Looking good guys.

That apache Chipmunk always seems to build into a really nice model. Shame the price has gone up so much on the base kit

Phil, it is the 1/4 scale one, I think the 1/3 scale one is a single holer. It is not light; the wing spars for example are spectacular bits of spruce. I fitted split flaps which add to the fun and make landings a doddle. You can just see them extended in this pic.spacewalker cropped.jpg

Sunny days are fake news at this point.

Lovely models though, just don't let my Nieuport see that Pfalz!

Oh dear, maybe mine should belong in a thread ‘Overpowered by Laser’.

Took the P40 up to the field today for its maiden with the 240v up front. This was the first time I’d run the engine but it started after about 10 secs on the electric wrist and sounded superb, better than my 160v. After warming up I ran it to max revs although it faded a bit at the top end and then back to mid revs. Back up to max revs and ‘bang’, the spinner was thrown off followed by a rapid engine kill by me. This is what had happened:

The bulkhead had been ripped out! Looking at it closer it is obvious that the connection between the bulkhead and the fus is very limited and a very poor design. This is a Seagull Models ARTF supposedly suitable for a 35cc gas engine, IMO this is a massive flaw in their construction. Now debating what to do!

Probably gone a bit off topic with my post so sorry for that and will close my entry.

Yikes! that's certainly not as beefy as I would like to see for a model that size. I do wonder if the engine threw the sprinner/prop first and the sudden shock pulled the engine off. That said, its unusual for our engines to throw props and the break seems to be in the direction of the engines thrust. Still a weird one, and obviously the vibration of a single cylinder engine of almost any kind would certainly have done some damage.

It might be worth starting a new thread so that others can see the issue and make modifications to their own model. A phone call to the distributor and even a post on seagull's facebook page might also be a good idea to prevent what could be a nasty accident.

I assume the engine made it through unscathed?

I haven’t had a close look yet Jon, but I don’t think that there’s any damage to the 240v. Sounded beautiful by the way!

As suggested, I’ll start a new thread about this.

My 1/4 scale SE5a from the Dennis Bryant drawings.

Went overboard with detailing somewhat which resulted in a porky 24lbs but the Laser 180 pulls it around adequately.

Either the ground is very soft and it's overweight (as you say) or she's sitting in a rut!

Never mind, it's absolutely gorgeous.

Paul, your Pfalz is lovely. Superb build.

I have Dennis Bryants plans for the 1/6 scale DXII and I am retiring this year so.....

Seagull Dual Ace with twin Laser 70's,

Major result for me, comes in just under weight and no added lead ballast (RX batteries are behind the canopy).

Taxi tests complete, minor work on throttle linkage and then it will be maiden time!
