New Space Bug From Parts
dckrsn on Wed Nov 25, 2020 9:29 pm
Hi, I'm building up a later model Space Bug, and I've hit
a snag. To the point, do the later Bugs have a one or
two bypass cylinder? I thought the P-40 cylinder was
the first dual bypass. Dunno. Also, 3(4) piece piston, correct?
I searched, but couldn't come up with any answers.
I've accumulated almost all the parts over a few years,
and almost gave up trying to find a new crank. Matt at
ExModel Engines took care of that.

So I'm hoping to wind up with a
new Space Bug from new old parts parts soon.
Happy Thanksgiving
Pass the gravy please.

Hey Bob, noble project. I don’t know how long they were in production internet says ‘52-‘58. All I can speak to is the one I have it’s a single bypass small thread head with 3 piece piston.
If they did change configuration throughout production just pick the year for the parts you have on hand.
Someone here knows more about this.
Edit: So yeah... I got off my rear and went back out to the shop, spent the whole day out there working on my pickup bed prepping to install new wood, so I didn’t want to go back out. My conscience got the better of me so I thought I should go and look. Basically disregard everything I wrote previously. 302-1 head, dual bypass thin walled cylinder with no markings, normal piston and SPI.
Hope that helps a little. That’s what I get for going off of memory.

Thanks guys. So, looks like it'll have the screened trumpet
intake, later flanged case, numbered thin wall #1 cylinder
and period correct head. I couldn't locate an un-numbered
cylinder, but what the hey.
Ron, thanks for trudging back out to the garage.
Eric, I think about that alot.

Ron's got you pretty much covered for spec.s
You picked the right one, I think the "trumpet" has more character, but both are pretty neat.
Kim flew a pair of these R/C a few years ago. Impressive. He actually fly's these things.
