I ended up fairly forward of recommended (which is unusual for H-9 planes, they are generally conservative)

My buddy went with a self starting VV40 and the extra weight was perfect. I ended up with more lead than I would have preferred.

My guess is they did the testing with an AS3X receiver and it masked the rear CG

interesting and yes most H9 models are way too nose heavy based on what the book states.

I'll fly mine for a bit, do some staight line runs and cut throttle to see what it does, gradual decent = ok, sharpish decent then nose heavy, pitches up then it suggests tail heavy.

Did you use any aileron differential? Mine has a bit of adverse yaw but as I am out of channels on the 9ch Rx I might just have to mix a bit of rudder in or use my thumb which is what I normally do anyway.
Can always use a JR matchbox and limit the down end points for each aileron.

cheers

I just finished up one plane and so now the RV-4 is on the bench. Quick question. What are you guys using for a simple controller for the lights? I want to tie them into the flaps so that when flaps down, lights on. Thanks in advance.

I use the Rxcel opto kill switch. Same type of unit that I use for the igntion kill.
Use a seperate battery, have the Rx lead go to a spare channel and do flap to that channel mix or just use a Y lead off the flap channel.
The unit is an opto coupled sold state relay. Rx triggers it to on and allows current flow from the seperate battery. Do not use your flight batteries.

clear as mud?

Now have over a dozen flights and getting landings dialled in, think I need maybe another 2% down trim in the flap / elevator mix. Will play with that for next time I take it out.
The Evolution 33 is slowly starting to loosen up, probably about 3L through it so far of 20:1 mineral mix fuel. Once I have put another 2L through it I will swap to a 5 L can of 30:1 mineral & then will move to 30:1 synthetic.
Castrol TTS 2 stroke racing bike oil.

Also while unpacking everything I noticed they sort of did the fuel tank stopper at the factory. Is the factory stopper gas compatible? I'm use to the redish stopper for gas. Just curious. This is my first gasser in a long time since everything else I own has a turbine now. Also, been considering using a DLE 35 rear exhaust but was curious what people think of the evolution engine that H9 recommends. I have always has great luck with DLE's but just wondering about the evolution 33.

as the model is designed for the Evo 33 which is petrol (gas) I would suggest yes t is compatible. Also as I have a dozen or so flights on mine without issue this is further evidence.

I believe the manual also states that . . .

Did any of you have problems with the canopy fitting? This is my first gas plane in a while since I went to all turbines but I liked the look of it. After going over some of the parts it seems H9 has lost some quality on their build up planes. I use to own several H9 planes and loved the quality and parts fit. This one has me a little disappointed. Just hope it goes better once I start assembling
