RC Toy Car Ducted Fan Conversion FAIL


kurt WAPOW asked "hey grandad can you make a ducted fan car?? just keep the steering on the car" so taking a cheap RC toy car I tried using the motor from the car and adding the impeller from a hairdryer. I could not get enough thrust, I tried various options but I think the simplest answer would be a proper hobby grade RC EDF then we would have plenty, but we would also need better batteries and then probably better RC gear so really a proper hobby grade RC car. I tried using a 9v battery in place of the 3 AA batteries which would normally give 4.5v and it did improve the thrust but not enough and the receiver got warm although it hasn't burnt out yet. After filming this episode I tried shortening the duct and that seemed to help a little but there still wasn't anything like enough thrust for what we need here.

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
