Got two new quads in the mail today, one tiny and one big. The WLToys Q343 is particularly interesting since it uses a smartphone for control and it transmits live video on the phone as well. It even has altitude hold! I'm curious to see how well the smartphone control, barometer and camera works in practice in such a tiny little thing.

The Syma X8HG is a 350 sized quad with a 1080p GoPro style camera. The candy apple red strikes a nice contrast with the silver stickers and from my experience with the X5HW, it's little brother, it'll fly just as nicely but with a much better camera.

Both reviews of these will be out soon, right now I'm working out on it.

Can a good RM1 airfoil be designed? Yes, it can. According to the xflr5 analysis smoothed RM1 (RM1sm) can perform suspiciously well.

Below are the two RM1sm airfoils that I came up with that are quite close to the PW51 airfoil at Reynolds numbers in the 50000-150000 range. Notice the conventional rounded/smooth leading section and the flat sections aft of it.

Took the Monterey to the Hill last weekend for its first flight. There was little to no wind with a slight breeze at times. The first flight required some down trim and it was apparent I needed more rudder throw, so after a few short passes I landed the plane. I added a bit of nose weight maybe 3/8 of an ounce and went back on the elevator trim three or four clicks, also moving in one hole on the rudder control horn. The second flight was a blast as I encountered lift soon after launch and circled right on up having to leave the lift several times to keep from getting to high. The Monterey has no spoilers so I was being very careful. The adjustments were just about perfect. It's been a long time since I have flown a larger span rudder/elevator sailplane but like riding a bike it came back to me fairly quickly. The Monterey is fairly light and climbs very well but you have to think a bit ahead while maneuvering as things don't happen as quickly as an aileron equipped sailplane. Overall the Monterey is very stable and beautiful in flight and she didn't display any bad habits, almost certainly why it was my first really successful rc sailplane back in 1971 or so. The landings were very smooth and predictable but the landing pattern will have to be adjusted to compensate for no spoilers i.e. a bit larger and lower than usual if there is no wind. I can't wait to fly her again, this time maybe launching with my up-start if there is little or no wind., saves a lot of walking I should add that way back in 1971 I had not learned how to thermal or even recognize thermal lift so this series of Monterey flights were kind of special.

June 17/16

As luck would have it, I woke to find the air absolutely calm! Hmmm…..time to go flying! However, the “Commander in Chief” intervened with the need to be driven to the grocery store first! By the time, I returned, loaded up the plane and drove to the nearby covered reservoir, it was 11 am. The temperatures had risen to 30 C and with it, the incessant wind, which was gusting from the east at 15-20 Kms. Dang not the best conditions to testing my HK Cumulus DLG!

Following the advice of some fellow chuckers on the Hand launch forums, I decided to add a thin ribbon of lead weighing at exactly 5 grams to the nose of the plane. I also rechecked the aileron differential setup again and sure enough….I had the settings reversed! Doh! Also, performed some more adjustment on the right aileron to line it up with the wing.

The good thing was the grass was getting on the long side at the reservoir which makes for softer landings. The bad thing was the wind speed had picked up and was gusting! Horrors! I don’t feel comfortable launching and testing a new bird in such conditions but I was here now… I decided….let’s go for it!

I was delighted to see the Cumulus actually fly like a DLG is suppose too! I wasn’t throwing very hard and so I wasn’t getting much more than 30 - 40’ of height. Non-the-less, it went up on the shelf quite well and penetrated the wind with ease! I actually had it hovering in the wind at one point.

I got in about 10 good chucks and was...Continue Reading

test no.1

Sunpower Maxeon C60 - solar powered rc plane setup - test no.1 (3 min 18 sec)

An 120cm delta wing needs around 30w for cruise flight.
60mins on 5ah 2S battery. Flown 2 years ago.
Small 2200 kv motor with quality aeronaut 9x6" prop.

So I am building a setup for it (30 w const or 60-80w bursts with glide periods)

Will test what delta likes better

Eachine TS840 and RC840, 40 CH, 5.8 GHz combo review.

The following review is based on the units provided by Banggood for review porpoises. The comments and results reflect only the point of view of the author.

Shipping and packaging:

The units came on separated labeled boxes, well protected. It took 35 days to get in my hands for review (Average time to Brazil).


