x12 later on in a TF P-40. Either DLE engine you can't go wrong.

If you have to have a 4 stroke then another option is a Roto motor. Look at the CAD drawings they have to see which engine fits the cowl diameter.

The mod FG84 is turning a 24x14 over 7000 rpm! So I'm going to switch to a Solo three blade and 24in blades. The sound is pretty awesome with the Keleo pipe but I hear they are not being produced because of health reasons.

Hi again, continue confuse.
What do you think about 3W or EME?

3W engines are pretty nice from what I understand, I've considered them before. I like parts support and availability so I tend to stick with brands like OS, Saito and DLE for the most part. If I see something else I gotta have then I have to really see if there's other choices in engines and weigh the pros and cons. I tend to look at the specs for compact light weight and highest power in most engine types because I fly mostly warbirds and hate engines sticking out of the cowl.

So Roto is very interesting to me because they got the head design right. It's been designed in Solidworks and the flow of the head has been studied using computer fluid dynamic analysis. The intake is opposite the exhaust like full scale engines for one. So for your FW take a look at the big twin they offer, 85cc I think, From what I remember it should fit in the cowl but take a look at the drawings of the engine for the overall measurements. If you printed them out at 1:1 scale you can place the cut out of the engine in the nose to see what's going on.

I have a SiST FW kit I'm waiting to build and I'm seriously considering the Roto engine over the Saito twin gaser.

3w are heavier but good engines

The FG-90 R3 has been modified by Saito; the mods are similar to the Ray English modifications on the FG-84 R3!

The EME 70 is a good choice for that plane, plenty of power, smooth and can be had with a starter which is very nice. At half the price of the other engines it is a nice bang for the buck.
Having had experience with the Saito radials I would not touch them with a ten foot pole right now, not designed correctly for gas and pricey to boot.

Forget about sound and go for simple and reliable. DA 60 or DLE re 55.
IMHO

Funny thing,
I've seen just as many people have problems with their 2 strokes as compared to my 4 strokes.
The sound of the 4 stroke really doesn't have any reliability drawbacks in my experience.

Thanks a lot friends...

I guess I will forget Saito due to all the problems they are having...I do not feel like flying afraid of motor stops or problems...

Yestarday I was taking a look to the Valach 70 but cannot find too much info and do not know abuot its power, about sound just one video...Another option is the Zenoah 62 but is hevier and not the most powerfull one.

Its logical to think that sound it is not as important as reliability; and I think so too. But I think this replica planes should sound as posible similar to the real ones, so once you see it pass low and at high speed just 5-6m from you you get impacted by the tremendous noise impactation...

As Chris Nicastro said, I am gong to look for info about the DLE61.....

Thanks a lot and I see most of you are from America, you guys usually respond while I am sleeping here in Europe::::::)))))))

Good flyghts

Ona last option friends,

What do you think abouet de Valach VM85?

Will it be too much for this plane?

Very expensive but not much more than the SAITO.

If the cowl woll fit it, look at the 70 twins, eme, da or valley view. Much smoother and more torque for bigger props.

This would be expected as Ray English has been under contract as a consultant to Saito to make recommendations on new engines. Sounds like they are listening to him! Leo
