The TT Pro .46 would be a terrific engine in a Tower Trainer 60 ARF, a Thunder Tiger Tiger Trainer .60 Mk II ARF, a Hobbico Nexstar 46 ARF, a Hobbico Hobbistar 60 ARF, a World Models Worldstar 40F ARF, or a World Models Super Frontier Senior .46 ARF. The shortest wingspan on this list is the 67" WM Worldstar 40F. The WM Super Frontier Senior 46 should look very familiar to folks who have flown the Sig Kadet Senior.

Anyone who says the TT Pro .46 would be underpowered on any of the above trainer ARFs simply hasn't tried it before.

The TT GP-42 is a better match for true .40-size trainer ARFs like the Avistar ARF, the Tiger Trainer .40 MkIII, the Tower Trainer .40 MkII ARF, or the WM Sky Raider Mach I. The GP-42 has gobs of power; 13,500 rpm slightly rich on a 10x6 Master Airscrew Scimitar S2 prop with a Fox RC Long glow plug and Magnum 10% nitro fuel with 70/30 synth/castor lubrication. The more expensive O.S. .46 LA will only turn 12,000 rpms or so with the same prop, fuel, and plug. The light weight of the GP-42 will make 59" to 63" trainer ARFs balance more easily and maintain the gentle slow flying characteristics of the airframe without cutting out power.

Good luck and good shopping!

Ieven used a GP42 on my Escapade ARF and loved it.

I have seen them there before as well, but something just smells very bad there. I have read that they are indeed Sigs airplanes only with the Sig name smudged out. Not sure what happened betwen Sig and its ARF builder, but I would feel icky buying one of those LT-40's with the Sig name smudged out. Thats just me though.

whats in a name?

if its the same plane its the same plane. Forget the badge engineering

Sounds like with this engine I can go either way with a 40 or 60 sized plane. I like the looks of the Hobbico Hobbistar 60 ARF, but while reading about it, I read some guys comments that because it wasn't covered in monocote, he would stay away from it even though he really liked the plane. Should I be avoiding some planes because of the type of covering on them, and if so, what coverings should I be avoiding?

Whats in a name? I would say alot! I have a Sig Rascal 110 in the hangar..a Sig Hog Bipe...a Sig LT-40...currently building a Sig Kougar. I have owned a Sig Rascal EP, Sig Komander, Sig Kadet, Sig Spacewalker etc. etc. Maybe it is just me, but something just don't seem right with buying a Sig designed aircraft that has the Sig name smudged out. I am probably in the minority though and I know most folks are probably ok with buying an LT-40 at half price without the Sig name, but I always have a soft spot for small american business trying to compete against foreign competition. I don't want to start an arguement here and as I said...I am probably the only here that sees a problem with buying one of those LT-40'S from nitroplanes, but Sig has been a giant in this hobby for years and have put out some darn fine product over many years. We should want to see a company like Sig remain viable for many years to come. I think it is ok for most folks if everything goes overseas, but lets just keep at least one or two good ones around here please? Sig is a good one and if you have ever owned a Hog Bipe or some of the other great Sig planes.....well this hobby wouldn't be the same without them!

Well, I just placed my order for the LT-40 ARF at Nitroplanes. The plane is what I was originally looking for before I read all about Sigs ARF problems and became unsure. So now I'll take a chance on it anyway, and the price was right. I also got an extra 5% off using the NITRO5 coupon. Before I ordered, I read every single review of the LT-40 ARF here at RCU, and everything was so positive for this plane being just an awesome trainer AND a fun plane to fly even after someone is experienced, that it made up my mind to just do it. Thanks to everyone for their advice and opinions. It's great that the people at RCU are definitely more than willing to help a newbie out.

Oh, and BTW, the 70" wing will fit kitty-corner in the 5ft. bed of my Tacoma with about 3 inches to spare. Boy, you just gotta like it when it all works out

Blacktails you made a wise choice. The LT-40 is a long time favorite and a perfect match for your 46, that you will not regret.

As far buying it from Nitro you have no apologies to make and it would be silly for the fellows who really want them to deny themselves of this last batch because of the problems that Sig may or may not have with their suppliers.

I too consider this an unfortunate blow to Sig, a long time favorite with many and sincerely hope that they get whatever problems worked out and become a great supplier once agine.

Idoubt SIGwill be in much of a hurry to carry ARFs again after this last fiasco. That said I do not begrudge you buying one from Nitroplanes. As it sounds you probably would not have bought a kit anyway so it affects SIGnot at all . In the future after you have had a good experience with your SIG designed ARF you may consider kit building and give them a chance.
I think you will be very happy with any SIGkit you choose to build.

Although I advised against buying it from nitroplanes..the fact is that the LT-40 is a great trainer airplane regardless of where you got it. Your TT 46 will pull it around nicely and it is as big as some 60 size trainers. Good luck with the LT-40....I am certain you will enjoy it![8D]

I have built the Sig LT-40 from kit and it is a very nice building kit like all the Sig kits I have built except for a couple. The Sig Citabria kit is not for the faint of heart and the Sig 1/4 scale clipped wing Cub can be a good challenge, but all the updated newer kits from Sig all build very nice and something like the LT-40 kit would be an easy first build for anybody wanting an LT-40. Goes together very nice with great instructions.
