Sig Four Star 120 Engine Choosing
I'm considering a gas engine for the sig four star 120. I'm leaning toward the DLE 20, but want to consider the DLE 30 as well. I'm also considering down the road, if I were to move the engine on, the DLE 30 might have more airframes from which to choose. I have no experience with either and appreciate any suggestions/comments.

I've seen aeroworks already has a plane with the DLE 20. Cool beans. [8D] Right now it seems that the 20cc is fitting in with .60-.100 size airframes(I may be wrong). But there just aren't many of em from which to choose, imho.

By moving the firewall the 4* will fly nicely with up to a G-38.
If you cant move the firewall, then the DLE 20 and careful selection of components would make a great sport flier (not torque roller)
A lite 4* will float forever and many people remove one bay from each wing to make it more sportier.

sounds like DL needs to bore-out the 20 and add a 26 to their list now

Windgap,
I have a 4**120. I initially put a 3w-24 on it and I was disappointed with its performance. It flew but not very exciting. The 3W-24 is close to the DLE 30 in power. I finally fit the plane with a 3w-48 twin with a 3 blade prop (due to ground clearance) and the airplane really became fun to fly. Very stable but fun and not quite unlimited vertical.

I have a hard time contributing to the demise of a fine company like Sig, by buying one of these.

Actually most small twins are a little on the heavy side but very smooth and vibration free. The same is true with the 3W-48. Good power but a little heavy.

I don't think you'll find a shortage of planes for either engine? If anything, it looks to me like the 30's are harder to find - though there's a lot of brand new stuff surfacing - as long as you're interested in aerobatic types? I would be inclined to think you would make your choice on which to go with based on what you're looking for in terms of raw performance? If you want an engine that's capable of throwing the plane around like a rag doll, go with the 30. If looking for something a little more sedate, go with the 20?
Punched out 20, now there's something to look forward to. Maybe perfomance approaching that of a 30 - but 8oz lighter? Bring it on! Where do I sign?

I have a 4 star 120 with the DLE 30 on it. I can not imagine anything smaller. It jumps off the ground in about 4 to 5 feet and goes like is tail is on fire. When its time to land it will just about stop in mid air. A great flyer.The only mods I did where to make the firewall 1/8 inch thicker and pin the firewall. I moved the batteries around to get the cog right. Everythin else is stock. Oh I did put counter balances on the Elevator and rudder. When I mounted the engine I had to make a small cut out for the muffler. Unfortunately it is out of out of commision right now. A friend crashed it and broke the fuse in half because I had the wrong servos. I now have a new fuse kit coming and metal gear servos waiting to go in it.
I hope this helps,
Alan

When they charge $150 for a Four Star 60 kit like they are doing right now, it is not a matter of contributing to the demise, they are toast at this point sadly...

RE: Sig Four Star 120 Engine Choosing
Sad that kits are more expensive that ARFs although I still prefer to build a kit myself than buy an ARF.
If I build a Sig Four Star(which I have, the Four Star 40) I know how it was built and I can make mods.
I like Value Hobby and I've considered buying some of their ARF kits, but not the Four Star "knock off".
But wait...the Stylus kit appears to be a bit different than the Four Star...it appears to have a fully symmetric wing...the Four Star has a flat bottom wing, if I remember correctly.
I wish Sig would make a 120 size version of the Somethin Extra!
In any event it is sad that kits are more expensive than ARF's.
