After three months of nail biting, and some very tense tracking data, my XSRC MB339 arrived undamaged all the way from China. It was very well packed by the manufacturer Wind RC Production to prevent any damage. I was able to watch the production on Facebook live, and was able to request little changes as the production moved forward. I have to get the BTE Reaction finished before I start on this one. It will be powered with a Swiwin 140 with smoke, and controlled by a FrSky X20SE radio system, and Advanced Radio Smooth Flite 16 for stabilization. I will be doing a complete build on this for XSRC to help them with an instruction manual.
Dr. Tom I sent you a message about your panels. Definitely want to add them and the other improvements you have made.
I also have a question about the crinkled thrust tube. Did that happen due to the heat from the larger engine?
In case anyone was wondering, this model is very close to the JMB Jets MB339.

Goos job, it looks great!

2 Carlos,
Well better leave it as it is and then reinforce if something gives. But do a few touch and goes to get a feel for it at higher speed and then land if all is ok. And no need to reinforce anything


I would just suggest stro ger JP springs sonce stocl ones are for a lighter model (i have few pics and video woth difference before/after and it is worth it)

I took a landing gear mount out and that was my fault and we fly off grass. But when I went to fix it, there was gaps between the wood pieces with very light glue here and there. I love the plane and if I get another one, I would go through the gear mounts and make sure they have glue everywhere and maybe add some corner supports on under sides.

Its s a great flying plane and I did the same to mine. Some of the gear mounting blocs seem a little light on glue. I found a few gaps that I did not like and filled with hysol. But going through and checking glue joints is part of every build.
thanks,
Tone

Carlos,
You did not specify if all 3 retracts are acting up like that or only one?
and if it only one try to change its channel in JP controller. Maybe controller is fried and not retract.

if all 3 retracts do not work then troubleshooting can be done with 6V supplied to retract jack, shortly connect 4S NiMh pack in one and other ditection(polarity +/-) and see if it moves.
If it works that way it means that ehole JP controller is fried.

If you can hear grinding sound in retract engine most likeli its reductor gear is stripped.
and should be trplaced.
But since we are talking about JP they have great customrr service and ship parts cheap and fast.
