Yup, I also thought his service was great when I had one of his motors replaced. But what kind of chimp has he got in the back doing all the cold joints? When I was replacing the connectors I had one fall right off in my hand.

Thanks
Mine hand launched fine on the stock 4s setup.

I have been soldering all my motors to ESCs a long time now and dont have to worry about that.It also makes a smaller area to feed through ducting.Since I use mostly CC ESCs I do not worry about rotation,can always reverse that later.

I was asking about 5s setups(heavier lipos and esc), 4s has not been a problem for 2 years now.

We got a nasty rainy weekend over here on the north west coast...
Makes for a great day to teach the little ones how to fly the H2 on the Phoenix simulator!

I have now located the problem and turned out to be bad factory soldering on those motor lead extension wires. I have now replaced them with 12awg silicone wire and soldered them directly to the motor this time.



I actually prefer doing it this way but was surprised that this was the condition from factory. I was really lucky to not have had a crash as this is already a replacement plane from HH.



I recommend to everyone to solder the leads directly.



Has anyone tried using dielectric grease on connectors? This product claims to enhance the connection and prevents arcing and damage to battery connections.



I use dielectric grease on large electrical connections, where the material is not the best conductor, like aluminum or tinned bronze, and are bolted together. Di-grease is also used on conductors that are of dissimilar metals and can corrode, or are prone to dirt, grime, and moisture. Most connectors that we use on rc equiptment are gold plated and are press fit, and moisture is minimal. I don't think you will see a benefit from using any grease. But if you do, let us know if you see any heat redcution at connections.

And as far as soldering conncetions, toatally agree. When feasable, a soldered connection is the most secure and less resistive of all connections.

100 amp ESC duct installation

I spent the last couple of days pondering how to avoid a hornet's next of ESC-to-motor wires because of moving the 100 amp ESC to the intake duct location. The challenge was how to go directly to the motor wires without using the three 15 inch stock motor-to-ESC wires.

What I did was deconstruct the back of intake duct and cut some channels inside to permit the three motor wires coming from the ESC to go directly to motor wires. Now I avoid a mess of wires in the back of the canopy area. The bare airframe's extension of the three motor wires are removed from the channel pocket because they are no longer needed.

Take a look at the three pictures. I think it is self explanatory.

Hi Prof100, I really like what your doing and your ability to detail your photgraphs.
Trying to reduce wiring from excess servo leads, batteries and esc connections is a great idea to rid your plane of useless weight while making things look neat and tidy.
Looking at your pics here it appears to me like you saved yourself a couple inches of wiring by running the leads straight into the channel as opposed to going through the chase first. Or am I wrong? How much wiring did you manage to remove?
I would like to be able to make my own servo leads, removing any y- adaptors or extenders and making each servo have just the right size tail or splice needed. Where does one find the tools and materials needed to make custom leads?

I removed 45 inches of 14 gage wire (i.e., the 3 stock motor to ESC wires which are 15 inches long). Besides saving weight I have eliminated the twisting, turning, looping back and tie wraps.

This type of modification, while looking easy, burns up a lot of time planning to make it work. It's the old "measure twice, cut once" rule.

Ah ok I get it now! You will probably get better performance from your esc as well because they read voltages back from the motor, and long leads and multiple connectors will induce voltage drops.

Good point, the shorter wires are always better than long for voltage drop.

And, thanks for the kind words about photos detailing the modifications. I do that because I know when others come up with new ideas I appreciate it when then they take the time to document with pictures and explanations.

Are you guys putting any spars in the wings for strength? Also, watch the elevators,before I installed CF ribbon they got sluggish at top end speeds,I did notice after I added them it was much more crisp in response at full throttle,

I have not made the decision whether or not to install any CF reinforcement.
