flap opperation on my Avanti 80 mm sport

[Benedict3gisla@hotmail,com]

purchased in December 2017. stock set up. noticed flaps would not come up after landing. Occationally one side, usually both sides. If I disconnect battery and re connect, flaps opperate normally. Tried changing channels, sellected new model. new receiver. Replaced relay board as per Motion RC. problem remains. Tried experimenting with servo speed; found that increasing the reverse speed to 100 percent flaps now consistently return . Any ideas?

Have you tried to by-pass the board entirely? Yank out the flap servo leads and use a "Y" and plug directly into flap channel in RX.

I have had the same issue with mine but only one side at a time.Have had 2 (pnp,then arf +). Both very random. Never failed to extend (i take off every time with half flaps ). Never failed to retract half flaps after takeoff. Except for pretty high winds i use full flaps every landing.Had my flaps delayed on first one and a few flights on #2. Set flap to no delay and they have yet to act up. 30-40ish flights since i set flaps 100% speed.
