I'm pretty new to Heli's I just got an HB CP2 and I'm learning to hover ok, but I've burnt up about 4 Main motors is less than 20-10 Min. Flights, So I'd like to Upgrade to brushless but I dont want to spend too much mula as I also want to buy a Nitro or Gas Heli. Do I have to have an ESC? What size of Motor can I buy? Where should I buy it at? Also the HB CP2 has a 4 in 1 Reciever/Gyro, would I have to replace all my Electronics? Please Help

Well,,, first thing,,, I own two Honey Bee cp2 ,,, and One Blade cp,,
If you are burning up that many main motors ,,, something is very wrong with your setup!!! And I can't tell you what it is very easily.
Most main motor will last,,, say 7hr, of flight time!!! At $6.00 each is very cheap!!One thing I do is hover for 5 minutes and let motor's cool off for 5 minutes,, you get the idea...

One thing to check,,, are you running to heavy of training gear? Make sure you use the ones made for the Blade cp or honey Bee cp2.
Next, when just hovering,, don't use body or cabin on your helicopter at all,,, The down wash from main blades will help cool motors.. Next, put on heat-sinks on main and tail motors.Next, make sure that main motor pinion gear,,, is not to tight on big main axle gear!! You should be able to run a piece of heavy paper between them where they mesh. Next check your pitch!!! If you are running to much angle or pitch on main blades you WILL BURN UP YOUR MOTORS!! One way to check this,,your helicopter should just start to hover off the ground at about,,,, 3/4 throttle.. If it at half throttle you have to much pitch!!! I would do a search on adjusting pitch ,,,same pitch setup on Blade cp will work on Honey Bee cp2...
And last,, it would cost about $200.00 more to go brush-less main and tail motor's on a $150.00 helicopter !!!!I for one don't think I will spend another $200.00 on just part's to go brush-less... On a $150.00 helicopter!!!

If you buy most of the stuff used on runryder or rcgroups here is the cheapest you can do it:

Leave the tail brushed:
$10 used brushed tail esc
$35 used cc10 brushless for main motor
$free rx - do the 4 in 1 hack
$40 used align hh gyro
$35 used eflite 370 main motor

Total: $120

go brushless on the tail:

$35 used cc10 brushless for tail motor
$35 used cc10 brushless for main motor
$free rx - do the 4 in 1 hack
$40 used align hh gyro
$35 used eflite 370 main motor
$30 new Fiegao tail motor or build a cdrom motor for $20

Total: $175


If you plan on going to Nitro then don't factor in the cost of the gyro since that can be used on the Nitro bird. Obviously if you go nitro, futaba 401 would be recommended.

Probably worth mentioning that I got at least 100 flights on my blade cp running lipos and the stock brushed motor. Also worth mentioning that a small heli is $less damaged in a crash than a Trex or nitro bird. I went seperates on my blade cp and absolutely don't regret it. The blade was my first helicopter, then raptor 50, then TREX, but I still fly the blade the most. Something to be said for it's size and the front yard.

thanks for the advice guys I think I'll just run my smaller lipo then let the motor cool, when I fly it again, cost too much to go brushless, especially cause I just got my new Raptor 30 V2, need to save money for parts on this one.

Thanks again

Tail stability on cp2
My tail is very waggy.. I've adjusted the gain and proportional over and over. I have it where it flying straight forward, and in turns pretty smooth.. When I try manuevering tail in.. Or descending in a hover the tail acts up.. swinging back n forth.. I figured the DD tail upgrade might help. Do I need a speed controller for it? Or can I use the 4in1?

Now if this doesn't fix the problem.. I would go seperates.. Esky mini reciever.. My stock 4in1 crystal should work I suppose and transmitter.
So I just need the esky mini reciever, esc.. 2 of them.. which ones for these brushed motors? 370 stock? the DD upgrade motor from gws? I haven't the slightest clue.. I need cheap escs for these brushed motors, but not complete junk.. Will they work with say a future brushless upgrade? Last but not least.. I would need a gyro.. Guess for tail stability.. I would prolly like the telebee heading hold.. But whatever is cheapest again, but not complete junk.. I need part #s. and a website.. thanks in advance.. I just want a stable tail.. Is that too much to ask? I've went through about 4 helicopters now. Walkera #4(most stable but boring) Venom3d (Pretty stable tail.. But glitchy) 22E (same as the Venom3d)Now a CP2 (waggy tail) which I really want to fix!
