Hi, My rear firewall was also glued in at an angle, and I don't think this is correct. I went to a bit of trouble and routed the rear firewall to be perpendicular to the fuselage. This needed an...

RE: ESM Dornier DO 335

Jimkron, what I did with the routing is that I glued a piece of 5/8" ply to the firewall, then stood the plan on end in a stairwell here, with my adult son holding it vertical tail up. My wife held a...

RE: ESM Dornier DO 335

"Well first of all, with a centerline thrust aircraft you can never have an assymetric thrust if one engine is out due to fact that the engines are on the same thrust line. "

Well first of all...

RE: ESM Dornier DO 335

I've solved my problem with the bulkhead, Iglued on a piece of 16mm ply and then used a router against the rear of the fuselage to plane it back to be parallel. Now Ihave a surface to bolt my engine...

RE: ESM Dornier DO 335

Part of the ingenuity of the original design by Dornier was that they could use a pair of identical engines, eg not a handed pair like a normal twin would have. This gives opposite rotation as seen...

RE: ESM Dornier DO 335

Hi Guys,

Well, I hope the lack of news from Kahloq means that he is busy flying his Dornier.

I've now acquired most of the bits for mine and have started bolting them on. I'm going to see how...

RE: ESM Dornier DO 335

I know you probably don't want to add more weight...but have you considered telemetry to let you know the in flight battery voltage from on the ground? How easy it is depends on the radio gear you...

RE: ESM Dornier DO 335

Hi Kahloq, Good maiden, albeit with a few teething problems, which I am sure you will be able to overcome. A finer pitch and larger diameter will give a lower top speed, but more important, it will...

RE: ESM Dornier DO 335

OK, so what you are after is really a stud. It kind of frustrates me that I have the means downstairs to make a pair for you in about half an hour, and would happily do so...but Iam probably about a...

RE: ESM Dornier DO 335

Hi Kahloq, That doesn't sound like a very sophisticated solution to me. Iwould probably make an axle myself from a piece of high tensile steel bolt, but then I have a lathe here. One way to get a...

RE: ESM Dornier DO 335

Yes, it should sound good...but I will probably need to put a muffler on the twin because it only comes with two short open pipes. A pair of flexipipes might be enough, and would also get the exhaust...

RE: ESM Dornier DO 335

Looks pretty cool to me...

I've just acquired an ASP 160 twin, it will almost fit inside the front cowling. Just the rocker covers will need a bit of an opening. With the 120 I already have at the...

RE: ESM Dornier DO 335

I think he means the CoG issue that can arise with a heavy engine at the back. Looking back through this thread some guys have had to add quite large quantities of lead to the nose. Then you start to...

RE: ESM Dornier DO 335

It is true that they don't need to match...for any particular combination of motors there will be a prop combination that ensures that both motors are doing their fair share of the work...But the...

RE: ESM Dornier DO 335

As per the original, the two engines should be the same and would therefore run at the same RPM. For that to happen, the rear prop should then have a slightly higher pitch than the front one, since...

RE: ESM Dornier DO 335

Jim,

That looks really nice in the video...seems to fly well. They are an interesting looking plane in the air aren't they.

One thing about the capacitor units, you won't do any harm by adding...

RE: ESM Dornier DO 335

Well, one of our members found a pretty effective way of destroying the outline of a Spitfire, gas powered, I think about 35cc. I wasn't close, but it was either the CoG to far back like the 335 a...

RE: ESM Dornier DO 335

The spinner is actually the right one, they are cut with a reasonable amount of clearance and will still clear if you reverse the prop. At least mine did when I initially put the prop on wrong last...

RE: ESM Dornier DO 335

If a propellor is on backwards it will still push air in the correct direction, but with less efficiency. Look at a normal propellor mounted on the front of the plane as usual. The rounded edge of...

RE: ESM Dornier DO 335

Hi Hellcat,

Ihaven't assembled mine yet, and only have the fixed gear it comes with, so Ihave measured a main gear leg and the wheel. It looks like the wing should be about 320 mm from the ground....

RE: ESM Dornier DO 335

Back on the shaft idea, I am well aware that a shaft 700mm long turning at around 10,000 rpm is not going to be trivial. On the other hand, what man has done man can aspire to, and the Engel guys...

RE: ESM Dornier DO 335

Hi Guys, I see some correspondence way back about the way some ESCs can blow up if the battery leads are too long. I'm not planning to go electric myself, but I am an electrical engineer so maybe a...

RE: ESM Dornier DO 335

Ok, you are making me think a bit. I am thinking in terms of four strokes, two strokes just don't sound right. I have had a good look at the fuselage, there is heaps of room inside just behind the...

RE: ESM Dornier DO 335

Well, the box says 120 in the front and 90 in the back, which is what I had in mind, not just the 120 on its own. Is that not enough? I have an ASP radial but I don't think it would fit in the cowl! ...

Hi Guys, The local shop just discounted all their ESM stuff so I succumbed to the temptation. It is likely to be a while before this one flies since I have a few other projects that ought to come...
