Yep. Save the Heinkel has very good brakes. I have never had insufficient brakes to stop, I have had insufficient grip, which is entirely another matter. Cannot say that for my Nobs. But then you drive to cars performance and the Nobs I had were not that nimble either. The Heinkel is, done correctly, as it has a brilliantly simple steering rack and good steering (let down by the suspension/damping). So the speed is governed by the suspension, not brakes or power available, when its all working well. In addition the gearbox is good enough to use a downchange to aid braking/handling by shifting the centre of gravity back as you accelerate out of the corner earlier than not changing down. Here you will find many who disagree as they never had a gear change that was set up correctly nor were prepared to rev the engine as it is designed to be, prefering to plod. Get it wrong and you can easily tip over so its trusting your abbilities as mechanic and driver. Such a Heinkel would be nipping at the Messerschmitts heels and leaving the Isettas looking for another gear. I know, we proved it on several Story trips and runs through the Harz Mountains. This is not to say an Isetta cannot be driven with spirit but ultimately its great weight prevents it keeping up despite have 50% more volume in the engine. Cruelly shown on hills were the Heinkel is probably the best climber per cc out of the whole microcar group.
