I would but I don't think the hull could handle it. Its also a little to much money. I have way too much money in that hammer. I love it.

Hey ron, is that engine I showed you anymore powerful then the O.S. .21?

Ron Olson

My Feedback: (1)

I don't know, compare the numbers on Tower for the OS and Aeromarine on the OPS.

ejp67

My Feedback: (5)

Well aeromarine doesn't have any specs. Now what. Has anyone seen one run or know anything about them. Are they pretty fast?

ejp67

My Feedback: (5)

Ron, can you explain the layout of your boat. Where is the fuel tank? Where should I put mine. What should I do about push rod seals? Should I use the flexshaft type push rods? Explain how mine should be layed out PLEASE!!!!!!!!

Ron Olson

My Feedback: (1)

It goes up under the front deck. For carb linkage, use a piece of rod that has a 2-56 thread. for the rudder, use a 4-40 threaded rod for that.
All I can show you is my boats setup. go here, I just posted some tonight: http://gallery.intlwaters.com/index.php?cat=10008

Did you build or buy your boat? Will my boat have as much room as yours? (I saw yours on th boat stand thread) Where is your pressure line?

Macleod

Hi ejp67, We should start a 'Wild Thing' Construction thread....

As I am currently building the 'Wild Thing' also...

As for the pressure fitting, put it in the tuned pipe at its widest point.[8D]

My wild thing will be 30 in by 9 1/4 width

There is different places for the fuel tank. its place depends on the balancing both port and starboard, some have one tank and hopper in the middle and others have it on one side with hopper in the middle.

I just answered this elsewhere. The pressure line is hidden in the pictures. The pressure lfitting is facing down under the pipe and runs the route.

ejp67

My Feedback: (5)

Well, as soon as I get my plans and wood the construction will start.

Hey, ron I was looking at your pics. The yellow boat, the rudder isn't very far back from the transom. Can I use a regular rudder the the mm18 rudder?

Ron Olson

My Feedback: (1)

You might be able to use their combo. You might have to put some spacers between the transom and strut though.

Macleod

Hi Ron, Do you have any photos or can you explain the spruce strips that go down the side of the wild thing after the hull bottoms and before the side wall hull pieces???? They from the spray rail, I guess???[&:]

"Cut and glue 1/4x1/8-inch spruce strips along the hull's outer edges. Let them overhang the bottom of the hull so that they can be sanded later to form a good fillet between the hulls' bottom and sides." As quoted in the instructions....Just unsure of how its to look...

Thanks

ejp67

My Feedback: (5)

Good point. I have read and read that and don't understand. Ron all I want to do is use the rudder for .18 to what ever they say. The brass colored one.

Ron Olson

My Feedback: (1)

nope.

Ron Olson

My Feedback: (1)

That will work.
I'm going to bed now, it's late here.

ejp67

My Feedback: (5)

yep. Well when I get my plans i will see if I can figure it out. Do I really need to use spruce. My dads friend said I can use oak.

ejp67

My Feedback: (5)

Hey, it looks like in the pics that the hull sides are already in place. They look more like they are where the sides and top are jointed.

ejp67

My Feedback: (5)

Mac, what is the hull bottom made of. What is the 1/32 ply for?

Macleod

There is two pieces to the hull, The two bottom pieces and then the sides. Ive got the plans here in front of me..... But it hard to understand some parts but we can help each other with the construction......

ejp67

My Feedback: (5)

If you look at the pics on rcbm I am almost sure that the hull sides are in place. You have the balsa bulkhead and then the little up and down piece where the hull side is glued to. Look at the pic, the hull side is already in place[]

Macleod

Do you want me to photograph my plans as an overview to show you the side pieces, but not copy and send you the pic???

CMB RS35

Ejp,

The OPS .21 engines put out around 1.8hp@30500 rpm. They have reasonably good performance compared to a lot of sport engines but are not competitive against the likes of CMB or NovaRossi etc.
To be honest I was always a little disappointed with the performance of OPS engines ranging from the 21 to the Speed90. They were smooth but lacked any type of sparkle. We used to get rid of the standard carbs and change them to those made by OS
