Was wondering what size of engine people are putting on these planes. I like to build around OS .25FX. Has anyone used this engine combo.

in 1/12 aces combat the FW190 must fly with a .15 engine and pull a streamer. A .25 is a bit much imho.

Thanks for the info. Am not looking to do combat all the time. Our club its combat run what ya brung! Do you think that .25FX (I need light speed!)would be okay weight and balance wise?
Thanks for the fast reply

balancewise, it's up to you to place components where they bring you the tightest turns and slow landing speed. The plane will fly just swapping the engine. It will fly better after trimming.

What I really want is to build this plane to go as fast as can!!!!!!!!!!!!!!!. We fly combat just for fun. We really don't use any rules. I know an .25FX in the great planes combat p-51 goes like hell flown a club members last weekend. If anyone out there has built this FW190 with a .25FX let me know how it went. Or if you built this kit what type size engines have you used.
Thanks for the help

Then I suggest you put the .28 MVVS in it.

Thanks for the info I will check into that engine.
Have a great day.

An OS .25FX will work fine. I haven't seen an FW190 recently, but I have seen several other 1/12th kits run with that engine or other .25s and they do fine. If you want to go REALLY fast, get a Webra .25 and a mousse can or other tuned exhaust. At that point you'd be getting close to where the structure may fail though.

I built two of these kits when they first came out. The first had an OS.15FP and it flew well, but didn't have enough power. The second had an old OS.25SF and it was just about right. They both needed a LOT of nose weight to balance them, so your FX would actually help in that department.

My advice would be to install the OS.25FX with a 9x4 prop, reflex both ailerons up 3/32" (reduces tip-stall) and have fun with it.

HTH,

Thanks for the great info!!!!!!!!!!!! I love speed lots of. Our clubs motto is "if it isn't overpowered it isn't flying." I always try to build around the .25FX for the price it's a monster. Thanks once again I really appreciate it. I grew up in CT when I go home I fly with my pop at Quaker Farms in oxford we use to fly at shrewood island in norwalk. were do you fly?

PE is in the Netherlands where they fly ACES rules and they are limited to engine, prop and rpm limits, so they don't get to play the same overpowered version of combat that we enjoy over here. They build light balsa models, stick in good runnin 15's and have at it. We started with 15 powered combat over here, used catapults to get up in the air and after a season or two were flying 25 sized armoured rockets, it's beautiful.

Fly whatever combat is local to you man, it's all good. But the 25FX in a JK Aerotech FW190 would go like snot and be pretty resiliant.

A warbird with less span than 12meters (39.4') must be flown with a .15 over here. (Aces rule)
construction is either balsa(light,strong and explodes on impact), foam (resilient but not durable), or as I do, a combination of both which is very strong, lasts forever and impact resistant if clad with wet paper and waterbased floor board polyurethane. Weight is typically less than 900 grams (32oz). No decalco's needed, because all can be printed on the paper that is used for finishing. The urethane paint is very fuel resistant.

For brute power without weight penalty in a .20 sized housing, and disregarding rules, there is no engine that can beat the .28 MVVS with black mousse can type muffler, unless you want to pay double or up to quadruple prices for racing class engines.
Mortality rate (half-life time) is quite high in Combat, so I would not use my super class engines for that. Prime considerations are quick starting (first dab of starter), quick power-up and high crash resistance with low cost small parts.

I would definately go with the .25 FX. The Webra and especially the MVVS can be finicky. They do run very well but with the OS you know if you put it in it will give you no trouble. Also on prop I would use an APC 9-5. The current active combat guys tend to go with less pitch to get the engine to come on to the mousse can "pipe". Unless you put on a pipe yourself the 9-5 is the way to go. Also you will probably get recomedations to use Master airscrew props. If you want speed go with the APC.

If you are going to buy an engine and plan on the 25fx, I would get the 32sx instead. Fits in the same mount has more displacement!!
