1/4 Scale SE5a ( The Old Dutch )

Ian M · May 3, 2011

70 inches that's almost six foot! That's almost as tall as I was!?!?!?!

I was talking to my friend at work and the "free" limit over here is 7kg take off weight. So either I will have to find a little/smaller aircraft, or join a local club. All aircraft over 7kg have to be registered and insured by law!!! Oh and you need a RC flight licence (?) as well. I might just stick to building one.

Ian, though this model is the size it is, it will be well under the 7Kilo limit, i will confirm the weight once built.

I promised you some pics of the engine bay mountings so here they are.

This first pic shows the rails i fitted that support the paxalin mounting plate. This was a disaster, i screwed down the plate to the rails and the rails split.

Not good me thought. A little over engineering required here, i wont take the risk of it coming lose considering the engine torque and stress to the bearers. i decided to use a wider piece of timber a better adhesive than epoxy resin and drill through the timber to take bolts instead of screws, i also pushed dowels through the sides for extra support.

As i said, i settled on Paxalin for the engine plate and not alli as i was going to use. The Paxalin is lighter and just as strong.

Having worked this material to accomodate the engine i added extra strips of Paxalin at all of the fixing points for even better strength.

Once the engine had been positioned it was discovered that the exhaust fell foul of the rear bulkhead and i had to be cut out to accept the silencer. The silencer now sits in the fuel tank compartment, not i deal but its not a problem as a short heat resisting tube will be fitted so that the exhaust exits the bottom of the fuse.

Now its time to scale out the engine bay and fit the radiator.

This is going to be a brilliant model and a fitting tribute. Very well done so far and I hope the rest of the build goes as well as the progress so far.

Excellent

Looking better every day!

I cant recall if I have given you this link before but I think you might find it interesting. You have probably seen it but if not take a look at this

It might have some thing you can use.

Andy the engine bay looks great, ca'nt wait to see the exhaust replumb .

Sky Raider · May 10, 2011

Thanks Trey, not quite sure how im going to do this as yet. As the exhaust wont be seen i may just cheat and use a piece of special silicon tube to just extend it through the botton grille. I may also make a manufold for two ports at the bottom. Stay tuned for the outcome lol.

Cheers

Ian M · May 10, 2011

'Ang on Andy. Could you not run the exhaust out to the "real exhaust" Or would it cause to much back pressure in the engine?

The way I see it is the SE5 had that nice exhaust down the side of the fuselage coming out of the engine bay. Make the pipe out of ally tube and run the silicon hose from the motor own through that......

Juat an idea. (bonus, you will get exhaust staining where it should be too)

Ian M

Sky Raider · May 10, 2011

Hi Ian, that would be an ideal situation but back pressure and engine overheating along with fuel spreading over the plane. Those nice looking exhausts will be constructed but the real exhaust will be routed out of the bottom where it cant be seen and spray less fuel along the fuse.

Cheers

Absolutely amazing Andy! I don't know anything about this kind of aircraft but I'm thoroughly enjoying watching you build it.Keep up the good work,I know you will.

Cheers

Steve

Sky Raider · May 11, 2011

Thanks Steve. Its a good project, i will post some history soon on this aircraft. What i can tell you now is she was a WW1 Bi-Plane and was very effective.

Thanks again

Andy

Ian M · May 11, 2011

I see you've already found a use for that link I posted the other day!

Motor room looking fine now, I think the dash will be great when you are done doing your magic!

Ian M

Sky Raider · May 12, 2011

Thanks Ian. It has been a fantastic help.

A little more progress today on the dash. I looked through my stash of bits and evergreen and this is what i came up with.
