e-Mikado Logo 400 500 600 > A GENERAL QUESTION ABOUT ELECTRIC vs. NITRO

I currently have the Logo 20, which, according to most, will perform similarly to a .50-class nitro heli.

I'm guessing that motors and batteries will improve in leaps and bounds, and provide vastly more power and even flight time than their nitro counterparts. I'm sure that in 5 years, Plettenberg or Hacker or Kontronik will produce a motor of the same size and weight as the current HP300/25/A3 that puts out more power than a .90 glow engine while still mounting nicely into the Logo 20, right? And some battery manufacturer will produce some kind of battery that offers a half hour of 3D flight time for LESS weight.


So, five years down the road, what's to prevent me from using the newest motor and the newest battery pack to make it perform better than even the best .90-class nitro heli? I mean, can't you take virtually any QUALITY electric heli (like the Logo 20, 24, and Joker), throw in the fanciest motor and batteries and improve its performance? What are the limits? The strength of the blade holders??? Durability of the gear teeth???

For nitro helis, the limit is obvious: the heli is designed around an engine of a given displacement. If a heli uses a .60-sized engine, there's no way to make it perform like a .90 within our lifetimes. Engines aren't improving that fast. With electric motors, however, size isn't an issue. As I mentioned above, 5 years down the road, you'll probably be able to get a motor of the same size that produces twice the power.

Even though electric power systems have improved a lot and will continue to improve, don't forget they still have to comply with the laws of physics!

The motor isn't really the issue. Brushless motors cannot improve in leaps and bounds because they are already 80%+ efficient. They can only be improved incrementally.

Really, it always comes down almost completely to the batteries. The future depends on better batteries. Now we've jumped to LiPo and seen an increase in flight time sufficient to satisfy almost anyone. LiPo is not capable of huge increases in capacity over what we have now, but current capability, reliability, charging safety and hopefully charge time, will improve significantly in the short term.

Two improvements needed:

1. Motors that can handle more voltage and amps while retaining its weight and size (and stay running cool).

2. Batteries which can produce more volts and capacity while retaining its weight and size (and stay drawing cool).

And don't forget ESC's that can handle the high current and stay cool and not burn out!

I'm not really an R/C pilot, I stayed in a Holiday Inn Express last night!
