kit for .25 engine??
 

I have Magnum .25 engine and don't know what to do with it....any kit that you would recommend?
How about Great Planes Taylorcraft 20??

I don't know what your building experience is. However, the July 2007 issue of Fly RC (Issue #44) had pull out plans for a plane called the Blue Flash. It's a scratch build, but it looks to be fairly straightforward. I'm looking at building one sometime in the near future.

Our field owner has the GP Tcraft and likes it a lot.

I've built a couple of the Great Planes Taylorcrafts. It's my favourite plane, and I hardly ever go to the field without it. I'd definitely recommend that one to anyone.

My first one had a Magnum .30 four stroke, and it flew very well like that. My current one has an Enya .46 four stroke, and it's overpowered. Your Magnum .25 should fly it very well.

do you have any pictures of your taylorcraft?

I built the G.P. T-Craft and powered with the O.S. 26 FS 4 stroke. IMO the engine doesn't have enough power to fly the plane well. Performance is improved somwhat if flown without the struts. The T-Craft IMO needs a minimum of a .30 4 stroke.

You may want to consider the G.P. Slowpoke .15. I built one and modified the wing to accept ailerons. Not a difficult modification and the plane is a good flier.

how hard was to build the slow poke. I read one of the building descriptions and it didn't sound easy.
I like 60 and 60 size airplanes so I might just get rid of this engine...

RE: kit for .25 engine??
 
So many great plans for this size engine, why not try a scratchbuild?
I enjoy this size very much, in addition to the 120 size ones.

RE: kit for .25 engine??
 
scratchbuild might be too complicated. I'm pretty sure I can handle a kit but not schratchuild.
What I like about the .,25 engines is the fuel economy....:)

You are very correct about the economy...I fly this Enya 25 model every week, usuall come home with more fuel than I went flying with :D

Our field owner has a 25FX on his TCraft and it is a great match. The 25 two stroke probably has power output between a 30 and 40 four stroke.

The one comment about an "underpowered" model is using an engine with less power than your 25 two stroke.


I built the G.P. T-Craft and powered with the O.S. 26 FS 4 stroke. IMO the engine doesn't have enough power to fly the plane well.

Yes, I had to put an overflow tank on mine.

Consider the Sig LT25, just stack the parts together and apply glue, I've built two of them using only Hobby-Lobby's SuperPhatic. Flew one with a Saito .30 and the other with an Irvine .25 Diesel. I put a nose gear on the Saito powered one.

paul swany's taco might work, i have the t-craft 20 on the bench, and am putting a TT pro 36 in mine. The tigermoth is available for that engine as plans only. George

RE: kit for .25 engine??
 
I was thinking of the LT 25 however many people were saying that .40 is barely enough for this airplane and that .25 would not fly it well.

Building the Slowpoke .15 is about the same as any other kit. Maybe a little more work considering the wing consists of 3 sections (center, left wing, right wing), and requires a little more time and effort to modify the wing as I did. The modified wing required cutting out additional ribs to maintain a constant cord, new spars and carving wing tips. That said, it's not hard, but is a little time consuming.

I had the same problem as you, in that I had an O.S. 26FS 4 stroke engine and was looking for a suitable plane. The T-Craft is a good airplane, but the .26 was too small. So now the .26 is powering the Slowpoke and is well suited for the plane.

Good luck what ever you choose.

A friend had the LT-25 with a TT .25 GP (plain bearing). It flew great on that engine, and he had a good time flying it in strong winds.

Who says a .40 is "barely enough"? He must like to make epoxy fillets. Either that or he think trainers should be able to hover.

Here's a picture of my current Taylorcraft. This is the one with the Enya .46 four stroke. The prop in the picture is too big. I just put that on it for the picture.

There's a couple pictures in my gallery of my first one with the Magnum .30 four stroke.

I second the taco. I've had one of those, and it was a blast. My 25fx is recently available again, and was thinking of building another one. I dumb-thumbed the last one. But, it was a ton of fun.

He's got a new 25 size out now too. I may try that one.

Scratchbuild, Gordon Whitehead plan, from RCM plan service.

I had a kadet lt 25 and i started with a crappy little 25 (cant remember the name) got rid of it, cause almost everyone in the club tried to get it to run right (constant dead sticks). the 25 had enough power for this model. my instructor suggested that i try a 40 in this model, and it was a perfect match. it flew more like a sport plane with this engine. provided hours of fun, til radio failure did it in.

The Taylorcraft would be perfect for that engine. It should fly with plenty of gusto, but not be ridiculously fast.

I had better pick up one of those Taylorcraft kits before they become extinct.

Now, if it only flies "for real" as well as it does in the Real Flight sim that I have.

I agree that the OS FS-26 would be marginal, but the engine he is going to use is a two-stroke .25 and will be a good deal stronger than even the OS FS-30.

I have the Slow Poke kit that you mentioned and I agree that it too would be a terrific choice.
