I am getting my OMP M2 explore FC to have a brain surgery.
The stock FC uses the STM32F303C8 processor which has 64k of FLASH memory, 16k of RAM memory and contains no DSP instructions.
It is now being modified to have the STM32F303CC processor which has 256k of FLASH memory, 48k of RAM memory and contains DSP instructions.

This post was initial posted in the OMP M2 thread but I have decided to keep that thread clean and dedicated to the M2 topic only.
Hence this thread is being created. I'll post the progress as I am moving along together with the result or outcome.

The M2 with new STMF3 processor will be running with the HF3D firmware.

I have mapped the pin out of the stock FC and ported into HF3D. It was successfully compiled with no errors.

Many cracks & deformations have formed. It definitely isn't as robust as coroplast. The lion kingdom began desiring an Ender 5 Plus. That could print the entire panels in 1 piece. Quantitative easing being what it is, the cost of the printer isn't the issue. The issue is the $5 million in real estate to put it in.

Just a pic I missed from 2 posts ago, showing how I squeezed those laminations tight.

I have to now decide what power plant for this model.
I have 4 potential engines all ic as I have absolutely no interest in electric.
1st is a trusty OS 91Fx two stroke glow, the main problem is weight or lack of it I'd probably end up with about a pound of lead to make it balance and the muffler would stick out like a sore thumb.
2nd is a really old laser 100, at first I thought this might be marginal but the authority with which it pulled my 1/4 scale Cub through loops is very reassuring.
3rd is a nice new OS 120 Ax two stroke, with the 90 degree exhaust adaptor this keeps it neater than the 91 and it is heavy enough and the power is prodigous.
4th, and favourite , is a turnigy 26S gasser this is a cracking engine so smooth and powerful, bit light and also a bit flimsy but it spins an 18x8 well and I have a muffler that actually works on it.
Any advice readers can give would be gratefully received.
Plane comes out at about 11 lbs.

First attempt at laminating longerons, not a great problem except the wood is 1/4" whilst the carbon strip is 6mm. Not a great deal and I can spackle it.

Well good people, came with something different and not available anymore (discontinued for a number of years). I got this from a friend (David McCullough) a few weeks ago. It is the ElectriFly GEE BEE of 38.5 inch wing span and tips the digital scale at 2lbs.-1 1/4 oz. with the 3-Cell, 1800mAH, 30C, Lithium Polymer battery pack. The Center-Of-Gravity is at 1 - 1/4 inch from the leading edge and you really need to pay attention to this as this model is very sensitive to incorrect C-of-G setups.

This is my first flight of any GEE BEE and read all the reviews as to what for setups, take-offs and landings and memorized with my brain and thumbs! Early this morning I touched UP the model with my Models Acrylic GUARDS RED to those areas that experienced less than perfect landings. It cleaned up very well with this paint.

Took off slowly as per reviews and increased power slowly as well and it tracked very well with little or no rudder correction. It came up on the mains quickly and allowed a sufficient roll-out and carefully pulled back on the UP elevator and it took off without any issues. Once airborne, it performed like it was on rails! Hammer heads, Cuban-8's, and it maintained some Knife Edge flight as well. Inverted flight was natural for this model.
Need to keep it with the 3-Cell, 1800's packs as the 2200's are just too heavy for this model. The 1800's allow for gentle (kiss the ground) landings so, it is a keeper!

Hi All, this week after my video and posts on RCG and other placed CaddX and DJI have stated they will no longer be encrypting camers that are not licenced for use with the DJI FPV System on the CaddX Vista.


If anyone's want to know in's and outs of all this and how it happened I explained it here in my update video on the situation.

DJI Digital FPV & CaddX Update - No Camera Encryption & Canvas Mode To Come
DJI Digital FPV & CaddX Update - No Camera Encryption & Canvas Mode To Come (11 min 10 sec)


A few last comments on this all from me.

This is the 3rd time I have been at the eye of the storm on this and im pleased and proud we all have been able to get a result here. For me this was never about pinning it to DJI or upsetting CaddX, it was my open and honest thoughts on what I felt was just wrong. If it was not for you guys commenting and sharing the statement I put out and the video we would never have got the result.

While I may have been the mouth piece you were the guys that made it happen period.

