The resurrection of the frankenplane

An old engine that has had a lot of life I started cleaning Then I notice some detail on the modification made Very wide air intake We can see an alteration on the crankchaft To allow a small leak allowing to take air more quickly a fraction before the opening of the window

By deduction I believe that it is the cylinder of the OS the other cylinder is in a box somewhere What leads me to believe is the OS cylinder is that this cylinder followed the head of the engine when removing it lets Say I expected more resistance from this part to remove

Difficult to see but the two ports on the cylinder are modified I have difficulty remembering but with a thorough inspection we can see the small details that make it perform well

After finding the other cylinder I was able to make some comparison and this one is larger With larger windows in the cylinder Different angles to direct the air more efficiently This is what gives all its character to this monster of revolution

I just have to install the carburetor Which is installed on other OS .32 boat engine
I believe it will be able to function for a few more flights before having to re-inspect it Some parts are very good, other less I will adjust it at the next dismantling by this time I will have to find other engine parts

Just keep at it David. It's a worthy project and I really like that plane.

Today I did a little cleaning in the storage room. I watched the repairs to be made On the plane the inner reinforcement of the wing Seems way too small to me . I am going to modify them I wonder how maybe i have an aluminum tube lying around Or  wood bigger stick longer  I will reinforce the landing gear

I made a lot of room



But I still have to place several things in the new glass cabinet that my aunt gave me

I am making progress I have strengthened Fixing the landing gear It was all twisted


I think it's the wings that will be more complex to repair the more I have to lengthen the stick insideThe wing curves with the excess weight du To speed Abrupt looping maneuver I believe I should use an unmodified engine I believe it would be safer for the plane

I found bigger wheel This should help For better rolling on grass

I also found wheel pants Who could be installed I also found two enya .35 motor heads It is indeed a cylinder of an Os engine Install on Frankenstein engine it has the os head the piston too So he is half OS half enya. its a enya crankchaft crankcase wit os cylinder piston conecting rod But with the piston pin of the enya I have to find a piston pin with two teflon tips Because the copper end caps Leave a mark in the cylinder I wonder if it's normal that she is free to move sideways inside piston No clip nothing to hold it in place I was able to take it out by tilting it sideways

The comparison of the two enya head one with a high compression rate. I think I will use it on one of the engines that rsv1cox (Bob) send me Who should arrive soon I can't wait to receive them

Well it was quick someone knocked on my door ho the delivery man Sudden excitement  
engine is in very good condition I will install one as is Directly on the plane I think
One of the two will become a donor The three twins with the little brother

I'm glad that they made it David.

Bob

I am currently working on two the .15 the .35 which had a carburetor The .35 needs a little love Resurfacing the tapered shoulder on the crank for its drive plate Polishing of bearings surfaces The motor head is a medium A little better than the base one


You can almost see the small damage on the conical part of the crankchaft On the .15 I have to drill One hole and make a channel on the other side To instal a little os pipe I believe I have another carburetor which could improve the air fuel mixture Unlock him some more turn

.35 After a deep cleaning I tried to remove the cylinder sleeve from the crankcase But without success I didn't want to break anything

Three different heads I will use the highest one

This engine has extreme good compression now Impossible to turn by hand without a propeller Without the glow plug I can turn very well I feel the compression of the crankcase despite a small leak but I will all repair it is not a big thing just a crack in gasket i like To use permatex motoseal After having cleaned the crankcase well I apply a thin layer and then install the old gasket in places I close with the other side wit oil so that the gasket does not stick to the other parts just its casse After an evening to dry tight This morning I equalize the surfaces well, there were still small leaks now that it is equal I will put a thin layer and then close with the oil on the other side So that it is not impossible to dismantle again without braking the gasket It should seal well


The beautiful little .15 is ready for use This little engine is already very promising I have a lot of fun modifying this little beast

I decided to use the motor that I cleaned and that I installed a pits silencer It adds weight at the front but better centered Before the pipe came out on the side Unbalancing the plane added too much weight on the same side plus look bad With the big pipe sticking out on the side I have another nose but new I will want to wait after the first flight I believe I can modify the one that is installed Without adding too much weight

I think I can fix this big crack

For now the nose is centered with a piece of cardboard While waiting to solidify it Much remains to be done before i have a viable plane to fly Again

It's coming along little at a time , at least you have the powerplant figured out and ready

I did not test the engine but I know it is very good For now I am preparing a fuel tank I have some problem with the piping I wonder if I connect two air inlet to the silencers One tube points to the top of the tank, the other to the bottom But the two connected in one Y Connector pressured out To tank
But I wonder if one direct line wouldn't be better ?? Even if it is submerged when the plane is inverted My only goal is to have a constant flow of fuel Who follows the engine speed Because it is a 3d plane it is an important point not to be neglected I really need the engine power to land

Progress on repair modification of the nose cowl It's much better now I haven't finished everything I want to add a bit of shine [/url]

Paint apply quickly I did not take the time to repair everything perfectly litle bit of Sanding here and there With a layer of glitter in the clear It should look good But I'll have to wait until tomorrow to do it This is what he looks like now

It looks like you almost have it ready.

The project is going well. Slow progress but I do little things here and there


Now with the clear and glitter

I have modified the needle valve  I just wanted to make a notch for a flat screwdriver Then I said to myself that it would be better to have a stick with L clevis lever More convenient in this way To adjust the mix No tool needed I drilled a hole for the exhaust gases For one of the silencer outputs For the other exit a tube joins the exit of the cowl


It's not perfectly straight but should be correct Good for test flight wit this new engine setup
