I wanted to try a darker hardwood and much thinner balsa than the last experiment. This time it is 1/16" balsa with teak veneer. The strips were glued with yellow glue and pressed overnight to dry. The teak was surfaced down to just a few thousandths on each side.

Next, a strength/weight test. I cut a very narrow strip and a wider strip of balsa of about the same weight. The balsa was slightly heavier and slightly stiffer, but I'd say these were fairly matched. No question that the teak was doing the work of carrying the tension and compression loads nicely.

There's probably a geometry of teak/balsa which exceeds plain balsa, but hard to optimize at this tiny scale.

I love the look of teak and I could create a slab fuselage with this technique that would look really cool. Tail pieces too. And I've proven I can do this without a weight penalty (especially if factoring in a lack of covering material).

As always, fun experiments with little need to have a practical application.

Hi friends
Need help. I bought on line a royal product Cessna citation 500 but it has no building instructions and I am unable to find it anywhere. Can any one direct me to where I may find this manual.
Thank you

My best friend, Bill Kubiak, had given me his blueprint collection (which didn't get to the fire place) of which I have started scanning, and I'm not to favorable of Office Depot, as there isn't but 1 person who knows what (she) is doing out of 12+ employees! There's nuthin worse than a 36" wide being (reprinted) on a 24" paper! Anyway, send me PM's for requests, as I have lots of space for messages, and all the PDF's are high res, wayyy above the RCG limits! No more werds, just some views! - Ohh yeah- a few of these will be 'reworked' in CAD for the 'foil factor', and a lot of these could be scalable. ...Continue Reading

Over the last 2 months I have been testing and playing with the Herelink system from ProfiCNC thank to the guys over a www.3dxr.co.uk who have been able to get me one to take a look at.

My main thread on this product Is below as well
https://www.rcgroups.com/forums/show...-From-ProfiCNC



Over the last few weeks I wanted to look a range and how this system would perform, Herelink is stated to have a range of 20km and I wanted to put this to the test, as laws prevent me from flying this in the UK I came up with a number of tests over some coast line to see what the system was capable of doing.

The plan was to set the Air unit up on a cliff mounted to a tripod and a camera, I also mounted a full cube system to it as well to be able to get full telemetry and test the FC control over the distance as well.



For the first test I found an area with a clear 10km 6m stretch up the coast line, I placed the Air end on the cliff about 25-30m above seal level and the plan was to stop a verbose points up the coast as I traveled along.

Project - "Glue & Fly Series" Nano Backyard/Indoor Plane Status #3 - Maiden Launch

Here is a link to the Video:
Project - "Glue & Fly Series" Nano Backyard/Indoor Plane Status #3 - Maiden Launch (9 min 14 sec)


OK, I decided to take on this side project as I have wanted an Nano/Micro Backyard/Indoor Plane for quite some time and I wanted to be sure it could carry a Micro FPV System so I decided to try and design one myself ;-)

This is Ground Zero, my Prototype of what I envision for this Plane.
It's much smaller that I had in mind so I think some upward scaling will be in order ;-)
I added 13mm to the trailing edge of the main wings which also gave me an additional 5mm of aileron control surface.
I also added 1mmx3mm carbon spars to the main wings to stiffen them up.
The AUW for this plane is now at 32.5 grams.
It's time for the Maiden Launch to see where we are and what we can learn.


See you in the Air!

Here are some flights from over the last couple weeks. I did some buddy boxing with some younger RC pilots and also did a maiden for someone at my club. Its always fun to help out others! Gotta do what is required to get as many people hooked to this hobby as possible!

Technically I never stopped flying. This winter was pretty tame. It just feels good to pack the car up in the morning to immediately hit the field after work.

Edit: Apparently it is an orange plane day.

Here comes the new Mugin-4 Pro 4000mm H Tail Full Carbon Fiber VTOL UAV Platform. It is a shell but with infinite possibilities.

Link: https://www.muginuav.com/product/mug...-uav-platform/

Dimensions
Wingspan: 4000mm
Length: 1900mm
Wing Area: 90dm2
Payload Bay: 560mm x 210mm x 185mm

Weight and Payload
Empty Weight: 8.26kg
Empty Weight with ARF Package: 17.6kg
Maximum Take-off Weight: 25kg
Payload Capacity: 6kg

We are always listening to what our customers say, and make the improvements accordingly to meet what our customers needs. The Mugin-4 Pro 4000mm is designed based on the Mugin-2 Pro 2930mm. With the same fuselage, but the winspan has been enlarged from 2930mm to 4000mm. The longer winspan means the cruise speed will be reduced, and the flight time will be increased.

The same to Mugin-2 Pro 2930mm, the new Mugin-4 Pro 4000mm is made with full carbon fiber. Much stronger and durable than the fiberglass versions.. This UAV platform is made in mold to make sure the replacement parts are the same.

Mugin Pro are the aircrafts with the vertical take-off and landing (VTOL) function that can hover, take off, and land vertically. No runway needed and much easier to save crash comparing to the standard fixed wings.

Today was a perfect weather day that started out (April 16, 2019) with cool temps (60F) but warmed up to about 75 by noon. Winds diminished to about 5 mph and no clouds. Lift was light but just enough for the Heron. I used the Lithium Ion (LiIO) charge setting on my $110 Hitech “Black” 2 pack charger. This puts about 90 percent into the Lipo 2200 3S 45 C pack and does not over charge the pack. On the first flight I flew for about 25 minutes using about 1.5 minutes of full power climbs. I only go full throttle for about 15 seconds each so this was about 4 or 5 climbs. After landing I had 55% remaining on the pack. I adjusted one flap and launched again into light but steady lift every where. After climbing to about 1000 feet and turning off SAFE Self Level I did about 1 minute of aerobatics with aileron rolls and loops. Max dive speed with SAFE on is limited to about 60-70 mph because the gyros limit dive angle to about 40 degrees. No wing flutter or flex was observed from the foam wings with aluminum wing spars. Energy retention is not like heavier fiberglass designs but is fun anyway. The full flaps and crow with full down elevator stick provides a nice 40 degree slow dive to a round out and flare right in front of you. The single wheel protects the belly and allows for friction free rollouts that are about 30 feet long . There is not friction on the wheel but if it had then this could provide for less rollout distance.

I am still learning...Continue Reading

I am relieved to find that with the gimbal attached the Son of FrankenSolo flies just as well as without the gimbal. I am disappointed to find that the logs once again not available. So I can't compare the power usage and determine if it is within the "C" limits of the battery. I am pretty confident that it will be fine but I am not going to do a flight time test until I know for sure. I am not willing to let the battery fail half way through the test.

I started out on this journey in 2012. I knew nothing about RC and RCGroups.com was pretty intimidating. I could not believe how many forums about so many different RC vehicles there were. I wanted to do an abstract photography portfolio that I needed an aerial view to do. I got a delta wing kite kit that was and is a very nice plaform but I needed to hover rather than fly to get what I wanted. I gave up until I saw an article about the new DJI Phantom in late 2013. I got excited about it like everyone and his brother. Until I realized it could only carry a gopro. But that was the beginning. I built my first DJ450 afterward. The first flight it shot up about 40ft and came tumbling down out of the trees out of control. It took me a full 4 months to figure out that the pitch in mission planner radio cal moved the opposite of every other stick if setup correctly. I built a dozen more aircraft over the years. I have a drawer full of half finished gimbals.

So this is a significant point for me. Only took me 6...Continue Reading
