Probably could work, hadn't thought of it. Regenerative braking is usually such a small affect that it is proably more work than it is worth.

I just thought of something, we can use the slave motor to do the braking using a standard brushed ESC and some diodes!!

I have also made this idea work for a lehner basic 4200 and a novak 10.5 running on the old SS5800 controller. I haven't road tested it yet, but it works well on the bench. I did cheat and use an...

To get the same performance out of a lower Kv motor you need to have higher voltage. You are correct when you say that the higher turn motor has more resistance. So.... at a given voltage you can't...

May not help if you saw it with the plastic chassis. You can still try it though. Mount it on some foam padding or something that can absorb mechanical vibrations. Also, try to route the antenna...

did you try using a regular receiver pack?? or moving the antenna and receiver off of the metal chassis? These are free things to try before replacing parts that may not be the problem.

Statement #6

Losses are the current squared times the resistance. So... reducing the current draw by a factor of two lets say, reduces resistive losses by a factor of 4! So what you have said in...

FM and AM are in the same carrier band, both are susceptable (sp?) to mechanical vibrations. This is supposed to be the advantage of the newer 2.4GHz systems.

As for the problem. does you...

Has anyone seen the Fine Design way of doing this. I know they sell them with the clutch bell already attached. Maybe they did a press on thing too.

Unfortunately, there is no appropriate pinion. I think I can make it work with an airplane prop adapter. A little bit ugly, but it has worked in the past.

Clutch Bell Adapter

Does anyone make an adapter to use nitro clutch bells on the electric motors? I would just buy a mod1 pinion except this is a two speed clutch bell that I have for an old pirate 10.

Thanks!

Do you have the stock rotor in the novak motor? I put my feigao rotor in my ss5800 can and it worked much better. I would venture a guess that the novak sintered rotor upgrade will help too. I run...
