My spelling cud do with being improved. As my teacher's used to say - "Must try harder." Should be "couldn't" make out what the engine is ?

Unfortunately not my build. Always been interested in the Optica but put off due the fatal accidents a some years back. I could make out what the "engine" is but obviously something with lots of rev's. An excellent model but they do seem to fly a bit fast for my taste. ?

Do they have to foam cored wings ? Would built-up be lighter ? YouTube -

My own thoughts are the Taranis 9+ can be updated only with FrSky firmware ? It's the external module I thought could be updated with the MPM firmware. But re-reading it is a Frsky XJT module so possibly not - don't know. ? Even so the module could be updated to contain the FrSky X2 (D16) protocol to cover the R9 mini. Leave the internal protocols on the Tx as is. If updating to the EU/LBT version this may not have the D8 protocol as it is not LBT as far as I understand. ?

Is there some reason the external MPM module can't be updated to the latest version ? (or is it limited to just FrSky firmware ? ) The latest MPM update will give FrSky X2 (D16) which should cover the R6 mini. (as well as D8 etc.) https://www.multi-module.org/using-the-module/protocol-details

P.S. Unfortunately the "UNIVERSAL" on the T9 website = FCC version and not the "UNI" firmware of Mike Blandford.

Just a thought - some receivers have trouble binding if the Tx is close. Might be worth a try moving the Tx a few feet away when binding. Is there a possibility of an FCC/EU-LBT issue. ? I would presume the Rx, if new, would normally be a V2 / LBT version. And usually there is a label on the box showing this.

I'm not sure this is classed as funny ?

Ditto. Intermediate mode and just pull up for a loop. Not managed a roll yet. Haven't got the equivalent for the acrobatic button on my TX16s. Now on my second T26 Trojan. Lost the first one when I flew across the sun. Never saw it again. I fly Mode 1 and just can't use the included transmitter.

A few of similar planes in our club but no one has managed to fly in expert mode. Generally all fly in intermediate mode. I have set up some very small rates om my TX16S but not had chance to try them out yet.

Have you tried a bit of toe-in on the undercarriage ?

I've had a Radiomaster TX16S Mk1 for a couple or 3 years now. Not had any problem with it at all. It certainly needs a bit of use of the little grey cells to work through its functions but there are numerous YouTube videos on the how-to. The 4 in 1 module (MPM - multie protocol module) is the one to go for if you want to keep your Spectrum dsm/etc receivers. Also will operate a varied number of other makes. Stay away from the Radiomaster standard receivers as they have a mixed history ?

If you want to use your existing receivers will the newer Tx's be compatible ?

Always taken the Tx with me. Not been a rule in our club AFAIK. 27/35 MHz days would normally have pushed the aerial down anyway. Sometimes used the Tx to locate a hidden model in the jungle surrounding the strip, by operating the controls and listening for servo movement.

You can use any battery as long it is the correct voltage.
