Solving the radio problem
Posted: Wed 3. Jan 2018 17:20
A happy new year to Keld and all. Having finished my latest hobby project, I thought I would have a look at the Magracing scene again. Judging from the many people viewing my video channel, there is still plenty of interest out there.
I know that Martin is working hard on the radio problem but it seems to me that, if a temporary solution, probably in the form of
using 2.4gh proprietary radio could be found, then at least some system could be offered to new enthusiasts.
I have looked at this before but, Googling the radio scene now, it would seem that there have perhaps been some improvements.
Certainly the prices are low. I have not studied all the makes but the Flysky FS-GT2b, which I have ordered, will cost around 19/20 £/euro with receiver and Li battery. I believe that this has recently been changed from 6v dry batteries to 4.2v Li so this would be a good move. The rx also operated on 4.2v. The rx is not small but perhaps, with the case removed and wires hard wired, it could be used. Certainly would be ok for 1/24 scale.
There is a mass of gear available now, particularly for lightweight indoor model aircraft, drones, etc., The problem is finding
small receivers, servos, speed controllers, etc. which are compatible with each other and operate on the correct 4.2 voltage.
Also most mini speed controllers are for brushless motors so not suitable.
Servos are very small and low cost and I am looking at these for steering in lieu of a coil. Speed control is difficult. I may even try a 2/3 speed resistor board on a servo. We used these for 20 years on our r/c cars.
My knowledge of electronics/radio is very basic so I will be looking for advice when I get further into it.