- Board: TS832_140909 REV:1.3
- Dimensions: 31x55x8 mm + antenna and cables
- Weight: 19.25 grams + 5.08 grams (cable). The weight is more than double that Eachine ET600R and similar.
- Current consumption: Testing with a 3s lipo (11.6v) it consumes 0.3A. Interesting or not, the output voltage provided to feed the fpv camera was 10.4v (1.2v less than the input provided by the main battery).


- On the side of the main board there is an empty space corresponding to (looks like) a serial connection marked as V R S G (voltage, receive, send, ground). I didn’t tested but it would be nice to hear from BG what is that port for.

- On top of the +12v input there something like a potentiometer that can be adjusted using a screwdriver, I don’t know what is for yet, maybe to regulate the power output of the unit…

- There is a built-in Mic on the bottom of the unit (There is not connection for an external Mic), I will record the sound with my video grabber to check the quality.

- The band/channel display is not easy to read on a sunny day. Two big buttons allows to surf...Continue Reading

We have been supplying custom tuned (center freq) Yagis to many customers including RCGroups members all over the world everytime with awesome long range vedio results.

So what makes our Custom tuned Yagis perform so well ? . . .

Whilst other Yagis, in general, are made to sell, they are not made to be used, meaning… a lot of marketing hype, overrated gain (dbi) and it is common for the industry to produced extra elements so it looks extra super duper long.
Being mass produced, fine-tuning is neglected.

Batteries and Antennas are much alike when it comes to the labels on them, C rating…. Gain (dbi), just overstated numbers. for more details.

It's getting very hot here in the desert, so before it does, I decided just yesterday to fly a couple of fun models which I hadn't flown in some time.

One was the Multiplex ParkMaster PRO and the other was the fast and fun Ares Advantage Decathlon 350.

The PRO genuinely loves up to its name. It's a great sport plane when the throttle is opened, but as anyone who may have seen the indoor demonstration at this year's AMA Expo can attest, an accomplished 3D pilot can do amazing things indoors. Just fantastic.

The compact Decathlon is a little screamer; it's probably faster than a plane this size has a right to be. Aileron control in the unassisted mode is touchy, but will allow the Decathlon to do loops and rolls which the onboard flight aids prevent when engaged.

I upgraded both the ESC and the original battery with Deans micro connectors since the Electrifly battery I'd bought as a second battery had that greatly improved plug. Much better than the JST and noticeably more power.

Only glitch is an intermittent ESC which reared its head with brief losses of power. Oh, and I managed to catch the undercarriage in an unseen hole in the grass which tore it out as I was landing. All fixed now and I may install an 18A ESC which I have on hand for the time being.

The original review of the PRO may be found here and the Decathlon review here.

Schools out and I spent yesterday down at the beach with my family. I lie on my back, lazyily watching the sky for anything interesting - be it man-made flying things or birds.

Up north at LAX there's constant activity and the jets glitter in the air. Above me traffic from the Pilatus PC12s; a favourite of mine as they look so cool and sleek in the air. A Rutan Long-EZ passes by heading out to the sea, easily distinguished by it's profile and the peculiar hard sound it makes.

Once in a while the GoodYear blimp goes by, floating eerily with only the front tethering line betraying the forward speed. It runs up and down the beach, turning around just south of the marina, and making a great racket as the engines rev and the nose turns up to gain altitude after the turn is completed.

A white camera drone pops by and hovers briefly over the lagoon; gradually descending with the front camera aimed at the sunbathers. Few seem to notice but it doesn't feel right and I glance around but don't see the pilot anywhere. It disappears quickly to the north.

In the next few days I'll be setting up a sim for my brother and a friend just sent me a pic of his newly arrived AXN FJ but for now, it will be sun and summer instead of RC!

Hi guys

I have been shopping online for a while now but i have never come acrossed sellers like the ones on Aliexpress who can lie and cheat,mislead people!!!Now the question is though how come they are allowed to do business internationally when they are unreliable? just recently i i had to deal with sellers who are misleading customers by posting fake ads and sending out wrong items,either something is wrong with the item or they sending completely different items to what they advertise!!! This is serious issues since customers are buying without touching goods and trusting Aliepress with the sellers they have but customers are the one who suffers the most! There are some sellers who advertise on thier page that they are liable for return shipping fees if the item they send out is wrong but the sellers dont pay the return shipping fees..Thats absolutely "BS" why advertise on your page if your not going to pay for it...????? SO if you want to do online shopping from Aliexpress be very careful because some sellers are liars,thieves and scammers!!!! Aliexpress doesnt even have any sort of contact number that customers could call and solve thier issues! This is not something that you want to experience trust me its frustrating
