Default Installing RC in an old Tandy Buggy - help needed!

Hi Guys

I have recently purchased a used, old Tandy Buggy EP 1:10 called Fox 7, which I believe was rather a toy then a serious model. I am new to RC cars (albeit I've been driving nitro Kyosho PureTen) and I want to install a proper RC system into it.

As a first thing, I've purchased transmitter MEGATECH AM T-2PHKA Robbe Futaba 1-F2223 40MHz and now I need to buy receiver, regulator and servo. However, I have no clue what to buy for such a car and what are technical specs for such equipent:

- Which servo - what torque, speed etc ? I have got an offer for the Hitec Ht-422 servos, are they any good?
- Receiver - I know that it should be 2 channel, but : any brand would do with this radio? How will I deal with a channels (crystals)?
- Speed regulator - again, technical specifications needed for such a model

A last question: how can I figure out the voltage of the motor if there is no technical spec on it? Is there any simple technique?

I would appreciate any reccomended links to the articles, which would explain me those basics, or definitely your advice written here will be as well appreciated.

Just fyi, I live in Belgium thus the equipment which you would reccomend shold be available in continental Europe.

Thanks a lot

Default RE: Installing RC in an old Tandy Buggy - help needed!

The car was likely originally 7.2 volts so i would go with that. Any 1/10 scale ESC (speed regulator) will easily handle it, look for something that will do around 100+ amps to be on the safe side. You probably should replace the motor anyhow if the buggy has seen some use.... a 27 turn closed can motor is probably all the drivetrain will handle...

The hs 422 servo will do, but its definitely not a powerhosue... its about what you would expect in a RTR truck... Buts its a good bet is miles better than the "servo" the car originally had. I like my servos to have 80+oz-inches of torque and less than .20 transit speed, higher torque and faster speed is always better...

for the reciver, a 2 channel futaba or hitec RX should work, make sure its 40 Mhz, and get it on whatever channel the TX is on.
