Installed an RCA2610 in place of the turn coordinator on my Cessna 340A. Great looking backup attitude indicator without all the clutter of other flight instruments (i.e., airspeed, altitude, vertical speed). And super simple install with just two wires and existing 3.125 standard hole formerly used by the turn coordinator plus a change in the circuit breaker (reducing from 5 amp to 2 amp). Bought the zero tilt unit but then discovered the C340A needs an 8 degree tilt. Called RC Allen and they recalibrated my unit to an 8 degree tilt for no charge except shipping. It is a year later and now the unit comes with digital turn coordinator. Called RC Allen again and my newer unit is upgradable to add digital turn coordinator and they are doing it just for shipping costs. Fantastic customer service with a really great product.

Works fine but look at the picture, no slip ball so I bought an external one for $149 and when I turned it on it has a digital one. $149 wasted

Added the RCA 2610 to my Piper and I love it! Its easy to get used to, it reliable, and accurate. The installation was easy, adding the back up ESP took a little time to find a great location but worth the time. I only wish that RC Allen charged a little less for the unit, but it is a great competitor to the G5 and if you want is the AI then there is no reason for adding all of the extra work for the G5. Now my next upgrade will be the RC Allen HI.

I give it 5 stars, but I havent flown with it yet. The installation was straight forward (with an A&P, of course). The only change I had to make was the circuit breaker switch. The old was 5 amps and we installed a 2 amp as called for in the instructions. The only down side is the cost. Not worth the extra thats added on because its certified.

So far it is nice. Replaced our turn coordinator with the RC2610. Screen space is a bit smaller than traditional AI but outstanding backup to a Vacuum AI. Only issue we had was, the tilt. We thought tilt was the amount of adjustment you can get with the up down arrows. It is not. It is for someone with a panel that is tilted 8 degrees. (Not sure who has that). No applicability list that recommends proper AI for your aircraft. Asked Aircraft Spruce for swap but they are not able to be cause we placed it in the panel. We were advised to sell on e-bay. We called RC Allen and they are going to adjust ours to zero tilt for additional $200. Expensive mistake on our part but at least a better solution than eating the price of a new one or the loss of value by selling on E-Bay. So it works nice but, be careful which unit you buy. It is yours period.

It gets 2 stars because it looks good....What a rip-off otherwise. 2 year warranty....? Wow! I paid for that warranty up front...Should be a free replacement...
