Motorized model Revell engine

The model is a Revel Visible V8.

I designed and built the motorized system to automatically spin the model. I used a 6v battery for power and a 25 ohm potentiometer to step down the voltage and control the motor speed. I found a R/C drive belt i at a hobby store to drive the crank. I can adjust the tension by moving the box on it's adjustable mounts.

future plans are to add LEDs to illuminate the cylinders in their firing order, as well as the motor box

i cant get the push rods to work right can u help me?

[stanglvr]

are they lining up correctly with the camshaft as well as the rockers? my biggest issue with the model was sanding all the part so they would fit correctly and line up as they should.

@supermario513 the hardest thing about making a model like this is getting the push rods to work with the camshaft and also to set the timing right

[pleasecho2]

I solved the camshaft and ignition timing issue for good by replacing the bevel gears with special ordered nylon ones and drilling the camshaft for a 4-10 threaded rod to stiffen it at the rear. Then I tapped the front of the camshaft and bolted it to the front of the engine and added a steel shaft to the distributor. Pics and video by request. I also donated this info to stunnuts@aol.com who sells VV8 kits, parts and mods.

put oil in the crank case and see if it lubes everything! Then it should run smooth :)

hey mate im thinking of buying one of these because i want to learn about engines does it teach you alot about how they work in a real car and does it come with that thing that makes it run on its own or did you make that?

[djvortek1]

where did you got that engine to power the v8

[silicon212]

@crazytacostudios Due to the amount of "shrouding" of the valves, it's easy for them to get stuck. Intakes are really bad on this, but usually can be unstuck with a pair of needlenose.

[silicon212]

@superfunnyman123 Absolutely not. There is a LOT of clearance in the parts of this engine model - there's about .5-1mm clearance between the pistons and the cylinder walls. Even more in the crankshaft bearings.

@stanglvr did this come with instructions

Can you use/run it if you put it in a model car type of thing?
