Yes, The basic stuff will be just fine.
Being your building you can decide overall strength and wieght. I think light planes are much more enjoyable to fly. So the lighter engine means better landing performance, slower flybys lower cost and operation.
Lighter is better.

Lifer, those numbers add a lot to your posted info.
drube, yes your wing area is helpful to.
I used to fly a GP Giles 202 a lot. It was 72in ws 12.5 lbs and 970 square inches. I flew it with a pumped Super Tiger 2300 glow (1.4 cu in). The ST swung a 17x6 APC at 11k so the performance was good but the high wing loading made it a handfull. Many of those were flown at our field (mostly Moki 1.35s). That high wing loading resulted in a short life for most of them.

1120 sq in is my wing area, What kind of flight performance should I expect? Oh wait.. My wing loading is 20.5 oz/sq ft. Is that good?

I have an airlplane with 1120 squares that wieghs 14 lb. It flys like a kitten and lands at a walking pace. So your wing loading should not be a problem.

DLE 20RA in a Goldberg Super Chipmunk .60 size kit
This plane has 2-12oz. tanks. One for smoke oil and one for gas. It weighs in at 8.8 lbs. and balances out perfectly. I added flaps when building and she glides in nice and slow. I am still getting used to the flaps and the amount of throttle to land it. I am using the Sullivan Skywriter pump for smoke, flightpower voltage regulator, and running the whole system on 1 2550 mah 2s lipo. I am using the stock motor mount and the firewall is routed out so the carb sits partially into the firewall. I'll try to get some good video, right now I only have some cell phone footage. The first three flights were with an APC 16x8 prop and that worked well, motor turned 8500 rpm's. I did not like the plastic look so I went to the XOAR 16x8 and on take off she torques left real bad and only turns 8100 rpm's. The motor is rated at 9000 rpm's. I would like to stay with a wood prop and get rid of the torque on take off. And suggestions on a wood prop and size? I am guessing I was gonna try a 16x6 next.
Thanks,
Alvin

[Agree with LIFER try an Xoar17x 6. I won't get you to the 9,000 rpm that tou staed, but it will give you more thrust..I'm getting 8850 rpm's & 14# 14oz to 15# 1oz of static thrust

I just ordered DLE 20 number five. So that will be 20's installed in top flite corsair, sea fury, p-51 , P-47, and a seagull super decathlon. These are awesome little engines on a 60 warbird.

Taildraggers are going to torque to the left while the tail is down. Add power slowly until the tail is flying, then add power slowly until you are flying at what ever speed you want to go.
No matter what plane you fly, the throttle should be moved smoothly. Learning to move the throttle smoothly and deliberately makes you a better pilot (especially on taildraggers).
Try painting whatever prop you like best for a more scale look.

Thanks for all of the advice guys. Not sure if I have enough ground clearance to go to a 17" prop, but I will check. If not would the 16x6 show any noticeable difference in torque over the 16x8? I do currently use rudder, it's just that this plane in particular over all of my other taildraggers torques the worst. It is also probably my most overpowered plane. My 24% edge 540 by Pilot RC takes off nicely with the dle35 and 19x10 prop.

I would think the 20 would be under propped with the 16-6. I don't think you would get the airplane performance you expect with that prop. You might try a three bladed prop if ground clearance is an issue. Too bad you can't make the 17-6 work as these engines really seem to like that size.

I plan on flying it tomorrow. I will check ground clearance then. As far as a three blade goes I think I read somewhere where a 15x7 three blade is recommended for that engine.