As I have said already there were lots of messages back and forth with both companies after I put everything out and both sides were really friendly, I was glad I was also play a small part to help on the Canvas thing too and I will talk about that more some time if it actually come to fruition.

There is a hell of a lot more I could say on this and how it played out as there are some things im a little 'hmm' about on the whole thing however im going to leave it and I now intend to get back to trying to do what I love to do and leave some of the politics behind for a while, my intention on all of these 3 times now we have got a result was never to become a PITA but to help the community and that's what we have done.

I finally want to thank everyone for the kind words and comments and all that's left to say is outstanding work all.

Having slept on it I came up with a plan B for the construction of the longerons.
I wanted a greater cross sectional area (csa) and also wanted to be able to contain the whiplash forces that frequently arise when landing on our not so smooth strip.
I've attached a pic which kinda shows my plan .
Building the longerons like this also gives the advantage of having outward facing wood for the solartex to adhere to.
I also changed the adhesive from gorilla glue pu to cyano as gorilla glue is dissolved by cyano in my experience so this choice allows me to use thick cyano to glue the longerons, braces, formers and stringers in without having to worry about contamination.
There'll be more shortly.

Making progress with my very ambitious project to design and make my own outboard. In a few weeks I have learned how to use a cad drawing program, mainly from watching you tube videos. I was forced to do it myself as it would have been too much , timewise to get someone else to do it. It's been very enjoyable I did lots of practice drawings to learn the skills.
My next ambition is to find the funds for a 3d printer, then learn how to use it. Watch this space.
My outboard is going to be a good size maybe 11" top to bottom , it will have a large powerful brushless motor, 40 x 80. 1600 kv
Batteries will be 2 x 3s giving 6s power . The top gearbox bearing and oilseal will be removable so I can do oil changes, this will save having fill and drain holes and the plugs. It will be filled with hypoid gear oil like the full size. I hope the helical gears will be quieter and have a good lifespan.

I’ve been watching the EAA AirVenture air shows on YouTube, using my big TV with the YT app. In one of them they had an extended demonstration of 5he Goodyear blimp. This one is a new design to my eyes. I remember the one that had regular aircraft engines on pods near the gondola. This one has three electric motor powered props that move as needed. It appears there is a engine powered generator at the back of the gondola. It is also a sleeker gas bag than previous and only has three stabilizers instead of the four I remember.

So it’s a giant multi rotor supported by the neutral buoyancy balloon.

Here’s a picture my friend Lee Ray posted on FB

It's been over two years since I wrote here, tbh with all that's been going on I haven't done much modelling wise.
Now I have several airframes to repair, a sig 1/5 scale cub, a hangar 9 1/5 scale cub, a modeltech 1/4 scale cub ( I like cubs!) and an airframe I bought of a scaled up Ruhig Tiger.
This is the plane I'm hoping to repair.
The original design was published as a plan in one of the UK magazines in the 70s I think, a 60" span sport aerobat, low, thick wing fixed u/c for a 45 two stroke.
The designer made some rough drawings of the scaled up version at 72" span but regrettably died before he could build it. His widow gave the drawings to one of his friends who copied them and gave them to one of his friends who built the airframe.
He got about 90% of it built when he decided enough was enough and I bought the whole kit and caboodle off him.
I finished the airframe without the benefit of plans though I had some reservations about some of the timber. I covered it as an american trainer very much like the PT 19 and it had a royal blue fuselage, yellow wings and stab and candy striped rudder.
The reservations I had were with regard to the longerons which were very soft balsa but I persevered and had several flights until one day it ground looped and the subsequent whiplash effect shattered the rear fuselage which was a box like structure of longerons, cross braces and stringers.
I made several plans over the years for the repair including buying some 6mm square carbon fibre tube but today I sliced some 1/8 x 1/4 from a sheet of 1/8 ribstock balsa and have 6mm x 0.8mm by 750mm carbon strip that I intend to laminate together the form the main longerons.
I've started this blog so it will encourage me to get on and do it as it's my 77th birthday in a week or so and I want to fly it on that day.
I've added a pic of the components for one of the longerons so it'll give you an idea

Hi fellow rc pilots & rc enthusiasts

WOW, I could not believe how lucky I was when I watched this video recorded on the sd card. In waypoint mode I lost sight and then also fpv ??? Hit the RTH button and it came back. I should have taken this up to 30 meters in the first place and I am grateful that it did return :-)
