My brushed Traxxas mini e-Revo (1/16th scale, MERV for short) tends to cook its supplied NiMH battery unless lots of care is taken to drive slow or make frequent pauses. The amp draw is simply too high.

I searched around and decided to buy a pair of LiPO batteries from HobbyKing and connect them in parallel; thus dividing the power load, increasing drive time by 3-4 times and getting the left-right weight difference balanced. The original NIMH is in the 1200-1500 territory and the choice I made was two Zippy Flightmax 2s 2200mAh. I think they will handle the brushed 12T motor with ease. Getting 4400mAh, less internal resistance and less heat should increase both speed and runtime.

As usual, all connectors are different depending on manufacturer. The Zippys have XT60, the MERV has Traxxas. The Tetons have Tamiya and my planes have Multiplex MPX M6; mainly because I have had a number of RR and RTF Multiplex planes.

I did not want to start supporting Traxxas connectors too so I spent some hours changing connectors and making a few adapters and a parallel Y-cable for the MERV LiPo set using M6 connectors. The NiMH from the MERV got a Tamiya connector to fit the kids Tetons and the HK crimping tool worked great to clamp the Tamiya pins.

The last thing I did was to bring out the multimeter and checking resistance of a few different adapter combos and all seems well. Looking forward to the test drive!

AT&T plans to use drones to provide cell service at concerts. They have the idea to build cell extensions into drones and flying them. The service provider is already using drones to inspect the cell towers.

My first battery on fpv yesterday. Wow it's harder than I expected, trashed all the props. I guess outside or a hall might be a more suitable location than the lounge. I became very quickly acquainted with the furniture, light fittings and curtains.
I think it's the lack of peripheral vision thats getting me, and what is an easy to fly, incredibly stable aircraft became what appeared to be uncontrollable.
Soo it's practice, practice, practice.........
Happy flying !!!!!!!!!

** It's better to check the lift force before letting the balloon go,
if it goes up too fast you should slow it down a bit by adding weight. I used Electrical tape.

The latest and greatest thing is IOM racing here in the PNW. Its a blast with racing every other weekend at local lakes or every Sunday up north near Deception Pass. The IOM stands for International One Meter and the hulls are one meter long. They are the thoroughbred race horses of the RC sailboat fleets. We get 15 to 30 boats attending the regattas and then we all go and have a beer afterwards....Continue Reading

I maidened my GWS C47 today and got bit by the early takeoff tip stall due to the high wing incidence. Damage was minimal but the nose took a pretty good hit.

The video below shows how I repaired it with Foam-tac Foam Finish with no sanding other than the initial prep to remove paint and take the ridges down.

The Naze was good, but wanted to run more services and faster PID's and with Xracer F303's almost the cost of F1 targets, why not.

Having only 25mm between lower and upper deck, and wanting to run the VTX over the stack for best weight distrib, i used a socket to keep everything low.





Flew 200 packs on it now. Turned cam mix on BF on and have been flying mostly that now.



Bought a 2nd hand frame as a backup and started building that as a hot spare, but also so that i can test features on one, always having a good solid other. Also, as same frame i can move things from test to production pretty simply.


In Moshy, i ran the esc signal, power and battery lines in between the lower decks (4mm due to arm thickness) Im not going to do that in this one due to;

- I don't really need all extra room that it gives
- I want to simply for when field repairing
- Save time on carbon prep, as i ran wires through CF
- Its extra places for water to stick, which takes long to dry out
- weight of extra wire length needed for some runs

Im also not using a Afro PDB down there, just going to run the raw MXK PDB.

Also note xt60 connector, thats my new mount point.
I never liked the power cable coming out the rear, it always takes load in a rear end crash, so it had to move.
One is very limited to how they run the pack wires due to the prop coverage. I measure the thurst point of the props to see if mounting pack undernieth would work, but it would change the...Continue Reading

As I'd pointed out a couple of entries ago, my ten-year run as an official RCGroups.com reviewer will come to an end after the publication of the two reviews I'm working to complete.

Since I'm a member in good standing, I'm able to do what many of you have done, i.e., post product reviews right here on the blogs.

I've cultivated a terrific relationship with lots of vendors, among them Banggood.com. Not long ago, Banggood put out the call on the blogs for product reviewers. Since I've already done a lot of reviews on their behalf - including the two I have on the electric flight page at present - I was accepted into the fold, as it were. It's my promise to continue to be unbiased since these are, after all, reviews and not ads.

So, my new contact "BG Well" offered up a couple of tasty little entry level RTF multirotors.

One is the Eachine H5C quadcopter with its outstanding HD video/still camera. The other is the fun new MJX X600H hexacopter with its WiFi camera system.

Some videos and more detailed reviews of both machines are forthcoming, but for now, let me simply say that both of these machines are worth considering.

The link to the Eachine quad's ordering page may be found here and the link to the MJX hexacopter may be found here.

Pictures from our 30th Annual Fun-Fly, held July 8th, 9th & 10th.

While the wind worked to keep everything and everyone from over-heating, it also stifled flying activities a bit, but since it’s common for us to sit around and talk about airplanes as much (more?) than we actually fly, it still made for a great weekend.

Despite the fact that no fees were charged, attendance by both pilots and spectators was lower than normal, and we’re left wondering if the date change (moved up a week due to a conflict) made it too close to the 4th of July celebrations for some to attend.

We served fewer hamburger at the Saturday night barbecue, but as always, the food was great and it seemed everyone enjoyed a good hour or so of conversation before flight activities resumed. Thanks to those who attended and brought something to share!

Planning for next years’ fun-fly started the next day, so as always, we welcome your comments and suggestions for next year....Continue Reading

The new Hubsan 502E Desire,what a neat little quadcopter.This Quad is pretty cool.First off,it looks cool,I like the styling of it.Next up,it is small an a easily portable video and picture taking qaudcopter.Now its biggest feature ,this little guy has GPS : So far this is the smallest quadcopter that I have seen with GPS and it works well,I found it did take a minute to lock in on the necesary satelites it needs to use its gps features but once locked it held in and I could fly it out far enough that I was barely seeing it the hit the return to home function and it came back reliabaly every time
I will be posting more on this one soon

So as I stated several posts ago, this is the first K&B engine I have owned. I am both impressed and disappointed in this engine. Let me explain. I ran it today for the first time. It would not hand start which is not entirely surprising, but it did leak fuel, badly.

Once I got it started with the electric starter I ran it quite rich as the instructions mention. I saw tons of fuel leaking from the rear of the head. Initially I thought, hoped, it was coming from the carb inlet. Well that did not turn out to be the case. It was coming from the top of the head, as seen in the videos, and running down the back of the engine pooling up in the rear of the back plate. Now the impressive part of this is that the engine was running well the entire time! I mean once I got it started, it never missed a beat. It would idle well and transition to WOT was good. The engine runs good.

So after the first two runs I took it inside and opened it up looking for some gross manufacturing defects that would be the cause of this leakage. I shot a video of that too. Well I really didn't find anything unusal but I did apply some Permatex motoseal 1 ultimate gasket maker grey around the mating surface of the top head piece. After re-assembly I ran the engine again, again I shot a video, and the fix seemed to work.

There are 3 videos linked to this post. Watch them all if you want to see the progression of the first runs, dis-assembly, and subsequent run of this engine.
