Hey knowledgeable people of RC Talk, I have a question, spurred on by the partial success of my scratch build electric tethered car (thread over on the electric section) and pressure from the club to build a ‘real car’ plus if I don’t build something else the missus will find me something really worthwhile but tedious to do, I am looking to build a car based on an Irvine .20 glow engine which I just happen to have lying about.
The plan is to mount the engine sideways in the chassis.
But having taken a good look at the flywheel/clutch/gearing that came on the engine it doesn’t look like it’s going to be viable to use.
The centre of the drive shaft will clash with the flywheel
Added to this the shaft size in the larger driven gear is only 5mm which is too narrow for the fixed rear axle I normally use which is 10mm dia.
So my question is for me to use my Irvine nitro engine I could do with an alternative flywheel/clutch and drive gears.
The engine drive is via a 1/4”-28 UNF thread I think!
Any ideas of what I could use?
The final drive ratio needs to be around 1:2, slightly less might be OK.
I am open to using gears or belt drive to achieve the gearing.
This time I plan to put a bit more effort into the body shell so that it looks a bit like a 1950’s race car. Out right speed is not the main objective, it just has to look like a car, work and make a lot of noise so that I fit in!
