Hi
For about the last month I've been working with Kelvin at Keleo Creations on installing the Saito FG-84 engine with his radial exhaust ring.
Kelvin designed an engine mounting box that replaced the existing firewall. By installing the engine mounting box this made the installation a lot easier. The engine with the exhaust ring now fits in the cowling without exposing the rocker arm covers.

P.S. I’m off to Toledo for the weekend….

Hello Gents,
I have sent an inquiry to Horizon and waiting for a reply and thought I'd get your take also. I am interested in building this 60cc Corsair and I'm concerned as there are a number of the HH parts specific to this airframe that are currently backordered. Do you think HH will continue to support the airframe with parts, retracts, wheels, etc for a while longer or will I have trouble finding parts? Also, the HH website says "price reduction" and still lists the price as $999. Is this the reduced price? It seems like is has been $999 since it was introduced. Thank you for your help as a new RCU member. The excellent information you've shared here is helping me make the decision to build this airplane. Thanks again, Joe

What parts in specific? If you mean the electric retracts, you have to be quick to the punch in order to actually obtain a set. Quite annoying - and more due to Robart than anything. Most of the spares are in stock doing a quick check just on Horizon. If you look around, sometimes other shops have the spares Horizon doesn't have in stock.
I actually think the parts availability for a plane of this "nature" (i.e - there's no way this is one of their highest volume planes) is quite good, outside of the Robart stuff. Which, if you can avoid using Robart gear on this plane... they aren't a complete piece of crap, but if there's one thing I wish I didn't purchase to begin with are these. I'd much rather have tried to retrofit another brand of retracts to the plane anyhow. I finally have mine working reliably however (the electric Robarts) *knock on wood*

Thanks, Chorner. Yes, I was talking about retracts, wheels, tail wheel and actuator. A HH rep got back to me today and the retracts should be back in stock next month.
Another question while I'm typing. If you had a DX18, what would you recommend for a receiver with enough ports for 4 gear door servos, bomb release and maybe lights. Could you use an AR9020 9-channel with an X-Plus expansion module or would you prefer the 9 or 12 channel Power Safe receivers with an expansion module? What would be your preference without going overboard?

I used to have the DX18 setup in my Corsair (before switching to all JR equipment) and I used the 9020 with the X-Plus expansion. I was using 16 channels I believe.
My preference back then was to use the 9020 as it was a combination of something I had, and less expensive in total than the power safe receivers. I just made sure to plug leads from the battery into both the receiver and x-plus module as each JR style connector will supply 4amps max. If I were to do that setup again, I'd probably go for the power safe 9 or 12 channel receiver. Much better amperage and easier to setup since if you do the gear doors and add all the options, there's a lot of current being drawn.

Just think "the bigger the better" in terms of wire size, connector size, battery size etc. without going nuts. In my opinion, you don't need dual batteries, plus an ignition battery etc. some guys even use a separate battery for the electric retracts alone. Keep in mind, the more complexity you put into it, you're also increasing the risk of failure the more components you use to do the same job as well. Not sure if that was totally helpful, but something to think about anyhow! Keep it simple, but robust if that makes sense...

Yes, there is certainly a tipping point where complexity adds to increased potential for failures. Have to also remember that we dealing with airplanes where we need to be counting every ounce or gram. Simple and light is the goal...

I am running the DX18 with the 12 channel power safe receiver and the expansion receiver. Nice part here is the expansion receiver is in the wing and it eliminates a lot of wires to plug in when assembling the airplane at the field. I'm running all high voltage servos so no regulators anywhere. Also running 2 Lipo batteries for power. I have the EVO 7-77cc so I needed nose weight anyways. Even with 2 receiver batteries and a battery for the on board glow I still had to add some nose weight.

Thanks, Edge Pilot, for the good input. I think I read the same in this thread about the convenience of the expansion module. Still haven't decided take the plunge with this bird. Are you running your 7-77 on glow fuel? Any ignition mods?

running on glow fuel. So far I have not seen and gas conversion that is completely successful. I have an onboard glow driver made for the 7 cylinder. Starts and runs to good to worry about changing anything
Also just to update people on the electric Robart retracts, The ones they are selling now are generation 2, way less trouble and issues than the originals. I had a lot of trouble with the originals but now I have the gen II.

Edge, I have a very successful 7-77 conversion. Still running methanol, but spark converted none the less. After about 5-6 hours of runtime on the engine, I'm pulling 6,350rpm with a 24x10 Mejzlik and approx 20% better fuel economy than without.
I would call that successful!

I mentioned two advantages already. More power output, and better fuel economy. I tried to run a 22x12 Mejzlik on my engine and it was turning 7,000 rpm when breaking in and quickly stopped running it. On glow the 22x12 pushes 6,200rpm when fully broken in. Not sure how you're barking the tips on a 22" prop at 6,200rpm and under... How do you tune and fly without checking your rpm? The third advantage is reliability, and I guess that could be up for debate but hand starting is incredibly easy, and the amount of power it takes to run the ignition is minimal compared to constantly powering glow plugs.
P.s- one more advantage is that with my JR 28x and the JR ignition kill switch/RPM telemetry unit outputs the rpm in real-time on my transmitter hooked up to the ignition, so I always know what rpm the engine is pulling at any given time.
All the same reasons the high end YS engines run CDI on their 4 stroke glow engines.
