Default F-4 raider/Harmon Rocket Lite

I don't post much here, but last month I managed to adopt Larry Vetterman's Harmon Rocket lite,(as he calls it) that was converted to an IO-360 instead of the popular 540. After searching, it looks as if there has been a fair amount of interest over the years, So I thought I would start a thread about flying, and modifing this rocket lite.

I plan on trying to wear it out this fall and winter, and I will be posting on its flying qualities and performance numbers, as well as try to answer questions that people might have about the combination.

Greg

Default Rocket 100 SARL Race

If things go right I am hoping to go to Texas and participate in the rocket 100 air race on nov 11. That way I can get some official performance numbers for all to see.

I'm also hoping to meet some fellow rocketeers and learn some about the big engine ships..

If I try to embed these pics they either don't show up at all or they are way to big.

Default F4 Raider

I'm very interested in the F4 Raider. Before seeing the pictures from Oshkosh I didn't even know they existed. Seems like a perfect combination with the IO-360 up front. I don't have the room or budget for two planes so I have to decide if I want to give up my -4 to move forward. Having all that extra room would sure be nice though. I love the way the -4 handles but it is a rather snug fit, limited panel space and requires some attention to Wt & Bal when you have a back seater. I've gone as far as I go on a budget without putting in a full glass panel. Wish these were around when I got the -4. Hopefully Vince will go forward and eventually have a full kit.

Very tempting........

Looking forward to hearing the numbers/PIREP. I keep drooling over Rockets (and a bunch of other planes) daily. Jealous!

Default Weight and balance

Weight and balance has been a pleasant surprise. Empty weight on this plane is listed as 1091 lbs, which I understand is about the same as a heavy RV-4. I had a polished RV-4 before this, its builder was very weight conscious, to the extent that he didn't paint it, or install lights, with a Catto fixed pitch two blade prop, and it weighed 980 empty. The rocket was built light, but not to the same extreme.

With the rocket I get a gross weight increase to 1950 lbs. according to weight and balance calculations it is still aft cg sensitive, but in practice it is much less pitch sensitive than the -4. With 2up the rocket is comfortable in pitch and the trim is right in the middle if its travel where as the -4 was trimmed full forward in cruise and very pitch sensitive on landing, but that probably has more to do with the difference in props than the difference in airframes. the rocket has a BA
