Hey Logo Gurus,

Here is my preliminary build spec for a Logo 500 3D (flybar'd for now) on 6s 5000mAh packs. I'd like to get 6-7 minutes of basic 3D.

Please take a look and see if it looks good, you'd suggest something different, or if something's missing. I'm not quite sure if I should get both (or additional) pinions. This is my first Logo.

- Logo 500 3D

- Xera 4025-2Y motor

- Mikado MIK4218 18T herringbone pinion M0.7 5mm diameter

- Mikado MIK4219 19T herringbone pinion M0.7 5mm diameter

- Kontronik Jive 100+LV ESC

- (3) Futaba BLS451 servos (cyclic)

- Futaba s9254 (tail)

- Spartan ds760 gyro

- Mikado MIK4075 (hardened main shaft)

- Mikado MIK3046 (Antistatic Tail Drive Pulley)

- Rotortech 560mm Pro 3D main blades

- Radix 92mm tail blades

- Spektrum AR-7000 RX/DX7 TX

Thanks for any and all input!

Dave

Looks good to me. That motor will be very efficient on 6s. I'm curious what ESC you're using?!

HI Dave

That Motor work well on 6s but i would Highly recommend running it on 8s
4200 packs

You will have no problem getting your 6-7 minutes of flight time

And the motor will never be over 105 degrees

Me and a few other s are flying this Motor in similar machines on 8s with excellent performance

I would also suggest a BLS 251 on the tail. You have great cyclics, you might as well have a great tail servo ........Ron

Hi Dave,

Don't forget tail blades. Here's what I'm using:

Be careful what you order. The grips are small and won't allow rotation of some blades.

Keep 'em flying.

Thanks guys!

CNCAddict, the ESC is a Kontronik Jive 100+LV (but might go 80+HV)

Bsmith,

I will not go above 6s until lipo prices drop more. If/when they do I'll probably skip right to 10s. I prefer to only invest in premium quality Lipos though and right now that puts me over $500.00/pack. I'd rather have more flights at 6s.

I'm concerened now as I was informed that the Xera 4025-2Y will need a 19T pinion to get close to the target (most effective) headspeed. Mikado doesn't make a 20T in mod 7.

That now has me looking again at a Scorpion 4020-1100. I just didn't want to have to deal with the bearing issue.

Ron,

The 9254 is supposed to be a very good servo and since I already have one I figured I'd use it to start. When I upgrade/replace, I will most likely go with a 251.

LJS,

For the tail I had Radix 92mm planned. OICU812 said the K&B plastic ones flex a little too much. For the price difference though I might try some just for the heck of it.

THANKS for all the tips.

Any other motor suggestions???

Dave

PS, If any of you know someone in the market for a slightly used E550 Raptor (about 80 flights) let me know.

Dave,

I don't think you really need to worry about the bearings on the Scorpion. I got the bearing oil and added it a couple times but since I'm not in a dusty environment its actually been fine. It seems the disclaimer about adding oil to the bearings came about because Scorpion didn't want to deal with warranties for free bearing replacement. It actually is no worse than any other motor bearings. I'll try to find the thread about this and let you read the details (it will probably be on the other forum that its found).

Also, I think you'll like the Radix 92mm tail blades. I have the Rotortech ones but like the look of the Radix more. I agree about the K&B flexing a bit too much since they would cause some chirping in hard piro moves. If your not putting the tail in the ground, CF is the way to go. Also, the taller landing gear on the Logo helps out with that. I've been running the same blades for over a year and all I do is use Windex to clean the grass stains off.

Thanks Bruce.

It's reasuring to hear that. If you find that thread (or any thread on Scorpion bearing problems) I'd love to read it.

I have a few weeks to go before I'll have my Logo ready anyway so I have a little time to decide on the motor. I think it will probably be the Scorpion though. My main concern is how hot they get?

It averages above 95 degrees here in the summer. I need a motor than runs on the cool side.

I was thinking about the Rotortech tail blades (since I'll have their main blades) but I'm going on OICU812's recommendation of Radix.

I actually have some yellow K&B's on my E550 Raptor that I could just take off to try. I don't remember what size I bought though. I know they were slightly longer than the stock tail blades.
