Could it be a faulty electronic ignition unit?

I had an Aurora with GF fuselage and foam wings. I fitted a tow line release to the nose and we did a bit of aero towing . It flew fine as a glider.

How about a pair of large bent-nose circlip pliers. Insert the tips in two front housing bolt holes (but not too deeply so as to engage in the crankcase holes) and rotate the front housing. That should break the seal so you can pull the housing off. Just an idea. I've not got a laser 200 in-line so I've not tried it!

Thanks Jonathan

Looking for a good Saito 45s. Must be the latest version with modified crankcase, locking prop nuts and later cast ali muffler. Should be stamped with the letter P ( or later letter Q, R etc) on top of the right mounting lug. I'm not interested in earlier versions. Thanks for looking.

Time to keep the garden beautiful and well-stocked with vegetables as well as build top-notch models! Impressive work Nick.

Yes, a great job that really does look the part. It will add enormously to the scale look of the front of your Pup. Impressive work.

David Boddington designed very many models, He did a 1/5th scale plan for the Sopwith Pup. Maybe the new model you have is 1/5 rather than 1/4 scale?

Nice work Chris.

Model shops (with websites) here in France list 10mm Square balsa so it is available. Maybe mail order?

For scale models with a sheet (ali or ply) covered wing then an "open" structure would look very wrong.

Another vote for Toolstation CA. Cheap, works well and doesn't seem to go hard in the bottle like some others do.

Still using my JR 10X tx with a 2.4 module. Utterly reluable and I wouldn't think of parting with it.

Well I'm not going to accept all cookies just to view videos. So these new "updates" have just made the forum much less useful for me and much more frustrating. Hopefully the tech guys can sort this issue before users stop using the forum!

There is still the issue of not being able to watch videos without accepting all the cookies. Can the techies sort that out too please.

I have a saito 125 in a Seagull Chipmunk. It flys beautifully its not a warbird but was used by the military. No retracts but it does have flaps and landing lights

Looking for a nice Laser 200v, 180 single, or perhaps a 300v WHY?

Selling: OS FT160 gemini twin. Perfect working order. With latest twin-needle carburetter. Also twin flexible exhaust extensions and 2 x OS mufflers. Comes with instructions booklet. £425 Saito FA-115 four-stroke. Excellent condition. Original box plus manual, tools, muffler and Saito glowplug. £200

OK. Thanks

Obviously Jon is now on holiday from work. At least I hope he is. Just wondering if he can give any idea about when 200V or 300V or FT200 engines will next be available to purchase

The full size is all painted metal so plastic film won't look too out of place and will most likely be lighted than glass-fibre and paint finishing. But not necessarily so of course. Some modellers on here are super proficient at getting a great finish with minimal weight gain. The glassfibre cowling and aluminium undercarriage at least will need painting though. Other areas hard to film cover would be the ailerons, flaps elevators and rudder that all feature a triangular "corrugated" surface. Quite tricky to film over.

Deleted my post. It Christmas!

I found this video of a Marutaka Bird Dog with an OS FS120. Flies nicely and seems about the right power to me. Bird Dog video

Mark, I've just got the Bird Dog plan out to look at. From the sketch drawing of the fuselage you can see that there is the fuselage side plus the doubler F25 to glue to. In addition there is the block F36 at the rear plus 2 formers F14 and F15 plus the front of the tailplane will glue to F13. That doesn't seem bad to me. But it would be easy to add some crossgrain balsa sheet infill as has already been suggested by John. The tailplane has reinforcing spars built in. The base of the vertical fin will need to be sanded to a snug fit with the top surface of the tailplane. But there are also the 2 substantial fillets F38 that will reinforce the joint either side. Well-fitting parts properly epoxied into place make an amazingly strong joint. I don't think you need to worry about the structural integrity.

I also have the Marutaka Bird Dog kit waiting it's turn. The plan shows the servos in two different locations depending on the engine used. The plan shows an OS Gemini FS twin which is heavy. The plan shows the rudder and elevator servos way back in the fuselage because of this. Servos will need to mount much further forward if a single cylinder engine is used to get the CG correct.
