Its the next one up from that radio in the pic for just £10 more, I heard the receivers by hobbywing work (there like a £5 if i remember correctly with this not sure about which ones but i am sure someone on here will know.
Like other people have said shop around MB models have that kit posted for £10 less.
Happy shopping, post again with an update
p.s an aluminum front pin brace may be a good option, I have the b5m and have found that the plastic pin brace edges can crack in a crash putting all the strain on the bulkhead which breaks the bulkhead. Broke 3 bulkheads this way (only real weak point ive found with b5m) switched to aluminum one 6 months ago haven't broke one since. jconcepts do one for £9 ish team associated do one foe around £11.
P.P.S not sure if this is useful or not to you just found it other day
