Jerobee Corvette

Very nice!! Do you know who made that model?

Hi Crank, it's a 70's model made by Jerobee Idustries, owned by Jomac.





Lieven

Pretty cool model, don't see many. They sure did a lot of work on the tank.

Nice I Like ,What is that rubber band looking thing at the gear system in pic 3 for ?? Does that put it in/out of gear when you flip the switch ? Looks like a lot of fun coming up you are going to run it Lieven ? Eric

Glad you like it guys. Eric, That's a brake. When the engine goes to idle, the clutch weights are disconnected from the clutch housing and the throttle servo pulls on this band which slows down the car. It's common on RC cars. It will be run but I have to check the engine, do a minimum of cleaning and fix the radio gear.

Lieven

Ok Thanks Lieven , I am not to savey on rc cars and have had and have one of those brass ? wheels for the brake and was wondering what it was for but I have seen them on boats for starting I guess . Hope you shoot us a video when you do decide to run that Corvette . Eric

I'll have to keep an eye out for something like that, Way COOL!!!

It's the Jerobee Corvette with the external plastic tank and perforated Silver Bee tank or should I say heat sink? It came with servos and servo saver as well.





So 1 more project to add to the list, but if we wouldn't have projects, we would stop dreaming and life will become very boring.

Lieven

Lieven: please don't hold this against me, but I almost bid on this item, or one exactly like in on the U.S. ebay. I didn't see the Corvette body, so it may have been a different auction. I have always wanted a Corvette model car, but I settled recently for a 1/24 scale 1957 model.



I may make an RC car out of it. I need to see the car first.

edited at 10:49P.M. 9-22-15 - to add a picture of a proposed RC version of my 1957 Corvette.


one variation of proposed RC version of 1957 Corvette Metal Cast Model
Note helicopter motor, small 3amp. ESC to it's right, lack of gear on motor.
Now all I need is the proper gear for motor and for wheel axle and a way to get it all in there without cutting anything. I can do it by cutting some of the plastic away, but the goal is no cutting.

happydad   high 90's tomorrow

HD, I didn't buy the car on EBay but over here locally. I'm looking forward to seeing that RC Corvette!!

Duke,  35.000 Jerobees were made. 30.000 with Bee engines of which about 5.000 with the external tank as mine is. Then about 3.500 with the TD engine. The remaining 1.500 were sold as spare parts. I think you 'll have plenty of chance to find one. The TD engined Jerobee is the top of the line though but prices are accordingly as you might guess.

Lieven

well I was looking and found this I know its not the same but cool      http://www.ebay.com/itm/Cox-1-20-Scale-Buick-Corvette-Sting-Ray-Gas-Powered-Thimble-Drome-race-track/281798035756?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003132420%26meid%3D4dc4173c34cb4e4fb6beee041a613b66%26pid%3D100005%26rk%3D3%26rkt%3D6%26sd%3D361377444801

Thanks Man! Now I must search the web.

There is a Cox powered Buick somewhere on eBay. I think it is NIB and they want $399.00.  Ouch

There are other Cox powered cars like the VW dune buggy, Van, etc. that are less than $100.00

Happydad.

Just realized, Jerobee and JoMac were connected, a friend of mine was part owner. Don has showed me so many awards and what not from his race days. Don is also a great control line combat guy. I'll have to email him today to talk about these cars.

Duke, Is that Don as in Don McKay?

http://jerobee.blogspot.fr/

Yes, the one and only. He's a great guy and I'm chatting with his as we speak via email. He says he still has the TD Jerobee that won the last NAT fuel 1/12 scale oval.

That's a badass Vette! A car is one RC thing I Can operate. I've been known to drive the crap out of 'em. In fact I have about a 10 pound bag of RC car parts,a few electric motors included. Once I used one of the battery packs to soup up a sluggish Radio-Shack Big Wheel pickup truck. That thing would flat haul ass. I thought it was fun to roll it by over steering at high speed. I gave away all of the unpainted body shells. I drove it until it was completely worn down and out.

I bet that Vette won't flip over like the Big Wheel would. Let us know when you take it for a joy ride.
Rusty

That's great Duke! People like Don have plenty of information to share and a lot of history too. I hope he'll visite us on the forum.

Thanks Rusty, were your cars all battery powered? and off road I suppose. What scale were your cars?

Lieven, they were my friend's cars except for the truck I mentioned, which was mine, which was just a toy. He gave my son a garbage bag full of parts for his high school robotics club. The cars were maybe 30 or 50 cm long... it's been 20 years or so, and I don't recall exactly. They were all electric. He raced them at a club in Raleigh, NC. I'll look at one of the motors and see what kind of power they used. The battery pack was wider than my truck and I duct taped it under the chassis.

Duke: Are you watching the sandblaster thread? Someone started a thread showing the RC versions of the sandblaster, VW bug, VW buggy, Jeep, and others and I have been posting ebay ads for inexpensive, relative, RC and not Cox cars in that thread. check it out if you aren't already.

I was trying to post this picture of my proposed drive train, but the pic got stuck in never, never land for and hour. I took the pic with my iPad and sent it to myself so I could do things easier with my PC. I sent the pic at 10:00p.m. PST roughly and it just came to my email at 11:12p.m. PST. If I would have known it would take so long I would have used my camera, transfered the pics to the PC via an adapter for my camera memory card and been finished by 10:30p.m.  whatever
 anyway here is my second proposed drive train with the same helicopter motor, same ESC, but different wheels and axle. I couldn't get the wheels off the Corvette axle, someone had glued them on. Don't the wide blue slicks look cool on the 'vette. I think the blue wheels are too small in diameter, but it gave me a better perspective on the fitting of the motor to the axle and how it would fit into the body cavity. I used to build slot cars during the late 1960's in Japan when I was there in the USAF.


the fit looks a little better. I just need to find the right spur gear for the axle. I need to measure a couple of the spur gears for the right diameter of the Corvette, looks like 3/4 or .75 inch.

      p.s. that is not a spur gear on the axle, but it is the last Cox slot car gear I have.

This is the 2nd revision of proposed drive train for the RC version of my Corvette. It uses a Helicopter tail rotor motor and gear for driving the rear axle, and a small ESC that can handle up to 3 amps. I figure everything should fit under the trunk except maybe the main battery. I was thinking of using a 350 mAhr battery along with a 2.4Ghz 4 channel receiver.


proposal #2 using helicopter tail rotor motor and gear to drive rear axle.

Coming together well, HD!!! Any idea's about steering and front axle?

Way Cool Vette Lieven! That throttle linkage must have been a challenge to design. The bend-angles on the pushrod.. it's length.. the standoff/guide that transfers the motion 90 degrees to engage the throttle-clip.. Even the servo-wheel's range of motion and pushrod position had to be very precise. Great photos BTW.. good to have as a guide for maintenance/reassembly.



This throttle-clip ear looks like it had to be bent/tweaked so as not to bind.



You had mentioned pulling the engine to clean/inspect? Let us know if it has the larger .082" (2.08mm) air-intake/venturi. I'm wondering if the engine components were along the lines of Black Widow, as far as performance. Since Jerobee also made a Tee Dee version.. I'm very curious about the cylinders/porting used on both engines. Do the ground cylinders have sub-port induction? I know that "mufflers" augment the benefits of SPI.. but does an exhaust throttle? The cylinder would still be sucking in fresh air.. just less of it when the throttle closes. I just noticed the brass cylinder-shim.. maybe that's in place to eliminate SPI for use of the exhaust throttle?

Congratulations! It's a mechanical marvel.. and I hope you have a lot of fun with it! If it were mine.. I'd build a dyno for tuning it!
