Review by: Hughw
I bought one of these to replace the elevator servo on a Sebart Su29 e50 v2 ; its a big elevator and to fly nicely needs accurate servo response and minimal dead-band width. I was so impressed with it, I purchased 3 more to replace the rest. The only thing to be careful with is the servo arms (25t) are far too tight and require careful handling. I used a spare 25t servo to wear them in before fitting to the HV737
and used a spare M3 cap head bolt to draw them in as per recommendations on various forums.
