I have a 3 quad with 1408 motors and I have HQ3x5x3 props. I have been running 3s on it with out any problems and recently I tried to run 4s. Half way through the throttle the whole quad would have a shaky effect through the googles, I could also hear it vibrate a lot. This is alittle concerning bc my thought Its the props and the props are big as I can get on it. If anybody could help me identify the problem that would be great.

It seems the last four years have gone by quick.
For some reason (family trauma), I dropped the hobby.
As it turns out, slope soaring is just to much fun to leave alone.
So I picked it back up and revisited a few foamie glider ideas that have been collecting dust in the back of the skull.
The flytrap was a huge success with the new way to fold the KFm2 wing design, which I call the KFH.

It works so good, I went back to the revert and added the KFH foil to it and WOW, it's even more fun than the flytrap.

Here's a quick peek of the maiden for anyone interested in building a dirt cheap and fast building plank.

I started flying R/C with my dad around 1979, I was 8. My dad was a pilot with a commercial rating and thought he could teach himself how to fly R/C. I remember him building his M.E.N. Trainer in the dining room and the smell of glue flowing through the house. We joined AMA and the Goodyear Model Airplane Club and come spring he and I were ready to go. The first flight lasted about 15 seconds, even after he was told not to try it on his own. He had a great attitude about it and we collected the pieces and made a quick rebuild. Two club members were instrumental in training my dad, Paul and Carmen got him up to speed pretty quick and all was well with the world. By the end of the summer he was on his own and starting to teach me. We built a small glider called a Piece o Cake and with the help of Paul and my dad I was flying pretty much on my own up to landing. That fall dad helped me build a Pilot Baby with an .049...an engine which gave me lasting scars on both index fingers. He built a Sig Kadet, both airplanes we test flew in late fall. Right before Christmas that year he solo'ed me...something which I will never forget. The journey had begun.

Crosswind is a new twin motor FPV platform for professional UAV needs.
The main wing is updated with a new shape of the airfoil, which greatly
improves the lift-to-drag ratio and especially the lift when in low speed.
Crosswinds wingspan is 10 cm larger than that of the MTD
1800 mm while the wing is wider and the fuselage longer.


It's now available on fpvmodel website for only $179.99: https://goo.gl/RzL3JT

My second EF Laser v2 74 is almost RTF! I just need to do the basic test and set up for the engine in my yard (I don't like surprises at the field), and make + install a custom push pull rod for the rudder. I will include more notes at the end of my build.

Key highlight is that gas is absolutely push pull for rudder, unless you are in the mood to add 4+ ounces to the tail. I am using a combination of bigger batteries on the turtle deck, and roughly 42 grams of weight at the tail to get the static CG roughly right based on my electric Laser.

To make a 200 mm custom push pull, my solution is to get a 4-40 all thread rod, a sturdy CF sleeve, and use the Loctite plastic bonder to lock the 3 mm ball link on to the 4-40 all thread rod for life. I tested this first with a spare piece of 4-40 thread to confirm it is exceptionally solid. I will include a pic when I am done with it. Right now waiting for the 4-40 all thread rod to arrive.

Equipment:

Falcon 20 x 9 CF prop
aluminum spinner
DA 35
stock DA muffler
MKS 1250 throttle servo
MKS 1220 surface servos
EF servo arms
EF tank
Plumbing from JerseyModeler
iBEC from TechAero

Radio and related:
10 channel Jeti receiver, DSM 10 switch, R/3 SW remote for DSM 10 switch, and a pair of 2S Lipos.

I have 2 x 2S 2200 Pulse (100 grams each) and 2 x 2S 5000 Glacier (200 grams each). I will likely start with 2 x 2S 5000 and adjust from there based on flying CG....Continue Reading

This review has been written by a young friend of mine who is looking to contribute to my website more regularly.

This is his experience as a relative newcomer to sub 2" micro quads, specifically those suitable for indoor flight. Full extensive review is here:

I truly believe that Horizon Hobby has done their homework on their new 1.5m AT-6 Texan, as it is my thoughts that it is not only the light weight (low wing loading) but, the Airfoil shape they have developed so, it will not snap like a typical AT-6 airfoil and still have that scale look of a AT-6.

The devil is in the details and they (HH) has dealt with the stall thingy head-on and I am very pleased with it's ability of float in on landings so much at a low speed that a typical AT-6 airfoil will snap no matter how light you make it.

If "Anyone" has any doubts or interested in the Maiden Flight of my E-Flite AT-6 Texan then, I welcome you all to go to:

The design of the Lama V4 adopts a co-axial and counter-rotating system which makes it most suitable for indoor flight. Its characteristics are: easy controllable flying, simple operation and quick re-charging. The "4 in " mix controller integrates the functions of Gyro, Mixer, ESC and Receiver. Two superior 180 motors and one 7.4V Lithium battery offer powerful performance and long flight times. The canopy can be taken apart and re-assembled easily, allowing adjustments and repairs to be made very conveniently. It is also attrac-tively finished and practical.

There's been a lot of progress since my last post. I'm going to write it up in a few "installments".

In this installment, I shaped the elevator. It needed a taper from the leading edge to the trailing, and a rounding-off of the ends. I was nervous about being able to make the taper flat and even along the length of the elevator, but I was patient and sanded it with long even strokes, and I'm pleased with the outcome.

In Part 6, I had broken a former, which I easily glued back together, and promptly glued upside down in the fuselage. I wasn't sure at the time what the impact would be, so I didn't do anything about it. After the formers were in, I installed the tow hook block. Shortly after I realized I forgot to glue in the very front most former (to which the firewall is glued) which holds the sides of the fuselage in a taper toward the nose. I braced the 2nd former so it wouldn't buckle while I clamped the nose together to glue the former in place.

Next came the 3/16" sheeting for the bottom of the fuse up by the nose. The instructions suggested dampening one side of the 3/16" sheet to help in bend, which I did. It seemed to do what it was supposed to -- the balsa bent on its own due to the uneven moisture. It took a lot of pins to clamp that in place while it dried.

Surprise... it curved because it swelled on the wet side. After it dried, it shrunk back down and left gaps in the sheeting -- maybe 1/32". Not sure if that's a problem or not, but I filled them in with slurry of Titebond and balsa sawdust.

Video of my FT Super Bee (nicknamed Zipper) on its maiden flight and crash. I was using the high performance motors (red bottoms) and 4S lipo. Due to the quick speed and cramped space I overcorrected to avoid the tree and down she came. Damage was actually pretty minor. The plane is a little speed demon!

I acquired this one from Dave Walter at the Walter RC Park in Saranac Mi, and it was just the cut foam only. It is a West Michigan Park Flyers "McFoamy" but it was one of the early kits which is no longer produced. I finally received the missing wood and carbon fiber parts for it and started the assembly yesterday. Covering is colored packing tape I had leftover... Uncovered assembly Pics are from the WMPF site as I did not take any during the assembly...

I finally got this Alpina back together. It had a devastating crash that snapped the fuse in half and folded the nose over. It took a lot of fiberglass cloth and Bondo to get her back together. Luckily the repair only added about 4 ounces.

I did a build thread over here:
