I 'lost' my LA-7 today!

Not much progress this week but the cowl is ready for finishing coats!

 

After glassing the inside to regain its shape I then used P38 to fill in the 'scars' on the outside and a block of balsa stuck to the cowl to infill the bit that was ripped out in the crash (the bit that mates up to the wing LE). This was all sanded down then some 'Freddy's Sauce' applied as a sort of knifing filler and that too was sanded down.

Primer coat applied which will highlight any areas that need more filling although I'm inclined to leave it a bit on the rough side as this will give it a bit more of the weathered look.

More information, Tx - FrSky Horus 10 Express running OTX 2.3.13, Rx - FrSky X4R with ailerons and landing gear operating through SBus.

 

sorry to hear about your model  ?

 

what version of the RF protocol are you using?  ie ACCST 1.x/2.x/ACCESS?  there is an alleged bug in ACCST 1.x which possibly could be the cause.

 

out of interest - & unrelated to the thread topic - is it a vanilla X4R that you're running SBUS from, or an X4R-SB?  are you using the FrSky SBUS-to-PWM widget to run your servos/retracts?

there is (allegedly) a *very* infrequent bug with ACCST 1.x (which your 2015 X4R will be on if you haven't updated the firmware in the last couple of years) causing "channel output error (uncontrolled servo movements) under certain conditions".  I've been flying FrSky for ~8 years & I've never knowingly experienced it, but with my piloting, who knows?  ? 

 

(sparse) details here:

just be aware that you need to flash your RF module to ACCST 2.x too, which then won't work with any Rx's using ACCST 1.x

 

 

the reason I asked about your X4R & SBUS is that I have a number of regular X4R's:

that I'd quite like to get SBUS out of, & which I'm sure are only a solder bridge different from an X4R-SB, which does do SBUS:

(apologies for taking your thread OT)
